Vitamin B Complex benefit, side effects, including thiamine, riboflavin and others by Ray Sahelian, M.D.
Feb 14 2014

Vitamin B supplements are the cheapest, safest, and most reliable way to improve your wellbeing and overall mental abilities. I recommend Vitamin B complex to those who wish to improve their mood, mental clarity, and energy. The effects of the vitamin B are subtle, especially in the young who normally have adequate dietary intake of these nutrients. Improvements in cognitive functions from vitamin B are particularly noticeable in middle age individuals and the elderly. These vitamins are mostly absorbed through the small intestine.

B 1 --  Thiamine  Cocarboxylase
B 2 --  Riboflavin  Flavin Mono Nucleotide
B 3 --  Niacin,  Nicotinamide, NADH
supplement
B 5 --  Pantothenic acid, Pantothene
B 6 --  Pyridoxine  Pyridoxal Phosphate
B12 -- Cyanocobalamin  Dibencozide or Methylcobalamin. The absorption of dietary vitamin B12 occurs in the small intestine and requires a secretion from the stomach known as intrinsic factor.

Adverse reactions, is it safe, any danger?
High dosages could induce anxiety, stimulation, and heart beat abnormalities.

Which vitamin form is more absorbable  /effective: capsule containing active forms of Vitamin B or a sustained released tablet containing the inactive forms? I am contemplating two products:1) Montiff B-Long (sustainted release): Tablet; Does not contain active forms of vitamin B. Thorne Research B-Basic: Capsule; Contains active forms.
   In the long run it is difficult to predict the outcome from either one. I prefer these not being used daily and it is a good idea to use products from different companies and alternate them rather than using the same ones all the time. Most often the amounts present in such capsules in a higher dosage than the body needs or requires.

Right now im looking for a 100% Vegetarian Coenzymated Sublingual B Complex Lozenge or Tab that dissolves in the mouth OTHER than the Source Naturals brand. The reason why i dont want to use the Source Naturals brand is because it contains Sorbitol. Can you please let me know if any other company provides a coenzymated sublingual vegetarian B complex Lozenge or Tab thats either sugar free or uses Xylitol or Stevia instead of Sorbitol?
   We have not looked to see what other company sells this. The amount of sorbitol is so small as to be insignificant in terms of health effect.

I purchased a product Vitamin-B-Coenzyme-Complex. I am having very good results. I have a doubt regarding the dosage. the product contains NADH-5mg / tablet. the dosage for NADH in the book mind boosters is to take 2.5-5mg of NADH only a few times a week. whereas the the bottle indicates to take 2-3 tablets daily (which is 10 / 15 per day).
   We believe 1 tablet of vitamin B coenzyme a few times a week is sufficient. However each person is different.

Vitamin B and mosquitoes
Is it true that vitamin B, taken orally, prevents mosquitoes from biting?

Testing vitamin B as a home remedy against mosquitoes.
J Am Mosq Control Assoc. 2005.
The results of a small number of published studies suggested that vitamin B complex supplements are not effective as repellents, but these studies were limited by the use of very few human subjects and only 1 species of mosquito, Aedes aegypti. We extended this work with the use of larger samples of human subjects and with Anopheles stephensi as the test organism. We tested whether ingestion of vitamin B supplements under various regimens affected the attractiveness of volatile skin components transferred to glass vials. Although there was substantial and consistent individual variation in attractiveness, we found no effect of vitamin B supplementation.

Vitamin B12 information
Deficiency may occur in patients with Crohn's disease.

Older men with low levels of vitamin B-12 are at increased risk for bone fractures, University of Gothenburg, news release, Dec. 12, 2013.

Acid-inhibiting drugs like Zantac and Prilosec have become hugely popular because they're so good at preventing the unpleasant symptoms of heartburn and acid indigestion. But the drugs also make it more likely that a person will be short on vitamin B-12. And that can contribute to health problems including depression, nerve damage and dementia. December 14, 2013

My question is on vitamin B12 and whether the different forms of taking it - orally, sublingually or by injection - result in different uptakes / absorption. In particular, does a vitamin B12 injection result in more immediate availability than an equivalent oral or sublingual dose? Incidentally, I notice that Harvard University are doing research on its effect on sleep / wake cycles although they are using the cyanocobalamin rather than the methylcobalamin form.
   Blood levels of vitamin B12 are influenced by the form of ingestion, whether orally or by injection. However, most of the time the dose of vitamin B12 that is given is so large, that practically speaking it is difficult to guess whether it makes much difference in overall health. Those who have a severe form of pernicious anemia or vitamin B12 deficiency are probably better off getting an injection.

