Glycine is a non-essential amino acid that is used in the treatment of schizophrenia, stroke, sleep problems, benign prostatic hyperplasia (BPH), metabolic syndrome, and some rare inherited metabolic disorders. It is also used to protect kidneys from the harmful side effects of certain drugs used after organ transplantation as well as the liver from the harmful effects of alcohol. Glycine may reduce the risk of psychosis. Other uses include cancer prevention and memory enhancement.
Athletes use glycine in order to enhance their performance and recovery, as glycine increases the secretion of the growth hormone.
Typically, humans get about 2 grams of glycine per day with ordinary food consumption. The main sources of glycine are protein-rich foods, such as meat, fish, dairy, and legumes.
It is not as widely known that glycine supplementation is one of the ways to potentially improve human life expectancy.
In recent research, published in a journal called “Aging cell”, it has been shown that glycine supplementation in mice results in a longer lifespan. This was true for both female and male mice, and the obtained result is highly statistically significant.
Research in humans has also determined that aging of some cell lines can be reversed and that genes responsible for producing glycine play a role in the aging process. It has also been shown that glycine is essential for the production of glutathione, which in turn is responsible for protection against oxidative stress. In turn, antioxidants help with preventing multiple aging-related diseases.
Moreover, glycine is known to possess a large number of protective properties (anti-inflammatory, immunomodulatory, cytoprotective, platelet-stabilizing and antiangiogenic effects) as was shown in numerous studies on rodents.
Probably, the best part about this is that glycine is cheap. You can buy 1kg of glycine in a powdered form for about 20$. It is also sold in a form of tablets and capsules to make intake more convenient.
