Active B Complex

A combination of B vitamins in their most active form. Includes the most body-compatible active forms of vitamins B6 and B12, riboflavin, and folate. Supports energy-yielding metabolism and tissue formation. Promotes red blood cell formation. Contributes to the normal function of the immune system. Helps prevent deficiencies in thiamine, riboflavin, niacin, vitamin B6, folate, vitamin B12, biotin, and pantothenic acid. Each full-dose capsule of Active B Complex provides adults with the Recommended Dietary Allowance (RDA) for the full range of B vitamins, including thiamine, riboflavin, niacin, pantothenic acid, vitamin B6, biotin, folate, and vitamin B12. Active B Complex uses the active form of vitamins B2 (riboflavin-5-phosphate), B6 ​​(pyridoxal-5-phosphate), folate (Metafolin®), and B12 (methylcobalamin) that is more easily absorbed by the body. Metafolin® is a calcium salt of L-methylfolate, the primarily active form of folate in the body. Compared to folic acid, L-methylfolate has significantly higher bioavailability. For example, in healthy women supplemented with an equivalent amount (~400 mcg) of L-methylfolate or folic acid for 24 weeks, red blood cell folate concentrations were found to be significantly higher in the women supplemented with L-methylfolate.
