That should keep you busy for while. As you can see, most of the studies were done in the orient. They are way ahead of us in molecular hydrogen research and application, due to most of the higher ups in the FDA working for, or vying for a job with, the drug companies. Molecular hydrogen for health purposes is just in it's infancy here in the US, but it's inevitable, since it works so well, and there are no side effects. The upper limit for breathing it is 4.6%, for obvious reasons, and water infused with molecular hydrogen maxes out at about 1.6ppm. As a chemist, you should know that the hydrogen will dissipate; hydrogen molecules will even go through quartz glass. Storing hydrogen infused water in aluminum containers will reduce the dissipation, but I can't recommend this, as some aluminum ions will end up in the water. Likewise, producing hydrogen water via mettalic magnesium is not recommended. Although magnesium is an essential mineral, it's best to get it from plants, where it is easily assimilated. The hydrogen infused water from my machine should be drunk within a few hours. In an open container, it will have mostly dissipated after 24 hours.
