Glycine is an amino acid, a building block for protein. It is not considered an "essential amino acid" because the body can make it from other chemicals. A typical diet contains about 2 grams of glycine daily. The primary sources are protein-rich foods including meat, fish, dairy, and legumes.
Glycine is used for treating schizophrenia, stroke, sleep problems, cystic fibrosis, 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 also be used to reduce the risk of psychosis. Other uses include cancer prevention and memory enhancement.
Some people apply glycine directly to the skin to treat leg ulcers and heal other wounds.
How does it work?
The body uses glycine to make proteins. Glycine is also involved in the transmission of chemical signals in the brain, so there is interest in trying it for schizophrenia and improving memory. Some researchers think glycine may have a role in cancer prevention because it seems to interfere with the blood supply needed by certain tumors.
Top Glycine Benefits
Muscle growth: glycine helps form new muscle as well as aids in muscle recovery. It's referred to as the anti-aging amino acid. It also helps prevent cartilage loss, which especially an issue in the aging population. Glycine is used in the synthesis of creatine, which is used as a direct fuel source in the body. Take glycine before and after your work out.
- Glycine helps repair and protect cartilage and joints (for joint pain), especially when you use it in combination with proline. You can get these things from collagen. It helps with the synthesis of protein.
- Glycine and proline improve digestion. They help rebuild the tissue lining your gut and prevent leaky gut issues.
- Glycine helps build the immune system, helps increase glutathione, which is the most powerful antioxidant.
- Glycine helps with your brain. It helps with electrolyte regulation.
- Glycine helps with sleep and increase growth hormone. This will help a lot if you're also doing regular work out.
Other Benefits and Uses of Glycine
Glycine is an amino acid that your body uses to create proteins, which it needs for the growth and maintenance of tissue and for making important substances, such as hormones and enzymes.
Your body naturally produces glycine from other amino acids, but it’s also found in protein-rich foods and available as a dietary supplement.
Along with being a component of protein, glycine has several other impressive health benefits.
Needed to Produce a Powerful Antioxidant
Glycine is one of three amino acids that your body uses to make glutathione, a powerful antioxidant that helps protect your cells against oxidative damage caused by free radicals, which are thought to underlie many diseases.
Without enough glycine, your body produces less glutathione, which could negatively affect how your body handles oxidative stress over time.
In addition, because glutathione levels naturally decline with age, ensuring that you get enough glycine as you get older may benefit your health.
Glycine helps your body make glutathione, an important antioxidant that protects your body against cell damage.
A Component of Creatine
Glycine is also one of three amino acids that your body uses to make a compound called creatine.
Creatine provides your muscles with energy to perform quick, short bursts of activity, such as weightlifting and sprinting.
When combined with resistance training, supplementing with creatine has been shown to increase muscle size, strength, and power.
It has also been studied for its beneficial effects on bone health, brain function and neurological conditions like Parkinson’s and Alzheimer’s disease.
While your body naturally creates creatine and it can be obtained through your diet, getting too little glycine may reduce how much you produce.
Glycine is a component of creatine, a compound that provides your muscles with energy and has been associated with other health benefits, such as improved bone health and brain function.
The Main Amino Acid in Collagen
Collagen is a structural protein that contains high amounts of glycine. In fact, every third to fourth amino acid in collagen is glycine.
Collagen is the most abundant protein in your body. It provides strength for your muscles, skin, cartilage, blood, bones, and ligaments.
Supplementing with collagen has been shown to benefit skin health, relieve joint pain and prevent bone loss.
Therefore, it’s important that you get enough glycine to support your body’s production of collagen.
Glycine is the most abundant amino acid in collagen, a structural protein that has several health benefits, including for your skin, joints, and bones. Luxxe White Enhanced Glutathione Food Supplement by Frontrow Enterprises contains 200mg of Glycine making it a good antiaging, antioxidant and skin lightening food supplement.
Glycine May Improve Sleep Quality
Many people struggle to get a good night’s rest, either because they have trouble falling or staying asleep.
While there are several ways you can improve your sleep quality, such as not drinking caffeinated beverages late in the day or avoiding bright screens a few hours before bedtime, glycine may also help.
This amino acid has a calming effect on your brain and could help you fall and stay asleep by lowering your core body temperature.
Research in people with sleep issues has shown that taking 3 grams of glycine before bed decreases how long it takes to fall asleep, enhances sleep quality, lessens daytime sleepiness and improves cognition.
For this reason, glycine may be a good alternative to prescription sleeping pills for improving sleep quality at night and tiredness during the day.
Glycine may promote sleep and enhance the quality of your sleep through its calming effects on the brain and its ability to lower core body temperature.
5. May Protect Your Liver From Alcohol-Induced Damage
Too much alcohol can have damaging effects on your body, especially your liver.
There are three primary types of alcohol-induced liver damage:
- Fatty liver: A buildup of fat inside your liver, increasing its size.
- Alcoholic hepatitis: Caused by inflammation of the liver resulting from long-term, excessive drinking.
- Alcoholic cirrhosis: The final phase of alcoholic liver disease, occurring when the liver cells are damaged and replaced by scar tissue.
