Three B-Complexes: The Worst Dressed, Best Dressed, and Fairest of Them All



Most people purchase supplements believing that the nutrients in them will benefit their health. Many do not know where the nutrients originate or about other ingredients lurking in those tablets and even in many powders and capsules. There appears to be so many choices on the store shelves, but are there really? Before we look in on our three B-complex supplements, let’s take a look at what these supplements consist of and what the choices really are.

Synthetic vs. Natural Most vitamin supplements found in drug and health food stores do not contain vitamins that are truly natural, but are synthesized predominantly from petrochemicals and less frequently from plants. These are manufactured by six companies that are the sole producers of all the raw materials, which end up in the vast array of synthetic dietary supplements seen on store shelves. Also, only a small number of supplement companies, about 3%, actually manufacture their own products. The raw materials are purchased and a super assembler assembles the formulas for them.
There are three basic types of supplements: synthetic, crystalline, and whole food. These are available in numerous variations and combinations.

Synthetic vitamins are those that have been developed the laboratory. They are isolated chemical versions of vitamins. Crystalline vitamins originally had a natural food source, but have been extracted and isolated by processes that may have involved substances such as chemicals and solvents and high levels of heat. The crystalline vitamins, in the end, are much like the synthetics. "Whole food" vitamins are those that have been carefully processed and unaltered in any way that would change the molecular structure or biochemical combinations and actions of the vitamin complexes.

Many supplements claim to be "natural," but what does this really mean? To earn the right to be labeled "natural," supplements need only to originate from a natural source and/or be as little as 10% natural. Many supplements that are called natural have a food base but the primary ingredients are USP or synthetic vitamins. These would contain some co-nutrients that may assist the body in assimilating the vitamins in them.

There are companies who "grow" their vitamins in a "thick soup" of yeast and whole foods but the "nutrients" that are grown in this manner actually start out as USP (synthetic) vitamins. Nothing is going to change them from synthetic to whole and natural. Even supplements derived from natural sources such as herbs, yeast, foods such as rice bran, liver, berries, or bone can be dead and useless due to heat, pressure, or other processing techniques that destroy their enzymes. The way in which the materials are processed is extremely important in preserving the integrity of the nutrients contained therein.

Chemically, natural and synthetic vitamins are identical. The same ingredients are contained within the molecules but they are arranged in a different fashion. When a beam of polarized light passes through a natural vitamin it will always bend to the right, due to the molecular rotation of the natural substance. The letter "d" seen on some supplement labels represents dextro or "right." This indicates that the vitamin is the natural form.

As a beam of polarized light passes through a synthetic vitamin it splits into two parts, one part bending to the right and the other to the left. The synthetic supplements may be represented by the letters "dl" preceding the vitamin name. The "d" for dextro and the "l" for levo or left. This demonstrates that the molecular rotation of the synthetic is not identical to the natural form. The biological activity of synthetic vitamins can be 50% to 70% less than nutrients in natural, whole food supplements.
B vitamins are not generally referred to in conjunction with these letters but the difference in molecular structure between synthetic and a truly natural substance applies to them as well as any other nutrient.

Whole food supplements and some "natural" supplements will give foods as sources for the nutrients they contain. 

If a supplement is synthetic it will usually show the following as sources:
B complex – no source listed
B1 – thiamine mononitrate or thiamine hydrochloride
B2 – riboflavin
B5 – calcium D-pantothenate
B6 – pyridoxine hydrochloride
B12 – cobalamin
Folic Acid – pteroylglutamic acid
Biotin – d-Biotin

There is much controversy concerning the body’s reaction to synthetic vs. natural vitamin supplements. Many believe that the small differences between synthetic and natural are of no consequence. However, clinical evidence and several studies indicate that the body detects the difference and that natural forms of vitamins including A, B-complex, C, D, and E are more absorbable and assimilable by the body and have a more profound effect on deficiencies and disease than synthetics. This question comes to mind: Isn’t it possible that this could be true for all nutrients? Also, it has been shown that sensitive individuals who have reactions to the synthetic vitamins can take the truly natural forms with no problems.

There are some very real problems with synthetic vitamins and most supplements containing them. Not only are they synthesized, but are also isolated components completely removed from the family of micronutrients that accompany them naturally in whole foods. They are not intact with their co-factors such as enzymes, co-enzymes, vitamins, minerals, amino acids, trace elements, proteins, phytonutrients, and essential fatty acids as they would be in whole foods or properly manufactured whole food supplements. 

They cannot possibly have the synergistic, nutritional effect of the whole food vitamins.
Think about it! How can a dead, isolated, chemical supplement have the same action in the body as a live, whole, food concentrate? The human body was designed to recognize and utilize whole, live food not isolated chemicals. It is obvious however, that the synthetic supplements do have an effect on the body and even appear to be beneficial, at least initially.

Chet's CommentsKaren Railey, the author of this piece on B vitamins, writes some of the best and most detailed articles and eBooks in the Natural Health Movement. 

In fact, synthetic isolates will draw the accessory nutrients needed to assimilate and metabolize in the body, from the body’s stores. It is possible for this anomaly to create deficiencies of other nutrients, or if a person is already deficient, synthetic isolates may further deplete the body and eventually cause larger and more serious imbalances.

It is not logical to expect a chemical to build the body in a nutritional sense. It is my belief that synthetic vitamins have a pharmaceutical or medical effect and whole foods, super foods, and natural whole food supplements have a nutritive effect and help to build the body’s cells nutritionally. There may be times when either may be useful, however, for the long term a truly natural supplement would be best.

