 Twinlab's B-50 Caps


Twinlab's B-50 Caps provides a high potency combination of all of the B-Complex vitamins. The B-complex includes the essential water-soluble vitamins thiamine (vitamin B1), riboflavin (vitamin B2), niacin (vitamin B3), pantothenic acid (vitamin B5), pyridoxine (vitamin B6), biotin, folic acid and vitamin B12, as well as the nonessential vitamins choline, inositol and PABA. The combined actions of the B complex vitamins help support each vitamin's individual effects.

Each of the B complex vitamins is essential for many physiological functions in the body and is vital for optimum health. Vitamins B1, B2, B3, and B5 work together to support bodily functions that produce energy and form the fuel the body runs on - adenosine triphosphate (ATP). Vitamin B6 is required for the production and breakdown of amino acids. Vitamins B5 and B12, folic acid, choline and inositol are essential for the formation of all the cells in our body, as well as DNA (genetic material).

Certain diets, such as weight loss, vegetarian or very poor diets can increase the risk of B-complex dietary deficiencies. Other people at higher risk for B-complex deficiencies include the elderly, alcoholics, and people who can't absorb vitamins from foods. In particular, Vitamin B12 deficiency is one of the most common nutrient deficiencies. Vitamin B12 supplementation is often recommended for older adults, vegetarians and vegans.

Taking a daily B-complex such as Twinlab's B-50 Caps supplies the necessary nutrients to boost energy, promote healthy cells, support amino acid activity, prevent B-Complex deficiencies and maintain overall well-being.


A great advantage of Twinlab's B-50 Caps is it provides a convenient way to benefit from a high potency blend of all of the B-complex vitamins. Rather than purchasing each B vitamin separately, you'll get convenience and value with Twinlab's B-50 Caps.

Studies have found that Twinlab's B-50 Caps nutrients have numerous benefits including:

  • Enhances energy levels
  • Promotes healthy cells formation
  • Aids in DNA (genetic material) formation
  • Supports amino acid activity
  • Prevents B vitamins deficiencies
  • Lowers toxic homocysteine levels (high homocysteine levels increase the risk for chronic diseases including heart disease and dementia)


The recommended dosages for each B-complex vitamin are different, varying from 3 mcg to 18 mg each day. However, this supplement has equal amounts of the B-complex vitamins at 50 mg each (except for folic acid and biotin). Since the B-complex vitamins are water soluble, the vitamins not absorbed by the body are excreted. This can be a waste of your hard-earned money.

It's popularly believed that when an individual B vitamin is taken for a health problem, you need to take all of the B-complex vitamins to avoid an imbalance. However, there are no studies supporting this claim.

Furthermore, many multivitamin-mineral supplements include B-complex vitamins at their recommended dosages, along with the rest of the essential vitamins and minerals. A good quality multivitamin-mineral supplement that includes all of the B-complex vitamins may be a better investment for you.
