No summary available for this substance.

Free Radicals

Free radicals are atoms, molecules, or ions with unpaired electrons, which make them highly reactive with other cellular components like DNA, protein, and lipids. They are produced in the body through normal cellular processes but can also be introduced from the environment. While they play several important roles, such as in cell signaling, excessive levels of free radicals can lead to oxidative stress, contributing to cell damage and various diseases.

“Ferrous iron leads to the production of free radicals that damage tissues in the body and, even worse, it leads to the accumulation of these zombie cells which we call senescent cells, and those drive the aging process, in part, large part, because they leach these inflammatory molecules that cause other cells in the vicinity to become inflamed, to age, to senesce and even cause cancer.”
