How it works

  • L-Theanine is an amino acid  found primarily in green and black tea and some mushrooms. 
  • It promotes relaxation and may ease occasional anxiety and stress while supporting memory and thinking skills (cognitive function).
  • L-Theanine may also support a good night’s sleep. 
  • Support overall health with this easy-to-take, lemon-lime flavored liquid.

Love these

I have a very hard time sleeping and these drops have worked so well!! I just take a dropper full about 30 minutes before bed and have had great sleep almost every night. The taste is also pretty good. Will keep taking these for sure!

Melissa W.
Pleasant tasting and helpful for good night’s sleep

I’ve used this nightly for over a month and I can tell a difference in how I sleep and how rested I am when I wake up. I will continue to use this as a natural way to feel relaxed and sleep easily.

Cara D.
Theanine drops

These drops are wonderful. I find they work better than other forms of theanine I have tried. They work great for calming my mind and also helping relax my mind when I sleep

Linda P.

We have not been taking it too long. Still waiting for a while longer for results.

Sleep Improvement

Taste is good. Take a couple droppers before bed! I fall asleep so amazing. I used to struggle falling asleep and don’t like melatonin. This product is my new favorite sleep aid!
