L-Theanine Powder 100g (500 Day Supply) 100% Pure, Non-GMO, Gluten Free, Mood and Cognitive Supplement, Stress Relief and Relaxation, Scoop Included -

Product as described, perfect delivery. Great product

This seems like a very good quality supplement. It has absolutely no smell and very little taste. You can of course taste it a little, as it is a glutamate-derived amino acid. It has a slightly umami taste like MSG, but much less strong and with more earthiness. It dissolves very quickly in water. I typically put it in green tea or dissolve it in a glass of water (in 8 oz, you can't taste it at all). I take 200-400 mg a couple times a day. I lost the scoop pretty much immediately, but I would recommend volumetric dosing anyway: just dissolve a known amount into a known about of water, and take a shot or add it to your drinks. As for whether it works: I dunno. I haven't figured out whether L-theanine is a placebo for me or not, because the effects are subtle, but it does seem to calm me down, or at least make me think I can calm myself down. It works exactly as well as suntheanine capsules have worked for me in the past. I appreciate that this company lab tests (their HPLC results looked good), everything put together it seems very pure and legit.

This stuff is awsome! It took a while to find the scoop in the bag

It’s ok but not pure!

Excellent product, has helped immensely in my quest to counteract the gluteal tendonopathy I have been fighting

It's a good bang for the buck because it's powder form. You'll save a lot by getting this rather than pills, but unlike pills, this has no artificial sweetners to make it taste like strawberry, quite the opposite actually, it tasted absolutely disgusting. In the morning I usually drink 2 cups of coffee, one with this and one without. The one with the supplement tastes terrible and I try to gulp it down as fast as I can. However that's to be expected, because this isn't sugar that you're buying. This is the only L-Theanine product I've tried so far, so I don't know how it compares to others, but it works for me. For me the supplement would eliminate the negative side effects of excessive caffeine consumption. The same 2 coffee cups without it give me a headache and high heartrate for the rest of the morning. I've been able to consume up to 3 cups of coffee, 2 cups of black tea and 2 cups of green tea in a single day without side effects when taking the supplement (I know it's a lot, but I'm a student and I'm graduating soon, so there's a lot of work to be done). Now that I ran out of the supplement, I cannot exceed 2 coffee cups without getting a horrid headache and jitterness. The downsides beside the awful taste are clumping of powder, a bad scoop and packaging that is hard to open. The upsides are the cost saving compared to pill form and the effect.
