Clinical TrialHighlightedMolecular hydrogen modulates brain glutamate/GABA-glutamine cycle in overweight humansMHID-5537085PMID: 375607462023Archives of Medical ScienceDarinka Korovljev, Jelena Ostojic, Nikola Todorovic, Sergej M OstojicIntroduction: We evaluated whether 12-week intake of molecular hydrogen (H2) in 5 overweight adults (3 women; age: 50.2 ±11.9 years, body mass index: 29.4 ±2.1 kg/m2) affects brain levels of the glutamate-glutamine-GABA cycle, critical amino acid neurotransmitters in the mechanism of neuronal activation during appetite regulation. Methods: A 1.5-T single-voxel proton magnetic resonance spectrosco
