What the research says about glycine
Educational summaries of published research on glycine; not product-specific claims. AOR Glycine's claim is the traditional/authorized use under NPN 80006852.
Fewer night awakenings from a glycine-rich peptide
In physically active men with sleep complaints, a glycine-rich collagen peptide taken before bed reduced polysomnography-recorded awakenings and improved next-morning cognitive performance.
Human RCTSleep-promoting action traced to the brain's clock center
In rats, oral glycine promoted sleep and lowered core body temperature by acting on NMDA receptors in the suprachiasmatic nucleus, the brain's master circadian clock.
MechanismA safe amino-acid sleep strategy
Reviewed as shortening time to fall asleep and improving sleep quality without next-day grogginess.
ReviewRaises a calming brain chemical after oral dosing
Oral glycine increased extracellular serotonin (but not dopamine) in the prefrontal cortex of rats, a possible mechanism behind its calming, sleep-supportive effects.
MechanismAn inhibitory neurotransmitter
Glycine acts as an inhibitory neurotransmitter and an NMDA-receptor co-agonist in the brain and spinal cord.
MechanismStudied for memory & attention
Glycine has been studied for effects on memory and attention via NMDA-receptor modulation.
Human studyReduced fatigue, better performance
Glycine reduced fatigue and improved next-day psychomotor performance in sleep-restricted volunteers.
Human studyCognition in older adults (GlyNAC)
A 24-week pilot trial of glycine plus NAC improved cognition alongside metabolic and mitochondrial markers.
Pilot clinical trialRestored glutathione & insulin sensitivity
GlyNAC corrected glutathione deficiency, oxidative stress, mitochondrial dysfunction and insulin resistance over 24 weeks.
Pilot clinical trialGlycine can limit collagen synthesis
Glycine availability can be a limiting factor for collagen synthesis; supplementation increased collagen production in vitro.
ResearchCollagen's most abundant amino acid
Glycine makes up roughly one third of the collagen molecule, the main structural protein of skin, tendon and bone.
MechanismSkin is especially collagen-rich
Analysis of tissue composition found skin to be especially collagen-rich (an estimated 20-40% of protein), with glycine as collagen's single most abundant amino acid.
ResearchCollagen amino acids & healthy aging
A glycine-rich collagen amino-acid composition was associated with reduced biological age and improved healthspan markers.
ResearchSupported muscle strength (GlyNAC)
In the GlyNAC trial, supplementation improved muscle strength alongside metabolic markers in older adults.
Pilot clinical trialHelped preserve tissue after injury
In irradiated rats, dietary glycine helped preserve colon-wall thickness and the mucosal surface, supporting tissue repair after injury.
ResearchHelped metabolic-syndrome markers (RCT)
Oral glycine improved markers of oxidative stress and metabolic health in patients with metabolic syndrome.
Human RCTRoles in metabolic regulation (review)
Reviews glycine's roles in protein synthesis, metabolic regulation and cytoprotection.
ReviewAntioxidant & anti-inflammatory roles
Reviewed for roles in antioxidant defense, anti-inflammation and metabolic regulation.
ReviewWhy 'conditionally essential'
Endogenous glycine synthesis may not meet full metabolic demand, supporting dietary intake.
ReviewA central one-carbon building block
Glycine feeds one-carbon metabolism and is a precursor for glutathione, creatine, heme and nucleotide synthesis.
ReviewNaturally sweet amino acid
Glycine is the simplest amino acid and was identified among the naturally sweet-tasting amino acids in human sensory testing.
Human studyCytoprotective in gut & liver
Glycine has shown cytoprotective effects in experimental models of gut and liver injury.
ResearchCalms inflammatory signaling
Glycine activates glycine-gated chloride channels on immune cells, dampening inflammatory signaling.
MechanismWell tolerated even at high doses
In a clinical trial using glycine at roughly 0.8 g/kg bodyweight per day (about 50-60 g/day for most adults), treatment was well tolerated over six weeks.
