Our approach
Longevity is a field where preliminary science can quickly become a marketing promise. We distinguish research on mechanisms or individual ingredients from evidence on finished products, identify uncertainty, and avoid treating supplements as disease treatments.
Important: Longevity Ledger provides educational information, not medical advice. If you take medication, have a medical condition, are pregnant or nursing, or are considering a new supplement, speak with an appropriate healthcare professional.
