L-Theanine Capsules

Our customized L-Theanine capsules are a pure amino acid dietary supplement derived from high-quality green tea (Camellia sinensis). L-Theanine is known for its unique ability to promote relaxation without drowsiness, helping to alleviate occasional stress, enhance focus, and improve sleep quality. Each capsule provides standardized, potent L-Theanine without caffeine. As a gentle yet effective L-theanine supplement, it helps you return to a calm and clear-thinking state after stressful periods by promoting alpha brainwave activity. You can customize the dosage per capsule (100mg, 200mg, or higher) and capsule specifications according to your personal needs for a truly personalized relaxation and cognitive support solution.

Product Advantage

1. Achieve Natural Relaxation

Our L-theanine supplement helps you reach an ideal state of "calm alertness" during times of stress or fatigue, making it suitable for those who need to work efficiently without feeling drowsy.


2. Alleviates Occasional Stress & Regulates Cortisol Levels

L-theanine supplement is a gentle solution for managing daily stress, with no risk of dependence and no next-day grogginess.


3. Improves Sleep Quality Without Forcing Sleep

Unlike traditional sleep aids, L-theanine does not directly induce sleep. Instead, it improves sleep depth by reducing pre-sleep anxiety and increasing GABA levels, helping users wake up feeling refreshed and clear-headed.


4. High-Purity Standardized Extract – Pure & Safe

Each batch of L-theanine raw material is tested to ensure it is free from caffeine, pesticide residues, and heavy metals. Our L-theanine supplement is made from high-quality ingredients that meet international standards. Encapsulated in plant-based capsules, it is suitable for vegetarians, and contains no gluten, lactose, or artificial additives – offering peace of mind for long-term use.
