Molecular hydrogen inhalation modulates resting metabolism in healthy females: findings from a randomized, double-blind, placebo-controlled crossover study.

Initially, molecular hydrogen was considered a physiologically inert and non-functional gas. However, experimental and clinical studies have shown that molecular hydrogen has anti-inflammatory, anti-apoptotic, and strong selective antioxidant effects. This study aimed to evaluate the effects of 60 minutes of molecular hydrogen inhalation on respiratory gas analysis parameters using a randomized, double-blind, placebo-controlled, crossover design.
