Product Description

Size: 1 Kilogram

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.

The BulkSupplements L-theanine is high quality and is comparable to any of the top capsule brands.

I don't go overboard with respect to supplementation, but I do have 6 or 7 things that I regularly take and use. I'm glad to have opted to trial L-Theanine, for it's turned out to be a pleasant discovery. I have a tendency to sometimes have racing, distracting thoughts when I try to maintain focus - this calmed me down; it relaxed me and helped sustain focus. L-theanine appears to be with me for the long haul now.

If you're interested in this effect and this product, my experience with this vendor has been a positive one.

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 made 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.

I started using Bulk Supplements L-theanine powder as an aid to enhance focus and decrease mental anxiety. Recently I have been under A LOT of stress due to outside factors and had found it difficult to focus and be motivated to do all that I need to do. I had read about using l-theanine to induce a state of calm and ordered a bag from Bulk Supplements. I only need to take the recommended dose to feel both calm and focused, much more able to perform the mental and physical tasks that I need to do without all the mental "noise".

Pro: this l-theanine supplement works, is priced well, packaged well, shipped quickly, and is sold by a trusted Amazon seller

Cons: none, except that I'd love to have a small measuring spoon included with each package.

This is a good product. I doubted that it would actually work, but the smallest dose listed on the package works well for me. I just got the supplement yesterday.

So I tried the product in the evening the first time: I had a long workout session that included functional and weight training. Then later in the evening, which was 3 hours after my workout, I took it in addition to taking 10mg of a quick dissolve melatonin tablet and I got some really good deep sleep. I slept for 6 hours and I woke up feeling refreshed compared to other days when I was only taking melatonin only or no melatonin at all.

I tried the product when I woke up: Went to class and drank coffee in addition to taking l-theanine and I was in the zone. I was so focused. But, it appears that the product beings to 'wear off' after 6 to 7 hours of ingesting it. I took my second dose, without caffeine, after coming back from a long day of class and I feel focused and very calm again. I'll take the third dose again tonight with the melatonin and I'm hoping for another good night sleep, but hopefully for 7 or 8 hours this time.

Perhaps I'll post another updated review in the coming weeks as I am also on a workout program and I suffer from restlessness at night after working out. Very nice product.

I recently received BulkSupplements Pure L-Theanine Powder and have been experimenting using it with and without caffeine (mostly BulkSupplements powdered anhydrous caffeine) of varying doses. At about a 1:2 theanine/caffeine dose, the effects are subtle, but I definitely feel less jittery and more calm in general.
I am a fairly anxious person, but as a student I can't really afford to not use caffeine right now and the synergistic effect of this product seems to be useful for my purposes.
Dosing prior to sleep seems to leave me feeling more rested than usual. If these results continue, I'll definitely consider purchasing again.
