"Vitamin B" was once thought to be a single nutrient . Researchers later discovered these extracts contained several vitamins, which were given distinguishing numbers, leading many people to the erroneous conclusion that these vitamins have a special relationship to each other. Further adding to confusion has been the "unofficial" designation of other, non-essential vitamins, as members of the B-complex, such as choline, inositol, and para-aminobenzoic acid (PABA).
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, though none that require all B-complex vitamins simultaneously. Human requirements for each B vitamin vary considerably—from 3 mcg per day for vitamin B12 to 18 mg per day for vitamin B3 in adult males, for example. So, taking equal amounts of each one—as provided in many B-complex supplements—makes little sense. Megadoses of B-complex vitamins sometimes taken to combat everyday stress, boost energy, or control food cravings, do not appear to offer benefit unless a person is deficient in one or more of them.
Most multivitamin-mineral 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.
This supplement has been used in connection with the following health conditions:

Thiamine (vitamin B1), pantothenic acid (vitamin B5), and other B vitamins have all been shown to play a role in wound healing. For this reason, some healthcare practitioners recommend a high-potency B vitamin supplement to promote wound healing.
B-complex vitamins are needed to produce energy from carbohydrates. Exercisers may have slightly increased requirements for some of the B vitamins, including vitamins B2, B6, and B5, athletic performance can suffer if these slightly increased needs are not met.
People with achlorhydria (no stomach acid) or hypochlorhydria may not metabolize B vitamins properly, putting them at risk of developing various nutritional deficiencies, which could presumably contribute to the development of a wide range of health problems.
