BulkSupplements.com L-Theanine Powder - L-Theanine Supplement, L-Theanine 200mg - Amino Amino Supplement, Pure & Gluten Free, 200mg per Serving, 1kg (2.2 lbs) (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.

I love this collagen. Zero fish taste or smell, mixes easily and easy to take. I think it has way less of a "heavier" or collagen-y taste than typical types and sits better for me. The bag however, how I wish their package seal would work or work consistently. I got over that and just fold out air and clip, lol. I think a good price and does the trick for me, wouldn't hesitate purchasing again and again.

Great supplement. Can’t taste it. Mixes smooth.

Great Product

This is the second time I am buying. I use it to brush my teeth and second important is I use it in my coffee or tea with caffeine. L-theanine Is helping caffeine to increase my blood pressure. I will recommend.

Great way to mitigate caffeine jitters and enhance focus. Make sure to measure 1:2 caffeine to l-theanine and you'll be golden.

L-Theanine has helped me achieve a calm and focused state of mind. I began taking it along with l-tyrosine first thing in the morning with a glass of water. After a few days I noticed that in my early morning mental haze I gravitated toward the supplements even before I headed to the coffee pot. At the advice of my veterinarian, I began giving l-theanine to one of my dogs and my cat. The dog now responds more quickly to voice commands when we're out in the field or in the back yard. He sleeps more during the day. I gave him l-theanine, colostrum, and a soup bone filled with cheese, and he got through the latest round of neighborhood fireworks in his crate looking mildly concerned, but not alarmed, and not panicked like last year. On l-theanine, cat has gone from being completely crazy and unwilling to share the house with the dogs, to being irritable. With the addition of colostrum, he is now also often willing to be in the same room with the dogs. While I'm fine taking l-theanine capsules, my pets are not. BulkSupplements' pure l-theanine powder provides a larger dose with less volume, which has made it easy to hide the l-theanine in just a little bit of wet food - even easier.EDITED TO ADD: I just ordered more so that I will not run out of L-theanine to give to my cat. Tonight for the first time, my cat came up from the basement and sat on the livingroom couch with the dogs, and the dogs didn't chase him. Amazing results all around. This L-theanine product has been an important part of calming down my irritable (hissing, scratching, biting, running) cat and the dog with high prey drive. I went to Reactivity training for myself (and the dog), give the dog regular exercise and training, and give the cat the following: 1 teaspoon of L-theanine from BulkSupplements and 2 capsules' worth of colostrum powder mixed into one can (5.5 oz) of my cat's favorite wet cat food and 5.5 oz of water. I put all four ingredients into one of those protein shaker cups, to mix it up, and pour the very liquid mix into a bowl. My cat eats all of this in a day or two (more in winter, less in summer). I'm glad I can buy this stuff in a bag instead of having to open up little capsules first thing in the morning.I'm happy to put 1/2 or 1 teaspoon of the powder into a glass of water and drink it plain - the powder doesn't mix well, but it has only a slightly sweet taste and it floats on top of the water/ goes down fast. I wouldn't hesitate to add it to a smoothie, it's just that I want to keep my mornings simple and this stuff is well tolerated on an empty stomach.
