Good product. I am taking it before bed in order to sleep well and to be in a positive mood during autumn, winter time when it is lack of the sun.

Great product

Posted by naturalmenopause on May 15, 2012

L-theanine is one of my favourite supplements and I use it when I want to focus, to relax or even have a good night's sleep. Doctor's Best 150mg is one that I like and agrees with me, although I take half a capsule if I don't want to be too relaxed (doesn't taste bad).

Supposed to be effective!

Posted by sweetheart on Jul 06, 2012

I have used this for a couple of days only so I can't really tell yet if it's effective or not (that's why I'm giving it only 4 stars for now). However, L-theanine is supposed to be very effective since it's one of the few natural calming "medicines" that actually has been proven to be effective in various clinical studies. If you drink coffee, you should use this too to keep your cortisol (=stress hormone) levels down, especially if you tend to gain weight on your belly which can be a symptom of elevated cortisol. (Caffeine raises cortisol levels, L-Theanine is a natural antagonist to caffeine.)

Seemed to improve mood, but can't tell if it's placebo effect...

Posted by Reviewer3065769 on Jun 19, 2012

My husband and I both tried this. It seemed to make our mood a bit smoother. Maybe helped correct some wrong thinking. The effect wasn't very strong but might be worth taking along with other relaxing supplements like lithium orotate, magnesium, tryptophan.
