Folate is needed to form healthy blood cells, specifically red blood cells. It is an essential prenatal supplement for pre-conception and throughout pregnancy as it supports baby's brain, eye, and nervous system development. Folate is also a key nutrient for your skin, cartilage, teeth, and bone health.
