L-Theanine 200 mg by Nature's Way delivers a clinically studied amino acid found naturally in green tea, formulated to promote a calm, focused mental state without causing drowsiness.*


Key Benefits of L-Theanine

  • Calm Focus: Promotes a relaxed yet alert mental state, supporting concentration and cognitive clarity during periods of everyday stress.*
  • Stress Response Support: Helps maintain a balanced stress response by supporting healthy alpha brain wave activity — the same state associated with relaxed alertness.*
  • Sleep Quality Support: Promotes restful sleep by supporting the body's natural ability to wind down without sedative effects.*
  • Mood Balance: Supports a positive mood and emotional equilibrium as part of a healthy lifestyle.*
  • Antioxidant Properties: L-Theanine contributes antioxidant activity that supports overall cellular wellness.*

Why This Formula Matters

Nature's Way L-Theanine delivers 200 mg of pure L-Theanine per serving — the same dose used in clinical research evaluating its effects on relaxation and cognitive performance. L-Theanine works by supporting the production of GABA, dopamine, and serotonin — neurotransmitters involved in mood regulation, focus, and sleep quality — without the sedating effects associated with many calming supplements.* For those who consume caffeine regularly, L-Theanine is particularly well-regarded for its ability to promote smooth, focused energy by complementing caffeine's stimulating properties with a grounding, calming effect.*
