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.

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.

Zen in a Capsule, Without the Weird Yoga Class
I grabbed Nutricost L-Theanine 200mg because I wanted to feel calm without turning into a monk or hugging a tree. Spoiler: it works. Why This Supplement Deserves a Chill Medal: Double Strength = Double Chill: One capsule and I go from “why is my email on fire” to “huh… maybe my inbox can wait” in like 30 minutes. Instant calm, no chanting required. 240 Capsules = Zen for Days: Honestly, I might outlive all my stress with this supply. I feel like I could survive a family reunion and a Black Friday sale without breaking a sweat. No Weird Side Effects: Unlike my attempts at meditation, this doesn’t involve falling asleep in awkward positions or drooling on the floor. Focus + Calm Combo: It’s like my brain turned down the panic volume but kept the productivity playlist going. Tiny Quibbles (Because Nothing’s Perfect): Hard to Share: My partner tried one and immediately asked for more. Apparently, calm is contagious… and addictive. Not Instant Enlightenment: It’s great, but it won’t make me levitate or solve existential mysteries. I’m still working on step two: the “inner peace while on Zoom calls.” Bottom Line: If you want to tame stress, stay alert, and pretend you’re a zen master without actually joining a monastery, these Nutricost L-Theanine capsules are your new BFF. Highly recommend for anyone whose “chill button” has gone missing.

Great L-theanine
A great and affordable L-theanine supplement. I take it in the evening for sleep in combination with L-tryptophan and melatonin. This combo works great for me. Nutricost is a relatively reputable brand and they do well in Consumerlab tests.

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!
