What Is Glycine?
Glycine (L-Glycine) is an amino acid and the most abundant building block of collagen. Around 33% of the amino acid structure in collagen consists of glycine – no other protein in the human body contains as much of it.
As a non-essential amino acid, the body can synthesize glycine on its own. However, current nutritional science suggests that endogenous production often does not fully meet actual demand – particularly when collagen synthesis is high.
Glycine is an amino acid that serves as the primary building block of collagen and also acts as an inhibitory neurotransmitter in the central nervous system.
Glycine & Collagen: Why the Combination Matters
Collagen is the most abundant structural protein in the human body, found in skin, joints, bones, and connective tissue. Three amino acids are required in particularly large amounts for the body's own collagen synthesis:
-
Glycine (~33%)
- Proline (~12%)
- Hydroxyproline (~10%)
Those who supplement with collagen peptides or collagen hydrolysate may benefit from additional glycine to optimise the availability of collagen's most important building block.
Glycine & Sleep: What Nutritional Research Shows
Glycine is active in the central nervous system as an inhibitory neurotransmitter. Several human nutritional studies (including Bannai et al., 2012; Inagawa et al., 2006) have investigated the effect of evening glycine intake on subjective sleep quality.
Compliant formulation: As an amino acid, glycine contributes to normal protein synthesis. Research into glycine's role in the context of sleep is the subject of ongoing scientific investigation. Food supplements are not a substitute for medical treatment.
Glycine & Skin: Collagen From Within
Skin consists largely of collagen – and collagen consists of one-third glycine. An adequate supply of glycine is therefore a nutritional building block for the normal collagen structure of the skin.
In combination with Vitamin C – which, according to an EFSA-approved health claim, contributes to normal collagen formation for the normal function of the skin – glycine can be used as part of a holistic inside-out skincare routine.
Glycine & Joints: Structural Nutrition for Connective Tissue
Articular cartilage consists largely of type II collagen. As a direct amino acid building block of this collagen, glycine is an important nutrient for the normal structure of connective tissue.

FAQ – Frequently Asked Questions About Glycine Powder
What is glycine and what is it used for?
Glycine is an amino acid and the primary building block of collagen. It is used as a food supplement to nutritionally support the body's own collagen synthesis.
How much glycine per day is recommended?
Studies have frequently examined 3–5g daily. Our powder contains 5g per serving. Please do not exceed the recommended daily intake.
Is glycine vegan?
Yes. L-Glycine is produced fermentatively or synthetically and contains no animal-derived ingredients.
Can I combine glycine with collagen peptides?
Yes. Glycine and collagen peptides complement each other nutritionally, as glycine is the most abundant amino acid building block in collagen.
When should I take glycine?
Glycine can be taken at any time of day. Many users prefer taking it in the evening in warm water or herbal tea.
Does glycine have side effects?
Glycine is generally well tolerated at typical doses. If in doubt, we recommend consulting a doctor or nutritionist.