- Interestingly, research suggests that glycine may reduce the harmful effects of alcohol on your liver by preventing inflammation.
It has been shown to reduce concentrations of alcohol in the blood of alcohol-fed rats by stimulating the metabolism of alcohol in the stomach rather than the liver, which prevented the development of fatty liver and alcoholic cirrhosis.
What’s more, glycine may also help reverse liver damage caused by excessive alcohol intake in animals. While moderate alcohol-induced liver damage can be reversed by abstaining from alcohol, glycine may improve the recovery process.
In a study in rats with alcohol-induced liver damage, the liver cell health returned to baseline 30% faster in a group fed a glycine-containing diet for two weeks compared to a control group.
Despite promising finds, studies on the effects of glycine on alcohol-induced liver damage are limited to animals and cannot be translated to humans.
Eating a diet with glycine decreases and reverses alcohol-induced liver injury in rats, but its effects in humans are unknown.
Glycine Protects Your Heart
Increasing evidence suggests that glycine offers protection against heart disease.
It prevents the accumulation of a compound that, in high amounts, has been linked to atherosclerosis, the hardening, and narrowing of the arteries.
This amino acid may also improve your body’s ability to use nitric oxide, an important molecule that increases blood flow and lowers blood pressure.
In an observational study in over 4,100 people with chest pains, higher levels of glycine were associated with a lower risk of heart disease and heart attacks at a 7.4-year follow-up.
After accounting for cholesterol-lowering medications, the researchers also observed a more favorable blood cholesterol profile in people who had higher glycine levels. What’s more, glycine has been found to reduce several risk factors of heart disease in rats fed a high-sugar diet.
Eating and drinking too much added sugar can raise blood pressure, increase levels of fat in your blood and promote dangerous fat gain around the belly — all of which can promote heart disease.
While encouraging, clinical studies on the effects of glycine on heart disease risk in humans are needed before it can be recommended (31Trusted Source).
Glycine may lower heart disease risk factors by preventing the build-up of a molecule associated with heart disease and by increasing your body’s ability to use nitric oxide.
Glycine in Luxxe White Aids People With Type 2 Diabetes
Type 2 diabetes may lead to low levels of glycine.
It’s a condition characterized by impaired insulin secretion and action, meaning your body doesn’t produce enough insulin or that it doesn’t respond properly to the insulin it makes.
Insulin decreases your blood sugar levels by signaling its uptake into cells for energy or storage. Interestingly, because glycine has been shown to increase insulin response in people without diabetes, it's suggested that glycine supplements may improve impaired insulin response in people with type 2 diabetes.
Higher levels of glycine are associated with a reduced risk of type 2 diabetes, even after accounting for other factors that are associated with the condition, such as lifestyle.
Therefore, people with type 2 diabetes may benefit from supplementing with glycine, though research is too preliminary to make any specific recommendations.
If you have type 2 diabetes, the best way to reduce your insulin resistance is through weight loss by means of diet and exercise.
Supplementing with glycine may improve impaired insulin action, a hallmark of type 2 diabetes. However, research to make any specific recommendations for its use in people with the condition is insufficient.
Glycine Protects Against Muscle Loss
Glycine may reduce muscle wasting, a condition that occurs with aging, malnutrition and when your body is under stress, such as with cancer or severe burns.
Muscle wasting leads to a harmful reduction in muscle mass and strength, which declines functional status and can complicate other potentially present diseases.
The amino acid leucine has been studied as a treatment for muscle wasting, as it strongly inhibits muscle breakdown and enhances muscle building. However, several changes in the body during muscle-wasting conditions impair the effectiveness of leucine for stimulating muscle growth.
Interestingly, in mice with muscle-wasting conditions, such as cancer, research has shown that glycine was able to stimulate muscle growth whereas leucine was not.
Therefore, glycine holds promise for improving health by protecting muscles from wasting during various wasting conditions.
Glycine may preserve muscle mass in wasting conditions, such as cancer, malnutrition, and burns, though more research in humans is needed.
Accordingly, you can boost your glycine intake by taking Luxxe White Enhanced Glutathione. This is likely more efficient, as glycine competes with other amino acids for absorption and is therefore absorbed less efficiently by itself than when it's bound to other amino acids, as in the case of collagen.
Is Luxxe White's Glycine Safe?
Supplementing with Luxxe White Enhanced Glutathione which contains 200mg Glycine is safe in appropriate amounts.
Studies have used up to 90 grams of glycine per day over several weeks without serious side effects. For comparison, the standard dose used in studies is about 3–5 grams per day.
The Bottom Line
Glycine is an amino acid with many impressive health benefits.
Your body needs glycine to make important compounds, such as glutathione, creatine, and collagen.
This amino acid may also protect your liver from alcohol-induced damage and improve sleep quality and heart health.
What’s more, glycine may also benefit people with type 2 diabetes and protect against muscle loss that occurs with muscle-wasting conditions.
You can increase your intake of this important nutrient by eating some meat products, and by taking at least 2 capsules of Luxxe White Enhanced Glutathione daily.
