L-5-MTHF Capsules by Seeking Health provides 1,700 mcg DFE (1,000 mcg) of pure non-racemic L-methylfolate, an active coenzyme form of folate.
Folate is a water-soluble B vitamin that occurs naturally in food, such as leafy green vegetables, citrus fruits, dried beans, and peas. The methylated form, L-5-methylfolate (L-5-MTHF) requires no additional metabolic steps to be used by the body and is often the preferred choice for those with absorption or metabolic defects. L-5-MTHF efficiently supports methylation, DNA biosynthesis, homocysteine metabolism, and nervous system function. L-5-MTHF is easily absorbed and used by cells. It is the predominant folate in circulation and the only form of folate that can cross the blood-brain barrier.
