Thorne Basic B Complex - 60 Capsules | Thorne Cover the basics of wellness with a balanced complex of all eight B vitamins. 8 easily-absorbed B vitamins, plus Choline – packed into one capsule for a simple way to promote neurological function and cellular energy production. Thorne’s Basic B Complex formula contains the active forms of the B vitamins, making it easy for your body to absorb them. This comprehensive blend provides multiple benefits to support your lifestyle, such as helping convert food into fuel and enhancing cellular energy. Because most B vitamins don’t remain in the body, they must be acquired from diet and supplementation to help maintain optimal health. Supplementing with tissue-ready B vitamins is important for everyone, especially individuals who aren’t able to convert the non-active B vitamins to their active forms. Factors that can inhibit the body's ability to convert non-active vitamins to their active forms include genetic predisposition, compromised liver function, poorly functioning enzymes, digestive disturbances, and aging.
