Antioxidant enzymes

Sources:

Antioxidant enzymes play a critical role in our cells by removing free radicals, which are harmful byproducts of cellular metabolism that can cause oxidative stress and damage. Rhonda Patrick discusses how these enzymes, such as those incorporating selenium, help cope with biological stress. Specifically, our cells evolved mechanisms to incorporate potentially toxic elements like selenium into antioxidant enzymes, thereby neutralizing free radicals and aiding in stress resistance 1.
