Swanson Suntheanine L-Theanine 200mg Capsules 60 Capsules

Swanson Suntheanine L-Theanine 200 mg Capsules are a daily dietary supplement designed to support balanced mental health and emotional wellbeing. Each vegan capsule provides 200 mg of Suntheanine L-theanine, with the goal of helping you feel calm while staying mentally alert, and easing nervous tension.

Suntheanine is Swanson’s branded form of L-theanine, an amino acid found almost exclusively in tea plants, particularly green tea. The brand notes that Taiyo International developed Suntheanine via a patented process intended to amplify the calming potential of L-theanine, and that it’s associated with stimulating alpha wave activity linked to “calm alertness”.

Key ingredients include rice flour, hypromellose (vegan capsule), magnesium stearate and silica. Swanson’s directions suggest taking one capsule per day with water before meals. This product is for adults only, and Swanson advises checking with a healthcare provider if you are pregnant, nursing, on medication, or have a medical condition.
