Discover how antioxidants protect your body and keep you healthy!
What Are Antioxidants?
Antioxidants are special substances that protect our cells from damage! They work like tiny shields inside our bodies, defending our cells from harmful molecules called free radicals.
Think of antioxidants as your body's defense team! They come from the foods we eat, especially colorful fruits and vegetables. Different antioxidants have different jobs, but they all work together to keep your body healthy and strong.
Did You Know?
Your body produces some antioxidants naturally, but you get most of them from the foods you eat!

Found in citrus fruits, helps protect cells and heal wounds
Vitamin E

Beta-Carotene

How Antioxidants Work
Antioxidants work by neutralizing harmful molecules called free radicals. Free radicals are unstable molecules that can damage cells in your body. This damage is called oxidative stress.
Think of free radicals as tiny wrecking balls bouncing around inside your body. They're missing an electron, which makes them unstable. They try to steal electrons from your healthy cells, damaging them in the process. Antioxidants are like generous friends who donate their extra electrons to free radicals, making them stable and harmless!
