NOW Supplements, L-Theanine 200 mg with Inositol, Stress Management*, 60 Veg Capsules
L-Theanine is an amino acid predominantly found in tea leaves, especially green tea. Structurally, it resembles the neurotransmitters glutamine and glutamate, which are vital for healthy brain function. L-Theanine is known for its unique ability to promote relaxation without causing drowsiness, making it a popular choice for stress relief. Studies indicate that L-Theanine can improve attention, focus, and cognitive function while reducing anxiety. Its calming effect is attributed to its ability to regulate levels of neurotransmitters like serotonin and dopamine. It's also known to improve sleep quality when taken in combination with other natural sedatives like GABA or melatonin. Generally, L-Theanine is well-tolerated and considered safe, but it's always a good practice to consult a healthcare provider before starting any new supplement, especially for those who are pregnant, nursing, or on other medications.
