Rainbow Research was founded in 1976. The company’s philosophy is simple - use the best natural ingredients available, avoid unnecessary chemicals, and tell the truth. Since the beginning, Rainbow has chosen not to test its products on animals. Rainbow products are made in small batches to keep quality high. We guarantee our products 100%. Rainbow Research’s following has grown through the years and it now sells its products to health food stores, massage therapists, chiropractors, medical doctors, salons, and consumers throughout the world.
