Sleep isn’t just a nightly ritual—it's the foundation of recovery, mental clarity, and long-term health. Yet, for millions of people, quality rest feels just out of reach. While melatonin often gets the spotlight, a lesser-known group of natural compounds may be the missing link: amino acids. Specifically, glycine, tryptophan, and GABA have gained traction in sleep research for their unique effects on relaxation and neurotransmitter function.
These amino acids don’t simply knock you out—they work with your body's internal systems to promote deeper, more restorative sleep. Whether you’re dealing with trouble falling asleep, frequent wakeups, or poor sleep quality, understanding the science behind these amino acids can help you create a more effective, natural approach to sleep health. Let's explore how glycine, tryptophan, and GABA could help you finally get the rest your body craves.
