B-Complex with Metafolin L-5-MTHF is a comprehensive B supplement providing essential B vitamins and Metafolin.

B-Complex with Metafolin L-5-MTHF

B-Complex with Metafolin by Douglas Laboratories, offers a comprehensive blend of B vitamins including pyridoxal-5-phosphate, riboflavin-5-phosphate and folate as 5-methyltetrahydrofolate (5-MTHF), the universally metabolized and biologically active form of folate designed to support cellular, cardiovascular, neurological and psychological health.


As co-enzymes, the B vitamins are essential components in most major metabolic reactions. They play an important role in energy production, including the metabolism of lipids, carbohydrates, and proteins. B vitamins are also important for blood cells, hormones, and nervous system function.

As water-soluble substances, B vitamins are not generally stored in the body in any appreciable amounts (with the exception of vitamin B-12). Therefore, the body needs an adequate supply of B vitamins on a daily basis.
Thiamin, riboflavin, and niacin are all essential coenzymes in energy production.


B-Complex with Metafolin may be useful for individuals who want to supplement with a complete array of B vitamins and related nutrients.
