Glycine is an amino acid that has been linked to a range of health benefits, including better sleep. It is one of the most important protein-fuelling amino acids in the body, supporting muscle strength, bone health, metabolism, brain function, and sleep. While the body can produce glycine on its own, many people may turn to protein-rich foods or supplements to increase their glycine levels. Research has shown that taking glycine before bed helps people reach deep sleep more quickly, spend more time in REM sleep, and wake up feeling more refreshed.
| Characteristics | Values |
|---|---|
| How it works | Glycine increases blood flow to the body's extremities, reducing core body temperature, which is key to the body's progression into sleep. |
| Glycine also increases serotonin production, encouraging healthy sleep cycles by facilitating melatonin synthesis. | |
| It is an inhibitory neurotransmitter, blocking messages from being passed to the next brain cell, which induces sleep and calms the mind. | |
| Forms | Glycine is available as a dietary supplement in the form of capsules, pills, and powder. |
| It can also be consumed through protein-rich food sources, especially seafood such as scallops and shrimp. | |
| Dosage | A 3-gram dose of glycine has been studied and found to not cause any side effects. |
| A 3-gram dose before bedtime has also been found to improve sleep quality and reduce sleepiness during the day. | |
| Benefits | Glycine helps the body reach deep sleep more quickly and improves overall sleep quality. |
| It supports physical growth and health, including skin and hair health, and boosts immunity. | |
| It also supports metabolic health, healthy protein synthesis, and tissue health, and helps fight oxidative stress. | |
| Glycine may be a non-habit-forming option for those seeking to enhance their sleep. |

Glycine is an amino acid that helps the body reach deep sleep
Glycine is also sold as a dietary supplement and is marketed as a treatment for sleep problems like insomnia. It is available in the form of capsules and pills, as well as a powder that can be dissolved in water and added to tea, coffee, yogurt, oatmeal, soups, or smoothies. Research has shown that taking glycine before bedtime helps the body reach deep sleep more quickly and improves overall sleep quality.
One way glycine accomplishes this is by increasing blood flow to the body's extremities, which reduces core body temperature. A slight drop in body temperature is a key part of the body's physical progression into sleep. Studies have shown that glycine supplementation triggers a drop in body temperature, helping people fall asleep faster and spend more time in REM sleep.
Additionally, glycine works to stabilize sleep rhythms, which can help improve sleep quality and enhance daytime alertness and cognitive performance. It also increases serotonin production, which encourages healthy sleep cycles by facilitating the synthesis of melatonin, the sleep hormone.

It increases blood flow to the body's extremities, reducing core body temperature
The amino acid glycine is naturally produced in the human body and has a wide range of health benefits. It is involved in creating proteins, including collagen, which is essential for the growth and maintenance of connective tissues, bones, cartilage, and blood vessels. It also plays a role in hormone, antioxidant, and enzyme production.
Glycine has been found to promote good quality sleep, helping people to fall asleep faster and spend more time in REM sleep. It does this in several ways, one of which is by increasing blood flow to the body's extremities, thereby reducing core body temperature.
The body's temperature fluctuates throughout the day, and a slight drop in body temperature is a key part of the body's progression into sleep. Glycine triggers a drop in body temperature, helping people to fall asleep more quickly. A study on rats found that glycine administration led to increased peripheral blood flow, and another study showed that glycine triggered a drop in body temperature while helping people fall asleep faster and spend more time in deep, slow-wave sleep.
The Sleep Foundation suggests that an optimal temperature for quality sleep is approximately 65 degrees Fahrenheit. Keeping the room temperature slightly cool can help induce sleep by keeping the body temperature in the right range for bedtime.

It can be taken as a supplement or found in food sources
Glycine is available as a dietary supplement in the form of capsules, pills, and powder. The powder form can be added to tea, coffee, yoghurt, oatmeal, soups, or smoothies. It is also naturally produced in the body and can be found in many foods, especially seafood such as scallops and shrimp. It is one of the 11 amino acids synthesized in the human body and is used to create proteins, including collagen, which is essential for the growth and maintenance of connective tissues, bones, cartilage, and blood vessels. It also plays a role in hormone, antioxidant, and enzyme production.
Glycine is an inhibitory neurotransmitter, which means it blocks messages from being passed along to the next brain cell. These types of neurotransmitters are generally responsible for inducing sleep and calming the mind. It also works to increase blood flow to the body's extremities, which reduces core body temperature. A slight drop in body temperature is a key part of the body's physical progression into sleep.
Supplemental glycine has been shown to improve both memory and attention in young adults, and scientists are actively investigating its use in the treatment of neurodegenerative disorders such as Alzheimer's disease. It also functions as an antioxidant, helping to trap and contain damaged cells that can cause disease. Higher levels of glycine have been associated with a lower risk of heart attack, and there is some evidence that it may help protect against high blood pressure.

It may be a non-habit-forming option for those seeking to enhance their sleep
Glycine is an amino acid that is naturally produced in the human body and has many health benefits. It is involved in creating proteins, including collagen, which is essential for connective tissues, bones, cartilage, and blood vessels. It also plays a role in hormone, antioxidant, and enzyme production.
As a supplement, glycine has been shown to improve sleep quality and reduce sleepiness during the day. It helps individuals fall asleep faster and enhances their daytime alertness and cognitive performance. Furthermore, it does not cause grogginess or fatigue during the day, unlike many pharmaceutical sleep aids.
Glycine is available as a dietary supplement in capsule, pill, or powder form. The powder can be added to various foods and drinks, such as tea, coffee, yogurt, oatmeal, soups, or smoothies.
While the exact mechanism of glycine's effect on sleep is still being studied, it appears to influence the body's systems and processes, including cardiovascular, cognitive, and metabolic functions. It also works by increasing blood flow to the body's extremities, which, in turn, reduces core body temperature. This reduction in body temperature is a key factor in the body's transition to sleep.
Due to its role in promoting sleep and its lack of known side effects, glycine may be a non-habit-forming option for those seeking to enhance their sleep quality and overall well-being. However, more research is needed to fully establish its efficacy and long-term effects.
