Fully Active Folate 400 with Quatrefolic, 400mcg – 90 vcaps

Doctor’s Best Fully Active Folate 400 delivers folate in the form of Quatrefolic — a patented, stabilised form of (6S)-5-Methyltetrahydrofolic acid, glucosamine salt. Unlike standard folic acid, which the body must convert through several enzymatic steps, Quatrefolic provides folate in a biologically active form that is directly usable. Each vegetarian capsule delivers 400 mcg DFE of folate, meeting 200% of the established nutritional reference value.

Folate contributes to normal blood formation and contributes to normal psychological function. It also contributes to the reduction of tiredness and fatigue. Each capsule also provides 40 mg of Vitamin C in the form of ascorbic acid, which contributes to the protection of cells from oxidative stress, contributes to normal function of the immune system, and contributes to the reduction of tiredness and fatigue.

Produced in the United States, this formula is free from GMOs, gluten, dairy, and animal-derived ingredients, making it suitable for vegans and vegetarians. The clean ingredient profile — with no added sugars, sweeteners, starch, salt, or preservatives — reflects Doctor’s Best commitment to straightforward, science-based supplementation.
