L-Theanine

Sleep & Cognitive Support

Here’s how to ensure you get the most out of your L-Theanine.

Essential Info

How Much To Take

The ideal dose depends on your desired outcome:

  • For Stress & Relaxation 
  • 200mg per day can help lower cortisol levels and promote a relaxed state.
  • For Cognitive Performance 
  • 200mg, often paired with 50–100mg of caffeine, enhances focus, reaction time, and sustained attention.
  • For Sleep Support 
  • 200–400mg taken before bed can improve sleep quality by calming an overactive mind.

It's important to start with a lower dose and adjust as needed, based on your individual response. Some people may require higher amounts for sleep, while smaller doses may be sufficient for stress and focus.


When To Take

L-theanine works best when taken 30–60 minutes before the desired effect:

  • Morning or Afternoon (With Caffeine): Enhances focus and alertness without jitters.
  • Evening (Before Bed): Supports relaxation and improves sleep quality.
  • During Stressful Situations: Can be taken as needed to promote calmness.
  • Specifically, L-Theanine is not a sedative. Rather, it promotes relaxation, so feel free to take it when you’re ready to unwind or getting into bed, even if you’re still planning to read for a while.


To Ensure You Get Results

  • L-Theanine works best when taken daily – not just when you’re struggling with sleep.
  • It supports your brain’s natural ability to relax, building a foundation of calm over time.
  • Daily use helps your brain build a consistent, natural rhythm of relaxation—so you’re not just reacting to bad nights, you’re preventing them.

What Results To Expect

While some people notice immediate calming effects, consistent use for 6–8 weeks may provide the most significant benefits for sleep and stress resilience.

Importance Of Daily Use

  • 1.

    Consistency in your routine – taking L-Theanine daily! – helps speed up the benefits.

  • 2.

    Take your L-Theanine every day, not just on days you think you need help with sleep. This is because it actually works at the brain level to relax you. Don’t think of this as a sleeping pill. Instead, it’s creating a calming effect in your brain.

  • 3.

    You want to give yourself a daily infusion. Skipping days will slow your progress.

Tips to Achieve Daily Use for Max Benefits

  • 1.

    Decide what time of the night is most convenient for you to take your L-Theanine, and set a reminder on your phone.

  • 2.

    Keep your L-Theanine handy. Maybe on your nightstand, or your bathroom cabinet, anywhere you’re likely to be about 30min prior to falling asleep.

  • 3.

    Track your progress. Whether it’s keeping a daily journal or just doing quick check-ins with yourself, focusing on how far you’ve come is a great way to stay motivated and consistent.
