A Godsend for me
My husband and I have been taking these for a year already. I have anxiety, ptsd, cognitive decline and sleep issues. It helps. So I take one in the morning and one with magnesium before bed, and my sleeping has improved a great deal. Better than sleeping pills for me if i pair the two (i am not a doctor so ask yours. Just works for me). The energy boost is a huge help. I have to take them every day, if I miss one day eh that's OK but its good to stay consistent. No side effects which I love. Easy to take because its not too big and the capsules are easy to swallow. Having cptsd, anxiety and cognitive issues have always been an issue in my adult years especially after a head injury, but with taking these my thoughts are clearer and I show signs of being more focused. Again I recommend but please run it by your doctor first.

L- theanine 200
I’ve been using this L-Theanine supplement and I really like it. It helps me feel calmer and more relaxed without making me feel groggy during the day. I’ve also noticed that I’m able to unwind more easily at night and sleep better. The capsules are easy to take, and I’m very happy with the results so far. Definitely a great addition to my daily routine!

This actually has an effect on me
I have to admit that the majority of supplements that I've taken don't seem to do anything, at least not for me. This is one of the rare exceptions. I take this at night time most nights before going to sleep, and also sometimes if I have to play the piano in front of a group, it seems to take the edge off of the nervousness.

a Good and affordable L-Theanine supplement
I’ve been using this L-Theanine 200mg together with my coffee. It seems to help make the energetic feeling from coffee last longer while making the peak feeling less intense. For me, it also helps with focus while giving me a calmer feeling. One thing to note is that taking too much can make me feel a little drowsy or lightheaded, so I personally prefer to stay at a moderate amount 1 or 2 Capsules per day

Simple Addition to My Daily Routine
I’ve been very happy with Nutricost L-Theanine 200mg. I wanted something simple and straightforward, and the 200mg capsules make it easy to incorporate into my regular supplement routine. The biggest benefit for me is the double-strength 200mg serving, so there’s no need to take multiple lower-dose capsules. The 240-count bottle is another big plus because it lasts a long time and offers excellent value. The capsules are easy to take, the bottle is generously sized, and there’s nothing unnecessarily complicated about it. Overall, exactly what I was looking for in an L-Theanine supplement. Convenient dosage, plenty of capsules, and a good value. Five stars!

An Easy Addition to My Daily Routine
I’ve been really happy with this L-Theanine. The 200 mg capsules are easy to take, and I appreciate that one bottle has 120 servings, so it lasts a long time. I like products that are simple to work into my routine without a lot of fuss, and this checks that box. Nutricost has also been a good value compared with several other supplement brands I’ve looked at. Definitely one I would purchase again.

Mein absoluter Lebensretter für die Prüfungsphase: Der perfekte Fokus ohne "Koffein-Zittern"!
Ausgangssituation & Der richtige Kontext Gerade jetzt in der heißen Phase meiner letzten Bachelor-Prüfungen im Maschinenbau ist ein glasklarer Fokus am Schreibtisch und in der Klausur absolut essenziell. Bisher habe ich mich oft mit Kaffee oder Energydrinks über Wasser gehalten, was aber einen großen Nachteil hat: Man wird schnell fahrig, nervös und "hibbelig" – ein Zustand, den man in einer wichtigen Prüfung absolut nicht gebrauchen kann. Auf der Suche nach einer Lösung bin ich auf L-Theanin gestoßen und habe mir dieses Präparat von Nutricost bestellt. Der Praxistest: Die perfekte Kombination Isoliert eingenommen wirkt L-Theanin leicht entspannend. Seine wahre Magie entfaltet dieses Supplement für mich aber erst in Kombination mit Koffein. Ich nehme mittlerweile vor jeder Lernsession oder Prüfung genau eine Kapsel (200mg L-Theanin) zusammen mit ca. 100mg Koffein ein. Das Ergebnis ist überragend: Das L-Theanin eliminiert sämtliche negativen Nebenwirkungen des Koffeins. Keine innere Unruhe, kein Herzrasen, kein Zittern. Übrig bleibt eine unglaubliche, stundenlange Konzentration, gepaart mit einer tiefen, mentalen Entspanntheit. Ich gehe mittlerweile in absolut keine Prüfung mehr ohne diese Kombination! Die richtige Dosierung Die Dosierung von Nutricost ist mit 200mg pro Kapsel für mich der absolute "Sweet Spot". Ich habe testweise auch mal 400mg (also zwei Kapseln) probiert, was für mich persönlich aber zu viel des Guten war und mich eher zu stark entspannt hat. Die Kapseln lassen sich leicht schlucken, sind gut verträglich und der Vorrat von 120 Stück reicht ewig. Pro & Contra Pro: Eliminiert die Nervosität ("Hibbeligkeit") von Koffein komplett, schafft messerscharfen Fokus bei gleichzeitiger Entspannung, perfekte Dosierung (200mg), sehr gutes Preis-Leistungs-Verhältnis. Contra: Bisher absolut keine negativen Effekte festgestellt. Fazit Für Studenten, Büroarbeiter oder jeden, der stundenlang hochkonzentriert arbeiten muss, ist dieses L-Theanin in Kombination mit einer Tasse Kaffee oder einer Koffeintablette ein absoluter Gamechanger. Es liefert die saubere Energie, die man braucht, ohne den unerwünschten "Koffein-Crash" danach. Absolute Kaufempfehlung – mein wichtigster Begleiter in der Klausurenphase!

Early review-Works!
This is my 2nd day of use. I have used L-Theanine previously (on and off) from a different brand. This is my first experience with Nutricost. All the classic effects of L-theanine are felt within 1 hour. Beautiful, bliss, calm, empathetic, focus. Great for spending time with loved one. Great for building relations. L-theanine is a beautiful molecule. But from my previous experience, the effects stop after a few days due to tolerance buildup. Have to wait and see. I will update after some days.
