Folic acid, also known as Folate, is a B vitamin which helps form building blocks of DNA, and building blocks of RNA, needed for protein synthesis in all cells. Therefore, rapidly growing tissues, such as that of a foetus, and rapidly regenerating cells, like red blood cells and immune cells, have a high need for folic acid. Folic acid deficiency results in a form of anaemia that responds quickly to folic acid supplementation.
In women's health, Folic Acid has become synonymous with conception and early pregnancy. In fact it's especially important in foetal development and governments worldwide recommend Folic Acid supplementation at 400mcg per day.
