The formula

L-glycine

Fundamental non-essential amino acid in the synthesis of bodily proteins

2.5 g
Pure Glycine
Glycine is the simplest of all amino acids, made up of a single carbon atom bound to an amine group. Naturally present in the body, it plays a key structural and functional role.
In the body, glycine acts as an inhibitory neurotransmitter in the central nervous system, particularly in the spinal cord and brainstem. It also plays a role in the synthesis of collagen, glutathione, and heme (iron transport).

In the body, glycine acts as an inhibitory neurotransmitter in the central nervous system, particularly in the spinal cord and brainstem. It also plays a role in the synthesis of collagen, glutathione, and heme (iron transport).

The 2.5 g dosage corresponds to a physiologically active dose, similar to that used in clinical studies on sleep quality (Yamadera et al., 2007, Sleep and Biological Rhythms).

Our commitments

  • Origin

    Researched and packaged in our Swiss laboratory, in Valais.

  • Formulation

    Pure crystallised glycine, no additives or preservatives

  • Quality

    Tested and validated by ISO/IEC 17025:2017 accredited Swiss labs

Exelis Glycine is a crystallised glycine of pure quality, designed to meet the highest Swiss standards. Produced through a rigorous purification process, it delivers 100% purity, with no additives or preservatives. This versatile amino acid plays an essential role in collagen formation, tissue regeneration, nervous relaxation, and sleep quality.

Glycine is naturally present in the body, but dietary intake is often not enough to cover the many metabolic functions it supports. Thanks to its crystallised powder form, which is mildly sweet and perfectly soluble, Exelis Pure Glycine is a simple, effective and pleasant dietary supplement to build into a balanced nutrition routine.

This article covers everything you need to know about this simplest of amino acids, its many health benefits, and why Exelis offers one of the purest crystallised glycines on the market today.

What is glycine and why is it essential to the body?

What is glycine?
Glycine is a non-essential amino acid, meaning it can be synthesised naturally by the body. Yet physiological needs often exceed internal production capacity, leading to a glycine shortfall in many people.

Crystallised glycine forms an integral part of almost all proteins in the body, and in particular of collagen, of which it makes up roughly one third of the amino acids. It also takes part in the production of glutathione, a powerful antioxidant responsible for protecting cells against free radicals.

Beyond its structural roles, this amino acid helps regulate the brain's neurotransmitters, supporting relaxation and mental clarity. Glycine is found throughout the human body, and supplementation can help support overall health across muscular, joint, cognitive and metabolic dimensions.

Why is glycine a unique amino acid?

Glycine holds a very particular place among amino acids. It is the smallest amino acid and one of the oldest from an evolutionary standpoint. As a result, it helps cover many vital functions in the body.

As a glycine base for building collagen, glutathione, creatine and other essential molecules, it is involved in construction, repair and cellular protection alike. Glycine is also among the substances that are naturally mildly sweet, making its consumption in powder form particularly pleasant.

This non-essential amino acid also supports liver detoxification and plays a key role in stabilising blood sugar. In short, glycine as a supplement can contribute to both tissue building and metabolic regulation, making it a valuable ally for a healthy lifestyle.

What is glycine's role in collagen synthesis?

Glycine is indispensable to collagen synthesis, the most abundant protein in the human body. Without glycine, producing functional, stable collagen is simply not possible.

Collagen forms the structural framework of tendons, ligaments, skin, cartilage and muscles. Yet with age or insufficient intake, natural collagen production declines. That is where glycine supplementation makes real sense.

By supporting collagen synthesis, Exelis Glycine supports the regeneration of connective tissues and improves skin elasticity. It is also a key amino acid for healing and muscular recovery after intense physical effort.
Athletes, as well as those wishing to preserve their mobility and the health of their tendons, benefit genuinely from a regular glycine course.

Glycine and sleep quality: a demonstrated link

One of the many benefits of glycine concerns sleep quality. Taken before bedtime, glycine supports relaxation, reduces core body temperature and improves sleep depth.

Several clinical studies show that glycine intake before bedtime significantly improves sleep quality without causing daytime drowsiness. Crystallised glycine is among the safest natural solutions for restoring a stable circadian rhythm and falling asleep more quickly.

In addition, this amino acid contributes to the regulation of the central nervous system. It acts as an inhibitory neurotransmitter, helping to ease stress and balance neuronal activity. In short, glycine supports mental relaxation while encouraging restorative sleep, with no side effects.

How does glycine act on tendons, muscles and joints?

Glycine is essential to the regeneration of support tissues such as tendons and muscles. By supporting collagen production, it helps maintain the strength and flexibility of joints, while supporting muscular performance.

In athletes, glycine supplementation helps improve recovery and reduce muscle soreness. Combined with a varied and balanced diet, it can even accelerate the repair of exercise-related micro-tears in muscle tissue.

Since tendons are made up primarily of collagen, a sufficient intake of pure glycine contributes to their strength and elasticity. This makes glycine as a dietary supplement particularly useful for preventing injuries and preserving joint mobility over the long term.

Glycine and creatine: a complementary pair

Often overlooked, glycine is one of the direct precursors of creatine, a molecule essential to muscular energy production. By providing glycine, you indirectly support the natural synthesis of creatine.

This unique metabolic role explains why glycine plays such an important part in muscular performance and energy recovery. It supports the metabolism of muscle cells, while acting as a buffer against the acidity produced during intense effort.

Combined with a sufficient protein intake, crystallised glycine thus supports better endurance, reduced fatigue and an overall improvement in physical tone.

What daily glycine dosage is recommended?

The optimal dosage depends on your needs and goals.
For general support of collagen and the nervous system, 2.5 to 5 g of glycine per day is sufficient.
For a glycine course more targeted at tissue regeneration, muscular recovery or sleep, up to 10 g per day is recommended.

Glycine can be taken at any time of day, but consuming it before bedtime remains the best choice to benefit from its relaxing effects.
For pregnant or breastfeeding women, or those undergoing medical treatment, it is advisable to seek the advice of a healthcare professional before beginning glycine supplementation.

Frequently asked questions

How does Glycine actually work in the body?

Glycine is a core amino acid that makes up around 35% of the collagen in your body. It plays a role in protein synthesis and acts as an inhibitory neurotransmitter in your central nervous system. That is why it naturally supports your overall well-being — especially in the evening.

Can this cause digestive issues?

Pure crystallised glycine is very well tolerated by the body. Its mildly sweet taste and easy dissolution make it a pleasant supplement to take. Unlike some supplements, it generally causes no digestive discomfort, even when taken in the evening.

Can I take it alongside collagen?

Yes — in fact, it is the ideal combination. Collagen provides a broad spectrum of amino acids for the joints and skin, while glycine supports collagen synthesis from within and also acts on sleep.

How long before I start noticing results?

For sleep, the first effects are often felt within the first week. For joints and recovery, allow 4 to 6 weeks of regular use.

Why supplement if the body already makes it naturally?

Modern diets provide very little glycine, unless you regularly eat bone broths, offal, or cartilage. Beyond a certain level of physical activity or stress, your needs exceed what the body can produce on its own.
