Yes,it's a very powerful antioxidant,and it's both water and fat soluble ulike the other antioxidants.It's also used to protect the eyes (detoxificator).I protects your liver in high doses but can be toxic uo to 600mg/day(though,no studies are made to prove this yet).It's common use is to help drive the carbs/protein into your muscles and help in better carb absorption(insuline sensitivity).It's better than chromium for this use.
