H2 Apprentice
A Course to Get You Started
This course is perfect for the person who isn’t 100% sure they are ready for the Level 1 Certification Courses. This course is an important confidence booster that you can complete the Level 1 Certification courses without as big of an investment.
Learn About MHI and Molecular Hydrogen!
The H2 Apprentice course covers the very basics, nothing too complicated! Learn about the certification program and get your feet wet with some of the basics. The first two modules are taken from Course 101 of the MHI Certification. Then we jump into a few basic chemistry principles. Finally, we dive right into what hydrogen is, what hydrogen water is, and some of its benefits. This is a preliminary course to prepare you for the Level 1 Certification Courses in case you are feeling like you want to test it out first.

The Complete Guide to Molecular Hydrogen Therapy
Who is this guide for? This guide provides a high-level overview of molecular hydrogen therapy and links to deeper, topic-specific articles for readers who want more detail. What is Molecular Hydrogen? Molecular hydrogen is a gas. It is made of two hydrogen atoms. These atoms are bonded together with a nonpolar covalent bond, which means…

Hydrogen: An Emerging Medical Gas
INTRODUCTION Molecular hydrogen (i.e. H2 gas) is gaining significant attention from academic researchers, medical doctors, and physicians around the world for its recently reported therapeutic potential[1]. One of the earliest publications on hydrogen as a medical gas was in 1975, by Dole and colleagues from Baylor University and Texas A&M[2]. They reported in the journal Science that hyperbaric (8…

Calculating The Dose Of H2
What Is “ppm”? The ppm is an acronym for “parts per million”, a unit of measure that describes how much of one substance (called the “solute”) is dissolved in a sample of water (called the “solvent”). This is a measurement of concentration (or density), which can often be helpful in our daily lives. The ppm…

Hydrogen: Alternative Fuel To Alternative Medicine
(Also published on the Foundation for Alternative and Integrative Medicine website, September 2018) Hydrogen gas (H2) has been extoled for its use in “green energy” as an alternative fuel, but biomedical research over the past decade suggests it also has therapeutic biological benefits. For example, the preliminary 1000+ preclinical and clinical studies have reported hydrogen to have…

Flammability Risks of Hydrogen Inhalation
Hydrogen is a flammable gas, which means flammability must be addressed openly and accurately when discussing hydrogen inhalation. At the same time, flammability risk is often misunderstood or understated. Understanding when hydrogen is flammable, and how systems are designed to manage that risk, is essential for responsible education. When Is Hydrogen Flammable? Hydrogen gas is…

Nasal Cannula Considerations for Hydrogen Inhalation
Nasal cannulas are commonly used as a delivery interface for hydrogen inhalation because they are simple, familiar, and allow users to breathe normally during sessions. However, using a nasal cannula introduces specific considerations related to delivery efficiency, dilution, comfort, and safety that are important to understand. How Nasal Cannulas Affect Hydrogen Delivery A nasal cannula…

Concentration vs. Flow vs. Duration
When discussing hydrogen inhalation, three terms are often used interchangeably (concentration, flow, and duration) but they describe different aspects of exposure. Understanding how these variables relate helps clarify research findings and reduces confusion when evaluating hydrogen inhalation systems. Concentration Concentration refers to the percentage of hydrogen gas present in the gas mixture. This can sometimes…
