Leading the pack for sleep quality

This is one of many hacks I have tried to improve the quality of my sleep. I track my sleep in various ways (Fitbit, Oura, personal assessment of well being) and there has been a measurable improvement since I've been taking this. Things that didn't work so well: magnesium glycinate, ZMA, melatonin, glycine (worked for a while but then didn't). Progesterone cream has also been effective but this L-theanine has been more consistent. I have yet to do a proper assessment of GABA, magnesium threonate, & 5HTP which are all on my list of hacks to try... so those might yet unseat the current champion.

Theanine (200mg) is part of a regimen I take to get deep restful sleep, along with Ashwagandha (150mg), melatonin (10mg), HTTP (100mg), magnesium citrate (50mg), zinc(15mg), l-lysine (1,200mg) and l-arginine (1,200mg). I don't need it every night. But when I need it, I always can count on it to put me right to sleep and wake up refreshed. You can take theanine by itself, too, for stress relief, mental clarity and many other benefits.

I have been taking this to ease the intensity of my anxiety symptoms. The main benefit of this supplement for me was general relaxed feeling, while still having a lot of energy. I was taking it in the morning, 2 hours after my breakfast. I really appreciated the absense of drowsiness after it. The capsules are small in size, very easy to swallow.

I must say, Jarrow Formulas Theanine Veggie Caps really knocked my socks off! Not only did they give me a boost of mental clarity and focus, but they also helped me feel calm and collected in the face of even the most stressful situations. And let's talk about those veggie caps, shall we? Not only are they easy to swallow, but they're also made from all-natural, plant-based ingredients that will have even the most devoted carnivores feeling like they're living their best veggie life. Overall, I'd say that Jarrow Formulas Theanine Veggie Caps are a fantastic choice for anyone looking to boost their cognitive function and promote a sense of calm in their daily lives. So if you're looking for a supplement that's both effective and ethical, look no further than Jarrow Formulas!

I struggle staying asleep, often waking up around 3/4a with my mind racing (thank you, ADHD!). A year and a half ago, a friend recommended l-theanine for its relaxing properties and I’ve been taking it ever since. I still occasionally wake up, but go back to sleep faster, and most of the time don’t wake up. It’s wonderful and I highly recommend!

THIS IS THE ONLY RELAXING THING TO TAKE DURING EXAMS! anything else will cause drowsiness. Generally, I love all Jarrow Formulas products, they are always top-notch. This L-theanine is no exception. This is the proper dosage. I can recommend, generally, to take it on a need-basis and don't take it daily for years, as it'll stop working at some point as your body gets used to it. But definitely, by far, the best alternative to addictive and brain-damaging benzodiazepines. I've known and used L-theanine for over 15 years now - on and off, but a lot before and during exams at university.

This is another quality product from Jarrow formulas that has great packaging, easy to swallow pills with no taste, and are effective to give a level of relaxation. I take it with my caffeine to curb the anxiety I sometimes get with caffeine. I get my energy but also feel calm at the same time. Part of my diet.

I wasn’t so sure it was doing much, but when I suddenly went without it I found myself feeling extremely irritable. It helps with insomnia as well. It’s not a magical fix, but I don’t wake up as many times in the night and I can tell my sleep is deeper because I have more dreams. Take it twice a day for best results! In the morning & at night. Not sure how much it helps with anxiety though, which is why I bought it

Jarrow Formulas suppliements often do its work. My husband has slept better while he takes this theanine before he sleeps. He also tried one herb blends cap by another brand for better sleep and it didn't work like this one. However, he isn’t taking them anymore, he feels heartburn when he has theanine.
