Testing & Certifications Explained

Rainbow Light is GMP Certified, meaning their manufacturing processes adhere to Good Manufacturing Practices as verified by a certifying body. However, there is no readily available evidence that Rainbow Light products undergo third-party testing for ingredient purity and potency. This means an independent lab does not verify the label claims.
