🌱 What it is
Glycine is a simple amino acid the body makes naturally and also gets from protein-rich foods like meat, fish, and gelatin. Taken as a supplement before bed, it has been studied for its calming effect on sleep quality.
📜 Where it comes from
Glycine was first isolated from gelatin by a French chemist in the early 1800s, though foods rich in it, like bone broth and gelatin, had long featured in traditional diets across many cultures. Sleep researchers in the early 2000s began studying purified glycine taken before bed, building on this older nutritional familiarity. Its current use as a sleep supplement is a relatively recent development from that research.
✨ Why it's good for you
- May help some people fall asleep a bit faster
- Studied for subjective 'more rested' feelings after waking
- Generally well tolerated
- Inexpensive and easy to add to a bedtime routine
🙏 Begin with prayer
Prayer is the first remedy, not the last resort. Whether you are facing this yourself, caring for someone who is, or simply reading to understand — here is a simple prayer you are welcome to make your own, in your name or in theirs:
Heavenly Father, thank You for the rest my body needs and for simple gifts like glycine that may help quiet a restless night. I ask for Your wisdom as I use it, that it would support the sleep You designed for my healing and strength. Where sleep troubles run deeper, lead me also to wise medical care. I trust Your will above any remedy, and I rest tonight in Your peace. In Jesus' name, Amen.
“I will both lay me down in peace, and sleep: for thou, LORD, only makest me dwell in safety.”— Psalm 4:8
🥄 How to use it
Most studies use about 3 grams of glycine powder or capsules dissolved in water, taken roughly 30-60 minutes before bedtime. It has a mildly sweet taste and dissolves easily. Give it several consistent nights before judging whether it helps.
How much: About 3 grams before bed, per typical study protocols... start lower and see how you respond.
Why it works: Researchers believe glycine may slightly lower core body temperature and act on calming neurotransmitter pathways, though the exact mechanism for sleep isn't fully settled.
⚠️ Cautions
- Persistent insomnia lasting weeks deserves a conversation with a doctor... this is a comfort aid, not a treatment for underlying sleep disorders like sleep apnea.
- May cause mild stomach upset in some people.
- Not a substitute for good sleep hygiene (consistent bedtime, dark room, limited screens).
