A bundle of 7 in-depth, self-paced online modules. Most learners complete them in 4–6 weeks, depending on their pace.

You can take each course at your own pace. There are many quizzes, videos, and texts to read through. Depending on the time you set aside, you could finish the courses in a weekend. Most students average between 12 and 20 hours to complete the entire Level 2 Certification. However, many also take their time to actively learn and take in as much information as they can and may spend up to 40 hours on it. It’s up to you and the pace you want, and your background. It is encouraged that you complete the level 1 certification courses prior to beginning level 2.

No formal science degree required—but Level 2 expects more analytical thinking and comfort with basic chemistry/biology. It’s accessible to anyone willing to learn the science.

Not at this stage. We cover general mechanistic nuance and scientific context. Detailed therapeutic protocols are reserved for Level 3, which addresses application for specific conditions.

You earn the official H₂ Consultant Certification, signifying a strong scientific understanding of H₂ therapy.

If you purchase the bundle, you will have 6 months to complete the courses.
If you purchase an individual course, you will have 3 months access to the course.

For questions about the courses, you can always send us an email. You can also join the MHI Community for $7/month and ask specific questions there and learn from other H2 enthusiasts. You have the option to add the community at checkout.
The MHI Community also hosts monthly Q&A’s with Executive Director Tyler W. LeBaron, MSc., PhD. This is a exclusive opportunity to ask your specific questions and get them answered!

Expect a combination of multiple-choice and short-answer questions that test comprehension of underlying science and data interpretation. Think Level 1, but unpacked with more depth.

If you want to sell hydrogen products or services with credibility, this certification shows you’re not just repeating claims—you understand why H₂ works. It builds confidence, authority, and trust with clients.

The certifications can be taken for university credit. To access courses for university credit, please email courses@molecularhydrogeninstitute.org. Otherwise, courses will be taken through MHI’s learning platform.

The certifications are well-known in the hydrogen therapy industry. Some companies selling hydrogen products require their sales agents to have this certification, or they may even receive more commission by being certified. Many consumers want to purchase products from people who are MHI-certified.

Certifications expire every 2 years to ensure that MHI-certified students are up to date on the latest information and as a way to ensure MHI can be self-sustaining in accomplishing its mission to advance the research, education, and awareness of hydrogen as a therapeutic medical gas.
Read about why MHI requires recertification here.

This is to be determined. It could be retaking the courses entirely, or it could be a test-only. However it is done, it is your responsibility to maintain your prized certification.

MHI certifications are well-known in the industry of hydrogen as a potential therapeutic medical gas.

Yes. MHI does not promote, endorse, or recommend specific products or brands, but we do encourage consumers to purchase from someone who is MHI certified as it increases the likelihood that the product/claims are in line with the evidence. This also encourages people to take our certifications, which is essential for MHI to operate.
