# How to Spot Longevity Pseudoscience

Longevity pseudoscience borrows the look of science, the studies, the mechanisms, the clinical words, without the evidence that makes it trustworthy. The fix is not cynicism. Sort claims by how strong the evidence is: lock in sleep, movement and food first (the fittest adults carry roughly 80% lower mortality risk), then add the supplements that have actually earned a place.

A field full of real breakthroughs and expensive nonsense. Here is how to tell them apart, and where supplements actually fit.
