L-theanine is an amino acid that is commonly found in green tea. It has been studied for its potential benefits for sleeplessness, as it has been shown to have a calming effect on the mind and body without causing drowsiness. In this article, we will explore the benefits of L-theanine for sleeplessness, supported by scientific research.
- Reduces anxiety and promotes relaxation
One of the key benefits of L-theanine is its ability to reduce anxiety and promote relaxation. A study published in the Journal of Clinical Psychopharmacology found that L-theanine supplementation significantly reduced anxiety and increased relaxation in subjects who were undergoing a stress-inducing activity. Another study published in the Journal of Alternative and Complementary Medicine found that L-theanine supplementation reduced subjective stress and saliva cortisol levels in healthy adults.
- Improves sleep quality
L-theanine has also been shown to improve sleep quality. A study published in the Journal of Medicinal Food found that L-theanine supplementation improved sleep quality in boys with attention deficit hyperactivity disorder (ADHD). Another study published in the journal Nutrients found that L-theanine supplementation improved sleep quality and reduced sleep latency in people with anxiety disorders.
- Increases melatonin production
L-theanine has also been shown to increase melatonin production, which is a hormone that regulates the sleep-wake cycle. A study published in the Journal of Clinical Endocrinology and Metabolism found that L-theanine supplementation increased salivary melatonin levels in healthy adults.
- Enhances alpha brain waves
L-theanine has been shown to enhance alpha brain waves, which are associated with a relaxed and alert state of mind. A study published in the journal Nutritional Neuroscience found that L-theanine supplementation increased alpha brain wave activity in healthy adults.
In conclusion, L-theanine has several benefits for sleeplessness, including reducing anxiety and promoting relaxation, improving sleep quality, increasing melatonin production, and enhancing alpha brain waves. These benefits are supported by scientific research, making L-theanine a promising natural supplement for those who struggle with sleeplessness. However, it is important to note that more research is needed to fully understand the effects of L-theanine on sleep. As always, consult with your healthcare provider before starting any new supplement regimen.
