The most ubiquitous supplemental source of the H-minus ion for the past 45 years in Japan and past 15 years in the USA has been so-called "alkaline ionized water", also known as "micro water", from kitchen countertop water ionizers. This water is more accurately called electrolyzed reduced water (ERW); which is the naming convention which most commonly appears in articles in scientific literature to denote this water.
This water is often called "reduced water" due to its reducing, or antioxidant activity, and has been called "microwater" by some commercial vendors due to the fact that the water exhibits a smaller cluster size than "normal" water.
There exist some people who deliberately ingest H- as a nutritional supplement for the health benefits, primarily its advantages as a primal antioxidant or primeval antioxidant, and one with extremely low molecular weight and size, allowing it access to many and varied tissues and levels of biochemical activity.
Regardless of the methodology you choose the important facts to remember are that the reproduction of negatively-ionized hydrogen brings us the most powerful antioxidant, a natural alkalizer, an anti-microbial agent, and a way to restore and maintain cellular fluid balance.
The most valuable benefits of seeking out the negative hydrogen substances are improving health, repairing tissue, reducing pain, increasing energy and reversing aging. The cells and the body as a whole are restored to and kept in the healthiest possible state.
