Hydrogen Water is a type of water containing hydrogen molecules in water and is known to have the effect of selective elimination of harmful active oxygen. Harmful oxygen is overproduced due to drinking, smoking, overeating, stress, environmental pollution, chemicals, and ultraviolet rays, which cause oxidation in the human body, transforming and damaging DNA and cell tissue. It is known that about 90% of modern diseases such as cancer, diabetes, arteriosclerosis, high blood pressure, stroke, myocardial infarction, Parkinson’s disease, skin aging and atopy are related to harmful active oxygen.
