New: L-Theanine - Natural Green Tea Extract (Decaf) - 120 Capsules - 300mg L-Theanine per Serving - Sleep & Relaxation Support - Mental Clarity - Non-Synthetic Theanine - UK Made - Zero Additives

Helped in the day, but not for sleep sadly.

This definitely works for me, feel a lot calmer. This is reflected by the stress level tracker on my watch, I've never seen the results as 100% relaxed. I'm normally in the normal and occasionally have medium stress levels. Have only been taking one a night, I definitely don't need two a day. Great product

I recommend L-Theanine to everyone, it really is the most underrated supplement IMO for anyone, any age. Just buy it! Been buying this brand for years.

Calming effect within 30 minutes of taking it, but after 1-2 hours gave me a terrible headache that lasted 24 hours. I took one capsule and only tried twice. Probably not the fault of the product, but I guess not all supplements are for everyone!

This l-theanine is great. Well, it is usually great! My 13 year old autistic daughter uses it for her anxiety. She can't swallow capsules so we chose this one as it has no fillers so can be dissolved in a bit of juice for her to take it. But this most recent batch the texture has changed and the powder is not dissolving completely in liquid, leaving a slightly gritty texture which my daughter is struggling with.The product itself is really good, especially if you swallow the capsules. I take it mainly for sleep but also sometimes if I'm feeling anxious or stressed during the day. It just helps quiet your brain a bit enough to chill out and settle down. It is expensive but worth it for a good quality, natural product with no fillers.

Great product, a bit expensive but doesnt have any bad things in it though. I started to sleep better %100. Take 2 calsules 30mins before going to bed.

Excellent for sleep

my concentration has massively improved with these. brilliant.
