Folic acid→Folate (methylfolate)
The folate your body has to convert
Folic acid is a man-made chemical that doesn't exist in food. Before your body can use it, it has to convert it into folate — and a large share of people carry gene variants (you may have heard of MTHFR) that sharply reduce their ability to make that conversion. For them, unconverted folic acid can build up while the folate they actually need stays low.
It's in nearly every inexpensive multivitamin and plenty of fortified foods. Our formulas skip it entirely and use methylfolate — the active form, ready to use, no conversion required.
