If you feel “wired but tired,” anxious, or notice chronic stress belly fat, L-theanine may help. This gentle amino acid naturally supports relaxation without making you drowsy.
🧠 What Is L-Theanine?
L-theanine is an amino acid found mostly in green tea.
It promotes calmness, lowers stress, and supports focus — all without sedation.
Many women use it to help with:
- Anxiety
- High cortisol
- Sleep issues
- Stress-related belly fat
- Coffee jitters
🔥 How L-Theanine Helps Lower Cortisol
✔ Supports Alpha Brain Waves
L-theanine increases alpha-wave activity — the “relaxed but alert” state.
✔ Reduces Stress Response
Research shows l-theanine may help reduce stress-induced cortisol spikes.
✔ Smooths Out Caffeine Jitters
When taken with coffee, it prevents anxiety and keeps focus steady.
✔ Supports Stress-Linked Belly Fat
By lowering cortisol, it may indirectly help with stubborn abdominal fat over time.
