What Science Says
Research indicates that L-Theanine promotes relaxation without sedation. Studies, including double-blind, placebo-controlled trials, show it can reduce stress without causing drowsiness. A meta-analysis of L-Theanine's effects on mood supports its role in enhancing relaxation without sedation.
