TL;DR
Breathing in hydrogen gas or drinking hydrogen-rich water for six months can improve liver function and reduce body fat in rats.
Key Finding
Six months of daily hydrogen exposure reprogrammed rat liver metabolism to reduce fat production and increase fat breakdown, with changes centered on NADP-dependent pathways.
Summary
Researchers gave rats molecular hydrogen (H2) daily for 6 months through drinking water or breathing hydrogen gas, then examined how it affected liver function and metabolism. The rats showed reduced fat production in the liver, increased fat breakdown, loss of belly fat, and lower blood lipid levels. The study identified that hydrogen works by changing how the liver uses a molecule called NADP, which is involved in many metabolic processes.
Practical Takeaway
This rat study provides the first molecular evidence for how hydrogen might affect metabolism and fat storage, but it's important to note this is animal research only. Whether these effects translate to humans remains unknown, and clinical trials would be needed before drawing conclusions about hydrogen water's effects on human metabolism or weight management.
Abstract
Molecular hydrogen (H2) has emerged as a new therapeutic option in several diseases and is widely adopted by healthy people. However, molecular data to support therapeutic functions attributed to the biological activities of H2 remain elusive. Here, using transcriptomic and metabolomic approaches coupled with biochemistry and micro-CT technics, we evaluated the effect of long-term (6 months) and daily use of H2 on liver function. Rats exposed 2 h daily to H2 either by drinking HRW (H2 dissolved in H2O) or by breathing 4% H2 gas showed reduced lipogenesis and enhanced lipolysis in the liver, which was associated with apparent loss of visceral fat and brown adipose tissue together with a reduced level of serum lipids. Both transcripts and metabolites enriched in H2-treated rats revealed alteration of amino acid metabolism pathways and activation of purine nucleotides and carbohydrate biosynthesis pathways. Analysis of the interaction network of genes and metabolites and correlation tests revealed that NADP is the central regulator of H2 induced metabolic alterations in the liver, which was further confirmed by an increase in the level of components of metabolic pathways that require NADP as substrate. Evidence of immune response regulation activity was also observed in response to exposure to H2. This work is the first to provide metabolomic and transcriptomic data to uncover molecular targets for the effect of prolonged molecular hydrogen treatment on liver metabolism.
