The major cause of an inflammation response in our bodies is because of the Reactive Oxygen Species (ROS). ROS is chemically reactive radical containing oxygen and is mostly formed as a byproduct of the body’s normal metabolism of oxygen. ROS has an important role in communication between cells and regulation of substances that move in and out of cells. However when in stress, the body reacts by giving an over-supply of ROS which in turn causes oxidative stress with effects such as inflammation The hydroxyl radical ( OH) is said to be the most harmful of ROS. Drinking hydrogen rich water is beneficial in dealing with the excess production of ROS ( OH). The Molecular hydrogen (H2) In the hydrogen rich water selectively bonds with the hydroxyl radical ( OH) producing the all beneficial water in the cells.
