I’ve been trying out these L-Theanine capsules, and they’re pretty decent. Each one has 200 mg of L-Theanine, which is known for its calming effects without making you sleepy. It’s great for those days when you need to relax but still stay alert1. One of the main benefits is how it helps with anxiety and stress. It really helps take the edge off without any drowsiness2. Plus, it can improve focus and attention, especially if you pair it with a bit of caffeine2. So, it’s a nice combo for both chilling out and staying productive. Another cool thing is that it can help with sleep quality. Taking L-Theanine before bed can make it easier to fall asleep and get a more restful night3. It’s also been shown to boost the immune system.

This product is amazing! Nutricost L-Theanine works fast—I can feel the effects in about 30 minutes. It relaxes me and definitely puts me in a better mood. I’ve been really enjoying it, and it has a positive impact on my stress levels. If you’re looking for something to help you unwind, this is a great choice. personally, its better than "now supplement" even though it is cheaper. really recommend this product. great job nutricost
I noticed a big difference in my anxiety levels—I feel calmer throughout the day and mentally clearer, without feeling drowsy. It has also helped me sleep better at night when I take it in the afternoon.
I like this one. I've never used it before so I decided to give it a try and it really helps to keep the focus for a couple of hours. I can also feel the benefits in my energy levels. My training is better and in the office I feel more energy than usual. If you combine it with coffee you will enter the "limitless zone" 😀The package size is enormous so it can last for almost a year.
High-quality L-Theanine with a clean ingredient profile and balanced composition. The 200 mg dosage feels effective for calm energy and focus, perfect during training or study. Capsule size is easy to swallow, with no taste. The packaging is strong and keeps capsules fresh. Works well with protein and a balanced diet for muscle and mind support.
I'm in perimenopause and was struggling with racing thoughts. This product was recommended to me, so I thought I'd give it a try. I felt the effects almost immediately. I take one capsule in the morning and one at night with magnesium. I like that the container has a lot of pills. Great value for money!
I take 200mg before bed as part of my nightly routine (alongside magnesium glycinate), and it’s made a noticeable difference in how quickly I settle down and relax. No grogginess the next morning, no weird aftertaste, and the capsules are easy to swallow. Good value for the dosage compared to other brands I’ve looked at. Will repurchase.
I’ve been shopping on iHerb for a few months now, and every order has been smooth and reliable. Most recently, I purchased California Gold Nutrition Omega-3 and Herbal Immune Support Tea. Both products arrived in perfect condition, well-packaged, and with expiration dates that are far into the future — something I really value when buying supplements online.
Very good quality overall. The ingredient (L-theanine) works well for focus and calm without feeling sedated. The capsule size is easy to take, and it fits well into my daily diet and supplement routine. I use it around training, and it helps maintain steady energy and focus without jitters. Even though it’s not related to protein or muscle building directly, it supports performance by improving mental clarity and recovery between sessions. No noticeable taste, which is a plus. Overall, a reliable product that works consistently.
Nutricost is a good quality brand that I appreciate. I take this supplement to benefit relaxation and sleep. The capsules are a small size that is easy to swallow and there is no bad taste or smell associated with it. Great supplement to add to your regimen.
