Nutricost L-Theanine Powder 100 Grams - Gluten Free & Non-GMO

I use this every night for sleep. It is super effective. I like the clean ingredients. I don’t experience any side effects and it is easy to swallow, with no taste.

It tastes sweet and savory almost like a matcha flavor. It works well and gives you a smooth calming effect

Added L-Theanine to my sleep stack based on articles I’ve read. They were right, it was a game changer, fall asleep easily and stay asleep. I definitely recommend

It definitely helps boosting my mood and making me calm. I would say effects last around 4-5 hours. Effects are very instant for me. I can feel it working within 1-3 minutes. It comes in a powder form and serving spoon is very tiny that measures at 200mg (with top being flat after filling) which is more than enough for me. Great value with 500 servings compared to pills. I would recommend to not take more than 2 servings, as long term research has not been done yet on this form of amino acid.

I took L-theanine to increase blood flow after drinking coffee. It worked.

Tastes terrible but does work and works better than pills for me.

I’ve been using this L-theanine powder regularly to take the edge off my daily caffeine intake, and it has made a huge difference. Rather than relying on fixed-dose capsules, I wanted complete control over my daily serving. Mixing a micro-scoop directly into my diet soda completely levels out my energy—I no longer experience that sharp afternoon caffeine crash, just a steady, calm focus throughout the day. Real-World Details & Performance Solubility & Flavor: The powder dissolves effortlessly into liquids with a light stir. It is completely unflavored with zero grit or bitter aftertaste. Custom Dosing: The included scoop allows for precise micro-level control, making it far superior to pre-packaged capsules. Transparent Packaging: The labeling is clean and straightforward with no filler ingredients or proprietary blends—just pure L-theanine. Value: A single 100g tub offers hundreds of servings, making the cost-per-use practically unbeatable. Pros & Cons Pros: Eliminates afternoon caffeine crashes and smooths out energy. Neutral flavor that mixes instantly into cold beverages. Full control over exact dosage via the micro-scoop. Pure, single-ingredient formula with clean labeling. Cons: Micro-scoops require a steady hand to measure accurately. Requires manual mixing, making it slightly less portable than capsules. Final Verdict I give this product 5 out of 5 stars. It’s an exceptional, high-value option for anyone looking to smooth out their caffeine response or support relaxed focus. If you appreciate transparent labeling and the flexibility to control your own dose, this is a winner. I will definitely be repurchasing!

This is an excellent product. I add it to my protein shake late at night, about 30 minutes before I go to bed, and it really helps me get high-quality deep sleep

朝や夜に鬱が酷いので飲んでみました。 躁鬱で気分の波が激しいので普段からそれに疲れていたのですが、飲んでしばらくしたら不安感や脳みそのもやもやとした悩みとかがサーってなくなってすごく気分がいいです！！ リピートしたい！

So far this stuff helps, I actually notice a difference when taking it. Definitely get a boost especially in my coffee with some maca. Helps with blood flow to fun areas of the body as well as for exercise.