Those who use proton pump inhibitors, such as Prilosec, for prolonged periods, particularly the elderly, may potentially have a deficiency.

The recommended daily intake for vitamin B-12 should be more than doubled from the current level.
In a study of 98 middle-aged and older women, researchers found that 6 micrograms of B-12 per day seemed to be enough to prevent signs of mild vitamin B12 deficiency. That compares with the current recommended dietary allowance (RDA) of 2.4 micrograms per day. Vitamin B-12 is essential for maintaining healthy nerve cells and red blood cells; a deficiency in the vitamin can cause symptoms ranging from the subtle -- including fatigue and mild dizziness -- to more severe complications like nerve damage, anemia and even dementia. Though the typical Western diet provides people with far more than the current RDA for B-12, certain individuals are at risk for a deficiency. Unlike most vitamins, B-12 occurs naturally only in animal products, including meat, poultry, fish and, in lesser amounts, eggs and dairy. So vegetarians and vegans -- who avoid all animal products, including dairy -- may have low stores of the vitamin. The same is true of adults older than 50, as many have a thinning in the stomach lining that prevents the proper release of digestive acids. Stomach acids are essential for "shaking loose" vitamin B-12 from its food source, allowing it to be absorbed. So older adults are advised to get their B-12 from pills and fortified foods like cereal. That RDA is what experts believe is the minimum B-12 needed to prevent anemia, nerve damage and mental dysfunction. But it's not clear that it's enough to prevent subtler effects. American Journal of Clinical Nutrition, January 2006.

Oral supplements of vitamin B12 appear to correct vitamin B12 deficiencies as well as B12 injections. However, the group of European researchers found that, in order to correct a deficiency, oral doses need to contain more than 200 times the recommended daily allowance (RDA) of vitamin B12. Study author Dr. Lisette C. P. G. M. de Groot of Wageningen University in the Netherlands explained that most people develop vitamin B12 deficiencies as a result of "malabsorption," in which their bodies become unable to extract vitamin B12 from food. The deficiency typically strikes older people, she added, and takes years to develop. In some instances, people who avoid animal products -- such as vegans and followers of a macrobiotic diet -- can also develop a deficiency in vitamin B12 as a result of not eating enough B12-rich foods. A vitamin B12 deficiency is typically treated by monthly, often painful, shots. To investigate whether an oral dose of vitamin B12 works, as well, they tested various daily doses of oral vitamin B12 supplements in 120 people aged 70 and older. They found that daily oral doses of 647 to 1032 micrograms of vitamin B12 appeared to correct the deficiency. The current RDA for vitamin B12 is 3 micrograms per day.

B6 toxicity and deficiency
Q. Do you have anything I can now read regarding the toxicity of Vitamin B6? I read an article by someone on the internet and it said an amount of 1000 times the RDA of Viamin B6 can be very toxic. My husband is taking 5000 times the RDA! So I called a nutrition physician to ask if this that I had read on the internet was true, and was assured the amount he was taking was perfectly safe. So we are very confused. I realize you cannot answer definitive questions re someone's health problem, but could you please tell us something we can read re the toxicity of Vitamin B6? Whatever my husband takes, the SAMe-, vitamin B6, etc. he will be probably be taking the rest of his life. He takes them for restless legs syndrome. He is not taking any prescription medication except a sleeping pill (Temazapam) which he uses nightly until it quits working, then off it a couple of nights, etc. Without the sleeping pill, he is lucky to get 2 hours a night; with it, maybe 4 hours. He is so very, very tired, you can see why we are trying to learn all we can. We are so appreciative of learning from your website about the possible side effects of SAM-e and also will be appreciative if you can help us learn about the toxicity of Vitamin B6.
   A. There have been reports of excess vitamin B6 causing neuropathy. 5000 times the RDA for vitamin B6 is quite a hefty dose.

How much vitamin B6 is toxic?
Ned Tijdschr Geneeskd. 2005. Katan MB. Wageningen Centre for Food Sciences en Wageningen Universiteit, afd. Humane Voeding, Bomenweg 2, 6703 HD Wageningen.
Vitamin B6 (pyridoxine) causes neuropathy at intakes of 1000 mg per day or more, which is about 800 times the daily intake from foods. There have also been occasional reports of toxicity at intakes of 100-300 mg per day. The US authorities set the no-observed-adverse-effect-level at 200 mg per day and the safe upper limit at 100 mg per day. A report of neurotoxicity in 2 patients who had taken 24 mg and 40 mg of vitamin B6 per day respectively, may be coincidence rather than a true toxic effect of such relatively low doses. However, physicians need to remain alert to high intakes of vitamin B6 as a cause of unexplained neuropathy.

