Scientific, peer-reviewed literature usually refers to ionized water as "electrolyzed reduced water", or ERW. Scientific research and literature have shown that ERW exhibits strong health-enhancing benefits. Most importantly, it has an antioxidant effect. This is due to the presence of negative hydrogen ions. H-ions are present in the water in a clustered form, wherein each negative hydrogen ion is surrounded by a cage (or cluster) of water molecules. The ionized water also shows a reduced cluster size and reduced surface tension. The reduced cluster size and reduced surface tension, which are created by the presence of the H-ion, are also believed to have beneficial health effects when the water is consumed.

The electrolysis treatment makes three important changes to the water chemistry :

1. Electrolysis changes the ORP value of tap water from +500mv to -150~-800mv.
Alkaline (Reduced) water carries a slight negative electrostatic charge (surplus electrons). This – ORP (Redox Potential) provides a powerful antioxidant benefit when consumed. It helps scavenge and neutralize harmful free radicals that are associated with aging and health problems.
Ionized Alkaline (Reduced) water with ORP values of -250 to -350 mV, donates its electrons to unstable oxygen radicals and blocks the interaction of the active oxygen with normal molecules. This reduces the active oxygen (AO) and renders it harmless. Undamaged biological molecules are less susceptible to infection and disease. Ionized Reduced water also inhibits excessive fermentation in the digestive tract by reducing indirectly metabolites such as hydrogen sulfide, ammonia, histamines, indoles, phenols and scatoles, resulting in a cleaner stool within days after reduced water is taken on a regular basis. In 1965, the Ministry of Welfare of Japan announced that reduced water obtained from electrolysis can prevent abnormal fermentation of intestinal microbes. The -ORP (Oxidation Reduction Potential) value of ionized water is a measure of the antioxidant benefit. The more negative the ORP value, the more scavenging benefit.
2.Electrolysis changes the pH value of the water
Alkaline water helps balance the body's chemistry and maintain optimal pH levels. Drinking alkaline water improves the body's ability to buffer acids and flush acidic residues.
The pH level of tissues, body fluids and organs is tightly regulated. The body maintains a blood pH level at around 7.35 -7.45. Enzymes and other proteins function properly within this optimum pH range. Acidifying foods in our diet (such as meats, starches, sugars, alcohol and other processed food products), or other environmental may stress the body to maintain a pH balance within this optimal pH range. The body uses many methods to maintain pH values within the optimal range. Most importantly, it relies on high pH fluids, such as water, that act as solvents to neutralize acid residues. It also utilizes electrolyte buffers like sodium, calcium and potassium to bind acids, that are then removed through the urine. But some of the methods it uses to adjust pH may have negative effects in the long term. People with a generally trending acidic physique tend to have a weaker immune system and may experience a general physical deterioration, emotional tension & trepidation, poor metabolism, a weaker excretion system, and a propensity to constipation. Long-term suffers are also prone to illnesses such as hepatitis, cancer, palsy, hypertension, heart disease, diabetes, nervousness disease and others. Regular use of Alkaline drinking water can help flush acidic residue from the body and help restore our optimal pH balance. In countries around the world, many cities sterilize their water with Chlorine. Chlorine causes drinking water to become acidic. Alkaline water also contains many beneficial mineral ions like calcium, magnesium, potassium and other beneficial trace minerals. These electrolytes carry a (-) charge that improves the absorption rate in the body.
3.Electrolysis temporarily alters the molecular structure of the water
Promotes better Hydration The bonds between the water molecules are fragmented and the cluster size of the molecule becomes temporarily smaller. This smaller molecule cluster size allows for better absorption by the body. This promotes better hydration and quicker recovery from fatigue.
Other Benefits of Alkaline Water include:
  1. Cleansing the liver – Alkaline water has been shown to increase levels of antioxidants that protect the liver and help it work more efficiently.
  2. Lowering Cholesterol Levels – research has shown that drinking alkaline water can reduce your cholesterol level, while increasing the ratio of good (HDL) cholesterol to bad (LDL) cholesterol.
  3. Weight Loss - Alkaline water can help the body rid itself of stored fatty acids. Drinking water naturally suppresses the appetite and helps the body metabolize fat.