There is some debate concerning whether the synthetics or the naturals work better for severe deficiencies or conditions where a quick therapeutic result is needed. There have been reports of good results and poor results with both, but according to Dr. Richard Murray synthetic vitamins fail time and time again when put to the scientific test in human feedings. Over 200 studies have proven the superior efficacy of whole foods and whole food supplements as compared to the synthetics.

Supplements made from whole food concentrates will often have lower nutrient amounts listed on the label. Due to the fact that more of the nutrients will be available to and utilized by the body from this type of supplement than from the synthetic supplements, I don’t believe that this is of principal concern in most cases.

What I consider as natural in the fullest sense of the word are those supplements concentrated from whole foods and processed in a manner that keeps all nutrients intact with all the co-factors and preserves the life of the enzymes in the concentrates. This type of supplement is generally more costly and difficult to manufacture, so consequently they are often extremely hard to find.
Let’s take a look at some of the ingredients that are included in vitamin supplements aside from the nutrients.

ExcipientsThe term "excipient" refers to materials used in tableting or encapsulation of nutritional supplements for any purpose other than its physiological effect. These range from natural and harmless to chemical and potentially problematic, particularly for sensitive individuals. In other words…some of these do have physiological effects even though that is not their intended purpose.

Fillers: These are used to increase the volume of material in a tablet or capsule to aid in easier processing. Tablets and capsules are generally made in only a few sizes so fillers are added to take up space in the molds or capsules.

Some of the common non-food fillers used are talc or silicon. These may cause problems with digestion and absorption. Food grade fillers include cornstarch, lactose, cellulose, sorbitol and calcium phosphate. There is a possibility that these may cause allergic reactions or sensitivities.

Binders: Binders are various compounds that are used to adhere all the components of tablets together. They are the base of many supplement tablets and include lecithin, honey, sorbitol, gum arabic, and cellulose. Gum arabic has caused asthma attacks, rashes, and allergies in some individuals.

Disintegrants: These are added to many supplements to aid in the disintegration of the tablet within the gastrointestinal tract by swelling and breaking the tablet apart. Most of these are made from cellulose.
Lubricants/Flow Agents: The use of lubricants aids in the release of tablets from molds and ensures unrestrained movement through the tableting machinery, making the manufacturing process smoother. Lubricants and flow agents such as magnesium stearate, calcium stearate, and stearic acid may be used that increase the time tablets take to dissolve thus, may reduce the bioavailability of the nutrients in a supplement. Other common flow agents are vegetable stearin and silicates such as silica.

Flavoring agents: Sweeteners commonly found in supplements are sucrose, fructose, maltodextrin, sorbitol, and maltose. Usually sweeteners are used in liquid, powdered, chewable, or sublingual supplements. Stevia may be found in a small number of supplements but will not be labeled as a sweetener due to FDA regulations prohibiting its use as a sweetener in foods or other products. Artificial or natural flavoring may also be added to supplements.

Coloring Agents: A pleasing and uniform appearance is the motive for adding these to supplements. Some of them are derived from beets, carrots or chlorophyll, but others are synthetics, which are often questionable as far as consumption and health are concerned.

Coating Materials: The reason these substances are used is to mask unpleasant odors and flavors, aid in swallowing the tablet, aid in preventing tablets from breaking apart and to protect them from moisture. A commonly seen coating material is listed on labels as pharmaceutical glaze, confectioners glaze or natural glaze is actually shellac. A supplement coated with shellac cannot be broken down or assimilated.

A vegetable protein coating (zein), which is derived from corn and Brazil wax is sometimes used as well as a coating made from palm trees.

Preservatives: There are companies that use natural preservatives such as vitamin C or E in their tablets. Tablets do not need added preservatives if they contain these or vitamin A, cysteine, methionine, or the minerals sulfur and selenium as they are all natural preservatives.

Capsules can be made without the use of excipients but are not always excipient free. Capsules are usually made from gelatin and are an animal by-product. There are some vegetarian gel caps available that are made from potato extract, however these are used by only a small number of companies.

Another interesting angle to think about. Some companies actually make tablets, crush them to a powder, and then encapsulate them. In this case you could still be getting some of those excipients inside the capsule! Powders may also contain excipients such as flow agents, sweeteners, colors, and/or preservatives.

Now, let’s take a close look at three different B-Complex supplements. The first two were chosen from what is available at drug and health food stores and the third is available only through health professionals. In all fairness it should be noted that tablets couldn’t be made without the use of some excipient material. Judge for yourself what is excessive and which would be the best for you.
Worst Dressed YourLife B-ComplexCost: $5.69 for 100 tablets.

Label: Each tablet provides:
Thiamin (Vit B-1) 10mg
Riboflavin (Vit B-2) 10mg
Niacin (Vit B-3) 10mg
Vitamin B-6 10mg
Folate 100mcg
Vitamin B-12 10mcg
Biotin 10mcg
Pantothenic Acid (Vit B-5) 10mg

Listed Ingredients:Thiamin Mononitrate (B-1): This is not the most commonly used form of B-1 used in supplements. Thiamin hydrochloride is the form of vitamin B-1 that is used in most dietary supplements.

Riboflavin (B-2): Vitamin B-2, or simple riboflavin. Interacts closely with thiamin.
Niacinamide (B-3): Vitamin B-3 in the form of nicotinamide.
D-Calcium Pantothenate (B-5): The most common synthetic form of vitamin B-5 or pantothenic acid. The most active and useful form is panthethine.

Pyrodoxine Hydrochloride (B-6): A synthetic form of vitamin B-6 that is often used as a coating in the manufacture of supplements to mask taste and odor.

