Glycine is the smallest amino acid molecule found in connective tissue. It helps in the synthesis of many amino acids, boosting more energy to the body. It is essential for the functioning of the central nervous system and brain as well as in building DNA, RNA, muscles, and skin. Glycine is a precursor to the production of Glutathione that helps brighten the skin color. Also, it is the main structure of collagen that keeps the skin moist and tight. It can be found in high-protein foods such as fish, meat, legumes, milk, and cheese.
Glycine has many health benefits :
- White skin : Glycine is a precursor to the production of Glutathione, which is an antioxidant that helps protect cells from the destruction of free radicals and inhibit the enzyme Tyrosinase which is the initiator of melanin production, thereby helping the skin color to be brighter and more radiant.
- Moisturized, tight skin : The production of collagen requires 4 essential amino acids which are glycine, proline, arginine, and glutamine. Collagen plays a very important role in enhancing the water in the skin cells and maintaining the skin elasticity which resulting in healthy, elastic, and moist skin. Therefore, glycine is the main structure of collagen that helps stimulate the creation of collagen in the inner skin, helping skin and organs in moisturizing, elasticity, and tight.
- Antioxidant : Glycine is one of the precursors in the production of glutathione which is an antioxidant that prevent cells from deteriorating or being attacked by free radical oxidation, protecting the skin from aging and cell mutations. Also, it helps slow down the aging of the skin, boost immunity system and reduce inflammation and damage from sunlight, UV rays and free radical.
- Reduce the risk of type 2 diabetes : Many nutritional doctors today use glycine to treat hypoglycemia. Glycine stimulates the secretion of glucagon, which breaks down glycogen into sugar into the bloodstream. It helps convert glucose into energy. It helps maintain blood sugar levels and reduce the risk of type 2 diabetes.
- Protects joints and bones : Glycine is the main amino acid in collagen, with the composition of approximately 1/3. Collagen is the most abundant protein in the body that helps joints to be flexible and durable and strengthens muscles, skin, joints, and bones. Also, it helps reduces the deterioration of collagen in the joints and relieve joint pain and prevent bone loss. Therefore, it is important that you get enough glycine to support collagen production in the body.
- Improve sleep quality : The good quality sleep is correlated with the body temperature. This amino acid has a calming effect on your brain. It relieves stress and anxiety and can help you fall asleep more easily by lowering our body's core temperature, which is important for us to sleep well. Research in people with sleep problems shows that taking 3 grams of glycine at bedtime reduces the time taking to fall asleep, improves sleep quality and reduces daytime sleepiness.
- Protects the Heart : Evidence show that glycine protects against heart disease and prevents the buildup of compounds linked to atherosclerosis, narrowed blood vessel. It enhances the body's ability to use nitric oxide, an important molecule that improves blood flow and lowers blood pressure. A study of more than 4,100 people with chest pain, with 7.4-year follow-up, found that a higher glycine level is correlated with a lower risk of heart disease and heart attack. Researcher found lower cholesterol in blood with those who have higher glycine.
- Feel refreshed and energized : Glycine is a component of creatine which helps to build muscles, increases durability, and slows down the symptoms of fatigue. It gives your muscles the energy to do short and intense activities like weightlifting and running. If the body receives the right amount of glycine, it will help you feel refreshed and energized, as well as boost your mental health.
- Good for the nervous system and brain : Glycine is important for the nervous system and brain. It helps control the functioning of the nervous system of the body by adjusting the level of electrolyte balance. Glycine is used to treat schizophrenia and memory disorders. The research found that Glycine improves memory in people who suffer from sleep problems, schizophrenia, Parkinson's disease, Alzheimer’s disease, and Jet Lag disease. It has also been used to treat manic depression and hyperactivity and prevent symptoms of epilepsy and ischemic strokes.
- Prevents muscle loss : Glycine reduces muscle loos, a condition that occurs with age and under stress, such as cancer or severe burns. Loss of muscle can lead to a dangerous decrease in muscle mass and strength, which reduces function and can lead to other potential ailments in the body. Glycine inhibits muscle breakdown and enhances muscle building. It is effective in the treatment of muscle atrophy.
- Increase Growth Hormone : Glycine plays an important role in the production of growth hormones in the body. It is an amino acid that is used to build proteins that are needed for growth, tissue maintenance and important substance production, such as hormones and enzymes. Glycine is used during the synthesis of creatinine which delivers energy to heal muscles damaged by exercise and rebuild stronger muscles. Therefore, if the body is deficient in glycine, the damaged tissue will not be repaired, and wound will be difficult to heal.
