Fully Active Folate 800 with Quatrefolic, 800mcg – 60 vcaps

Doctor’s Best Fully Active Folate 800 delivers 800mcg of folate per vegetarian capsule, using Quatrefolic® — a patented form of (6S)-5-methyltetrahydrofolic acid (MTHF) supplied as a glucosamine salt. Unlike standard folic acid, MTHF is the metabolically active form of folate, meaning the body can put it to work directly without requiring conversion. Each capsule provides 400% of the Nutrient Reference Value for folate.

Folate is an essential B-vitamin that the body cannot produce itself and must source from food or supplementation. MTHF plays a central role in methylation — a fundamental biochemical process involving the transfer of methyl groups across a wide range of metabolic pathways, including DNA regulation and cell function.

This 60-veggie-capsule pack from Doctor’s Best, a brand known for its science-led formulations and quality manufacturing standards, is well suited to those following a plant-based diet, individuals with genetic variations affecting folate metabolism, and anyone looking to maintain adequate folate intake through a straightforward daily capsule.
