*by K***R on Reviewed in the United States on June 10, 2015*

The product seems to work very well.  I have a son who is currently taking authorized prescription medicine for Attention deficit issues.  However due to the side effects of the prescriptions we decided to try a natural alternative.  This supplement has worked just as well as the medicines so far, without the unwanted side effects.

### ⭐⭐ 







  
  
    Capsule size changed
  

*by S***H on Reviewed in the United States on May 5, 2017*

I've purchased this product before and would normally give 5 stars but this time I noticed the capsule size is smaller. I compared it to an empty capsule of my previous bottle and took a pic. The previous, larger capsules were always completely filled. I wish I had a filled capsule to compare the content amount to the new smaller capsule. So now I'm left wondering if the new capsules are 150mg of L- Theanine.

### ⭐⭐⭐⭐⭐ 







  
  
    Great Product
  

*by H***E on Reviewed in the United States on June 14, 2015*

I am finding the L-Theanine very helpful in keeping my anxiety down to a acceptable level.I am a full time stock trader and find it a bit stressful at times. I didn't want to take prescription drugsto calm my nerves. l searched "Nature's Valium". Several options came up, however, L-Theanine seemed to bethe best choice. Pure L-theanine is an amino acid vs. Kava, which can harm the liver.I find I am able to predict a stress filled day, take the supplement without worrying if it will hindermy quick thinking. I am able to maintain my focus as well as enjoy the calm feeling while trading.I've used it a few times now and love it.This supplier, Supernova Naturals, was great. Product as described, shipping received prior to expecteddate all the way to Hawai'i.
