Glycine
sweet amino acid for sleep and collagen synthesis
Administration
Categories
Also Known As
Aminoethanoic acid
Overview
Glycine is the smallest and simplest amino acid in the body. While it is non-essential, modern diets lack the connective tissues (like bone broth and organ meats) that provide abundant glycine. It makes up one-third of collagen protein and acts as an inhibitory neurotransmitter in the brain. Supplementation is highly effective for improving sleep quality and balancing the methionine load from high-muscle meat diets.
Safety & Considerations
No significant safety concerns for healthy adults at recommended doses.

Benefits
- Lowers core body temperature to induce deep sleep
- Enhances collagen production for skin and joints
- Reduces daytime fatigue and sleepiness
- Helps regulate blood sugar levels
- Supports the production of the master antioxidant glutathione
How It Works
In the central nervous system, glycine binds to its own receptors and NMDA receptors to exert a calming, inhibitory effect. Peripherally, it facilitates vasodilation, dropping core body temperature, which is a physiological requirement for initiating sleep.
Common Uses
- Improving sleep architecture
- Collagen and joint support
- Anti-inflammatory diets
- Longevity protocols
Typical Protocol
3g to 5g taken 30-60 minutes before bed. Has a naturally sweet taste and mixes easily in tea or water.
