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