Folic acid is one of the vitamin B. The body requires Folic Acid for the creation of red blood cells and other new cells. There is no folic acid in the food, but there are folates, which have several different types and they are absorbed from food in different amounts. Usually, only one-half to two thirds of folates from food can absorb.

If you buy supplements of folic acid in pharmacies on by own without a prescription prescribed need to know some facts. If folic acid supplements are used in small doses, generally do not show any adverse effects. These supplements, which may occur in the form of capsules, beside folic acid, usually contain some vitamins (B6, B12, Omega-3 acids, phytosterols).
