Hydrogen-rich water is also called hydrogen water. Modern medicine believes that the decay of matter is an acidification (oxidation) process. Breathing oxygen, smoking and drinking, and pollution sources in the environment will all produce a large number of peroxide free radicals in the human body, destroy cells and tissues at will, and cause genetic diseases and aging of the body. Active hydrogen can effectively scavenge free radicals in the body. The antioxidant activity of hydrogen-rich water exceeds all known antioxidants such as vitamin C, carrot and lecithin, and it has a strong preventive and therapeutic effect on allergic dermatitis, constipation, hypertension, diabetes and cancer caused by free radicals. Drinking water rich in hydrogen regularly can promote metabolism, keep every cell healthy automatically, remove body rust and delay aging.
