Autophagy is the body's cellular recycling process, and certain compounds, including spermidine, urolithin A, resveratrol, and berberine, have been shown in research to enhance it. This guide ranks the most evidence-backed autophagy supplements, explains how each works at the cellular level, and covers dosages, safety, and whether supplements can trigger autophagy without fasting. It also explains what can interrupt autophagy and how supplements compare with fasting, exercise, and sleep.
