"One-a-day prenatal with gentle formula that won't upset your stomach"
Rainbow Light Prenatal One is the go-to prenatal for women who struggle with nausea. The ginger and probiotic additions are thoughtful, and the one-tablet simplicity is appreciated during pregnancy. Just add a separate DHA supplement, as this formula doesn't include omega-3s.
