L-Theanine is an amino acid that is found in green tea and is a natural remedy that is often used to help alleviate the physical and psychological stresses of daily life

Research suggests that L-Theanine supplements may have several potential benefits, like reducing stress and anxiety, improving cognitive function, promoting better sleep quality, and enhancing immune function. Additionally, some studies have suggested that L-Theanine may help to reduce blood pressure and improve cardiovascular health.

L-Theanine is generally considered safe when taken at recommended dosages, and negative side effects are rare. However, some people may experience mild side effects, including:

  • Headaches
  • Dizziness
  • GI upset (nausea, diarrhea)
  • Sleepiness or drowsiness

It is believed that L-Theanine can be used as an anti-anxiety medication that may help alleviate anxiety by increasing alpha waves in the brain, which promotes a state of relaxation without causing drowsiness.

Studies have found that L-Theanine may be beneficial in the treatment of generalized anxiety disorder, schizophrenia, schizoaffective disorder, and attention deficit hyperactivity disorder (ADHD) by reducing symptoms of anxiety and improving sleep and cognitive performance (1) (2).

L-Theanine is generally considered safe for most people when taken at recommended dosages, and there is no evidence to suggest that taking L-Theanine supplements every night is harmful. It is recommended to start with a low dosage and gradually increase it to the recommended dose, as this may help reduce the risk of side effects.
