All HUM supplements are third-party tested for quality standards to ensure potency and purity. In fact, 100% of our supplements are Clean Label Certified, meaning they pass third-party tests for contaminants such as heavy metals, plasticizers, and pesticides.
In addition, our manufacturers are independently certified to comply with Good Manufacturing Practices (GMP). GMP means our manufacturers run additional third-party ingredient testing to ensure that each product has the right identity, purity, strength, composition, and limited contaminants.
