Evidence Summary

The dramatic 'reverses aging hallmarks' headlines come from one very small trial at a single lab. A larger independent trial did NOT confirm the main result (it missed its primary glutathione endpoint). The evidence does not support the strong claims, though it may help a specific high-oxidative-stress subgroup.

Safety Considerations

Strong claims rest on one small single-lab trial that failed independent replication. NAC without glycine has been linked in animal studies to faster growth of pre-existing tumors (animal data only). Talk to a doctor if you have a cancer history.
