What Is Autophagy? The Science Behind Cellular Cleanup

Autophagy is the body’s cellular cleanup process, helping cells break down and recycle damaged components to maintain function over time. In this video, we explain what autophagy is, how it works, and why it matters in the context of aging, metabolism, healthspan, and healthy aging. Full article: https://longevityinsights.co.uk/what-is-autophagy/ In longevity science, autophagy is considered an important maintenance mechanism because it supports cellular quality control and may help the body respond to stress more efficiently. Researchers study autophagy in relation to aging, inflammation, metabolic health, mitochondrial function, and biomarkers of biological aging. Understanding autophagy may help explain how cellular repair and recycling processes influence long-term resilience, tissue function, and overall healthspan.
