TL;DR
Drinking a special milk that boosts hydrogen gas production in the gut may help athletes recover better from intense workouts.
Key Finding
Men who consumed hydrogen-producing milk before intense exercise experienced significantly less muscle soreness the next day and showed reduced markers of exercise-induced cellular damage compared to those who received a placebo.
Summary
This small study tested whether a special milk drink that causes intestinal bacteria to produce hydrogen gas could help men recover from intense exercise. Compared to a placebo drink, the hydrogen-producing milk reduced muscle soreness the day after exercise, lowered markers of cellular damage in urine, and improved how the body cleared lactate (a byproduct of intense exercise) from the blood.
Practical Takeaway
This is a small pilot study in humans, so results are preliminary and would need to be confirmed in larger trials before drawing firm conclusions. The findings suggest that hydrogen gas produced by gut bacteria may help with exercise recovery, but more research is needed to understand whether this approach is practical or effective for typical athletes.
Abstract (excerpt)
This study aimed to examine the effects of hydrogen gas (H2) produced by intestinal microbiota on participant conditioning to prevent intense exercise-induced damage. In this double-blind, randomized, crossover study, participants ingested H2-producing milk that induced intestinal bacterial H2…
