Overview

Rainbow Light Prenatal One is the original one-tablet-per-day prenatal vitamin that pioneered the food-based prenatal category. Each tablet provides 800mcg folic acid, 18mg iron, vitamin D3, and a comprehensive vitamin/mineral profile along with probiotics (25 million CFU Lactobacillus) and a digestive support blend with ginger to help with morning sickness. The 150-tablet count provides a 5-month supply — one of the longest-lasting prenatals available. Rainbow Light has been making natural supplements since 1981 and Prenatal One has been their flagship product for decades.

Our Verdict

8.2/10 — Very Good
