BulkSupplements.com L-Theanine Powder - L-Theanine Supplement, L-Theanine 200mg - Amino Amino Supplement, Pure & Gluten Free, 200mg per Serving, 100g (3.5 oz) (Pack of 1)

I just got my first order of Theanine from this specific seller (BulkSupplements) and am very happy with what I got.I use L-Theanine for mental function and I combine it with caffeine. I find it is useful in helping me focus and that with a larger dosage of caffeine (especially caffeine from guarana extract) that the effects are very pronounced. I can stay on track of tasks, sharply focus, and especially feel I work better with numbers. As all of our bodies are different and the same medication has different outcomes with different people, I cannot say if Theanine will be effective for you or not when used for this purpose. With that said, the User reviews here (and elsewhere) show that there is a pretty sizable chunk of people who have had luck using Theanine (combined with caffeine) for improved mental function.In terms of the science behind L-Theanine, the research is varied and not nearly as vast as many other supplements used for improved mental functioning. Some research has suggested Theanine has some degree of usefulness for anxiety, hyperactivity, sleep, the immune system, and mental performance. I use the word "some" because the results of clinical research has varied. Given how the same drug will affect different people in a different manner, this isn't all that surprising to see a limited number of controlled trials yield variable findings. With that said, User reviews show that Theanine has been extremely successful for some people (myself included) and so I think this is a supplement that holds potential value. Note that most of the studies which have found beneficial effects for reaction time and memory have also utilized caffeine alongside Theanine, as these two drugs seem to have synergistic effects in potentiating each other. I do not personally get any notable benefit from Theanine without simultaneous usage of caffeine.In terms of safety, I think it is always important to be aware of what goes in the body, and to be sure that what goes in our bodies come from trustable and respectable suppliers. Another Reviewer asked the question of 'how can one know they are getting real Theanine?' It's a fair question, and this is how I went about answering that question...In terms of 'knowing' if it is Theanine, I know because the difference for me is tremendous and very pronounced: for me, it takes the stimulant side of caffeine and somehow funnels it into mental sharpness. Caffeine alone does not do this, nor has any other supplement I have used for improved mental function. In terms of knowing if the product is safe and pure, I spent some time looking at different suppliers and reviews for their company and for the products they sell. I feel that this company, Bulk Supplements, has one of the best reputations on all of Amazon. Their general transaction feedback is excellent (like 99% positive), and virtually every product they sell has outstanding reviews. These thousands of stellar reviews made me feel that Bulk Supplements was a great choice to go with, and now having the product I can say I am very happy with what they sent me. So I am not sure if that is beneficial for you, but for me it was the deciding factor in buying Theanine from Bulk Supplements over other companies. I will certainly be purchasing from them in the future and I highly recommend them as a company to buy from.This Theanine (and other supplements in bulk) go along really well with a scale and a machine for making pills. As this comes in bulk powder, dosing quantity using a scoop is not the most reliable means and being able to weigh the dose is a much more consistent route. I purchased an AMW scale a few years ago for under ten bucks, so a decent-quality scale can be had for a very low price. I also own the Capsule Machine which I use to make capsules from bulk powder supplements. While there are tons of different makers producing those kinds of products, I figured I would mention those two as I purchased both on Amazon and can say first-hand that I am very happy with each. Having this scale and capsule machine makes using supplements much easier for me.So overall, I have had really good results with Theanine, and I am very happy with the Theanine that Bulk Supplements delivered on. While I cannot say if Theanine will be helpful for you or not, I can say that this is a Seller with good-quality Theanine in a pure form, and for a very reasonable price.

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.
