B Activ contains the entire spectrum of B vitamins to support adrenal, neurological, and stress-related functions. It features activated forms of vitamins B2, B6, and B12; benfotiamine, a fat soluble, more physiologically active form of thiamin; and folate as Quatrefolic, which is proven to have greater stability, solubility, and bioavailability over calcium salt forms of 5-MTHF.
