Health Biologics

L-theanine is an amino acid commonly found in green tea that promotes relaxation, focus, and improved sleep quality without causing drowsiness. By boosting alpha brain waves and increasing neurotransmitters like GABA, serotonin, and dopamine, it reduces stress and anxiety. It also enhances cognitive performance, particularly when paired with caffeine, and may support immune function.
Key Benefits of L-Theanine:

• Reduced Stress and Anxiety: Promotes a "calm but alert" state by stimulating alpha brain waves, helping to manage stress-related anxiety.
• Improved Focus and Cognitive Function: Enhances attention, working memory, and mental clarity, especially when combined with caffeine.
• Better Sleep Quality: Helps people fall asleep faster and improves sleep quality by encouraging relaxation.
• Blood Pressure Management: May reduce blood pressure increases in high-stress situations.
• Immune System Support: Some studies suggest it can help strengthen the immune response and reduce inflammation.
• Neuroprotective Effects: Provides antioxidant and neuroprotective benefits, potentially supporting long-term brain health. National Institutes of Health (NIH) | (.gov) +7

Commonly Used Dosage:
While found in green tea (8–30 mg per cup), clinical studies often use 200 mg or more daily in supplement form. 
Potential Side Effects:
L-theanine is generally well-tolerated by adults, though potential side effects (rarely) may include headache or dizziness. It is best to consult a healthcare provider before adding any new supplement to your routine.
