A unified index of third-party supplement certifications — covering creatine, fish oil, magnesium, and vitamin D
— plus pet supplements via NASC.
Certification status is aggregated from each certifying body's own public listings. We report factual
certification status only — this is not medical or efficacy advice. Always verify
current status with the certifying body before relying on it. See our methodology.
