Theanine 200

... which is a claim made by other manufacturers. It doesn't boost serotonin or dopamine, but that's actually good. I studied neurochemistry as a Harvard grad student, a subject I got into because my own brain was behaving like a wild experiment in same (due to a sleep disorder). This is as informed a review as you can read. So, stress and anxiety have two components. There's the bad feeling that you get when you think about the stressful thing, and there's the continual thinking about the thing itself. There's not much you can do about the former that's not worse than the stress itself (drink and drugs). So we want a way to get our minds off the thing that is stressing us out and/or making us anxious. The next question is, is this a legitimate stressful thing? Or are you being overly anxious about things that other people deal with better? Boosting serotonin treats the latter, by helping the feeling part of the brain accept the message from the thinking part of the brain that "nothing bad is likely to happen." That's why it's an effective treatment for general anxiety disorder, OCD, and the like. But it does jack-all to keep your mind off of an actual stressful situation. To do that, you want to reduce the level of the brain chemical that focuses your attention, that keeps your attention on whatever you're currently thinking about so that your mind doesn't wander. Ordinarily you want plenty of that chemical. As you might guess, when it's low, you get ADD symptoms, and boosting the chemical will treat the distractibility of ADHD. That chemical is norepinephrine (NE). (I actually figured all this out in 1998, several years before Eli Lilly stumbled on the role of NE in attention by developing Strattera). When we are in a stressful situation the brain boosts NE. That's a good idea if the stressful situation is fleeing from a bear, and your mind wandering off to some other topic will get you eaten. However, we did not evolve to deal with stressful situations that might go on day and night, like losing your job and not being able to pay your bills. In that situation, you want ordinary NE levels, so you can get your mind off the situation (and thereby reduce the stress), and only deal with it when *you* want to. You want to reduce your NE levels. And that's what this amino acid does. Really and truly. Now, how do I know that? Here's a short version of the story. All my life I've been able to do a certain type of genuine multi-tasking, namely, being deep in thought while executing tasks like making myself dinner (I’m always deep in thought). To do this, you have to continually switch your attention from the deep thoughts to the task at hand and then back, or else you won't remember what you've done. It's not something you do consciously--it just happens. Well, over the past months I lost this ability to a disturbing degree. Example: taking the milk out and putting it on the counter, then going back to the fridge and looking for the milk (with increasing frustration). Or deciding to wash my hands to take out my contacts, then finding myself sitting at my desk remembering that I had intended to do that, a few minutes ago, but having no memory at all of having done it or not. I could remember the train of deep thought, but did I do it all sitting here, or was half of it at the bathroom sink? No idea. It was clear to me that excessively high NE was preventing my brain from doing the quick unconscious attentional switches that would allow me to remember what I was doing while I'd been thinking. (Another indicator was my decreasing ability to handle hot salsa. I told you this was the short version!) Finally, I stopped executing habits; it was when I tried, for the first time in my life, to get out of the car without having unbuckled my seat belt that I finally decided to search for a natural OTC substance that might reduce NE. It worked overnight. Dramatically. And there was unexpected evidence beyond a 90% restoration of my ability to multi-task. I use Office a lot, where Ctrl-B and Ctrl-I do bold and italics, but I use another app where they do different, unfortunate things, and as hard as I could try I’d been unable to avoid using them, over and over again. Since Theanine I've been catching myself 9 times out of 10 -- the brain just goes there now on its own. But wait, there's even more. I've been on a beta (NE)-blocker for a benign but very uncomfortable irregular heartbeat for about five years. I've gotten the daily dose down from 75 mg to 50, but when I tried 25 I had some very mild symptoms the next day, under random circumstances, so I went back to 50. When my prescription ran out while I was on Theanine I decided not to refill it. Sure enough, in 10 days I've had very mild symptoms just twice, both times when I was most stressed out (driving and being late to my destination). It's not something I would have much noticed if it weren't for my history, so it's clear to me that the Theanine is handling that problem as well. I started out with 100 mg at day and upped it to 200 mg when my brain seemed to be adjusting to its presence a bit; that hasn't happened at the higher dose. I’ve also done 100 and then 200 at night. This hasn’t helped me sleep better that I can tell, but my breathing (as measured by my CPAP machine), which was always excessively deep, is more normal with it. I'll update this review if I get a better handle on that.

I have a wonderful story about Jarrow L Theanine, specifically 200mg, and more than one great story for how it calms a stressed person! Problems at work, divorce, death in the family? Oh yes, this is the thing! I was having problems at work to the point I couldn't sleep at night because my boss was torturing the staff at work. It was so stressful! I went to Sprouts and asked what their customers used when their lives fell apart. A lady led me to Jarrow 200 mg and said she thought most people took two if the emotions were pretty bad. So I did. And my stress dissolved in about half an hour. I felt calm, clear-headed, and could observe my emotions without having to suffer them. Then, my friends!, my friend came crying to me about a brutal divorce situation. She was out of her mind in grief. I offered her some L Theanine, just 2. The next morning, she came running over, saying it had saved her life and she needed the name so she could buy more, because she didn't want to be without it! Whenever she has a stressful event, she says she takes L Theanine. After my father died, I took L Theanine because it was super painful. And I still suffered a lot, but Jarrow's L Theanine helped me get through the following months. I always, always, always have it on hand! Is Jarrow's special? Yes!!! I have tried others that didn't help. As well, the 200 mg is just perfect. I do take two.

