When it comes to vitamin supplements, most people think of plain white pills. But one company stood out thanks to the "rainbow effect" of spirulina—Rainbow Light.
This dietary supplement brand’s story proves that sometimes, a serendipitous discovery can create a legendary business.
Founded in 1981 in the beachside town of Santa Cruz, California, Rainbow Light began its journey in an era before the internet.
The brand’s name has a poetic origin:
Its early products included spirulina-based vitamins, which, under a spectrometer, refracted a full rainbow of colors.
Spirulina also contains a "rainbow" of nutrients, inspiring the name Rainbow Light.
Differentiation Strategy: Beyond Ordinary Vitamins
Unlike conventional supplements, Rainbow Light pioneered "whole-food-based" formulations, designed for optimal absorption and efficacy.
