Free radicals are highly unstable and reactive molecules that are literally stealing electrons from your healthy cells at this very moment, causing damage that accumulates over time and contributes to ...

Free radicals are unstable molecules that can damage DNA, leading to diseases like cancer. Antioxidants from foods can neutralize free radicals and reduce their harmful effects. Oxidative stress ...

Free radicals have a terrible reputation. These reactive and unstable molecules have been associated with cancer, aging, and degenerative diseases such as Alzheimer's. Yet the body constantly produces ...

You may have heard that antioxidants are an important part of your diet – but what are they and what do they do? Generally, antioxidants balance out something called oxidants or free radicals, which ...

Researchers have discovered that free radicals generated at a specific site in non-neuronal brain cells called astrocytes, may promote dementia, according to a Weill Cornell Medicine study. Their ...

For the first time, researchers have been able to show how a cell closes the door to free radicals – small oxygen molecules that are sometimes needed, but that can also damage our cells. The study is ...

Oxidative stress is a direct consequence of an excess in the body of so-called free radicals—reactive, unstable molecules that contain oxygen. Free radicals are normal metabolic by-products and also ...

Our mitochondria are the main locus of free radical production and are therefore the primary sites of oxidative damage. As mitochondria become more damaged, they produce less energy and generate more ...

You may have heard about oxidative stress on social media. A TikTok search offers dozens of videos that claim to break down the complex chemical process and, in some instances, offer up “treatments” ...
