Review of HTWO Hydrogen Water

I previously wrote an article breaking down various technologies to make hydrogen water or deliver molecular hydrogen through internal hydrogen production (also, briefly touching on hydrogen inhalation). Despite my assessments being based on fact, supported by independent third parties, and being completely testable and reproducible, we get numerous emails claiming we are slandering other technologies for our own gain, with "made up results." The only solution was to commission lab reports, video my own testing, and break it all down as clearly as possible.

This week, I am breaking down HTWO hydrogen water, one of the most popular and widely advertised commercial entities on the market. Below you will find a lab report testing hydrogen concentration, my own video testing hydrogen concentration, my breakdown of its marketing claims and lack of substantiation, and a comparative table examining differences between HTWO hydrogen water and Rejuvenation hydrogen tablets for dosage, concentration, legal status, supporting research, and value.

HTWO Hydrogen Water Label Claims

Of note, the International Hydrogen Standards Association (IHSA) has set a minimum observed threshold of 0.5mg/L concentration with a dosage of 1L consumed, for 0.5mg of H2, as the lowest amount of hydrogen that could potentially create a benefit in any (but not all) conditions where hydrogen water has shown to be potentially effective. HTWO delivers 0.25mg per pouch, meaning that two pouches are needed for the minimum dosage that could even potentially be therapeutic. Of course, hydrogen concentration matters; hydrogen benefits have been shown to be both dose- and concentration-dependent. "The Metabolic Beverage"

"Supports Metabolism at the Cellular Level for Endurance and Recovery"

HTWO is going all in with the metabolic claims, but there is one big problem: the lowest dosage given to participants in two clinical research trials for metabolic outcomes, 0.5mg a day, is double the dosage it provides in a pouch, and it has no statements as such on its packaging. Neither of these trials used HTWO water in their study, either. Further, as i discussed in my breakdown of our own study on metabolic syndrome, there is a very clear dose-, concentration-, and duration-dependent  response with hydrogen water for metabolic outcomes. For context, to replicate the dosage administered in our study using HTWO, 48 pouches (24L of water!) would need to be consume in short order. This would certainly kill an individual from water poisoning, and doesn't even reconcile the differences in concentration, which is likely a factor in our physiological response.

The company was founded, and appears to be led, by an MD/PhD (Biochemistry and Molecular Biology), Dr. Cody Cook, and the company tagline is "Born from Science" (which they've trademarked). Unfortunately, it seems as if the final product was born developmentally disabled.

Another important note: Despite Dr.Cook founding HTWO many years ago and being involved in research and academia, he has not yet published a paper demonstrating any results from his product or from the dose and concentration his product delivers. In fact, it does not seem he has published a paper on molecular hydrogen at all. Doesn't scream of confidence, in my opinion.

Lab Report

H2 Blue Video

I wanted to give HTWO a fair shake and know that virtually no one has used the chemical reagent used to test molecular hydrogen levels in water, H2 Blue, more than I have; Randy from H2 Sciences, the manufacturer of H2 Blue, and I have joked about who has used the reagent more, him or himself. That said the concentration is so low that I did not expect any deviation. I did record one more drop than the lab report did, so I will used the higher reading, my own, to evaluate dosage for HTWO hydrogen water.
