II. Electrolyzed Reduced Water Explained

A. What is Electrolyzed Reduced Water (ERW)?

ERW is produced through a process called electrolysis, where an electric current is passed through water, splitting it into alkaline and acidic components. The alkaline water generated through this process is known as ERW and is claimed to possess various health benefits.

The Electrolysis Process: ERW is generated by passing low-voltage electric current through water, typically obtained from a tap source. This process leads to the separation of water into alkaline and acidic components, resulting in ERW that is believed to be antioxidant-rich.

Molecular Structure and Properties of ERW: ERW contains negatively charged hydroxyl ions (OH-) and positive hydrogen ions (H+). The presence of these ions is believed to contribute to its purported health benefits.

Difference Between Alkaline and Acidic ERW: ERW can be further categorized into alkaline and acidic ERW, depending on the pH level. Alkaline ERW typically has a pH above 7, while acidic ERW has a pH below 7.

B. Claims and Alleged Benefits of ERW
