Description

L-Theanine is a unique non-proteinogenic amino acid primarily found in green tea leaves, known for its ability to promote relaxation without drowsiness. This compound is highly valued for its role in modulating neurotransmitters in the brain, offering a calming effect that supports mental focus and stress management. It is a critical ingredient for manufacturers in the nutraceutical, functional food and beverage, and pharmaceutical industries seeking to develop products for cognitive health and mood support.

Application

• Dietary Supplements & Nootropics: Formulated into capsules, tablets, and powders to promote relaxation, improve focus, and support cognitive function.
• Functional Foods & Beverages: Incorporated into teas, energy drinks, snack bars, and confectionery to provide a calming, anti-stress benefit.
• Pharmaceutical Intermediates: Used in the research and development of pharmaceutical agents targeting anxiety, sleep disorders, and neurological conditions.
• Cosmetic & Personal Care: Applied in topical formulations for its purported anti-aging and skin-soothing properties.
• Animal Nutrition: Added to pet food and animal feed to help reduce anxiety and stress in companion and livestock animals.
• Clinical Research: Serves as a standard or active ingredient in studies investigating neurochemistry, stress response, and cognitive performance.
