Have never been able to find this information so easily on Google before. Even discussing the much maligned "DON"T DRINK BLEACH!" and describing it as "without side effects" LOL. Interdasting.

Be very careful with what water you mix the MMS with do not use bottled water as they already have a water purifier in them. When you mix MMS with bottled water the PH goes to 2 which is very acidic and could damage your liver and kidneys.Well water is the best. Always check the PH before drinking MMS if it is below 6 do not drink it.
MMS needs to be taken using distilled water. You can check the ph of the distilled water and if it’s not there it should be you can add a 1/4 teaspoon of baking soda to bring the ph where it should be.
What I was saying is that the distilled water that you buy has water purifier in it. Distilled water should have a PH of 7 the stuff you buy is at 6 and when you add the MMS it will go to 2. I have ran this test with 6 different bottled waters some say distilled some say spring some say purified the result is the same.
Distilled water from an aircon machine is OK.
