Glycine is a non-essential amino acid, meaning your body can produce it on its own. However, it’s also found in foods like:
🥩 Meat & fish
🍖 Bone broth
🥚 Eggs
🫘 Legumes
🌱 Spinach & kale
Aside from supporting muscle growth and brain function, glycine plays a key role in regulating sleep, body temperature, and nervous system relaxation.
Glycine improves sleep in a unique way compared to other sleep aids. Instead of directly making you drowsy, it prepares your body for sleep by cooling it down and calming your mind. Here’s how:
✅ Lowers Body Temperature for Deeper Sleep – Glycine helps dilate blood vessels near the skin, allowing heat to escape. Since cooler body temperatures signal to your brain that it’s time for sleep, this process helps you fall asleep faster and stay asleep longer.
✅ Supports Relaxation & Stress Reduction – Glycine increases levels of GABA and serotonin, two neurotransmitters that calm the nervous system and promote relaxation.
✅ Enhances REM & Deep Sleep – Studies show glycine improves sleep quality by increasing the time spent in deep, restorative sleep, which helps you wake up feeling refreshed.
✅ Reduces Daytime Sleepiness – Unlike melatonin, which can sometimes cause grogginess, glycine helps you wake up feeling alert and energized.
✅ May Help with Insomnia & Poor Sleep Patterns – Some research suggests that glycine may help people who experience sleep disturbances, restless sleep, or difficulty staying asleep.
Glycine is available in several forms:
💊 Capsules or Tablets – Easy to take before bed.
💧 Powder – Can be mixed into water or tea (glycine has a slightly sweet taste).
🥩 Dietary Sources – Eating glycine-rich foods like bone broth, eggs, and fish can also help.