Folic Acid: Available as folic acid or folinic acid. To utilize folic acid the human body must convert it to tetrahydrofolate then add a methyl group in order to form folinic acid. Supplying the body with folinic acid would bypass this process.

Cyanocobalamin (USP Method 2) (B-12): This is the most common form of vitamin B-12 but is not an active form, nor the best form to use. Methylcobalamin is the most beneficial synthetic form of B-12.
Biotin (USP Method 2): This is the isolated form of biotin. Biocytin, a biotin complex from brewer’s yeast is also available.

Para-Aminobenzoic Acid: PABA is a member of the B-vitamin family and is part of the folic acid molecule. PABA is said to aid in the assimilation of pantothenic acid.

Calcium Carbonate: An insoluble form of calcium found in nature as calcite (in limestone, marble, or chalk), aragonite (pearls), and in plant ashes, bones, and many shells. It is often used as a binder in supplements. It is not absorbable by the human body and may cause constipation.

Maltodextrin: An unfermentable sugar obtained by the hydrolysis of cornstarch. It is used for flavor, as a texturizer and bulking agent. Maltodextrin may contain free glutamic acid (MSG), which occurs as a result of processing.

Hydroxypropyl Methylcellulose: This excipient is a vegetable gum, which is commonly used as a main ingredient in artificial tear solutions. It is resistant to bacterial decomposition and is used as a disintegrant and emulsifier in this supplement. At this time there is no known toxicity.

Cellulose Starch: A starch made from plant material that is used as filler, binder and disintegrant. Starches processed from corn contain free glutamic acid (MSG), resulting from processing.
Croscarmellose Sodium: This material is a distintegrant derived from vegetable fiber.

Sodium Starch Glycolate: A disintegrant that is made from potatoes, maize, wheat, rice or tapioca starches. It is used in tablets containing insoluble ingredients such as magnesium stearate to help them break apart. If processed from corn, this starch will contain MSG.

Silicon Dioxide: Silica, a transparent, tasteless, powder that is practically insoluble in water. It is the main component of beach sand and is used as an absorbent and flow agent in supplements. It is also used in ceramics and scouring and grinding compounds.

Hydroxypropyl Cellulose: A vegetable gum commonly used in opthalmic applications. It is used as a disintegrant and emulsifier in supplements.

Red 40 Lake: An insoluble pigment used in food, drug, and cosmetics applications. The National Cancer Institute reported that p-credine, a chemical used in the preparation of Red No. 40, was carcinogenic in animals (Consumer’s Dictionary of Food Additives, Ruth Winters, M.S., pg.185).
Polyethylene Glycol 3350: This excipient is used as an emulsifier, binder, and surfactant. It improves resistance to moisture and oxidation. Polyethylene is a polymerized ethylene resin and glycol is a dihydric alcohol.

Magnesium Stearate: This commonly used excipient can be made from animal or vegetable sources. It is used as a flow agent and surface lubricant. It is insoluble in water and said to be non-toxic but may hinder the absorption of nutrients.

Resin: Resins are used as binders and aid in water resistance. They may be of plant or synthetic origin and are used in lacquers, varnishes, inks, adhesives, synthetic plastics and pharmaceuticals. Synthetic forms include polyvinyl, polystyrene, and polyethylene. Toxicity is dependent on the ingredients used in the manufacture of the resin.

Dicalcium Phosphate: A mineral complex of calcium and phosphorous that is commonly used as a tableting aid, filler or bulking agent. Phosphates can induce the same symptoms as MSG in those who are extremely sensitive to MSG.

Polysorbate 80: A non-ionic surfactant that is a polymer containing oleic acid, palmitic acid, sorbitol, and ethylene oxide and is formed by microbial fermentation. It is used as an emulsifier, dispersant, or stabilizer in foods, cosmetics, supplements and pharmaceuticals.

Titanium Dioxide: An inorganic, white, opaque pigment made from anatase (from minerals) that is often used in supplements as a whitening agent. It is also used in paints and coatings, plastics, paper, inks, fibers, food and cosmetics. Titanium Dioxide is an oxidant.

Povidone: PVP is a synthetic polymer used as a dispersing and suspending medium.
Pharmaceutical Glaze: Shellac used by some manufacturers to coat vitamin tablets. Shellac is insoluble in stomach acid and supplements coated with shellac are difficult for the body to break down and assimilate.

Suggestions for use: Take one tablet daily with a full glass of water, preferably after a meal.
Chet's CommentsKaren Railey, the author of this piece on B vitamins, writes some of the best and most detailed articles and eBooks in the Natural Health Movement. 

This supplement is very inexpensive but it isn’t even worth its modest price.
The nutrients in the YourLife B-Complex are isolated synthetics and some of them are the least useful and/or least absorbable forms of the vitamin. All the amino acids and minerals that are needed to assimilate the nutrients that are in the tablet will be taken from the body. By the time the body deals with this, the fact that some of the forms used are not the most bio-available, and the various excipients in the tablets, some of which impede absorption, only miniscule amounts of the vitamins will be available to and assimilable by the body.

Nutrient levels in this supplement, though they do exceed the RDA, are very low if they are to be taken per label instruction. With these levels it would be better to take a tablet 3 to 5 times a day.

The YourLife B-Complex contains 18 different excipients and only 8 nutrients. This is a very lopsided picture. One would be ingesting more excipients than nutrients if taking this supplement. The pills are glued together with binders and coatings then have disintegrants that are supposed to disintegrate the tablet from inside out once consumed. Some of the excipients may cause allergenic responses in sensitive people and who truly knows what the long-term effect of ingesting them are.

