What Are Oxidants?

National Jewish Health immunology researcher Brian Day, PhD explains what oxidants are and how they cause disease and inflammation.

Transcript

Oxidants are reactive molecules that are produced both inside your body and the environment that can react with other cellular molecules in your body such as protein, DNA and lipids.

When it does that, it damages molecules and it’s what causes disease and inflammation.

An antioxidant is a molecule, as the term suggests, that defends you against those oxidants.

It actually intercepts those oxidants so they can’t react with your cellular macromolecules, therefor protecting you.
