Learn all about Vitamin B ComplexShare ThisB-Complex VitaminTop Selling Vitamin B Complex Supplement$6.95 for 100 Capsules
The vitamin B-complex refers to all of the known essential water-soluble vitamins except for . These include
(vitamin B1),
(vitamin B2),
(vitamin B3),
(vitamin B5), pyridoxine (), , and the cobalamins ().
"Vitamin B" was once thought to be a single nutrient that existed in extracts of rice, liver, or yeast. Researchers later discovered these extracts contained several vitamins, which were given distinguishing numbers. Unfortunately, this has led to an erroneous belief among non-scientists that these vitamins have a special relationship to each other. Further adding to confusion has been the "unofficial" designation of other substances as members of the B-complex, such as choline, inositol, and para-aminobenzoic acid (PABA), even though they are not essential vitamins.
Each member of the B-complex has a unique structure and performs unique functions in the human body. Vitamins B1, B2, B3, and biotin participate in different aspects of energy production, vitamin B6 is essential for amino acid metabolism, and vitamin B12 and folic acid facilitate steps required for cell division. Each of these vitamins has many additional functions. However, contrary to popular belief, no functions require all B-complex vitamins simultaneously.
Human requirements for members of the B-complex vary considerably from 3 mcg per day for vitamin B12 to 18 mg per day for vitamin B3 in adult males, for example. Therefore, taking equal amounts of each one as provided in many B-complex supplements makes little sense. Furthermore, there is little evidence supporting the use of megadoses of B-complex vitamins to combat everyday stress, boost energy, or control food cravings, unless a person has a deficiency of one or more of them. Again, contrary to popular belief, there is no evidence indicating people should take all B vitamins to avoid an imbalance when one or more individual B vitamin is taken for a specific health condition.
products contain the B-complex along with the rest of the essential vitamins and minerals. Since they are more complete than B-complex vitamins alone, multiple vitamin-mineral supplements are recommended to improve overall micronutrient intake and prevent deficiencies.
Reliable and relatively consistent scientific data showing a substantial health benefit.Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support.
Our proprietary Star-Rating system was developed to help you easily understand the amount of scientific support behind each supplement in relation to a specific health condition. While there is no way to predict whether a vitamin, mineral, or herb will successfully treat or prevent associated health conditions,
our unique ratings tell you how well these supplements are understood by the medical community, and whether studies have found them to be effective for other people.
For over a decade, our team has combed through thousands of research articles published in reputable journals. To help you make educated decisions, and to better understand controversial or confusing supplements, our medical experts have digested the science into these three easy-to-follow ratings. We hope this provides you with a helpful resource to make informed decisions towards your health and well-being.
