Study finds salivary 8-OHdG is associated with increased severity of ED in men. The study found that phosphodiesterase 5 inhibitor therapy increased total and free Testosterone as well as decreased 8-OHdG.
Selenium (Se) deficiency is associated with increased oxidative stress. Selenium is a cofactor necessary for glutathione perioxidase. Selenium reduced 8-OHdG, promoted cell growth inhibition and cell death pointing to significant Cancer implications.
Mouse model finds that Cordyceps increased the interval to exhaustive exercise induced oxidative stress. SOD, Cat, and GPx were increased in the low, intermediate, and high dose Cordyceps groups. Oxidative stress markers MDA and 8-OHdG were lower in all groups
