"I bought this product because it is listed as being 400mg strong and I thought I could cut down on the number of pills I take, BUT- it is 200mg per pill which is the same as other brands here that are listed accurately as 200mg pills. Otherwise, product itself was potent."
"L-Theanine is very helpful in reducing the feelings of stress. There are no adverse side effects and no rebound fatigue. It is also helpful in reducing the effects of PMS. I had been using a different manufacturer and was reluctant to try another, but I have been very pleased with Olympian Labs. I will continue to purchase Olympian Labs. Do your research, check with your doctor, then make your purchase. You'll be very happy you did."
