Doctor's Best Fully Active B Complex provides B vitamin forms (”vitamers”) for absorption and optimal benefit. B vitamins are indispensable for making energy from foods, and for making and maintaining DNA, genes, cells, tissues, organs, and enzyme functions.

Supplementing with these B vitamins helps promote optimal health and well-being. Vitamin C is included for added stability. It is hypoallergenic, with no unhealthy colorants or additives.

This formulation contains only ORTHO nutrients, namely those vitamin forms (called “vitamers”) identical to those naturally built into the body’s chemistry, as first described by Nobel Prize winner Linus Pauling. ORTHO B vitamins are essential requirements for many enzymes, and without them these enzymes would be unable to function.

Benefits:
Supplies only the best-utilized B vitamin forms. Most B vitamin supplements use cheap forms that are not optimally utilized in the body. This formulation does not compromise—it provides generous amounts of the most active B vitamers.
Substitutes naturally fully active folate instead of synthetic folic acid. Folic acid is an artificial folate that is difficult for the body to assimilate. This formulation instead provides the body’s most fully active folate, MTHF (methyl-tetra-hydro-folate).
Provides sufficient, fully active vitamin B12. Very few supplements provide sufficient amounts of active vitamin B12. This formulation provides 1000 micrograms of fully active B12 to help ensure excellent oral absorption.

Take 1 capsule daily, with food, or more as recommended by a nutritionally informed physician.
