WHAT IS GLYCINE?

Glycine is an important non-essential amino acid. It acts as a precursor of several key metabolites, such as glutathione (our body’s main antioxidant), creatine, purines, and porphyrins (1)1. Razak MA et al. Multifarious Beneficial Effect of Nonessential Amino Acid, Glycine: A Review. Oxid Med Cell Longev. 2017;2017:1716701..

In general, under normal dietary conditions, glycine is not sufficiently synthesized. Mostly due to the decrease in the consumption of animal parts other than muscle tissue, such as bones, skin, and tendons, glycine intake has been reduced and methionine intake has increased. This alters the glycine:methionine ratio. This imbalance can be corrected by increasing glycine intake, providing a protective effect (2)2. Sanchez-Roman I et al. Regulation of longevity and oxidative stress by nutritional interventions: role of methionine restriction. Exp Gerontol. 2013 Oct;48(10):1030-42..

 
 

BENEFITS OF GLYCINE SUPPLEMENTATION

This amino acid is crucial in various functions of our body. According to recent scientific studies, glycine supplementation has the following benefits:

– Antioxidant function: Especially when combined with NAC (N-Acetyl Cysteine), increases the levels of glutathione, our main antioxidant. Thus improving oxidative stress, mitochondrial dysfunction, inflammation, and ageing (3)3. Kumar P et al. Glycine and N-acetylcysteine (GlyNAC) supplementation in older adults improves glutathione deficiency, oxidative stress, mitochondrial dysfunction, inflammation, insulin resistance, endothelial dysfunction, genotoxicity, muscle strength, and cognition: Results of a pilot clinical trial. Clin Transl Med. 2021 Mar;11(3):e372..
– Sleep quality and neurological functions: Due to the importance of glycinergic regulation during the REM sleep phase, glycine plays a relevant role in the physiological regulation of sleep. It improves the subjective quality of sleep and reduces sleepiness and fatigue during the day in people with insomniac tendencies or restricted sleep time (4)4. Bannai M et al. The effects of glycine on subjective daytime performance in partially sleep-restricted healthy volunteers. Front Neurol. 2012 Apr 18;3:61..
– Exercise: Plasma levels of glycine decrease after exercise due to increased utilization of this amino acid in collagen synthesis. This suggests an increased need for glycine after exercise (5)5.
