Powder glycine | Profeel Life

Q: 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.

Q: 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.

Q: 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.

Q: 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.

Q: 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.

The amino acid that repairs from within

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).
