The first week of purchasing the hydrogen supplement, I found myself to have a lot of energy. I finally could get at least a 7 hours of sleep! Before, I could only get 5 hours! I also have osteoarthritis in my left hip! I did have a right hip replacement two years ago and was also having a hard time putting on socks! I noticed the pain subsided after one week and after 3 weeks I am able to put on my socks with ease, even tying my shoe laces!
