Rainbow Light has been committed to natural, whole-food-based nutrition since 1981, pioneering the concept of food-based vitamins that are gentle on sensitive stomachs. Their multivitamins are crafted with a whole-food and enzyme blend that aids digestion and absorption, making them one of the few multivitamins people can take on an empty stomach without nausea. Rainbow Light was an early adopter of Non-GMO Project Verification and uses only non-GMO ingredients in all formulas. Their Women's One, Men's One, Prenatal One, and Just Once product lines have earned decades of loyalty for delivering clean, comprehensive nutrition in just one daily tablet — making consistent supplementation as simple as possible.
