Glycine is an amino acid that helps build muscle tissue and convert glucose into energy. It is considered a non-essential amino acid because the human body can produce it on its own. Glycine is important for maintaining a healthy central nervous system and digestive system, and it provides antioxidants that protect against certain types of cancer. The body uses glycine to help build normal strands of DNA and RNA, the genetic material needed to form cells and ensure proper function. It prevents muscle breakdown by increasing the amount of creatine in the body. Glycine is not only found in high amounts in muscle, but also in high concentrations in skin and other connective tissues. Collagen, which maintains the firmness and elasticity of skin and connective tissue, is one-third made up of glycine. Without glycine, it is difficult for the body to repair damaged tissue; the skin also sags due to UV radiation, oxidative and free radical damage, and wounds are also difficult to heal.
Glycine is considered a glycogenic amino acid that supplies the body with the glucose it needs to produce energy. It helps regulate blood sugar levels, so glycine supplements can be used to treat symptoms of low energy and fatigue in conditions such as hypoglycemia, anemia, and chronic fatigue syndrome. Glycine is important for digestive health. It helps regulate the secretion of bile acids that digest fat and is an active ingredient in many commercial antacids. Glycine is essential for central nervous system function. Research has shown that this amino acid can help suppress neurotransmitters that cause seizures, hyperactivity, and manic-depressive disorders. When needed, glycine can also be converted into another neurotransmitter, serine, which is beneficial in managing schizophrenia. Currently, there is a lot of research on the effectiveness of glutamate in the treatment of schizophrenia; it has been shown to help improve memory loss from schizophrenia, Parkinson's disease, Huntington's disease, jet lag and overwork.
From the preliminary research results, the prospects for the treatment of cancer are very optimistic, and it is helpful to prevent the development of cancerous tumors and melanoma. Laboratory studies in rats confirmed that dietary glycine prevents tumor growth by inhibiting angiogenesis. In addition, glycine also plays a role in maintaining prostate health. A study found that glycine can help men reduce symptoms of enlarged prostate.
High-protein foods such as fish, meat, milk, and cheese are the best dietary sources of glycine. Glycine is a component of amino acid supplements. Although some people claim that taking this supplement causes nausea, no toxic effects of glycine have been found. People with kidney or liver disease are best advised to take glycine after consulting their doctor.
