Be careful what water you mix this with. I found that the PH in well water does not drop when MMS is added it will stay around 6.5 to 7, The same for my tap water, However when you use some of the distilled or purified water(bottled water) the PH will drop all the way down to 2, This is very acidic and I don't see how it can be good for you. I believe MMS is a good product,I use it with well water, I believe there is something in the bottled water that causes this, Maybe even something they use to "purify" the water with. "Watch the water"
