Thanks for the website info. I have read it, don't really understand it fully, will need more study.
I use a reverse osmosis water filtration system at home and it always tests at the lowest pH on my paper, which is 5.5. I bought some Alkalife drops and have been using them according to directions. Of course, the water still tests 5.5, but my saliva after drinking this water tests in the alkaline range, where it does not if I just drink the RO water without additives.
