It works! Kicks in within 30 minutes
After doing a little research on L-Theanine, I decided to try it because my husband and I are trying to conceive and I wanted a more natural way to help regulate my nervous system and manage stress. The very first night I took the 200mg dose, I noticed a difference almost immediately. My mind felt quiet for once. I felt genuinely relaxed and was able to fall asleep easily without my thoughts constantly racing. Since starting this, I honestly haven’t needed melatonin anymore. I now take it twice daily, once in the morning and once at night and it has helped me tremendously. I’ve noticed better mental clarity, less anxiety, improved productivity at work, and I don’t overanalyze or overthink everything the way I normally do. I feel calmer, more focused, and much more emotionally balanced throughout the day. For reference, I do not take any other medications for anxiety, so this was a very noticeable difference for me personally. Overall, this has become one of my favorite supplements and something I plan to continue taking consistently. For the price, it’s worth it and the capsule are very small and easy to swallow. Who would’ve thought that an amino acid could naturally make such a positive impact on your nervous system? If I could give this 10 stars, I would!! 😊

Works as well as more expensive brands at a fraction of the cost
I've been using several other more expensive brand products that contain L-theanine, which as this product is marketed, offers stress relief, better mental focus and better quality sleep. At the time that I ordered this recently, another product had gone up in price yet again and so I thought, what the heck, I'll try this less expensive brand. Having used it for several weeks, here are my thoughts. PROS: For starters, the capsules are smaller than the branded product I was using so it's easier to swallow. The quality of the L-theanine is on par with my prior product and as far as results, personally, I've found it to be equivalent to the other products out there in terms of stress reduction and improved focus. I'm thrilled that the price is a fraction of that in the other products out there. CONS: I'm slightly skeptical of this product for sleep. I know that's entirely subjective in that it didn't seem to change mine one way or the other but that's my only "negative" and really, since I'm not primarily using it for that purpose, it's not going to be something I can say much more about. OVERALL: Absolutely, unqualified YES to ordering more of this in the future. It works!

Grateful for sleep
This is a great product in the sense that it helps you get a good nights rest. The pills are small and you can’t even take them without water. I started with one and I woke myself up to three every night. You do not wake up groggy in the next day and it gives you a good night sleep.

Small easy to swallow capsules
Great for people who have a hard time swallowing large capsules. I originally bought these for a slightly smaller dosage than my 200 mg pills. Was pleasantly surprised to find that the pills are considerably smaller than the average capsules I take. I only gave four stars because I only used one day. But, so far so good, no negative side effects.

Excellent for anxiety.
I began taking these little capsules as soon as I got them, starting with one before bed. I slept great, which was a good surprise, since my cardiologist had told me to go "cold turkey" off the atenolol (25 mg. per day) which I had been taking for my blood pressure. But I found out that cutting back by even half raised my blood pressure, and pulse, plus caused anxiety to such an extreme that I was nearly shaking. Since I already knew what my doctor would say, having read reviews of people who were trying to quit atenolol (one person said that the doctor told them to not cut it back, to stay off of it, despite the withdrawal effects), I did a search for natural relief products, and found this one to be, for me, the safest bet. I'm taking one little capsule every 12 hours, and so far, I've been able to cut out 1/4 of a tablet of atenolol. I'm I'll wait a few days, then trying to cut back to 1/2 of a tablet. I'm certain that if I keep slowly cutting back, meanwhile keeping an eye on my blood pressure to be certain it isn't climbing back up to a high reading, as I learned could happen if you went off the medication quickly. (The atenolol took it down from the 150's to the teens, which caused me to become drowsy, a dangerous situation for an oldie like me.) No, I'm not someone who relies on pills to be healthy. I'm exercising, changing my diet and supplements as I've found areas for improvement, and now I'm just looking for a way to be healthy without drugs. Oh, I take homeopathic remedies for things, but the problem I had (a small stroke two and a half years ago) made it imperative for me to take medications, most of which I had to forego because they caused problems like raising my blood pressure, causing rapid pulse, even causing swelling in my neck. But ( a Eureka! moment here) I discovered that L-theanine will lower blood pressure! Therefore, I'll be taking a "medication" that's safe, effective, and will even keep my adrenaline spikes down. Which, so I hope, will keep me from having another stroke. I can't ask more than that from any source of medication.

Best product especially for anxiety
This is my favorite L-theanine product. It definitely helps with my anxiety using a smaller dose of 100 mg. I have purchased this a few times over the last year and a half, the sad thing is the prices doubled what I originally purchased it for. Seems like it goes up $4 every 6 or 8 months. You have a good product don't outsource buyers by raising the price too high.

not sure they do much
another confusing ingredient in some "nootropics". read search engine results - some say they help with energy - some say they help one sleep. i've taken them in the morning - taken them at night - saw no difference either way. however - i would go with the "help with sleep" thing - because they definitely don't help with energy. i'm old, and i've discovered the best way to boost energy in the morning is coffee, a good, reputable brand of ginkgo and a reputable multi-b. all these new "nootropics" are just yet another way for these companies to make a boatload of money. try whatever you wish - i have - i've tried SO many different "nootropics", and NOPE - they don't work. now - i can't say they don't do 'something' to one's brain - _maybe_ they do help with cognizance - maybe they could - over time - help with memory problems or other brain dysfunctions. the only way to find out is try them - which can become very costly - and end in disappointment.

Thunderstorms SUCK!
Fireworks and thunderstorms are the Devil! When I was small a tornado hit our house while we were sleeping, ever since I have been terrified of thunder and wind. So at our house both the dogs and I take these to help ease that anxiety. My husband and children call them my "calm down pills". And they do indeed help to calm us down when the thunder booms or the winds blow. The 100 mg capsule makes dosing a breeze.
