Worth it
Definitely love this product from them especially when I take it with coffee. Helps me focus and stay relaxed and I even use it at night to sleep better and it works.

Life-Changing for Anxiety & Focus
Aquí tienes una versión más concisa, muy por debajo del límite de 400 palabras: I rarely write reviews, but this product has been life-changing for me. I take one capsule about 10 minutes before my morning coffee, and I still get the energy and focus from the caffeine without the jitters, anxiety, or racing thoughts. The biggest benefit isn’t just feeling calmer. When my mind is calm, my focus and concentration improve dramatically. I can think more clearly, stay on task, and be far more productive instead of feeling overwhelmed. On especially busy or stressful workdays, I’ll take a second capsule around midday. It helps me stay calm, focused, and productive without making me feel sleepy. At night, I take one with magnesium, and it helps me relax and sleep better. If you’re sensitive to caffeine or struggle with stress or anxiety, I highly recommend giving this a try. It’s become an essential part of my daily routine.

Great for Stress Relief and Relaxing Before Bed
I’ve been taking this L-theanine supplement for a few weeks now, and it’s become a staple in my daily routine. From the moment I started, I noticed a subtle but meaningful difference in how I feel during busy or stressful parts of the day. It’s not a dramatic “knock-you-out” effect—rather, it helps promote a calm, centered feeling without any drowsiness or fogginess. The capsules are easy to take and digest well with no upset stomach, which I appreciate. I usually take mine in the afternoon when work ramps up or in the evening when I want to unwind without feeling overly tired. It pairs nicely with my lifestyle—supporting relaxation and focus without interfering with daily activities or sleep patterns. Quality seems solid. The ingredients are clean and straightforward, and there are no weird fillers or unnecessary additives. After consistent use, I’ve found myself feeling more balanced on hectic days and more able to transition out of “work mode” when the day ends. If you’re looking for a simple, effective supplement to help support calm focus and stress management without sedation, this L-theanine product is worth considering. It’s gentle, reliable, and has genuinely made a positive difference in my day-to-day wellness.

Works!
My naturopath told me about this. I am 120 pounds and he said to take 1/4 to 1/2 the capsule in herb tea before bed to unwind and feel zen. For my husband who is 250 pounds he said to take 1/2 a capsule to 1 full capsule mixed in herbal tea 40 minutes before you want to go to sleep. It works wonders for both of us. I am thankful my natropath told us about L-Theanine. I wake up feeling great.

L Theanine is my Favorite Supplement
This is easily one of my favorite supplements by far. Works extremely well for anxiety, social anxiety, mental clarity, and easing ADHD symptoms. I can’t recommend L Theanine enough. Paired with L Tyrosine has become apart of my morning stack. Reduces anxiety, stress, without drowsiness. Increases mental clarity and focus. I love the feeling L Theanine provides.

Excelente!
Muito boa para concentração e foco, vale a pena. Além de dar uma acalmada na mente e ansiedade. Se é a primeira vez tomando, recomendo começar pela de 100mg, a theanina absorve mais se for tomada 100mg de manhã e 100mg a noite. Obs; ela não tira sono, ela contribui para um sono melhor

Good value
I haven't decided yet. I think it works, but not quite sure. As far as L-Theanine goes, it is a decent price. Other formulations and companies charge more. This is the one to buy if you want to try it out.
