My friend Dolly Jewel recommended the H2 tabs to me. I had been thinking about something like that for a while I asked daughter who is a critical care RN if she had ever heard of something like this. I was surprised when she told me she hydrogen. That was all I needed to hear. I ordered two packs. I started feeling a difference a few day later. I definitely will keep taking it!
