“Folate, also known as vitamin B₉ and folacin, is one of the B vitamins. Manufactured folic acid, which is converted into folate by the body, is used as a dietary supplement and in food fortification as it is more stable during processing and storage.“ wikipedia
“Folic acid consumed as a supplement separate from food is most highly bioavailable. The bioavailability of folic acid taken with a meal or as a food fortificant is approximately 85% compared with folic acid consumed while fasting.”(1)
