DHA ONE® with Folate is superior to other prenatal vitamins in that it is a once daily, small, easy-to-swallow softgel that provides nutrients essential to the well-being of you and your baby. The ultra-purified DHA in our product means that it is virtually free of the contaminants that may be found in fatty fish with no fishy aftertaste. On top of this, DHA ONE® with Folate incorporates a stool softener to help you avoid the constipation issues that can arise during pregnancy. We have intentionally kept calcium out of our formula, as calcium blocks the absorption of iron, an essential mineral for all pregnant women and their babies. We are also one of the few prescription prenatals that include biotin and iodine in our formula, an essential vitamin for tissue growth and brain development.
