Great for Relaxation and Evening Wind-Down
I really like this L-Theanine supplement and have been very happy with it. I mainly take it in the evening, and I feel like it helps me relax and wind down before bed. It seems to take the edge off and helps me settle into a calmer, more relaxed state. The capsules are easy to swallow and haven’t caused any stomach discomfort for me. I also appreciate that it’s non-GMO and gluten free, which makes me feel more confident about the quality of the product. The price is very reasonable, especially for the strength and quantity you get. The 200mg dose works well for me and the bottle lasts a good amount of time. Overall, this has been a great addition to my routine, and I plan to keep using it.

Sweet Dreams
A doctor recommended this. I take 2 an hour before I want to fall asleep. It relaxes and lowers stress. I fall asleep easily without a prescription, and I sleep well all night. No grogginess in the morning. My doctor said it's completely safe.

Consistent Quality and Excellent Value
Solid product as always from Nutricost. The quality has been consistently good, and the 200mg dose is perfect without needing multiple capsules. Easy to take, no strange taste or side effects, and the 240-count bottle lasts a long time which makes it a great value. I’ve used several Nutricost products and they’ve always been dependable. Highly recommend if you’re looking for a quality L-Theanine supplement.

I wish I had known about L-theanine sooner! Great supplement!
I am taking this with coffee on stressful days with a lot of tasks to accomplish to help me relax while staying focused. So far, it's been very effective, with no side effects I can notice. Nutricost is now one of the favorite brands for supplements. Will update if I experience any side effects. I would recommend it to anyone with a job that is both stressful and cognitively demanding.

Entspannter Fokus und mehr Gelassenheit – top Produkt!
Ich nehme das Nutricost L-Theanine 200 mg jetzt seit einigen Wochen täglich und bin wirklich begeistert von der Wirkung. Für mich ist L-Theanine die perfekte Ergänzung, um in stressigen Situationen entspannter zu bleiben und trotzdem konzentriert zu bleiben – ob bei der Arbeit, beim Lernen oder einfach im Alltag. Die Dosierung mit 200 mg pro Kapsel ist ideal: ausreichend stark, um eine spürbare Wirkung zu erzielen, ohne müde zu machen. Ich merke, wie ich ruhiger und gelassener werde, ohne an Leistungsfähigkeit einzubüßen. Das ist gerade bei hektischen Tagen eine echte Hilfe. Das Produkt ist hochwertig verarbeitet, die Kapseln sind leicht zu schlucken und geschmacksneutral – was für mich sehr wichtig ist. Außerdem sind sie frei von unnötigen Zusatzstoffen, was mein Vertrauen in die Qualität nochmal erhöht. Preislich finde ich Nutricost sehr fair, vor allem bei der Menge, die man bekommt. Die Lieferung war schnell, und die Verpackung ist praktisch und übersichtlich. Fazit: Für alle, die auf natürliche Weise entspannter und fokussierter sein möchten, ist das Nutricost L-Theanine 200 mg eine ausgezeichnete Wahl. Ich werde es definitiv weiterhin nehmen und kann es uneingeschränkt empfehlen!
