Douglas Laboratories® B Complex with Metafolin® and Intrinsic Factor – 60 Capsules

B Complex with Metafolin®, manufactured by Douglas Laboratories, is a comprehensive B vitamin supplement that provides essential B vitamins and intrinsic factor, which is a nutrient necessary for optimal vitamin B12 absorption. What makes B Complex with Metafolin® unique from other B complex vitamins is it contains Metafolin®, a patented, natural form of (6S) 5-methyltetrahydrofolate (5-MTHF).

Vitamin B
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.

Metafolin® is a patented, natural form of (6S) 5-methyltetrahydrofolate (5-MTHF). 5-MTHF is the naturally occurring, predominant form of folate commonly found in cells and is essential for overall health, as it participates as a cofactor in a reaction that involves the remethylation of homocysteine to methionine. Unlike synthetic folic acid, 5-MTHF can be used directly by the body, without the need for an additional conversion via the enzyme (5,10-methylenetetrahydrofolate reductase (MTHFR)). In certain populations, the body’s ability to convert folic acid to 5-MTHF by use of this enzyme may be compromised due to genetic differences.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.

Intrinsic Factor
Intrinsic factor is a protein produced by cells in the stomach lining. It is needed by the intestines to absorb vitamin B12 efficiently. A deficiency of intrinsic factor can lead to vitamin B12 deficiency. Certain populations, including the elderly and those unable to effectively produce intrinsic factor, can be more susceptible to B12 deficiency.