These Jarrow Formulas L-Theanine capsules are easy to swallow and come in a convenient once-daily serving size. The capsules are well-made and easy to incorporate into a regular supplement routine. The bottle is clearly labeled and simple to store. The veggie capsule format is a nice added feature. Overall, this is a straightforward and convenient option for anyone looking to add L-Theanine to their daily supplement lineup.

I have some minor anxiety issues from time to time - usually manifesting in uncontrolled nailbiting that can last for hours and until my nails are painful stubs. Often it's accompanied by a strong feeling of needing to "get out of here", or restlessness. After reading about L-Theanine on various websites, I decided to give it a shot. I like Jarrow's products overall, and this specific product uses a good quality version of L-Theanine. It has a very mild effect, but I do find that it helps me when I get that anxiety feeling. It usually kicks it within about half an hour after taking it. I've also tried using it along with caffeine as I've seen recommended by many people, but it never seems to give me that "calm-but-focused" effect others describe. I've been diagnosed with ADD (inattentive subtype) so it's possible that has something to do with it. I also drink coffee almost every morning, so maybe I'm just too accustomed to caffeine. Either way, I find it's worth the money for the anxiety reducing effects, even though I don't need it that often. I plan to keep it on hand for the foreseeable future.

We love Theanine when we can’t sleep. It does not make you tired, it simply quiets your mind to allow you to sleep.

This product has made a difference in my health. I was taking ginseng and was told that this would be a better fit for my needs. It is a companion to caffeine and if you drink a lot of coffee like I do you may want to try this product as it balances out the caffeine. Jarro brand is great for me because I cannot have dairy and don't use animal products. Dominique S

I tried a few brands and found this to be the best one so far! Another made me agitated the following day with broken sleep. However, with Jarrow I slept better and the next day felt calmer and in a better mood. A win-win.

Reiner Placebo, im Grunde Fitnessesotherik. Bin glücklicherweise zur Besinnung gekommen und habs zurückgesendet. Dazu auch noch unfassbar überteuert. Positiv: ich habe mein Geld direkt zurückbekommen

Kann leider keinerlei beruhigende Wirkung feststellen, unangenehme Magenkrämpfe allerdings schon. 20 Euro den Bach runter, aber ein Versuch war es Wert.

Ich habe dieses L-Theanine gekauft um es mit L-Theanine das ich von Bulkpowders.de gekauft habe zu vergleichen. Viele Leute auf Reddit und Youtube und so weiter, verbreiten das Suntheanine reiner ist und somit besser wirkt. Das war vielleicht damals der Fall als es viele nicht reine L-Theanine Supplements gab. Aber sobald man heutzutage von Firmen kauft denen man vertrauen kann. Bulkpowders, myprotein, mindnutrition, focussupplements und so weiter, ist es exact dasselbe. Dieses Suntheanine wirkt genau so wie normales. Also sparen Sie sich Ihr Geld. Hinzu kommt das diese Kapseln auch noch Füllstoffe wie Magnesium stearate und silicon dioxide beinhalten. Bei Bulkpowders bekommt man 50gramm für um die 13€, das Füllstofffrei ist und von ebenbürtiger Qualität. Und man kann es somit auch viel höher dosieren. Also 20€ für 12 gramm mit Füllstoffen oder 13€ für 50 gramm. Sie entscheiden selbst.

Theanin ist hauptsächlich dafür bekannt die Konzentrationsfähigkeit zu steigern wenn man es zusammen mit Koffein einnimmt (z.B. mit einer Tasse Kaffee) Bei mir macht sich die Wirkung dahingehend Bemerkbar, dass ich mich zum einen leichter, länger und intensiver auf eine Aufgabe konzentrieren kann. Man kommt in einen "Flow"-ähnlichen Gedankenfluss. Eine aufputschende Wirkung, in dem Sinne das man furious anfängt hochmotiviert zu arbeiten, sollte man aber nicht erwarten. Es ist nur eine Hilfestellung. Entspannende Effekte oder Angstreduktion, werden zwar Beschrieben, kann ich aber nicht bestätigen.

Tut exakt, was es soll. Man sollte hier allerdings beachten dass L-Theanin KEINE beruhigende Wirkung hat - es sorgt vielmehr für Zen-artigen Fokus, in's besondere in Kombination mit Koffein, was sehr beruhigend wirken kann - es jedoch nicht muss. Weiteres hebt es für mich Problemlos die Nebenwirkungen von Koffein auf.
