Glycine is an amino acid that is produced by the liver and is necessary for protein metabolism. It can also be found in some foods, such as meat, fish, and vegetables, and in supplements. This amino acid plays an important role in regulating sleep. Glycine helps reduce brain activity and increases the activity of the neurotransmitter GABA, which facilitates sleep. In addition, it helps reduce the activity of neurons that cause anxiety.

Glycine is an amino acid that plays an important role in the metabolism and functioning of the body, it is also involved in the synthesis of other compounds, such as creatine. The sleep benefits of glycine are well established. Glycine is an amino acid that acts as an inhibitory neurotransmitter in the brain. This means that glycine can help decrease brain activity and help induce sleep. In addition, glycine can also help decrease anxiety and depression, which can be contributing factors to insomnia. This amino acid can also help decrease stress and fatigue, which can influence rest.

Sleep is a very important physiological process, as it regulates the body's functions. It is responsible for promoting / facilitating energy conservation, synthesis and secretion of hormones and proteins, learning and memory through brain changes. Sleep is mainly driven by the circadian cycle, which involves exposure to light, hormones such as melatonin, and hypothalamic activity. The compounds that help regulate sleep work in different pathways, they can facilitate the process of falling asleep, increase the duration of continuous sleep or improve the quality of sleep.
Sleep latency is the time it takes between being awake and actually falling asleep. More importantly than many think, sleep latency is linked to and impacted by the stages of sleep. Fortunately there are natural solutions to improve latency and quality of nightly rest.
