Supplements and targeted interventions aim to influence biological pathways associated with aging, stress resistance, and cellular repair. While some compounds show promise, longevity interventions require careful evaluation of evidence, dosage, timing, and long-term risk.
This hub explores supplements and non-pharmacological interventions that may support healthy aging, focusing on mechanisms, scientific evidence, and practical limitations.
Longevity Supplements: Core Concepts
Longevity supplements target aging-related pathways rather than short-term symptom relief.
