About Allergy Research Group - 200 mg of Zen Stress Support 120 capsules

200 mg of Zen by Allergy Research Group is a stress-support formula centered on Suntheanine®, a patented form of L-theanine derived through a fermentation process that mirrors how the compound occurs naturally in green tea. Each capsule provides 200 mg to support relaxation and help maintain a calm mental state without sedation, suited for adults managing everyday stress or seeking focused composure.

Why It's Worth Considering: Allergy Research Group uses Suntheanine®, a clinically studied, pharmaceutical-grade L-theanine with documented purity, distinguishing it from standard L-theanine extracts on the market.
