Antioxidants and free radicals — without the hype

Free radicals are unstable molecules produced in normal metabolism and in response to stressors like pollution and smoking. Antioxidants help keep that chemistry in balance. The marketing version of this story often oversells powders and miracles; the practical version starts with food patterns.

Food first

Colourful plants — berries, leafy greens, nuts, spices, cocoa, and a variety of vegetables — deliver antioxidant compounds alongside fibre and other nutrients. Diversity beats megadoses of a single isolated compound for most people.

Where supplements fit

Supplements can help fill gaps when diet or life stage makes intake harder — but they are not a licence to ignore vegetables. High-dose antioxidant supplements are not automatically safer; more can interfere with normal signalling or medication. Treat claims cautiously.

A calm takeaway

Think “colourful plate most days,” not “one hero molecule.” Pair that with sleep, movement, and not smoking — the unglamorous stack that actually compounds.
