What is l theanine

L-theanine is an amino acid that's particularly known for its benefits in promoting relaxation and enhancing sleep quality. According to Andrew Huberman, it can be taken in doses of 100 to 200 milligrams about 30 to 60 minutes before sleep. It enhances sleep by increasing levels of GABA, an inhibitory neurotransmitter, which reduces forebrain activity and helps to quiet ruminating thoughts, making it easier to fall asleep 1.

Key benefits of L-theanine include:

• Promotes Relaxation: It significantly increases relaxation, which can be beneficial for those chronically stressed or anxious.
• Reduces Anxiety: Research shows it has a minor effect on anxiety and can reduce anxiety related to task completion.
• Enhances Attention: It may exert a slight positive effect on attention.
• Lowers Blood Pressure: Some studies indicate that it can help reduce blood pressure and improve overall stress responses.
• Improves Sleep Quality: It enhances sleep depth and quality for many individuals, making it a popular supplement for those with sleep issues.

Many energy drink companies are incorporating L-theanine into their formulations for its calming effects 1.

For those feeling overwhelmed by daily stressors, taking L-theanine, especially in the late afternoon, may help mitigate some stress responses and enhance well-being.
