The formula

L-glycine

Amino acid that is non-essential yet fundamental in the synthesis of body proteins

2,5 g
Glycine pure
Glycine is the simplest amino acid, composed of a single carbon atom linked to an amine group. Naturally present in the body, it plays an essential structural and functional role.
In the body, glycine acts as an inhibitory neurotransmitter in the central nervous system, particularly in the spinal cord and brain stem. It also participates 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 brain stem. It also participates in the synthesis of collagen, glutathione and heme (iron transport).

The dosage of 2.5 g 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

    Developed and packaged in our Swiss laboratory, in Valais

Glycine Exelis is a pure quality crystallized glycine, designed to meet the highest Swiss standards. Produced through a rigorous purification process, it offers 100% purity, without additives or preservatives. This versatile amino acid plays an essential role in collagen formation, tissue regeneration, nervous system relaxation, and sleep quality.

Glycine is naturally present in our body, but its intake through diet is often insufficient to support numerous functions in our metabolism. Thanks to its crystallized powder form, which is slightly sweet and perfectly soluble, Pure Glycine Exelis is a simple, effective and pleasant dietary supplement to incorporate into a balanced nutrition routine.

This article details everything you need to know about this simplest amino acid, its numerous health benefits, and the reasons why Exelis now offers one of the purest crystallized glycines on the market.

What is glycine and why is it essential for our body?

What is glycine?
Glycine is a non-essential amino acid, meaning it can be synthesized naturally by our body. However, physiological needs often exceed the internal production capacity, resulting in a glycine deficiency in many people.

Crystallized glycine is an integral part of almost all proteins in the body, particularly collagen, where it makes up about one-third of all amino acids. It also contributes to the production of glutathione, a powerful antioxidant responsible for protecting cells against free radicals.

Beyond its structural functions, this amino acid helps regulate brain neurotransmitters, promoting relaxation and mental clarity. Glycine is present throughout the human body, and supplementation can help support overall health on muscular, joint, cognitive, and metabolic levels.

Why is glycine a unique amino acid?

Glycine plays a very special role among amino acids. It is the smallest amino acid and one of the oldest from an evolutionary standpoint. As such, it helps support numerous vital functions in the body.

As a glycine base for the production of collagen, glutathione, creatine and other essential molecules, it is involved in cell building, repair, and protection. Glycine is also naturally slightly sweet, making its consumption in powder form particularly pleasant.

This non-essential amino acid also supports liver detoxification and plays a key role in stabilizing blood sugar levels. In other words, glycine is a supplement that can participate in 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 essential for collagen synthesis, the most abundant protein in the human body. Without glycine, it is simply impossible to produce functional and stable collagen.

Collagen forms the structural framework of tendons, ligaments, skin, cartilage, and muscles. With age or insufficient intake, natural collagen production decreases. This is where glycine supplementation becomes particularly valuable.

By promoting collagen synthesis, Exelis glycine supports the regeneration of tissues and improves skin elasticity. It is also an essential amino acid for healing and muscle recovery after intense physical activity.
Athletes, as well as people wishing to preserve their mobility and tendon health, gain real benefits from regular glycine supplementation.

Glycine and sleep quality: a proven connection

One of the numerous benefits of glycine relates to sleep quality. Taken before bedtime, glycine promotes relaxation, reduces body temperature, and improves sleep depth.

Several clinical studies show that glycine intake before bedtime significantly improves sleep quality without causing daytime drowsiness. Crystallized glycine is one of the safest natural solutions for restoring a stable circadian rhythm and achieving faster sleep onset.

Additionally, this amino acid helps regulate the central nervous system. It acts as an inhibitory neurotransmitter, helping to reduce stress and balance neuronal activity. In short, glycine supports mental relaxation while promoting restorative sleep, without side effects.

How does glycine act on tendons, muscles, and joints?

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

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

Since tendons are composed mainly of collagen, 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 duo

Often overlooked, glycine is one of the direct precursors of creatine, an essential molecule for muscle energy production. By providing glycine, you indirectly promote the natural synthesis of creatine.

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

Combined with sufficient protein intake, crystallized glycine promotes better endurance, reduced fatigue, and an overall improvement in physical tone.

What is the recommended daily dosage of glycine?

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 more targeted glycine supplementation focused on tissue regeneration, muscle recovery, or sleep, up to 10 g per day is recommended.

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

Frequently asked questions

How does Glycine work in the body exactly?

Glycine is a fundamental amino acid that makes up around 35% of the collagen composition in our body. It helps with protein synthesis and acts as an inhibitory neurotransmitter in your central nervous system. That's why it naturally contributes to our overall well-being, especially in the evening.

Can this cause digestive issues?

Pure crystallized glycine is very well tolerated by the body. Its slightly sweet taste and easy dissolution make it a pleasant supplement to consume. Unlike some supplements, it generally doesn't cause digestive discomfort, even when taken in the evening.

Can I take this with collagen?

Yes, it's actually the perfect combination! Collagen provides a broad spectrum of amino acids for joints and skin, while glycine enhances collagen synthesis from within and additionally helps with sleep.

How long until I notice results?

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

Why take supplements if the body produces them naturally?

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