I first used H2forLife in 2013-14 due to a severe back injury/pain which led to spinal fusion surgery. Because I felt so much better after recovering, I stopped drinking H2forLife. Now, at 63 years old, I started buying H2forLife again because of extreme lethargy and severe joint pain in my hands and feet (due to hereditary DJD). I am also buying the same order for my elderly neighbors (the husband is battling cancer and the wife is weak, not sleeping well, and has no energy). Each of us already has more energy than we did before and my joint pain/swelling is backing off.
