Hydrogen gas can be generated in small amount by hydrogenase of certain members of the human gastrointestinal tract microbiota from unabsorbed carbohydrates in the intestine through degradation and metabolism, which then is partially diffused into blood flow and released and detected in exhaled breath, indicating its potential to serve as a biomarker.

Many studies have shown that H2 therapy can reduce oxidative stress. This, however, contradicts radiation therapy and chemotherapy, in which ROS are required to induce apoptosis and combat cancer. Yet many studies show chemoprotective and radioprotective and some even show chemosentizing
Nevertheless there are some papers claiming ROS ↑ for cancer cells

Hydrogen Gas in Water is also used.
- the amount of H2 dissolved in solutions is limited: up to 0.8 mM (1.6 mg/L) H2 can be dissolved in water under atmospheric pressure at room temperature
