Carlyle L-Theanine 200mg Supplement | 120 Capsules | Non-GMO, Gluten Free

This works great for sleep and doesn't leave me feeling groggy the next morning

Carlyle is another brand that I trust. L theanine helps with my focus and anxiety. I take daily.

I like that this supplement is in a "serving size" I needed. It doesn't taste bad.It's easy to use and easy to swallow.It's part of a set of supplements I hope will improve, among other things, my sleep quality.Nothing I'm taking has decreased pain, but perhaps over time...It's a good value.

A high quality l theanine at a fair price. Can't go wrong.

It's good

Bought this for help with sleep. After 3 weeks of regular use before bed I can see no difference. More vitamin hype with no real proof of effectiveness.

My memory function is above average. I found that taking these (as recommended) on a empty stomach with coffee in the morning turns my brain into a computer! I can recall things that I normally cannot like the names of actors in movies, song names, my dreams from the previous night, general vocabulary enhancement, and the list goes on! It's very effective for me. I feel like my brain is 25 years old again. Zero side effects and just freakishly cool. The level of acuity lasts all morning and into the day. Sometimes I take it twice a day if I have an afternoon or evening engagement where I want to be sharp and quick witted. This is an amazing supplement (at least for my brain chemistry). It truly enhances and accentuates my intellect. Like I said, I'm already sharp in the memory "department" but these are truly brilliance in a bottle. They are a natural derivitive from tea (which I don't drink very often). I like coffee best. Try these just for the gratification of knowing how well your brain can function. Not overly stimulating and absolutely no jitters. A true gem of a supplement. This brand is the best that I have taken. I highly recommend trying it (even if don't think you need it--take it and think again)!

I have several sleep issues. I don’t really know if this works or not. It doesn’t cause any adverse effects. I can’t say I sleep better because of it - but I am giving it the benefit of doubt. I don’t know if I will get it again, but I have been using it for approximately 4 months and maybe it helps me fall asleep faster. If you don’t have numerous sleep issues maybe you will be able to experiment its effects. L-Theanine was recommended by my doctor.
