Oxidative stress, explained: why a brilliant system falls behind.

Every time you breathe, you rust, just a little. It's the quiet cost of being alive. The same oxygen that powers your cells also throws off reactive by-products called free radicals, and your body has been handling them, brilliantly, since the day you were born.

A system built to defend itself

Your cells don't wait for help from the outside. They make their own defense. A network of enzymes, superoxide dismutase, catalase, glutathione peroxidase, neutralises free radicals almost as fast as they appear, holding the whole system in balance. This is your endogenous antioxidant defense: endogenous meaning made within. It is faster, more precise, and more capable than anything you can swallow.

For most of your life, the count stays even. Free radicals are produced; your defenses clear them; balance holds.

Why the balance tips

Modern life asks more of that system than it was ever designed for. Pollution, ultraviolet light, ultra-processed food, broken sleep, relentless stress, each adds to the oxidative load. At the same time, the body's own output of its defense enzymes gradually eases with age. The result isn't failure. It's arithmetic. A little more on one side of the ledger, a little less on the other, and slowly the count starts to run behind. Scientists call that gap oxidative stress.

Aging is not a disease, and your body is not broken. A capable, self-restoring system is simply being outpaced by the pace of modern living.

The opportunity

If the real issue is that your own defenses are running behind, then the interesting question isn't which antioxidant to add from the outside. It's whether you can help your body make more of its own. That difference sits at the centre of everything we do, and it's the subject of the rest of this Journal. ^*
