What is Autophagy?
Autophagy is the cell's recycling process, in which it breaks down and clears away damaged proteins and worn-out components, then reuses the salvaged parts. The name means self-eating, and it is one of the ways cells keep themselves in working order.
Autophagy is a housekeeping process rather than an energy or growth pathway, and it overlaps with several ageing-related ideas. It is one route by which the body limits cellular senescence, it clears faulty mitochondria so healthier ones can take over, and it is influenced by nutrient-sensing pathways that also involve sirtuins.
The topic draws interest from people focused on longevity and metabolic health. The catch is that most of what we know comes from cells and animals, human autophagy is hard to measure directly, and no single supplement flips it on like a switch. The strongest triggers remain fasting, exercise and sleep, so a pill is at best a minor contributor.
If you want to support the NAD+ pathway that sits upstream of much cellular repair, our NMN targets that step.
Frequently asked questions
How is it different from general metabolism?
Metabolism is the broad set of reactions that build and burn fuel. Autophagy is the narrower clean-up arm that dismantles damaged parts so their building blocks can be reused.
Who uses it, or when is it the right choice?
People interested in ageing and metabolic health pay attention to autophagy, usually through fasting and exercise habits. It is a lifestyle-led process more than a supplement one.
When is it the WRONG choice?
Chasing autophagy through aggressive fasting can backfire for anyone with high training loads, a medical condition or disordered eating. It is also the wrong focus if you expect a supplement to deliver it on its own.
