Glycine for Sleep
If you’ve tried magnesium, melatonin, or herbal sleep teas and still feel wired at bedtime, you might be missing one simple supplement: glycine for sleep.
This naturally occurring amino acid doesn’t get as much attention as some of the big names in the sleep world — but it should. Glycine may help your body relax, regulate temperature, and ease you into deeper, more restorative sleep.
Here’s what glycine does, how to take it, and what the science says.
🧬 What Is Glycine for Sleep?
Glycine is a non-essential amino acid, meaning your body produces it on its own — but not always in optimal amounts. It plays a role in:
- Brain function
- Muscle performance
- Metabolic health
- Nervous system regulation
It’s also found in collagen, gelatin, and high-protein foods like meat, fish, and dairy.
When used as a glycine for sleep supplement, it helps relax the body without sedation.
😴 How Glycine Supports Better Sleep
Unlike sedatives or melatonin, glycine doesn’t make you feel sleepy — it prepares your body for rest. It works by:
- Lowering your core body temperature, a key trigger for sleep onset
- Activating calming neurotransmitters like GABA
- Supporting the circadian rhythm (your internal body clock)
This makes glycine for sleep helpful if you:
- Struggle to fall asleep
- Wake up frequently during the night
- Feel hot, restless, or anxious before bed
📚 What the Research Says
Clinical studies have shown that glycine may:
- Help people fall asleep faster
- Improve sleep quality and REM cycles
- Reduce daytime fatigue and brain fog
It’s also considered safe and well-tolerated, even at higher doses.

Yes — glycine is generally safe for long-term use when taken in appropriate doses. Because it doesn’t cause sedation or dependency, many people use glycine for sleep nightly with no adverse effects.
