Randomized, crossover clinical efficacy trial in humans and mice on tear secretion promotion and lacrimal gland protection by molecular hydrogen.
The researchers found that administering a persistent H₂-generating supplement increased the human exhaled H₂ concentration (p < 0.01) and improved tear stability (p < 0.01) and dry eye symptoms (p < 0.05) significantly. These findings add human evidence supporting molecular hydrogen's therapeutic…
