Great quality
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.

L theanine is great.
Theanine helps me considerably with anxiety control helps me sleep better etc. my only grieves is the scoop in this I assumed it was 200mg but my scale says 500mg 😬 above 600 is emotionally numbing. But with the proper dose this is quite effective and mixes well with anything it’s placed in to. Cost effective and hits.

Amazing price, definitely L-theanine, but 100% has a fishy smell
It's definitely l-theanine, The price is absolutely amazing can't beat it, but as others have said it definitely has a fishy smell. I like to believe it's due to this processing or the lab it was made in or something but man it is hard to imagine anything other than an external source (outside of l-theanine production) to give it that kind of a smell.

Edit: only a month later (29 Aug) price has again hiked, now to nearly £46. Abysmal. Was great, I bought this product regularly, until they upped the price from £30 to £42 in a matter of months. There’s no justification for this IMO. Since have bought elsewhere for a better price and am happy. The only upside of this product is that the bag it comes in is absolutely fantastic, long lasting.. reseals months later like new. But £12 for a better bag just isn’t worth it.

I have always bought 'Supplemented' Theanine and it helped be through a very rough few years in my life. Not finding 'Supplemented' trading on Amazon anymore, I bought these and they tasted like rice flour and when I wake at night and can't get back to sleep, 'Supplemented' Theanine always got me asleep about 20 minutes later - NOT THESE. Three times this has happened lately and I have not found that sleep after taking these. I found 'Supplemented' trading on their own online so bought some from them and now I get to sleep 20 minutes after I take them.
