Works a charm
I've been using L Theanine for several years now to help with my anxiety and sleeping problems. I first found out about Theanine because Japanese green teas like Gyokuro contain *a lot* of it - so much so that you can actually taste it. I drink a lot of speciality imported green tea which has always helped me to relax, so I thought I'd venture into Theanine. The taste is amazing, very much like Gyokuro but without the caffeine. Mixability is fine, I usually have 1/4 to 1/2 a MP small scoop (a lot!) which dissolves with a few shakes, or within moments of stirring into a hot drink. As for the effectiveness; I find that the larger the dose, the quicker the effects seem to appear - usually it takes about 30-40 mins for the effects to become noticeable, but it's not as if it hits you, you just realise that you've been really calm and focused for the last 10 minutess, etc. It seems to allow me to concentrate on things better, which helps with studying. It's also great before bed as it helps me get to sleep quicker and my quality of sleep seems to also improve. I once tried a mega dose of a heaped MP small scoop, which after 30 minutes gave me the same kind of headache you get from an Acetylcholine deficiency (for the Notropic users out there who'll understand) - a kind of headache that appears at the front of your forehead, feels kind of 'cold' and lasts for an hour or so. After that, I don't think i was ever so mellow and laid back in my life before. For anyone with anxiety issues, it definitely helps me, so I'd recommend trying it. I cap it and take a cap along with a strong cup of Japanese Kabusecha before meetings with clients or my boss, and the difference to the times I forget to do that is really noticable!Goes Well With:Premium green teas. Maybe green tea extract? Any relaxing/calming supplements

Probably the most effective suppliment ive ordered from MP
I've tried all sorts of suppliments on MP, most of them are probably a con, but have found that L theanine actually makes me feel a lot more stable and less anxious. I am able to drink coffee without getting edgy, able to be in a stressful environment without feeling on edge and am able to focus a lot better on my work. I also sleep better and longer having taken 2-3 200 mg doses of it and seemingly dream more (deeper rem sleep).. Would wholly recommend this if you've got anxiety / easily stressed. Goes Well With:water.

L-theanine
I bought this to relax before bed as anxiety often keeps me from getting to sleep. I went out like a light and into a deep sleep. So it really does work. Bit disappointed as there was no measuring scoop inside the pack, and trying to read the back of the packet is impossible. I had to refer to my protein to see how much to take.

Good product
This is a great product. I mainly use it to balance the effects of caffeine but sometimes I’ll have a higher dose at night to calm me down. Makes me fall asleep easier. For the purposes it’s great and I think it’s a good value for the money. It has a slight odd taste to it so I can’t mix it with my coffee because I don’t want any other tastes to the coffee I get fresh from the roastery. The product doesn’t mix with liquids easily either. I really have to stirr to get it dissolve. Those are the minor complaints.Goes Well With:Sugar free juice.

my 2 cents about l theanine
This product makes me feel blunt when taken alone but when mixed with alcar and guarana its pure magic. It makes me happy, careless full of mental power but please do not over do it or u may have problem falling asleep. Miscibility is poor. Taste not good also but not bad either.Goes Well With:alcar, guarana

L Theanine
The taste and mixability are poor but the serving is so small it doesn't matter. Very good product, really helps me sleep at night and makes me feel so much more relaxed when i am in bed and going to sleep. I also feel fuller within my muscles, this may be due to the T-Matrix i am taking as well. But either way this is a sound product to invest it!Goes Well With:T-Matrix

Relaxing and potant!
For someone who had cut out caffine except for about 4 coffee's a week, when i do have something caffinated i am so sensitive to it and jittery etc. I bought this to help me relax and get early off to sleep if i need to get up early for gym. I can 100% say this worked for me, almost too much! I am knackered after taking it before bed and have decided only to take it the night before my rest day as I'm finding it potant stuff!Goes Well With:It's tastless and just displves in water. One bag will last you for months!!
