If you're looking for a folate supplement your body can actually use, this delivers 1,000 mcg of **Methylfolate** in the Quatrefolic form — the bioactive version that skips the conversion steps synthetic folic acid requires. That's well above the 400–800 mcg clinical range, giving you a full effective dose in a single tablet.
The Quatrefolic form matters more than the dose itself. Up to 40% of people carry MTHFR gene variants that impair folic acid conversion, making methylfolate the only reliable option for maintaining healthy folate levels. You're getting the premium form here, which is especially relevant if you're supporting methylation, prenatal health, or homocysteine management.
The one thing to note: at 1,700 mcg DFE, this exceeds the tolerable upper intake for synthetic folic acid. That threshold was set for folic acid specifically, not methylfolate, but if you're stacking this with a multivitamin that also contains folate, keep your total intake in mind.
