Deep ocean minerals followed by reverse osmosis to desalinate and concentrate the magnesium and other minerals and trace elements at the expense of sodium chloride. Over the past 15 years, there have been many new publications (over 40) establishing DOM as statistically significant with regards improved cardiovascular and metabolic function. Recent clinical research from Taiwan, Japan and Korea also shows statistically significant therapeutic health benefits from either topical or oral consumption of DOM. In 2009, scientists at the National Taiwan Ocean University, Keelung, Taiwan, published the first notable wistar rat treadmill fatigue study. Researchers used desalinated deep ocean water processed with ultra-filtration and
