Overview

Life Extension Optimized Folate provides 1700mcg DFE of 5-methyltetrahydrofolate (5-MTHF), the bioactive form of folate that bypasses the MTHFR enzyme entirely. An estimated 40-60% of the population carries MTHFR gene variants that reduce the ability to convert folic acid to its active form. This supplement provides the end-product directly, ensuring adequate folate status regardless of genetic variation. The 100-tablet count provides over 3 months of daily supplementation.
