We found in our previous study that glycine ingestion (3 g) before bedtime significantly produced subjective sleep effects in volunteers who had been continuously experiencing unsatisfactory sleep. Further, a series of published reports has shown that the safety of glycine is relatively high. The present study was conducted to assess acute adverse events or a daytime sleepiness effect after using a 3-fold higher dose (9 g) than the previous study. The results indicated that 9 g doses of glycine…

The Effects of Glycine on Subjective Daytime Performance in Partially Sleep-Restricted Healthy Volunteers
Glycine modulates certain neuropeptides in the SCN and this phenomenon may indirectly contribute to improving the occasional sleepiness and fatigue induced by sleep restriction.
Glycine supplementation to improve insulin sensitivity in humans
Findings did not provide sufficient evidence to demonstrate that glycine supplementation may improve insulin sensitivity and lipid profile in insulinresistant (IR) normoglycemic subjects, and the implementation of a larger investigation with sufficient power is necessary to fully test the hypothesis.
Glycine ingestion improves subjective sleep quality in human volunteers, correlating with polysomnographic changes
In human volunteers who have been continuously experiencing unsatisfactory sleep, effects of glycine ingestion (3 g) before bedtime on subjective sleep quality were investigated, and changes in
Meta-Analysis of the Efficacy of Adjunctive NMDA Receptor Modulators in Chronic Schizophrenia
Taking into consideration the number of trials and sample size in subgroup analyses, D-serine, NAC and sarcosine as adjuncts to non-clozapine antipsychotics have therapeutic benefit in the treatment of negative and total symptoms of chronic schizophrenia.


Adjunctive high-dose glycine in the treatment of schizophrenia.
This study evaluated the degree to which symptom improvements might be related to alterations in antipsychotic drug levels in an additional group of 12 subjects and found that glycine treatment was associated with an 8-fold increase in serum glycine levels, similar to that observed previously.
Effect of clozapine and adjunctive high-dose glycine in treatment-resistant schizophrenia.
Preliminary data suggest that glycine may interfere with the antipsychotic efficacy of atypical neuroleptics such as clozapine.
Placebo-controlled trial of glycine added to clozapine in schizophrenia.
These data, combined with data from previous trials with D-cycloserine and glycine, suggest that agonists at the glycine site may be less effective when combined with clozapine than they are when Combined with conventional antipsychotics.
The metabolic response to ingested glycine.
The data are compatible with the hypothesis that oral glycine stimulates the secretion of a gut hormone that potentiates the effect of insulin on glucose removal from the circulation.
Efficacy of high-dose glycine in the treatment of enduring negative symptoms of schizophrenia.
Glycine-induced augmentation of NMDA receptor-mediated neurotransmission may thus offer a potentially safe and feasible approach for ameliorating persistent negative symptoms of schizophrenia.
Subjective effects of glycine ingestion before bedtime on sleep quality
The results suggest that glycine produced a good subjective feeling after awakening from sleep, and significantly improved the following elements: “fatigue’, “liveliness and peppiness”, and “clear-headedness”.
The nature of human hazards associated with excessive intake of amino acids.
A brief summary of the available evidence regarding the safety of individual amino acids when taken in excess relative to the amounts absorbed from dietary protein is provided.
Amelioration of negative symptoms in schizophrenia by glycine.
Significant improvement in negative symptoms occurred in the group given glycine but not in the groups given placebo, suggesting that potentiation of NMDA-receptor-mediated neurotransmission may represent an effective treatment for neuroleptic-resistant negative symptoms in schizophrenia.
