Your body needs folate for DNA synthesis, cell division, and healthy methylation — and this delivers it in the most usable form. **Methylfolate** ((6S)-5-MTHF, Quatrefolic) at 680mcg DFE bypasses the multi-step conversion that synthetic folic acid requires, which matters especially if you have MTHFR gene variants that slow that conversion.
The 680mcg DFE dose (equivalent to 400mcg of methylfolate) sits right in the clinical range of 400–800mcg. It covers the RDA of 400mcg and gives you meaningful support for energy metabolism and prenatal health. The Quatrefolic branded form is one of the most bioavailable methylfolate sources available.
If you're looking for higher-dose folate support — for example during pregnancy planning, where 800mcg+ is often recommended — you'd need to double up on capsules or choose a higher-strength product. For general daily folate needs, this dose is well-matched.
