How the Open Cup Works

[NOTE: Not all H₂ tablets are the same. While most tablets share a common chemistry, differences in ingredient purity, particle size, and manufacturing process can and will affect final hydrogen concentrations (ppm). This demonstration is specific for DrinkHRW’s Rejuvenation Hydrogen Tablets but could be used as a guide for others. While this website is not specifically focused on marketing, at the farm we use DrinkHRW’s Rejuvenation Hydrogen Tablets because of both its ability to produce a higher H2 concentration and its active participation in research programs such as those seen here. We do recommend it to others.]


The saturation point of H2 gas in water at room temperature with no external force is 1.6 mg/L or 1.6 parts per million. Typically most machines operating under no pressure will only get a fraction of this, with well-maintained ionizers often retaining levels as low as 0.1 mg/L(0.1 PPM) and the best models struggling to achieve 1 mg/L(1 PPM). Often these machines produce adequate amounts of gas, however, they produce it in a manner that encourages the gas to form large bubbles and immediately dissipate into the air.

Our Rejuvenation hydrogen tablets and patent-pending IP revolves around creating a consistent and prolonged burst of nano-bubbles which have shown to be able to remain stabilized in water for relatively long periods of time. Notice in image 1, our stream looks much like bubbling gas into the water would, the bubbles are traveling up in an almost perfectly straight line.

Image 2 starts to paint a different picture. Notice how instead of dissipating into the air, leaving little left in the water, our cloud of nano-bubbles rolls downwards when it comes to the surface, intensifying in image 3 and beginning to spread throughout the entire container.

Image 4 shows the water with a fully formed cloud, dense with H2 gas. While some of the best technologies on the market struggle to achieve 30% of gas produced remaining in solution, our measurements have been as high as 90%! Just like with other vitamins and minerals where it doesn’t matter how much you consume but how much is bioavailable, with h2 gas it doesn’t matter how much is produced it matters how much remains in the water for consumption. 

The truly amazing detail in all of this is due to our knowledge on nano-bubbles remaining in solution undissolved for extended periods of time and discoveries on how to create an ideal stream of nano-bubbles to take advantage of this, our Rejuvenation hydrogen tablets have been measured as high as 9 mg/L*, or 9PPM in a 500ml container. One tablet delivering 4.5mg of H2 in a glass- to give full context, the expensive ionizers producing 0.1mg/L would need 45L of water consumption, or 90x the volume to get the same dosage. Watch our H2Blue demonstration showing how powerful our tablet is *measured in 500ml of water, 9mg/L equates to 4.5mg dosage of H2 or the equivalent of 4.5mg/L or 4.5ppm in 1L of water.
