L-Theanine Benefits and Usage
L-Theanine is beneficial for enhancing sleep quality and reducing stress. recommends taking 100 to 200 milligrams of L-Theanine about 30 to 60 minutes before sleep to help with the transition to sleep and improve its depth. This supplement increases the level of the inhibitory neurotransmitter GABA in the brain, which helps reduce activity in the forebrain and aids in falling asleep. L-Theanine is also beneficial in reducing anxiety, particularly task completion anxiety, and it can mildly improve attention and lower blood pressure 1.
Combined Effects with Caffeine
When combined with caffeine, L-Theanine can blunt some of the jitteriness and anxiety typically induced by caffeine, making it a common ingredient in energy drinks to help people consume higher amounts of caffeine without feeling overly stimulated. notes that a dosage of 200 to 400 milligrams of L-Theanine is effective for reducing caffeine jitteriness. Some people might experience enhanced effects on sleep when taking L-Theanine with caffeine, making the combination useful for controlling sleep patterns as well 2.
Other Benefits and Precautions
L-Theanine has other daytime benefits independent of caffeine, such as improving endothelial cell function and contributing to better blood flow through the vessels. However, high dosages (up to 900 milligrams per day) are generally safe but could increase sleepiness significantly, which might be undesirable during the day. It's also important to avoid this supplement if you experience night terrors or sleepwalk, as it can intensify dreams 3.
For personalized recommendations and usage, consulting a healthcare provider is advised, especially when considering higher doses or combining L-Theanine with other supplements or medications.