Rosacea fulminans triggered by high-dose vitamins B6 and B12.
J Eur Acad Dermatol Venereol. 2001.
Rosacea fulminans is a rare variant of rosacea conglobata that occurs almost exclusively in women well past adolescence. The aetiology is unknown, although immunological, hormonal, and vascular factors have been suggested. We report the case of a 17-year-old girl with rosacea fulminans that was temporally associated with daily ingestion of high-dose vitamin B supplements.

Pak J Pharm Sci. 2013. Vitamin B6: deficiency diseases and methods of analysis. Vitamin B6 (pyridoxine) is closely associated with the functions of the nervous, immune and endocrine systems. It also participates in the metabolic processes of proteins, lipids and carbohydrates. Pyridoxine deficiency may result in neurological disorders including convulsions and epileptic encephalopathy and may lead to infant abnormalities. The Intravenous administration of pyridoxine to patients results in a dramatic cessation of seizures.

Vitamin B research
Effects of vitamin-B complex supplementation on periodontal wound healing.
J Periodontol. 2005.
Reports have demonstrated that nutrient supplements, in particular vitamin-B complex, can positively influence wound healing processes. However, limited information is available on the effects of vitamin b complex on periodontal wound healing. A total of 30 patients (13 males, 17 females) presenting with generalized moderate to severe chronic periodontitis were enrolled in this study. Vitamin B-complex supplement in combination with flap surgery resulted in statistically significant superior improvement compared to placebo.

Emails
Q. Interestingly, I took a vitamin B coenzyme complex you recommend on your site and I believe I feel a boost in energy, mental clarity, alertness & elevated mood. I went out to lunch w/ folks from the office and had quite a heavy meal: cheese burger w/ Louisiana sausage, some fries & a very heavy beer. I anticipated falling asleep at my desk after lunch, but I haven't really been dragging at all. This is great, I hope the effects continue! Thanks for your web site for encouraging me to start up with this stuff.

Q. I enjoy the vitamin B coenzyme complex so much, I am wondering if you carry it in a size larger than 60 count, as in, possibly 120 lozenges? I like your prices and found them to be cheaper than in a discount health food store, but they had the 120 count for $30 or so. I won't be ordering for another month and a half, but am curious. Your satisfied customer.
     A. At present Physician Formulas only have the 60 count vitamin B Co-Enzyme complex.

Q. I've just purchased some Sam-e for depression as I experience too many side-effects with anti-depressants. I have read that it is wise to take additional vitamin B s, particularly B6, B12 and folic acid, when taking Sam-e in order to prevent toxic build-up of homocysteine. Apparently these vitamins assist in the breakdown of homocysteine which is formed when Sam-e breaks down.
     A. We're not totally sure whether extra vitamin B is needed if someone is taking SAM-e. Perhaps it depends on one's diet and biochemistry. It would not hurt to take 1 to 3 times the RDA of vitamin B.

Q. Do you think testing for homocysteine blood level is important? Also, is there another form for Vitamin B 6 ?
     A. I'm not really sure homocysteine levels need to be checked since taking a vitamin B complex will lower them anyway. We do so many blood tests in this country, and medical expenses are skyrocketing. Why not just take a cheap  vitamin B complex? That' s my opinion, another doctor may disagree. Vitamin B6 is also found as pyridoxal5phosphate or P5P.Q. Are food based vitamins and minerals better than the synthetic kinds? It seams logical that food based supplements are healthier because they have co-factors that make them more natural and better absorbed, but I'm not sure if it's true. I was looking for a good B-complex for instance, and I can buy the New Chapter brand for$36 on-line, it has all the vitamin Bs that have been cultured in whole food, and one tablet contains about the daily value, same counts for Megafoods B complex. On the other hand I can buy coenzymated vitamin B complex for less money, but the problem with them is that some of the vitamin Bs are much higher than the other ones, for instance B1 and B6 are approx. 3000% (daily value) while the folic acid is only 100%, so I can't cut the pill in peaces because the golic acid is especially important to me. All the vitamin coenzymated B complex formulas seam to have that problem.
    A. As a general rule the food based supplements are probably a healthier way to take supplements especially since there is little reason in taking massive dosages of certain vitamins such as the high amounts found in vitamin B50 or B100 products. But each person is different and some may prefer the food based supplements whereas others notice more benefit from the higher dose coenzymated products. Either way it is a good idea to take breaks from them and not to take them every day.
