Good product
Have been taking L Theanine, specifically this brand, for years. It works well and even my teens have started taking it as needed. They say it helps them focus on school and improves mood.

Best L-Theanine for Relaxation
This is the best L-Theanine I’ve tried. It really helps relax me, especially at night. I take it with magnesium before bed and it makes me feel calm, sleepy, and ready to unwind. I’ve tried other brands, but this one works the best and feels the most consistent. It’s gentle on my stomach and helps me settle down after long, stressful days. Definitely my favorite.

Calm Focus Without Drowsiness
I’ve been using this L-theanine for months and find it very helpful for managing daily stress while staying focused. It promotes a calm, centered feeling without causing drowsiness. I notice the benefits most during the day, especially during busy or demanding moments. The formula is clean and effective. Integrative Therapeutics continues to be a brand I trust.

Focus and calm
I got this one because my doctor recommended this brand to me. It helps me stay focused and calm. Would recommend to others that need help with focusing and staying asleep through the night.

100% Recommend
Obsessed with this. If I eat late at night I have the craziest dreams or if I’m anxious I’ll be up all night with crazy dreams constantly waking up. Take these before bed and I have the best sleep I’ve ever had. Calms the mind, don’t feel drowsy after. Definitely recommend for any sleeping troubles. Helps you fall asleep and stay asleep.
