Glycine Sleep Quality Meta-AnalysisData synthesis and subgroup analysis were performed via SMD, WMD, relative risk (RR), and 95% CI to evaluate the effects of rTMS and its influencing factors.1Cao Z (2026)Efficacy of repetitive transcranial magnetic stimulation for insomnia disorder: a systematic review and meta-analysis of randomized controlled trials.
Glycine Sleep Quality Meta-AnalysisThe rTMS group demonstrated markedly improved sleep quality compared with sham rTMS recipients in individuals with insomnia disorder.1Cao Z (2026)Efficacy of repetitive transcranial magnetic stimulation for insomnia disorder: a systematic review and meta-analysis of randomized controlled trials.
Glycine Sleep Quality Meta-AnalysisConclusion Independent rTMS and rTMS-medication combinations significantly improve sleep patterns and rest quality in patients with Insomnia Disorder.1Cao Z (2026)Efficacy of repetitive transcranial magnetic stimulation for insomnia disorder: a systematic review and meta-analysis of randomized controlled trials.
Glycine Sleep Quality Meta-AnalysisFirst-line treatments are limited by accessibility or side effects, necessitating alternative approaches.1Cao Z (2026)Efficacy of repetitive transcranial magnetic stimulation for insomnia disorder: a systematic review and meta-analysis of randomized controlled trials.
Glycine Sleep Quality Meta-AnalysisFailure to meet the recommended 7-9 hours of restful sleep per night is known to increase the risk of several health conditions, reason why regular and adequate sleep should be seen as a priority instead of an unnecessary commodity easily traded as required by the commitments of our busy lives.4Conti F (2026)Dietary Protocols to Promote and Improve Restful Sleep: A Narrative Review.
Glycine Sleep Quality Meta-AnalysisWhile both the quantity and the quality of sleep can be largely improved with relatively straightforward practices dictated by good sleep hygiene, emerging research suggests that dietary and supplementation protocols focused on certain foods, nutrients, and biochemical compounds with sleep-promoting properties can act as subsidiary sleep aids in complementing these behavioral changes.4Conti F (2026)Dietary Protocols to Promote and Improve Restful Sleep: A Narrative Review.
Glycine Sleep Quality Meta-AnalysisThe scope of this narrative review is to summarize the available evidence on the potential benefits of selected nutraceuticals in the context of circadian rhythm and sleep disturbances, namely melatonin, magnesium, omega-3 fatty acids, tart cherry juice, kiwifruit, apigenin, valerian root, L-theanine, glycine, ashwagandha, myoinositol, Rhodiola rosea, and phosphatidylserine.4Conti F (2026)Dietary Protocols to Promote and Improve Restful Sleep: A Narrative Review.
Glycine Sleep Quality Meta-AnalysisHumans spend approximately one third of their life asleep but, as counterintuitive as it may sound, sleep is far from being a quiet state of inactivity.4Conti F (2026)Dietary Protocols to Promote and Improve Restful Sleep: A Narrative Review.
