Pure Encapsulations L-Theanine is a relaxation supplement that can help soothe irritability, control stress reaction, and promote a calm and focused state of mind. But what is L-theanine and how does your body use it?

L-theanine is an amino acid that’s found in different types of teas and other foods. When ingested, this natural compound can produce a relaxing effect and allow you to cope with occasional stressors calmly.

  • Stay Relaxed: Helps achieve a relaxed state of mind
  • Improves Stress Response: Aids in controlling reactions to every day, occasional stressors
  • Mood Enhances: Soothes irritability
  • Provides Nervous Tension Support: Yes

One of the best parts about this L-theanine supplement is that it provides stress relief without producing drowsiness. This makes it an ideal solution for both professional and personal situations — everything from important meetings to family reunions. Aside from soothing irritability, L-theanine also promotes antioxidant activity and may even reduce heart rate when you’re in stressful situations.

What’s more, this L-theanine supplement can increase focus and attention, with effects similar to that of caffeine. This compound can also help boost the immune system, improve sleep quality, and promote the movement of cilia in the nose, which helps to regulate sinus function.

If you’re looking for the best L-theanine supplement available, Pure Encapsulations L-Theanine is a great choice that improves occasional stress response and soothes irritability without producing sleepiness or drowsiness.
