Why supplements aren't a shortcut to healthy ageing

Supplements are marketed as a shortcut to healthy ageing, but the evidence for most of them is thin.

Trials repeatedly find that vitamins and minerals help people who are genuinely deficient, and do little for those who are not.

Researchers point instead to the unglamorous basics: resistance exercise, sleep, protein intake and staying socially connected.

Some supplements also interact with prescription medication, which is worth checking before adding anything.
