I took it first thing in the morning and power heaved. I've since done some more research and I would have to advise caution.
Calcium Hypochlorite (mms2) breaks down into two substances when mixed with water. Hypochlorous Acid is one and Mr. Humble seems quite happy to bring this up. Why doesn't he bring up the fact that the other component is Calcium Hydroxide? BECAUSE IT'S POISON TO THE BODY! Take this stuff at your own risk but do your own research. Look up the dangers of Calcium Hydroxide before you put this in your stomach. Please.
