Hydrogen is the lightest and smallest element.

Molecular hydrogen has the ability to penetrate into the brain cells where other substances can't reach. It quickly affects the respiratory system, the brain, and the vascular tissue as soon as inhalation starts, reducing and repairing physical damage.

Due to this discovery, there is ongoing research being carried out in various medical conditions, such as respiratory diseases, chronic obstructive pulmonary disease, brain fog, stroke, Parkinson's disease, and Alzheimer's disease.
