The body uses hydrogen peroxide (H2O2) for many of its functions such as protein and carbohydrate metabolism, immunity functions; as well as fat and mineral metabolism. So this is to say that our bodies are not strangers to utilizing it. In fact, your immune cells release peroxides to help fight and kill most infections.
