Hydrogen water is regular water that has been infused with molecular hydrogen gas. This process increases the concentration of hydrogen molecules in the water, which some believe may offer health benefits. It is often marketed as a supplement that can enhance hydration and provide antioxidant properties. Research on hydrogen water is still ongoing, and while some studies suggest potential benefits, such as reducing inflammation and improving athletic performance, more extensive research is needed to confirm these claims. It is important to note that hydrogen water is not a replacement for a balanced diet or proper hydration practices.
