Swanson Suntheanine L-theanine 200 mg 60 capsules.

Swanson Suntheanine L-Theanine 200mg contains Suntheanine, a patented pure form of L-theanine produced through an enzymatic fermentation process, ensuring consistent quality and potency.

L-theanine is an amino acid found naturally in green tea that promotes alpha brain wave activity—a state associated with alert, relaxed, and focused calm. It reduces the jitters associated with caffeine while enhancing its cognitive benefits, and when taken alone may improve sleep quality.

Take 1 capsule as needed to improve focus and reduce stress, or before bed to support sleep. May be combined with caffeine (1:1 to 1:2 ratio) to enhance cognitive performance. 60 capsules per bottle.
