At each step of product development, we commit to rigorous scientific research. To ensure the efficacy and safety evidence of our products, HOHO heavily invests in scientific research. We've established multiple preclinical and clinical trials in many research partnerships.

In the meantime, with the efforts of our experts in regulation areas, our products are approved by reliable purity and safety regulative institutions. This is a major differentiation between us and any other company selling hydrogen supplement products.

We study our products in the preclinical trials to ensure the efficacy of hydrogen, and confirm the results in humans, so you can have products with scientific evidence.

Both preclinical and clinical trials are important to us. To provide rigorous scientific evidence, we cooperate with medical centres, universities, and research institutes to study the benefits of hydrogen in COPD, rheumatology, metabolism.

​

We also work with our scientific advisors to identify the better technology to elevate the products. Safety and efficacy tests will be done before entering the market.
