L-Theanine, The Relaxation Amino Acid Book

L-Theanine Book

This L-Theanine book unlocks the gentle power of L-Theanine—an amino acid long celebrated in green tea traditions and now backed by science.

Written by Dr. Billie J. Sahley, Ph.D., C.N.C., this guide walks you through how L-Theanine supports relaxation, mental clarity, heart health, and immunity. 

LT helps without the foggy side effects or risks of habituation associated with many herbal sedatives.†

What You’ll Learn

• Alpha-Wave Brain Balance: L-Theanine enhances alpha brain waves—similar to those in deep meditation—so you feel deeply aware and relaxed, not sedated.†
• Boost Mood & Focus: Evidence shows it can reduce PMS symptoms, depressive mood, and irritability, while sharpening concentration and cognitive performance.†
• Heart & Blood Pressure: This amino acid may help lower blood pressure and protect cardiovascular health through calming, regulatory effects.†
• Immune Support with Stress Relief: By reducing stress and anxiety, L-Theanine supports immune resilience—without any adverse side effects reported.†
• Clinically Superior Calm: Sahley demonstrates how L-Theanine often outperforms common alternatives—like St. John’s Wort, kava kava, or valerian—without sedation or addiction risks.†

Why This Book Stands Out

• Scholar-Practitioner Insight: Dr. Sahley spent more than a year reviewing extensive research to craft this informative yet accessible guide.†

• Rooted in Time-Tested Tradition, Validated by Science: By blending centuries of green tea wisdom with clinical evidence, this book bridges herbal tradition with modern nutritional science.†

• Clear, Reader-Friendly Design: Unlike dense academic treatises, this guide is concise, well-organized, and designed for quick comprehension and application.

Who Will Benefit Most

• Stress-Weary Professionals: If you feel mentally taxed but don’t want heavy sedatives, L-Theanine offers calm clarity.†

• Holistic and Preventive Health Enthusiasts: Those exploring non-pharma ways to support heart health, mood, cognition, and immunity.†

• Avoiding Dependency: Unlike substances like valerian, kava, or St. John’s Wort, L-Theanine promotes relaxation without risking habit formation.†
