Glycine: Uses and Risks

This post was written with Consensus AI Academic Search Engine – please read our Disclaimer at the end of this article. Glycine shows potential therapeutic benefits in various conditions, including psychosis risk syndrome, diabetic cataracts, ischemia-reperfusion injury, liver cancer prevention, and aging-related issues. However, its use is not without risks, such as neurological symptoms during certain medical procedures and potential interference with other treatments. Further research is needed to fully understand its efficacy and safety across different applications.

Uses of Glycine

1. Psychosis Risk Syndrome: Glycine has been explored as a treatment for the risk syndrome for psychosis. In pilot studies, glycine showed promising results in reducing positive and negative symptoms and improving cognitive function in patients without adjunctive antipsychotic medication. The studies reported large effect sizes for symptom reduction and potential cognitive improvements, suggesting glycine’s potential as a therapeutic agent in psychosis risk syndrome1.

2. Diabetic Cataract Prevention: Glycine has demonstrated protective effects against diabetic cataracts in animal models. It was found to inhibit aldose reductase activity, which is implicated in cataract formation, thereby reducing blood glucose levels and increasing plasma insulin levels in diabetic rats3.

3. Ischemia-Reperfusion Injury: Glycine has shown cytoprotective properties in skeletal muscle undergoing ischemia and reperfusion injury. In canine models, glycine preserved muscle function, reduced edema, and decreased muscle necrosis, indicating its potential for clinical use in similar human conditions4.

4. Liver Cancer Prevention: Dietary glycine has been found to prevent the development of liver tumors in rats exposed to the carcinogen WY-14,643. Glycine inhibited the progression of early foci to tumors, particularly larger tumors, suggesting its role as a chemopreventive agent5.

5. Aging and Oxidative Stress: Glycine, when combined with N-acetylcysteine (GlyNAC), has been shown to improve glutathione deficiency, oxidative stress, mitochondrial dysfunction, and other aging-related issues in older adults. This combination improved physical function and reduced inflammation, highlighting its potential benefits in promoting healthy aging6.

Risks of Glycine

1. Neurological Symptoms: During transurethral resection of the prostate, absorption of glycine 1.5% was associated with a higher risk of neurological symptoms, such as nausea, compared to mannitol 3%. This suggests that glycine absorption can lead to adverse neurological effects in certain medical procedures2.

2. Interference with Antipsychotic Treatment: In treatment-resistant schizophrenia, glycine as an adjunct to clozapine did not reduce symptoms and may have interfered with the antipsychotic efficacy of clozapine. This indicates potential risks when combining glycine with certain medications7.

3. Palatability and Adherence Issues: In a study on obsessive-compulsive disorder, glycine supplementation faced challenges with regimen adherence due to taste and nausea, leading to a high dropout rate. This highlights the importance of considering patient compliance and potential side effects in glycine treatment regimens10.
