Enhancing autophagic activity, particularly through genetic upregulation of autophagy-related genes (e.g., Atg5) or chaperone-mediated autophagy receptors (LAMP2A), extends lifespan and mitigates age-related physiological decline in mammalian models.
While you cannot directly 'dose' autophagy like a supplement, the paper highlights that nutrient restriction (Caloric Restriction) and specific stressors (like exercise or low-dose stressors inducing hormesis) activate autophagy. The most actionable takeaway is that maintaining metabolic flexibility and avoiding chronic overnutrition supports the autophagic clearance mechanisms that decline with age.
The authors overexpressed Atg5 in mice and found an enhancement of the autophagy process and anti-aging features, compared with the wild type mice. The mean lifespan was also incremented... In aged mice, they generated a double transgenic mouse model, in which it was possible to modulate the expression of the lysosomal receptor for CMA. The results revealed that the enhancement of this receptor can prevent features of aging at cellular and organ levels.
Why this rating
Evidence is primarily from animal models (mice, yeast, flies) and cell lines; human data is limited to observational studies of centenarians.

- Caloric Restriction (CR) extends lifespan and mitigates aging biomarkers primarily by inhibiting mTORC1 signaling, thereby inducing autophagy, rather than solely through antioxidant effects.Good
- Decline in mitophagy and autophagy with age leads to the accumulation of damaged mitochondria and ROS, contributing to sarcopenia, neurodegeneration, and cardiovascular decline.Moderate
