Support Deeper Sleep and Healthy Collagen Production with Premium USP-Grade Glycine
Glycine is the simplest and one of the most abundant amino acids in the human body. It plays a key role in collagen formation, supports restful sleep, and helps maintain healthy nervous system function. Many people take glycine in the evening because of its calming properties and its ability to promote deeper, more restorative sleep.
Our Glycine Powder is USP Grade and sourced from the USA. It is highly pure (99.9%) and contains no fillers or additives. This clean, single-ingredient powder is ideal for those who want to support healthy sleep, collagen production, muscle recovery, and overall metabolic health as part of a balanced diet.

Glycine is the smallest and one of the most abundant amino acids in the human body. It functions as both a building block for proteins (especially collagen) and as an inhibitory neurotransmitter in the central nervous system.
Key Research Findings:
- Glycine and sleep quality
Inagawa, K. et al. (2006). Subjective effects of glycine ingestion before bedtime on sleep quality. Sleep and Biological Rhythms, 4(1), 75–77.
This study found that glycine taken before bedtime improved subjective sleep quality and reduced daytime fatigue.
- Glycine and collagen synthesis
de Paz-Lugo, P. et al. (2018). High glycine concentration increases collagen synthesis by articular chondrocytes. Connective Tissue Research, 59(5), 458–464.
Research has shown that glycine availability can influence collagen production in the body.
- Glycine as an inhibitory neurotransmitter
Betz, H. & Laube, B. (2006). Glycine receptors: recent insights into their structural organization and functional diversity. Journal of Neurochemistry, 97(6), 1600–1610.
Glycine acts as an important inhibitory neurotransmitter, helping to regulate nerve activity in the brain and spinal cord.
- Glycine and metabolic health
Yan-Do, R. & MacDonald, P.E. (2017). Impaired “Glycine”-minergic signaling in the nucleus tractus solitarii of spontaneously hypertensive rats. Hypertension, 69(5), 869–877.
Studies have explored glycine’s role in metabolic regulation and blood pressure control.
- Glycine and neuroprotection
Wang, W. et al. (2016). Glycine and N-acetylcysteine supplementation improves multiple cellular functions in older adults. JCI Insight, 1(15), e85915.
Research has investigated glycine’s potential protective effects on cellular health and aging.
- Glycine and anti-inflammatory effects
Zhong, Z. et al. (2003). Glycine prevents apoptosis and improves survival in models of shock and sepsis. Critical Care Medicine, 31(2), 528–536.
Animal studies have shown glycine may help reduce inflammation and protect against certain types of cellular stress.
Metabolic Research Perspectives:
Within bioenergetic and metabolic research traditions, glycine is valued for its dual role in structural integrity (via collagen) and nervous system regulation. Its ability to act as an inhibitory neurotransmitter is often highlighted for supporting calm, restorative sleep, and balanced nervous system function. Additionally, its contribution to collagen formation is recognized as important for maintaining tissue resilience and overall structural health.
From a low toxin perspective, glycine is particularly valuable because it serves as a key building block for glutathione — the body’s primary antioxidant and detoxification molecule. By supporting glutathione production, glycine helps the liver more effectively neutralize and eliminate toxins and metabolic waste. Additionally, this USP-grade Glycine is offered as a clean, single-ingredient powder with no fillers or unnecessary additives, aligning with those seeking to minimize their overall toxic burden while supporting the body’s natural detoxification and recovery processes.
