Frequently Asked Questions
What is L-theanine and how does it work for sleep?
L-theanine is an amino acid found primarily in tea leaves. It promotes relaxation by increasing alpha brain waves, which are associated with a calm, focused state. It does not cause drowsiness but can improve sleep quality by reducing anxiety and stress. Many people take it before bed to wind down naturally.
Can I get enough L-theanine from drinking tea?
Yes, but the amount varies. A cup of green tea typically contains 8 to 30 mg of L-theanine. Guayusa tea from Amazonian Treasure provides a moderate amount along with caffeine and antioxidants. For a higher, more consistent dose, a supplement like Amazon Elements L-Theanine (200 mg per capsule) is more effective. Check our L-theanine for sleep comparison for more details.
Is L-theanine safe to take daily?
L-theanine is generally recognized as safe (GRAS) and has a low risk of side effects. Studies have used doses up to 400 mg daily for weeks without adverse effects. Both products reviewed are suitable for daily use. However, consult your healthcare provider before starting any new supplement, especially if you are pregnant, nursing, or taking medication.
How does Guayusa tea compare to green tea for L-theanine?
