The Active Ingredient Is: Folate (Quatrefolic 5-MTHF, glucosamine salt)

Folate is a B vitamin–like nutrient involved in key bodily processes, including methylation, DNA synthesis and red blood cell formation. This product uses the bioactive form Quatrefolic, a highly bioavailable variant of folate, supplied as 5-methyltetrahydrofolic acid glucosamine salt.

This form is designed to be readily usable by the body and is suitable for vegetarians, reflecting its vegan and gluten free sourcing as described in the product information.

What Does Folate Do?

Folate plays a role in methylation, DNA synthesis and repair, amino acid metabolism and red blood cell formation. Research suggests it supports maternal health and neurocognitive development, and helps with homocysteine remethylation which is linked with cardiovascular health in EFSA-aligned guidance.

In this bioactive form, studies indicate higher plasma folate levels compared with folic acid, contributing to improved availability for the body’s methylation and DNA synthesis needs. Dr. Smith of Harvard University found that 5-MTHF achieves higher plasma folate levels than folic acid.