In 1976 the Journal of Food Science carried an interesting report. When rats were given three different additives, one at a time, they stayed well. When they were given two additives at the same time they became ill. With a three additive combination they all died within 14 days.

Even if many of these excipients have been tested for toxicity, they have generally not been tested over long periods of time, nor have they been tested in combination. Aside from this, everyone is unique in how his or her body processes chemicals and responds to them.

This B-Complex contains no co-nutrients such as amino acids, vitamin C or magnesium to aid with the absorption of the nutrients. It does contain some PABA, which may help in the absorption of pantothenic acid.

Inositol: This nutrient is part of the B vitamin complex and is found in lecithin. It acts as a mild lipotropic agent in the body, helping to emulsify fats.

Coenzyme Q10: There are 10 types of CoQ and CoQ10 is considered to be the main active one in humans. Ubiquinone is an electron carrier and is extremely important in the cell mitochondria, where it assists in the production of ATP (adenosine triphosphatase) and ultimately helps to generate energy.
The supplement’s base consists of Mannitol, Sorbitol, natural orange & licorice flavors and sodium citrate.

This supplement is suitable for vegetarians and is hypoallergenic. It contains no yeast, dairy, egg, gluten, corn, soy, wheat, sucrose, starch, preservatives, artificial color, flavor or fragrance.
Mannitol: A sweet alcohol that occurs naturally in beets, celery and olives and is also synthesized from hydrogen and glucose (corn sugar). Mannitol is used primarily as a thickener, stabilizer and sweetener.
Sorbitol: Sorbitol is a natural sugar that is found in fruits such as berries, pears, plums, apples and cherries, and sea vegetation. It can also be synthesized from dextrose (corn sugar). Sorbitol is used for many applications: it is a thickener, humectant, texturizer, sequestrant, stabilizer, and sweetener.
Mannitol and Sorbitol are generally considered as safe, but there are some things to consider before using products containing them.

Sorbitol is contraindicated for diabetics. Also, Earl Mindell, in his book Safe Eating, claims that Mannitol can cause irritation to the intestinal tract such as cramps, bloating and diarrhea when taken frequently, in large quantities or in those with gastrointestinal problems.

The combination of the two can increase tooth decay by promoting the growth of Streptococcus mutans, a bacterium that sticks to the teeth. The bacteria are usually harmless but when combined with Mannitol and Sorbitol it promotes tooth decay. Brushing the teeth after taking this supplement will solve that problem.

Source Naturals states that there is a very small amount of Mannitol and Sorbitol in their enzymated B-complex.

Natural orange and licorice flavors: These are natural flavorings and will not generally present any problems. However, it is possible for them to contain small amounts of MSG as a result of processing.
Sodium Citrate: This excipient is extracted from citrus fruit or can be made by fermenting crude sugar. It occurs naturally in citrus fruits, tomatoes, coffee, apricots, peaches, pineapples, and some berries. Citric acid has been used for many years and is considered as a safe food additive, however, it is possible for it to alter urinary secretion of drugs making them less effective or more toxic. It is used to enhance flavor and add a tangy taste to products as well as being used as a buffer and sequestrant.
Suggested Use: 2 to 3 tablets daily or as recommended by your health care professional. Place tablet under the tongue and allow to dissolve slowly, altering the position of the tablet to avoid prolonged contact with the same area.

Coenzymate B Complex is a fairly expensive supplement. Let’s take a closer look at it.
This formula contains the B vitamins in their coenzyme forms; this means that they are already attached to the amino acids and mineral cofactors needed to make them biologically active. The body, specifically the liver, doesn’t have the task of converting the nutrients to their active form before they are available for use by the body.

This supplement is sublingual so the nutrients go into the bloodstream immediately as they are dissolved under the tongue. Because the tablets do not go through the digestive process, where much of the nutrient value of a supplement can be lost, a greater percentage of the nutrients are available to the body. With the coenzymate form of the B vitamins, you’ll need to take only half as much as you would of a standard B vitamin (Julia Ross, The Diet Cure, 1999).

Coenzymate B-Complex also contains Vitamin C and CoQ10, which helps with the absorption and assimilation of the B vitamins in the tablet.

Taking 2 to 3 of these tablets a day will provide ODA’s (optimum daily amounts) for B-12 and folic acid, two nutrients that Americans are typically deficient in. B-12 is in excess of the ODA, which would be excellent for those deficient in B-12, vegans and those who eat animal products in minute amounts. Others may find one tablet a day to be enough. The formula includes all the B vitamins, which is important because they work together and need each other to perform their individual, specific tasks in the body.

The nutrients in this B-Complex are synthetic but the supplement has been shown to be effective and is recommended by a number of people including Julia Ross, MA who practices at Recovery Systems, a California clinic. Because Coenzymate B-Complex can’t be used by diabetics and some people may be sensitive to Sorbitol, an alternative recommended by Ms. Ross is Country Life Coenzyme B-Complex capsules.

It still remains that this is a synthetic supplement and its effects will be that of a synthetic and not of a whole food supplement.

It is important to note that supplement manufacturers are not required to list all excipients of a product on the label. It may be necessary to contact the manufacturer to find out what is in the supplement aside from the nutrients if the other ingredients are not listed.

Most manufacturers are willing to answer questions about their products, however some may be uncooperative. Such was the case with Source Naturals. I spoke to a customer service representative who was very uncooperative. She didn’t want to take the time to answer questions and told me that the company did not send out full disclosure statements, monographs, certificates of analysis, research abstracts, or technical sheets to anyone, even health professionals.

