Chromium. So is good such as Chromium 3 and such bad such as Chromium 6. Now with the good Chromium good things happen such as good health and good bones and good life and good good. Chromium 6 now this stuff...this stuff feelsbadman. I mean if you like your self some first class death then hey grab your self a front ticket to the chromium 6 show and have a good time. Now the health stuff. As I stated the 3 version is good and neat and nice for you and can help if used correctly, but the 6 kindis bad and will lead to a various kind of cancer and then death if to much is taken in by the body. So the point of this all really is just make sure your water is good. Check it, clean it, wash it...some how, and ask that water guy in your town to make sure that your water is good for you. Because cleaner water leads to a cleaner life.
