The aging proteostasis decline: From nematode to human

Researchers reviewed studies from tiny roundworms called nematodes through humans. They examined proteostasis, the cell’s system for making, folding, repairing, and removing proteins. This system generally becomes less effective with age, allowing more damaged or misfolded proteins to build up. Studies in worms and other laboratory organisms found that strengthening these systems can sometimes extend life or improve health. Human research mainly shows age-related changes, not proof that a specific treatment can reverse them.

What this means for you: This helps explain aging biology but does not show that a supplement, diet, or product will restore protein management. You can ignore products making strong claims based only on this research.
