There is one study-- and this is a rat study, but you can equate the dose of toxicity in rats and humans. They did not give these rats any antioxidants, but it increases a couple of different proinflammatory markers. One is GGT, or gamma glutamate transferase. It comes from both the testes and the liver, and one is alkaline phosphatase, also known as Alkphos, again, coming from both areas.
