Super Vitamin B Complex is an advanced and complete B-vitamin supplement. It provides substantial amounts of all eleven B-vitamins, including the co-enzyme forms of vitamins B2 and B6 for enhanced bioavailability, and extra pantothenic acid. Instead of using vitamins derived from allergen-containing plant sources such as yeast or corn, the B vitamins in this formula are synthesized from hydrocarbons, which originate ultimately from living sources, with very low allergy potential.
