Amazing
Great product. Proven brand. Plenty of pills for the price. Great at reducing anxiety alongside caffeine, it helps to get rid of nervous energy.

Convinced numerous friends and family to take - all say they work
Been taking these for about 9 months and one of the few supplements are I've continually taken - used on recent biking trip to the alps and really helped with focus on long days, very effective and compared to caffeine drinks much better and no tail off

Very Helpful
I use this in addition to magnesium glycenate and it has helped me fall asleep better. I love it, it helps winds me down. The supplements + reading before bed and not being on my phone has been a game changer. I don’t stress as much at night time anymore. Would recommend!

Took a while to work
So I was already taking magnesium to help me sleep which I had some initial success but then I started waking up again. Added this to my routine about 3 months ago and it did nothing for about 6 weeks. Now I’m sleeping through the night again. No nightmares.

Okay good for anxiety
This L-Theanine works pretty well for calming me down and easing anxiety. I don’t notice a big difference beyond that, but it definitely helps me feel more relaxed. Easy to take and seems like good quality overall but EXPENSIVE.

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.

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!

Honnêtement ça a changé mon quotidien instantanément, je suis de nature tendu de base. La non seulement il y’a détente corporelle, mentale et il facilite le sommeil. Pris à la base pour atténuer les symptômes d’une pathologie chronique, je ne pense pas pouvoir m’en passer. Et surtout aucune lourdeur ou sédation, au contraire on se sent juste posé et serein. Je ne peux que recommander!
