I find this product extremely useful. Within 24 hours I was able to notice the ph change. Within 7 days I noticed a change in my joints, skin, and digestion. On top of it all, I could really feel the difference all this was making. I have suffered from gout for 20+ years and getting a non-acidic form of Vitamin C that also increases body ph to basic is almost a miracle. This is a good natural way to treat gout and get the Vitamin C your body needs on a daily basis.
