Centenarius Nutrition is proud to present our premium Glycine supplement. Pharmaceutical grade in quality with source materials derived exclusively from Japan.

With a key role in so many bodily processes from brain function to muscle growth and sleep, glycine is an amino acid whereby considered “non-essential,” while being truly “essential” to fuel your body with everything it needs to perform. Glycine is the most abundant amino acid in the body.



In the central nervous system, Glycine functions as an inhibitory (calming) neurotransmitter. Glycine slows down the firing of neurons reducing anxiety and protecting the brain from overstimulation. These are all desirable qualities to support deep, refreshing sleep.

Using the gold standard measure of sleep, polysomnography (PSG), research has shown that 3g of glycine ingested before bed reduces the time taken to fall asleep (known as sleep latency) and helps people get into restorative, growth-inducing, recovery-promoting slow-wave sleep (SWS) quicker.



Both animal and human studies show that N-methyl-D-aspartate receptor function is involved in learning and memory. Glycine binds to a modulatory site on the NMDA receptor complex and, by increasing its function, may improve memory and learning.

Glycine accomplishes several functions as a transmitter in the central nervous system (CNS). As an inhibitory neurotransmitter, it participates in the processing of motor and sensory information that permits movementand vision.

In addition, glycine has shown promising effects for managing symptoms of depression, anxiety, obsessive compulsive disorder (OCD), and addiction.



In a science experiment studied amongst mice and their muscle mass, 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 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.



Glycine is well-known for its ability to regulate your blood sugar levels and stimulate insulin secretion in humans. Despite being a sweetener, glycine has been researched for its ability to lower blood sugar levels and risk of obesity.

In addition, glycine supplements may help reduce the risk of a heart attack.



Glycine is involved in digestion, specifically in the breakdown of fatty acids in foods. It promotes rebuilding tissue that lines the digestive tract, keeping food particles and bacteria inside the gut where they belong, rather than allowing tiny openings to form that pass particles to the bloodstream, where they trigger inflammation. It has also been shown to facilitate the rate of stomach acid secretion.

Glycine is crucial for maintaining the intestinal wall and its mucosa.  If you have a disorder such as SIBO or Leaky Gut in which your gut is damaged, then glycine can help heal your gut lining.



Glycine plays a key role in phase II liver detoxification directly effecting toxin elimination, and by increasing the level of glutathione,  a substance your liver uses to protect your body's cells and tissues from free radical damage.

Glycine works in your body to detoxify toxic chemicals like toluene, which is released from the paint in your house. 

What’s more, glycine may also protect your liver from Alcohol-Induced damage.



Glycine makes up 1/3 of the amino acid content in collagen and elastin. These substances are essential to maintain the integrity and strength of skin and bone.

Glycine is an important, natural component of collagen, a protein that forms part of the body’s connective tissues like the tendons, ligaments, skin, cartilage, bone, and blood vessels. These areas tend to undergo constant physical stress thus eating more foods and supplements containing glycine can keep collagen in good shape, a sign of healthy aging.


*Glycine has a mildly sweet taste and can be used as a sweetener. It is one of the most palatable supplements.
