Rainbow Light began in 1981 by offering consumers a nutritious spirulina supplement and went on to become the first-ever food-based supplement brand. During nutritional content testing procedures in those early days, our researchers discovered that spirulina, when exposed to a light spectrophotometer, refracted all the colors of the rainbow.
In addition to their simple beauty, these rainbow colors revealed the full spectrum of nutritional constituents present in spirulina. Inspired by the power of nature revealed in this nourishing food base, our brand name was born! Since then, Rainbow Light has become a natural products leader and today, certified organic spirulina is still our primary food base. For 30 years, our targeted, food-based supplements have been delivering measurable health benefits and positive improvements in daily energy and vitality you can feel.