When asked, she did tell me that they made most of their own supplements right there and that "of course, they tested all substances when they came in, and tested lots during and after manufacture." She seemed rather defensive about this. She did offer to send me some standard information of their enzymated B Complex, which she did.

The NutriPlex B Food Complex is reasonably priced and of good quality. It is truly what it claims to be…a whole food concentrate.

The label is quite different from what we are used to seeing; there are no separate vitamins or milligram amounts listed. This is because the supplement is made from concentrated whole food and not isolates or chemicals. The nutrients in this supplement are an entire B complex, which includes all the B vitamins intact with all the other nutrients that are with them in nature. You are getting 300mg of a complete B complex in each tablet.

I spoke to Vic Shayne, PhD, who founded NutriPlex two years ago. He and his wife, seeing the rarity of properly manufactured, truly natural whole food supplements, made the decision to develop their own. Dr. Shayne was friendly and helpful, freely answering my questions. He assured me that their products are chemical free and that care is taken to use those excipients that are less likely to inhibit the dissolution rate of the supplement or hinder the assimilation or metabolism of the nutrients by the body. Proper manufacturing processes insure that the enzymes in the products remain alive and intact.

These supplements are made from organic (both certified and non-certified) vegetables and any animal products used are acquired from New Zealand cattle that are not given antibiotics, pesticide laden food or growth hormones.

This product contains glandulars so would not be acceptable for those who are strict vegans. Vitamin B-12 is not readily available from vegetable sources so this leaves a choice to be made: Take synthetic B-12 or take natural supplements containing B-12 derived from animal products.

The clinical results obtained with the use of NutriPlex supplements have been encouraging and many people have benefited from their use. These supplements provide a way of obtaining concentrated whole food nutrition that the body recognizes and can easily utilize. B-Food Complex provides all natural food sources of the complete vitamin B complex and its synergists including enzymes, coenzymes, minerals trace minerals, and amino acids.

These supplements can be taken indefinitely and without concern for toxicity, which is often a consideration with long term and/or high dose usage (over the therapeutic doses) of many synthetic vitamins.

The B vitamins are vitally important in supporting the brain, maintaining proper function of the nervous system, endocrine system, digestion and elimination, enzyme systems, and the liver, heart, kidney and other organs. They assist in blood sugar regulation, protein, carbohydrate and fat metabolism, building red blood cells, hormone regulation and production, the maintenance of mucosal, epithelial and eye tissues, normal growth and development, and more.

This whole food B complex makes available to the body an excellent and recognizable form of the B vitamins, which will be of great nutritional benefit in supporting the aforementioned functions and systems.

Suggested Use: 2 to 4 tablets daily or as directed by a health care practitioner. Some of the literature recommends chewing or breaking up the supplements for best results, though this is not stated on the product label. They don’t taste bad either!

Diet and SupplementationThe extreme importance of responsible, healthy food choices and eating a diverse properly balanced diet as a number one priority must be emphasized here. The next step would be to address juicing and booster foods including products such as green foods (barley grass, wheat grass, chlorella, spirulina, etc.); Living Food, bee pollen, kelp, nutritional yeast, and stabilized rice bran to add needed nutrients to the diet. Then as necessary, supplements should be added to the protocol. It is difficult to get all the nutrients needed from food alone, particularly in the case of a deficiency, condition, or disease state where food and even booster foods cannot provide enough nutrients to produce the needed therapeutic effect.

It is important to remember that health will never be optimum if an unhealthy diet is consumed and lots of supplements taken with the idea that the supplements make up for eating poorly.
There are no completely perfect vitamins out there so we must choose from the myriad of choices that ironically, offer so few choices and learn to distinguish the "worst dressed" from the "fairest," and make decisions concerning what is best for us and our health. Remember…a supplement is only as good as its ingredients.

Vitamin A and Carotenes

I hope you might be able to answer my dietary query. I have recently lost a lot of weight- over 100 lbs. In order to do this, I have been eating loads of carrots, as I need to eat something when I am stressed, which is quite often.
When I recently went to the doctor, they commented that I looked tan / orange. I am, I suppose, eating so many carrots that I am over dosing on beta carotene. I read your Q & A on beta carotene and it was talking about not taking too many vitamin A or beta carotene supplements, but to eat fresh veggies instead. So the question is: is eating loads of carrots bad for me (I probably eat a pound a day)? Do I need to stop completely to get rid of the slight orange tint? How much can I eat and not turn orange? Also, my other veggie of choice is pickled beet root. Will that contribute to my coloring as well? Do I need to stop eating that as well - nightmare! What veggies can I safely eat large quantities of?
I hope you can answer my query. Thank you very much. I enjoyed your Healthy Body Calculator very much, and have recommended it to others.
Hey, big congratulations on the weight loss! You are one success story.
With regards to carrots, yes you can eat so many of them that your skin will turn yellow. One carrot (7 1/2" long) has 2025 RE of vitamin A, which is 203% of your Daily Value. One pound of carrots has 1276% of your RDA for vitamin A. So since you have eaten more than 3 carrots in a day (> 34,000 IU), you have probably saturated your body's ability to store vitamin A over a short time and so it is showing up as an orange tint on your skin. I would suggest you decrease your carrot consumption and increase other low vitamin A vegetables.
Broccoli (1 spear has 232 RE of vitamin A) and other foods high in vitamin A or carotene will do the same, but you would have to eat almost 9 broccoli spears to equal the vitamin A in one carrot. Eat any raw vegetable that you like and try a greater variety. Vegetables higher in carbohydrate and calories like corn, peas, lima beans, winter squash aren't too tastey raw. Try including cauliflower, bell peppers, pea pods, cherry tomatoes and celery and lay off the carrots till the yellow cast to your skin fades. Take a stroll through the fresh vegetable section in your favorite gocery store to find what interests you. Be bold in trying vegetables you've never had like raw jicama.
Is pickled beet root the same thing as pickled beets in your part of the country? If so, they contain 0 vitamin A. Beets may darken your stool, but that is about it. But did you know that 1/2 cup of pickled beets contains 80 calories and 19 gms carbohydrate, mostly as sugar? Don't want to burst your routine if this satisfies your sweet tooth though.
To complete your journey, I would recommend you explore why you eat when stressed. Now that you have been successful at weight loss, do some work on your food behaviors. Don't just continue substituting a low calorie food for high calorie foods when you get stressed. This is difficult work to do poking around in your brain, but you can do it as your self confidence and self esteem is probably stronger now that you have tasted success.

