Thats a good question, but as far as DNP is concerned, I dont think there has been enough research done to determine if somthing could counter it. Also keep in mind the number was like 1 in 100,000...hell, that many people allready get cataracts.
Im imune, I allready had them and had both lenses removed , not fun.
I remember reading an article before about dnp, and they suggested a supplement to take to help guard against them. (No, it was not sponsored by any supplement company) Thing is, now that I am almost ready to give it a go, I went back to the article, and it is gone of course. So now I just need to finish my supplement shopping and I can begin.
