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 --
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.

Buy Vitamin B complex or MultiVit-Rx
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.
In order for the various vitamin B compounds to be utilized by the
body, they must first be converted into their active coenzyme forms. This
sublingual Coenzyme vitamin
B Complex goes directly into your bloodstream in its
active form, ready to go to work immediately.

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.
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
vitamin B12 and 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.
Mothers with low levels of vitamin B12 in their blood are at increased risk of having an infant with spina bifida -- a birth defect in which the spinal cord fails to form properly. Based on previous research, pregnancy guidelines recommend that women consume enough folic acid to reduce the risk of spina bifida and related problems. The new findings suggest that these guidelines should also include recommendations about vitamin B12.
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.

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.
Vitamin B research
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 ?
Passion Rx -- Sexual
Pleasure Pills formulated by Ray Sahelian, M.D.
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.