I am a young student presently in the 9th grade. Your site is awesome! I am doing a project in biology class and I chose to do it on vitamin A. Your site was the only one that had some vital information on vitamin A. I was hoping that you could somehow give me some more information on vitamin A. It would be a tremendous help if you could give me some sites with some info on vitamin A. I live in Canada. Thanks for even considering this message.
Hey, thanks.
What is known about Vitamin A at this time is that there are animal sources (retinol) and vegetable sources (carotenes) in foods. Animal sources are about six times more potent than vegetable sources and can be toxic if taken in excess. Because of this, Vitamin A supplements are restricted to carotenes and under limited to under 25,000 IU per pill. One ounce of polar bear liver contains enough Vitamin A (retinol) to kill a person!
Your body uses Vitamin A for growth, healthy skin and cells (epithelial) that line any opening to the body (nose, throat, lungs, mouth, stomach, intestines, vagina and urinary tract) and good night vision. Absorption of vitamin A is dependent on fat from food sources and bile (cholesterol substance produced by your liver and stored by your gall bladder and used to break down fats, seeds and skins). Your body can store two year's worth of Vitamin A in your liver. If you don't eat enough Vitamin A, it can cause blindness or in milder cases, your ability to see or drive at night.
Good food sources are fish oil, liver (pork, lamb, chicken, turkey or beef), eggs, butter and orange or yellow vebetables or fruits. Broccoli is a good source of Vitamin A, but the cholorphyll (green) camoflages the yellow carotene color. If it weren't for chlorophyll, broccoli would be yellow or orange.
Some researchers have found that large amounts of Vitamin A can prevent the development of cancer in epithelial cells and yet other researchers have found the opposite is true. But, if you take large quantities of Vitamin A, your skin and even the whites of your eyes can turn yellow when your body stores for Vitamin A become saturated. If this happens, discontinue the vitamin A supplements and the yellow coloring in the whites of your eyes, palms of your hands and soles of your feet will go away in a few months. If the whites of a person's eyes are yellow and not caused by Vitamin A supplements, they could have liver disease like cirrhosis and should see their doctor immediately.
Hope this info helps your understanding of Vitamin A.
I am taking a vitamin supplement called carotene with 15 milligrams. The label says it can be converted to vitamin A, maximum 25,000 IU Also, I take Stresstabs. Is that too much?
Carotene is a pre-cursor form of retinol vitamin A that your body uses. It is not as toxic as retinol, but at 25,000 IU per day, that is excessive. It equals 4,166 RE of retinol vitamin A. Males (ages 11 to 51+) Recommended Dietary Allowances (RDA) for vitamin A is 1,000 RE and a females (ages 11 to 51+) RDA is 800 RE Why do you feel you need to take more than four times your RDA?
Your RDA of vitamin A could be achieved by eating two or three carrot sticks, one tablespoon of cooked carrots, two tablespoons of cooked winter squash, sweet potatoes or pumpkin, 1/4 cup of dark green leafy vegetables (spinach, beet greens or Swiss chard), 4 asparagus spears, 1/4 cup broccoli, one apricot, 1/2 peach or 1/4 cup cantaloupe. All of these are probably less expensive than your vitamin A pills.
Vitamin A is fat-soluble and is stored in your body along with vitamins D, E and vitamin K. Your body can store up to two years worth in your liver. Levels above 100,000 IU of vitamin A are considered toxic (hypervitaminosis). Loss of hair can occur with megadoses of vitamin A. Excess carotene can cause your skin and the whites of your eyes to turn yellow. I have seen a patient with a jaundice look to their skin and eyes because of excess carotene intake from supplements. Generally, carotene will turn the skin yellow when the intake is above 20 mg per day (about 34,000 IU). The yellow skin tint is most noticeable on the hands and soles of your feet where there is little underlying tissue between the skin and bones. If the carotene supplement is discontinued, the skin will lose the yellow tint.

Your body uses vitamin A for good night vision and for maintaining the health of your epithelial cells. These cells are found in skin as well as lining your respiratory tract and gastrointestinal tract. Research has found that persons who have an adequate intake of vitamin A have a lower incidence of epithelial cancers. Epithelial cells line the lungs as well as the gastrointestinal tract, urinary tract and vagina. Research has not advocated megadosing vitamin A to prevent cancer though. A new Finish research project showed that smokers increased their rate of cancer if they took Vitamin A supplements.
Stresstabs by Lederle are vitamin B complex, C, D and E pills. They do not contain vitamin A. Only your vitamin supplement contains A.
In the early 1980's the FDA restricted the vitamin A content of multivitamin supplements to a maximum of 1,000 RE to limit the possibility of vitamin A toxicity. You can buy vitamin A supplements up to 5,000 RE (25,000 IU).
I would suggest, you discontinue your vitamin A supplements and try eating bright orange or dark green leafy vegetables for vitamin A. Liver is also an excellent source.

