What Are Antioxidants
Simple definition
Antioxidants are molecules that neutralize free radicals, unstable atoms that chase after electrons and can damage cells, DNA, and proteins. Think of free radicals as tiny rust spots forming on metal; antioxidants act like the protective paint that stops the rust from spreading.
How they protect you
When free radicals pile up, they trigger inflammation, agerelated decline, and raise the risk for chronic illnesses like heart disease and diabetes. By donating an electron, antioxidants stabilize these radicals and prevent them from wreaking havoc. Studies from the show a clear link between highantioxidant diets and lower markers of inflammation.
Are more always better?
Surprisingly, yes and no. While a diet rich in natural antioxidants is a win, megadoses of supplements can sometimes act as prooxidantsessentially flipping the script and creating more free radicals. Its a classic case of too much of a good thing. A 2023 review in warns that excessive vitaminE or C may interfere with muscle recovery and certain medications.
Expert tip
Ask a registered dietitian to help you balance food sources with any supplement you consider, especially if youre on medication or have a health condition.
