Who all needs folic acid?

Everyone: Everyone needs it to produce health red blood cells, and for fertility our bodies need it to synthesize and repair dna. Its particularly important in infants and during pregnancy.

All women: Folic acid, AKA folate (folic acid) (vit B9), is recommended for all women wanting to get pregnant -- 0.4mg (400mcg) daily, which is important for preventing birth defects like spina bifida. Women w/ a hx these disorders should take 10x that amt daily -- 4mg (4000mcg) through the 3rd month of pregnancy. It won't affect fertility, chances of conception/twins, or periods. Can help with anemia.

No one : folic acid is synthetic - no one needs it. What you do need are natural folates found in raw fruit and vegetables, or methyl folate as a supplement.
