Bluebonnet B-Complex 100 Vcaps contain the full spectrum of pure, high potency B vitamins in easy-to-swallow vegetable capsules for maximum assimilation and absorption. Bluebonnet B-Complex 100 Vcaps provide all the water-soluble B vitamins, which play important roles in cellular metabolism. The B vitamins were once thought to be a single vitamin, referred to as vitamin B. Research later showed that they are individual vitamins that often coexist in the same foods. Supplements containing all eight B vitamins (thiamin, riboflavin, niacin, pyridoxine, cobalamin, biotin, folate, pantothenic acid) are referred to as a vitamin B complex. Bluebonnet B-Complex 100 contains 100 mg or 100 mcg of these essential B vitamins plus 400 mcg of folic acid. Essential to virtually every aspect of life, B vitamins are involved in many of the body's chemical and biological functions. B vitamins are crucial for energy production, nervous system health, and healthy hair, skin and nails.*
