Age reversal is the idea of making the body, or some of its cells, biologically younger, not just slowing aging down. Claims are usually based on a lower score on an aging clock, or on results in cells and animals. Very little has been tested in people so far. See our age reversal guide for what has been tried and how far each idea has got.
