What Does Water Do For Us?

  • Water helps keep skin hydrated and plump. Drinking water can make you appear younger, while being dehydrated can make you feel sick.
  • Drinking water is associated with clearer skin
  • Water flushes our toxins and waste from the body and supports fluid balance
  • Drinking water before meals helps you eat a little less; thereby helping you to control calories
  • Helps keep your temperature normal
  • Lubricates and cushions your joints
  • Protects your spinal cord and other sensitive tissues

Questions About Hydrogen-Enriched Water

  • What is hydrogen water?
  • Hydrogen water or hydrogen-rich water (also called hydrogen enriched water) simply means normal water (H2O) that contains dissolved hydrogen gas H2. For example, there are carbonated waters or beverages (soda pop) which contain dissolved carbon dioxide gas (CO2), or oxygen water, which contains dissolved oxygen gas (O2). Similarly, you can have water that contains dissolved hydrogen gas.
  • How does it do that?
  • Our H2 bottles uses a titanium anode plate to create H2 using an electrolysis process.
  • Isn’t hydrogen gas explosive?
  • Hydrogen is the most energy-dense molecule by mass. But when the gas is dissolved in water it is not explosive at all, just like if you mixed gunpowder in water it wouldn’t be explosive either. Even when it is in the air, it is only flammable above a 4% concentration by volume, which is not a concern when talking about hydrogen-rich water.
  • Doesn’t water already have hydrogen in it because water is H2O?
  • The water molecule has two hydrogen atoms chemically bound to the oxygen atom. This is different from the hydrogen gas molecule (H2) which is just two hydrogen atoms bound only to each other. Here’s an example: we need oxygen (O2) to live, so why can’t we just get our oxygen from drinking water, H2O? It’s because the oxygen is chemically tied up in the water molecule. We need available oxygen gas (O2) that is not bound to other atoms or molecules. In the same way, for the dissolved hydrogen gas (H2) to benefit us, it must be in an unbound form and therefore available for therapeutic benefit.
  • I read that if you add hydrogen to water it makes hydrogen peroxide, is that true?
  • Water has the chemical formula H2O and hydrogen peroxide has the chemical formula H2O2, which by comparison contains an extra oxygen, not hydrogen. So, it does not form hydrogen peroxide. Therefore, hydrogen water and hydrogen peroxide are completely different substances.
  • Won’t any dissolved hydrogen gas immediately escape out of the water?
  • Yes, it does immediately start coming out of the water, but it doesn’t just vanish immediately. Depending on the surface area, agitation, etc., the hydrogen gas can stay in the water for a few hours or longer before it drops below a therapeutic level. This is much like carbonated water or soda that contains carbon dioxide gas (CO2), but because it does leave, it is best to drink the water promptly before it goes “flat.”
  • What does H2 taste like?
  • It is tasteless, colorless, odorless and non-metallic.
