Premier Research L-Theanine 200 mg

L-theanine is an amino acid naturally associated with tea and is widely used to support relaxation without compromising mental alertness.

Premier Research L-Theanine provides 200 mg of L-theanine in every capsule, making it a convenient option for people looking to support focus, mental clarity and a calm response to everyday demands.

L-theanine is associated with alpha brain wave activity, which is linked with a relaxed yet attentive mental state. It also interacts with neurotransmitter systems involving glutamate, GABA and serotonin, helping support the balance between relaxation and mental performance.

This makes L-theanine particularly useful when calm concentration is the goal. It may also complement caffeine by supporting focused energy without excessive stimulation.

Clean, Targeted L-Theanine Support

Premier Research focuses on purposeful formulations without unnecessary additives. Each capsule provides a targeted 200 mg serving of L-theanine in a vegan-friendly capsule.
