B Complex with Metafolin® is a comprehensive B supplement providing essential B vitamins and intrinsic factor, a nutrient necessary for optimal vitamin B12 absorption.
Douglas Laboratories® B-Complex is unique, including Metafolin®, Methylcobalamin Vitamin B12, and Intrinsic Factor in its formulation. Metafolin® contains only the S isomer of 5_MTHF and has been shown to be the only form of folate to be able to cross the blood-brain barrier. Studies indicate that methylcobalamin, a coenzyme form of B12, may be better utilized and better retained in the body. Intrinsic factor is a protein produced by cells in the stomach lining and is needed for the intestines to absorb vitamin B12 efficiently.
Adults take 1 capsule, one to two times daily or as directed by a healthcare professional.
