## Description

L-Theanine is an amino acid that is naturally found in green tea Green tea is widely reported as being very healthful and is found in the form of an extract in everything from power bars to ice cream these days This is because green tea is a source of polyphenols which have antioxidant properties keeping healthy cells from being damaged by harmful outside sources like free radicals Since green tea in America generally has less than 10mg theanine in it very few people actually see its effects in action This supplement is a better source

Review: BulkSupplements has done us a great favor by offering us L-Theanine in bulk form. This is usually a rather hard to find and expensive supplement. This is the cheapest I've seen it. It is pure and it is the real deal and packaged in the U.S., so you know you're not getting fake stuff from China. L-Theanine is the stuff in tea that makes you feel calm and relaxed. I was once placed temporarily on Xanax for anxiety attacks that had no explanation. Then I looked up the side-effects of Xanax and found out how addictive that stuff was and how it has brought so many onto a downward spiral of misery. I started looking for more-friendly, all-natural alternatives, and that's when a web search revealed L-Theanine as an alternative to me. I didn't stop the Xanax cold turkey, but within two weeks, I was able to titrate and wean myself off of it entirely and replace it with L-Theanine. I then slowly reduced the amount of L-Theanine I was taking down to 100 mg. I now only take it because it makes me feel better during generally stressful situations, not because I need it. This a very powerful amino acid. It can also take the edge off of caffieine if you use that as a smart drug. L-Theanine + Caffeine = a feeling of clear focus without the crash or jitteryness. No daily recommended value has been established, but I would suggest taking 200 mg once to twice daily (400 mg max) and starting out from there. I've found that if I go over 400mg, I start to feel really drowsy and sluggish. Each person is different, so you may have to vary this amount for you. Also, if you want lucid dreams or have trouble sleeping, this is an excellent addition to melatonin. L-Theanine is for the most part non-toxic. There are no documented cases of anyone overdosing on it, but to be on the safe side, handle it like care like any other supplement. The package says on it, "Do not use if you are taking blood pressure medication." This does not necessarily mean that you can't use it. I am currently taking blood pressure medication for high blood pressure and I am doing just fine on L-Theanine. I have also never heard of anyone one high blood pressure medication having problems with L-Theanine. I believe this statement is just a warning so that the company can protect itself from liability in the rare event that someone does have a reaction. If you want to be 100% safe, talk to your doctor first. But, remember, this is pretty much a refined tea leaf-type extract without the caffeine stuff. If you drink lots of green tea, then you probably are already getting lots of L-Theanine in your diet.
Review: I've been using this for about a week. I got it to help with sleeping,... it does seem to work, boosting both sleep and focus. I kind of got it on a lark, I'd never tried it before. I wasn't obvious to me that something that comes from green tea would help with sleeping. There were lots of positive reviews so I decided it was worth a try. For me it seems to work great. I'd say it definitely promotes a calm focus affect. This stuff takes a while to dissolve, the powder is fine, so I believe this is a characteristic of the Theanine itself. ....At the rate I'm using this stuff it's going to last a very long time. I've used several Bulk Supplements products and so far they all seem to be of good quality. A number of people seem to need a way to make small measurements, Bulk Supplements doesn't provide any form of measuring spoon. I bought a set of very small measuring spoons from desertcart that does the trick nicely. It works for this and any other small dose supplements. It has the odd name of Norpro Mini Stainless Steel Measuring Spoons, Set of 5 (tad, dash, pinch, smidgen and drop). It's difficult to measure how accurate you are measuring small amounts of powders and liquids, so they loose the fractions of a teaspoon and come up with frankly hilarious and imprecise names for the size of the spoons. A dose of L-Theanine using these spoons is between a 'pinch' and a 'dash'. To be more precise(the right way) you would want to use a very accurate weighing device, which uses weight which is more accurate versus volume. I guess I'm willing to be a bit flexible on the exactness and go with 'the ease of use' spoons. You want to move a knife across the top of the spoon to get some consistency with the measurements. As others have mentioned the reseal on the bags really isn't very good, consider transferring the powder to another container. ...Otherwise the bag is a nice weight foil lined bag that gets the product to you in good condition. So,.. so far I'm really happy I tried this stuff. I think you could be happy too, thinking everyone could use more focus and calm.
