If you're looking for a folate supplement that your body can actually use without conversion, this delivers. You're getting 1,000 mcg of **Methylfolate** (as Quatrefolic), the bioactive form of vitamin B9 — well above the 400–800 mcg clinical range. Unlike synthetic folic acid, which requires multiple conversion steps to become active, this form bypasses those steps entirely, which matters especially if you carry MTHFR gene variants that impair conversion.
The dose here is generous. At 1,700 mcg DFE per tablet, you're covered for pregnancy support, methylation, and DNA synthesis without needing to stack additional folate sources.
One thing to keep in mind: high-dose folate can mask a **Vitamin B-12** deficiency by correcting anemia symptoms while neurological damage continues silently. If you're not already supplementing B-12, it's worth monitoring your levels alongside this product.
