Folic Acid 400mcg tablets are an essential B-vitamin supplement that plays a crucial role in various bodily functions. This supplement is particularly important for women planning pregnancy or in early pregnancy stages, as it supports proper fetal development and neural tube formation. Folic acid is vital for cell growth and DNA synthesis. It helps in the formation of red blood cells and supports the normal function of the immune system. For pregnant women, it's recommended to take folic acid supplements from before conception through the first 12 weeks of pregnancy to help prevent neural tube defects. The 250-tablet bottle provides a long-term supply of this important nutrient.
