Purity, Safety, and Quality

Rainbow Light's rigorous standards and processes ensure careful selection of suppliers, purity testing of all inbound materials, and product testing through every stage of manufacture including finished goods testing.

To begin, every formula is thoroughly reviewed by Rainbow Light's product development team, which includes a board-registered dietitian, a certified nutritionist and a fourth-generation herbalist with a Ph.D. in integrative biology and 30 years of clinical experience. The team combines the latest research with proven herbal wisdom and nutritional science to develop products that deliver meaningful health benefits.

Then, all incoming raw materials have certificates of purity and identity and Rainbow Light scientists test these materials with state-of-the-art technology to ensure they are free of microbiological contaminants, pesticides, herbicides and heavy metals. Rainbow Light is committed to providing you with natural supplements that are safe, pure and effective. We comply with all labeling regulations and our products are regularly tested to ensure that the potencies and ingredients shown on the label are accurate. Rainbow Light products also contain no artificial or objectionable additives. All Rainbow Light products are vegetarian, except for animal-derived ingredients present in certain products and clearly noted on the label. And, for those with specific sensitivities and preferences, we offer products clearly marked as Certified Organic (by Quality Assurance International), Allergen SafeGuard, VeganGuard, and SafeGuard.

As part of Rainbow Light's 31 year heritage, they have also been on the forefront of legislation pertaining to dietary supplements. Rainbow Light is a longstanding member of leading trade organizations for the natural products industry, such as the Council for Responsible Nutrition, the American Dietetic Association, the Non-GMO Project, the American Herbal Products Association, the American Herbalists Guild, the Natural Products Association, the American Botanical Council, and the Sustainable Packaging Coalition. These organizations have played key roles in the development and passage of the Dietary Supplement and Health Education Act (DSHEA) in 1994. DSHEA defined "dietary supplement," and set standards for ingredient and nutrition labeling, permissible claims, and established a safety standard, the basis for supplement Good Manufacturing Practices.
