Active B Complex™ provides a full-complement of essential B-complex vitamins in a high potency formula. Activated, coenzyme forms provide optimum B complex vitamin support for individuals who may have difficulty metabolizing standard supplemental forms of B vitamins, particularly those with the MTHFR gene mutation/variant. Inclusion of L-5-methyltetrahydrofolate (L-5-MTHF), a bioactive form of folate, ensures more immediate effects on metabolism than folic acid, the form of folate commonly used in fortified foods and supplements. Activated vitamin B12 (methylcobalamin) enhances B12 absorption and bioavailability. Benfotiamine, the lipid-soluble form of thiamine, is also included together with active forms of riboflavin and vitamin B6. Provided in small easy to swallow vegetarian capsules.