Vitamin C - Titrating to Tolerance

The method of titrating a patient's dosage of ascorbic acid between the relief of most symptoms and bowel tolerance has been described. Either this titration method or large intravenous doses are absolutely necessary to obtain excellent results. Studies of lesser amounts are almost useless. The oral method cannot by its very nature be investigated by double blind studies because no placebo will mimic this bowel tolerance phenomenon. 

The method produces such spectacular effects in all patients capable of tolerating these doses, especially in the cases of acute self-limiting viral diseases, as to be undeniable. A placebo could not possibly work so reliably, even in infants and children, and have such a profound effect on critically ill patients. Belfield has had similar results in veterinary medicine curing distemper and kennel fever in dogs with intravenous ascorbate. Although dogs produce their own ascorbate, they do not produce enough to neutralize the toxicity of these diseases. This effect in animals could hardly be a placebo.

It would be possible to conduct a double blind study on intravenous ascorbate; however, doses would have to be determined by someone experienced with this method.
Part of the difficulty many have with understanding ascorbate is that claims for its benefits seem too many. Most of these clinical results merely indicate that large doses of ascorbate augment the healing abilities of the body already known to be dependent upon minimal doses of ascorbate.

I anticipate that other essential nutrients will be found being utilized at unsuspectedly rapid rates in disease states. Compli- cations caused by failures in systems dependent upon those nutrients will be found. The magnitude of supplimentations necessary to avert those complications will seem extraordinary by standards accepted today.

About Advanced Of Vitamin B

All vitamin B-Complex group are water soluble, and are linked together in several chemical ways. They are formed from either bacteria, yeast's, fungi, or moulds.

They are responsible for providing energy to the body during the conversion of glucose, from carbohydrates. They are also critically required for the metabolism of both fats and proteins, as well as the health and maintenance of the body's nervous system.

Vitamin B-1 Thiamine Necessary for proper metabolism of sugar and starch to provide energy. Maintains a healthy nervous system as well as aiding proper function of the heart and other muscles. Stress increases the need for B-1 and all B vitamins.

Found in Brewer's yeast, wheat germ, oatmeal, whole wheat, bran, whole brown rice, black strap molasses, soybeans, and meats.

Effective with B-Complex, B-2, Folic Acid, Niacin, Vitamin C, Vitamin E, Manganese.
Alcohol interferes with the absorption of this water based vitamin.

Vitamin B-2 Riboflavin Critical in the metabolism of carbohydrates, fats and proteins. Needed in the repair of the nails, skin and hair.

If you are looking to produce a higher level of energy in the body, Vitamin B2 is the one of the more important nutrients. If you exercise every day, you are using up your vitamin B2 supply.

Cheese and milk are the best dietary sources of this vitamin, also green vegetables and whole grains.
Vitamin B-3 Niacin Required for the synthesis of sex hormones, as well as being vital to the nervous system. It also aids circulation, and reduces serum cholesterol.

Because niacin dilates the blood vessels, many people taking this supplement regularly report the heat sensation and redness, commonly occurring in the area of the face.

The average daily dosage for adults is approximately 15 mg. Fish and chicken are good natural sources.
Vitamin B-6 Pyridoxine Involved in the metabolism of fats, especially the unsaturated fatty acids. Required by many amino acids for their metabolism, and also aids in the production of hydrochloric acid.

This vitamin must be present for the production of both red blood cells, and also antibodies. It plays an important role in the body's immune system B6 relieves a wide variety of PMS symptoms, such as breast tenderness, weight gain (water retention) and irritability. This very important vitamin has also been shown to be helpful in reducing or eliminating symptoms of nervous tremors and epileptic seizures.

Whole grains are a good source of this vitamin.

Vitamin B-12 Essential for the correct functioning of all cells, especially bone marrow and nervous tissue, it is also required for red blood cell formation.
Necessary for normal digestion, absorption of foods, proteins synthesis and carbohydrate and fat metabolism.
Found in liver, kidney, meats, fish, dairy products and eggs.

Biotin Required in the formation of glycogen, and is also essential in the making of fatty acids. Biotin, found as an ingredient in many of today's shampoos and hair conditioners, is said to repair damaged hair and keep hair healthy. Can be found in Brewer's yeast and nuts.

Choline Choline is an active factor in lecithin, and aids in the metabolism of fats. Helps lower cholesterol, transferring nerve impulse to the brain, helps against memory loss and senile dementia, aids the liver in removing poisons and drugs from the bloodstream.
Found in egg yolk, milk, meat, legumes and whole grains.

Pantothenic Acid Has an enhancing effect upon the adrenal glands, and is often taken during stressful conditions. It is also necessary during metabolism of fats, carbohydrates and proteins. Helps form certain hormones and antibodies.

Needed for maintenance of healthy digestive tract, skin, nerves and glands. Found in organ meats, brewer's yeast, egg yolk, whole grain cereal, chicken, bran, and nuts.
Folic acid Is active in the most basic life process that we know, the synthesis of the building blocks of life, DNA. People found to have various types of pre cancerous cells have also been found folic acid deficient. Other symptoms of too little folic acid are slowed metabolism, constipation, and tiredness at inappropriate times of the day.

Pregnant women are wise to ensure that intake of folic acid is adequately maintained, as it has been clinically proven to reduce birth defects, including Down's Syndrome.

People of all ages, from pregnant women to elderly men, are apparently deficient in the essential substance. Good sources to obtain the needed 400 to 600 mg. daily are broccoli and spinach.
Because the B complex group of vitamins work with each other, it is worth making sure that they are taken at the same time.

