100 Scientific Studies of Hydrogen Water

Ionized Water, Hydrogen Water & Hydrogen Gas

The body has been found to have been helped or healed naturally with free-hydrogen. Free-hydrogen is a unique molecule of two hydrogens, bonded together, but not bonded to any other elements. You can only get free-hydrogen in ionized water, hydrogen water or hydrogen gas. Hydrogen water can be produced by either a water ionizer or a hydrogen machine, and in either case is very therapeutic, as the studies on this page show.

Click here to learn more about ionized water and hydrogen water. My personal preference is the water ionizer, because my body needs more alkalinity to help keep body detoxified. Here's my testimonial.

The research on this page shows the positive effects that hydrogen water, hydrogen by itself (as a gas) and hydrogen in ionized water have on the body. On this page you can click on links to both the human studies and animal studies, below. Within each category of disease, I have placed the human studies first, followed by the animal studies.

The terrific therapeutic benefits of water ionizers (ionized water), hydrogen water machines (hydrogen water) and hydrogen gas machines (hydrogen gas) have been demonstrated thousands of times in scientific studies. One hundred of these studies are described (and linked to the actual research) on this page.

About the Articles

These are a compilation of a variety of hand-picked, relevant articles, which are a good sample of the scientific literature about hydrogen water, water ionizers, and hydrogen gas to date. Each study listed is linked to the published abstract of the article. Each of the article links will open up a new page in your browser. Note: Ionized water is typically called "electrically reduced water" or ERW in the studies. Hydrogen, in hydrogen gas and hydrogen water, is often called "molecular hydrogen". Ionized water is not the same as hydrogen water, but can be called hydrogen water because it has a lot of molecular hydrogen in it. Ionized water is produced in a water ionizer and hydrogen water is produced with either a hydrogen water machine or hydrogen gas generator.
