B6 Complex offers a comprehensive blend of B vitamins with high levels of vitamin B6 packed into one easy-to-take supplement. B vitamins support cellular, cardiovascular, neurological and cognitive health, while vitamin B6 is particularly supportive of nutrient metabolism and red blood cell formation. It is offered in this formula as both pyridoxine and the activated form pyridoxal-5-phosphate. Vitamin B12, which aids in energy metabolism and normal function of the immune system, is offered as a combination of methylcobalamin, adenosylcobalamin and hydroxocobalamin. Folate, provided as Metafolin® L-5-MTHF, the universally metabolized and biologically active form of folate, supports normal early development of the fetal brain and spinal cord, while biotin helps to maintain cognitive functions. B vitamins are also involved in methylation reactions alongside choline and inositol.
