Glycine and melatonin are two popular supplements used to improve sleep quality. Both have been studied extensively, with research showing that they may be effective in helping people fall asleep faster and stay asleep longer.
However, while each has its unique benefits, there are some important differences and similarities that must be considered when deciding which supplement to take.
For example melatonin tends to be better at improving sleep quality, deep sleep, and helping with jet lag. Whilst glycine may help reduce stress and promote relaxation, which in turn can make it easier to get to sleep.
But that’s just scratching the surface when it comes to the similarities and differences between glycine and melatonin and the science behind them. Luckily we delve into all of that and more right here.

Glycine vs Melatonin: which one is better for sleep?
Both glycine and melatonin are naturally occurring compounds found in the body, but they have very different effects on sleep.
Glycine is an amino acid that occurs naturally in the body and can be found in certain foods like pork, beef, turkey, fish, dairy products, soybeans and legumes.
It plays a role in various physiological processes related to sleep, including helping to regulate the hormone cortisol and promoting relaxation. Therefore, glycine has been studied for its potential to improve sleep quality and reduce daytime fatigue.
Fundamentally Glycine is an amino acid that acts as a neurotransmitter in the brain, helping to regulate mood and stress levels.
Glycine also helps to stimulate the natural production of GABA (gamma-aminobutyric acid), a neurotransmitter that has a calming effect on the body. It is a supplement that helps reduce stress and improve sleep quality.
Melatonin is a hormone produced in the brain’s pineal gland, which regulates our internal clock and helps us fall asleep. It also helps to regulate circadian rhythms, helping to ensure that our bodies and minds are in sync with the natural day-night cycle.
As a supplement, melatonin can help to reset our body clock and adjust to changes in time zones or jet lag.
So which one is better for sleep?
Well both glycine and melatonin have been proven to be effective at helping people fall asleep faster. Still, research has found that melatonin promotes deep and restorative sleep more effectively. On the other hand, glycine can help to reduce stress levels and make sleeping easier to come by, but it won’t necessarily provide the same deep sleep as melatonin.
Ultimately, it’s up to you to decide which works best for you. Melatonin might be better if you seek more profound, more restorative sleep. However, if you’re looking for a way to wind down and get better quality sleep, then glycine may be your best bet.
No matter which one you choose, take it as directed by your doctor or pharmacist and only use it as needed.
