Peroxynitrite Scavenger PM (Free Radical X P.M.) is designed to help clear the body of the dangerous free radical, peroxynitrite. Peroxynitrite is considered to be one of the major pathological causes of numerous diseases in that it suppresses mitochondrial function and triggers cell death via oxidation and nitration reactions. Poor diets, environmental toxins and genetic variants can all lead to an increase in peroxynitrites and glutamate, lowered antioxidants and slower rebuilding and repair of cells, which causes faster aging and conditions for disease. This product can be used for those genetically at risk for high levels of inflammation and/or those with signs and symptoms of inflammation. This product also contains nutrients such as melatonin that help support sleep.