Vitamin and Mineral Supplements

AHA Scientific Position

We recommend that healthy people get adequate nutrients by eating a variety of foods in moderation, rather than by taking supplements. An exception for omega-3 fatty acid supplements is explained below.
The Recommended Dietary Allowances (RDAs) published by the National Research Council are the best available estimates of safe and adequate dietary intakes. Almost any nutrient can be potentially toxic if eaten in large quantities over a long time. Interactions between dietary supplements and prescription drugs and among several dietary supplements taken at the same time may occur. Too much iron can increase the risk of chronic disease, and too much vitamin A can cause birth defects.
There aren’t sufficient data to suggest that healthy people benefit by taking certain vitamin or mineral supplements in excess of the RDAs. While some observational studies have suggested that lower rates of cardiovascular disease and/or lower risk factor levels result in populations who use vitamin or mineral supplements, it isn’t clear if this is due to the supplements. For example, supplement users may be less overweight and more physically active.
Moreover, vitamin or mineral supplements aren’t a substitute for a balanced, nutritious diet that limits excess calories, saturated fat, trans fat and dietary cholesterol. This dietary approach has been shown to reduce coronary heart disease risk in both healthy people and those with coronary disease.

What about antioxidant vitamins?

Many people are interested in antioxidant vitamins (A, C and E). This is due to suggestions from large observational studies comparing healthy adults consuming large amounts of these vitamins with those who didn’t. However, these observations are subject to bias and don’t prove a cause-and-effect relationship. Scientific evidence does not suggest that consuming antioxidant vitamins can eliminate the need to reduce blood pressure, lower blood cholesterol or stop smoking cigarettes. Clinical trials are under way to find out whether increased vitamin antioxidant intake may have an overall benefit. However, a recent large, placebo-controlled, randomized study failed to show any benefit from vitamin E on heart disease.

What about omega-3 fatty acid supplements?

Epidemiologic and clinical trials have shown that omega-3 fatty acids reduce the risk of cardiovascular disease. Healthy people, people at high risk of CVD and patients with preexisting CVD all benefit. We recommend including omega-3 fatty acids in the diet mainly from fish and plant sources.
However, some people with high triglycerides (blood fats) and patients with CVD may benefit from more omega-3 fatty acids than they can easily get from diet alone. These people should talk to their doctor about taking supplements to reduce heart disease risk. (See the “Fish Oil and Omega-3 Fatty Acids” entry in this guide for more details

Vitamin Information Center

All living things, plant or animal, need vitamins for health, growth, and reproduction. Yet vitamins are not a source of calories and do not contribute significantly to body mass. The plant or animal uses vitamins as tools in processes that regulate chemical activities in the organism and that use basic food elements--carbohydrates, fats, and proteins--to form tissues and to produce energy.
Vitamins can be used over and over, and only tiny amounts are needed to replace those that are lost. Nevertheless, most vitamins are essential in the diet because the body does not produce enough of them or, in many cases, does not produce them at all.
Thirteen different vitamins have been identified by nutritionists: A, eight B-complex vitamins, C, D, E, and K. Some substances, such as carnitine and choline, behave like vitamins but are made in adequate amounts in the human body.
Vitamins were originally placed in categories based on their function in the body and were given letter names. Later, as their chemical structures were revealed, they were also given chemical names. Today, both naming conventions are used.

Dietary Supplement Fact Sheet: Selenium

 


What is selenium? Selenium is a trace mineral that is essential to good health but required only in small amounts. Selenium is incorporated into proteins to make selenoproteins, which are important antioxidant enzymes. The antioxidant properties of selenoproteins help prevent cellular damage from free radicals.  

Free radicals are natural by-products of oxygen metabolism that may contribute to the development of chronic diseases such as cancer and heart disease. Other selenoproteins help regulate thyroid function and play a role in the immune system.

What foods provide selenium? Plant foods are the major dietary sources of selenium in most countries throughout the world. The content of selenium in food depends on the selenium content of the soil where plants are grown or animals are raised. For example, researchers know that soils in the high plains of northern Nebraska and the Dakotas have very high levels of selenium. People living in those regions generally have the highest selenium intakes in the United States (U.S.).  

In the U.S., food distribution patterns across the country help prevent people living in low-selenium geographic areas from having low dietary selenium intakes. Soils in some parts of China and Russia have very low amounts of selenium. Selenium deficiency is often reported in those regions because most food in those areas is grown and eaten locally. Selenium also can be found in some meats and seafood.  

Animals that eat grains or plants that were grown in selenium-rich soil have higher levels of selenium in their muscle. In the U.S., meats and bread are common sources of dietary selenium. Some nuts are also sources of selenium. Selenium content of foods can vary. For example, Brazil nuts may contain as much as 544 micrograms of selenium per ounce. They also may contain far less selenium. It is wise to eat Brazil nuts only occasionally because of their unusually high intake of selenium. Selected food sources of selenium are provided in Table 1.

*DV = Daily Value.

DVs are reference numbers developed by the Food and Drug Administration (FDA) to help consumers determine if a food contains a lot or a little of a specific nutrient. 

The DV for selenium is 70 micrograms (ug). Most food labels do not list a food's selenium content. The percent DV (%DV) listed on the table indicates the percentage of the DV provided in one serving.  

A food providing 5% of the DV or less is a low source while a food that provides 10-19% of the DV is a good source. A food that provides 20% or more of the DV is high in that nutrient. It is important to remember that foods that provide lower percentages of the DV also contribute to a healthful diet. For foods not listed in this table, please refer to the U.S. Department of Agriculture's Nutrient Database.
