Key Benefits (Why L-Theanine Is a “Calm Focus” Star!)

  • Calm Without Sleepiness: The biggest win—boosts alpha brain waves (the “chill but alert” state) without making you drowsy (unlike melatonin or valerian root)
  • Cuts Caffeine Jitters: Neutralizes coffee/energy drink jitters while keeping the alertness—so you get the focus without the shakiness
  • Reduces Stress & Anxiety: Lowers cortisol (the stress hormone) and eases racing thoughts—great for high-pressure moments (meetings, exams)
  • Improves Sleep Quality: Helps you fall asleep faster and stay in deep sleep—no “hangover” the next morning (perfect for occasional insomnia)
  • Boosts Focus & Memory: Works with caffeine to enhance attention span and memory—ideal for studying, working, or creative tasks

Quick Tip

For best results: Pair 200mg L-Theanine with 100–150mg caffeine (about a cup of coffee)—this combo is called the “golden ratio” for calm focus. If you’re sensitive to caffeine, take it alone 30 minutes before bed to wind down. And since it’s tasteless, feel free to mix it into any drink—no one will know it’s there!
