What a life changer. I tried this product after reading and becoming inquisitive about arthritis and water quality. After a few weeks there was little to no change to my arthritis. After a few months I now have "barely noticeable" pain in my hand (fingers and wrists). When away from home I do without the filtered drinking water for 2-3 days and notice the pain begins to return. I will be taking jug with me when travelling in the future. I also notice that the constant swelling and reddish tinge on my arthritic joints has reduced significantly. I am so pleased I persisted with this product. Having experimented with other lifestyle changes ie reduced caffeine intake, reduced alcohol consumption etc, I have now achieved the improved health benefits I had wished.
