L-Theanin

L-Theanine is an amino acid found naturally in green tea. It promotes alpha brain waves — the same state you reach during meditation — without drowsiness.

Why I Recommend It

This is the second pillar of my sleep stack. What makes L-Theanine special is its versatility: at night, it quiets mental chatter so you fall asleep faster. During the day, paired with coffee, it takes the edge off caffeine and gives you smooth, focused energy.

The key insight: L-Theanine doesn't knock you out — it reduces the mental noise that keeps you awake. That's a crucial difference.

Dual Use: Sleep & Focus

  • Evening: 200mg with Magnesium and Glycine → calm, deep sleep
  • Morning: 100mg with coffee → focused energy without jitters

Key Takeaways

  1. Promotes alpha brain waves — measurable relaxation without sedation
  2. Sunday Natural uses pure green tea extract, not synthetic
  3. Doubles as a focus enhancer when paired with caffeine
  4. Part of the sleep trio: Magnesium + L-Theanin + Glycin
  5. 100mg capsules allow flexible dosing

Who It's For

Overthinkers who can't switch off at night, anyone who wants smoother caffeine energy during the day, or biohackers building an evidence-based supplement stack.
