This helps to relieve my anxiety. I usually take just one in the am, but was told I could take up to 3 a day.

Store mix up and mess of the original order
My order got so mixed up at the store not only was it the wrong milligram it was supposed to be 200 and ended up 100 and then I got 2 separate orders so I of course had to call and rearrange all of the mix up that happened in the store what a mess

Didn't notice a difference.
I deal with a lot of stress in my life but didn't notice a difference when taking this in dealing with the stress being easier. I was taking it along with Sam-E. I feel better results when taking Gin-Sang.

Excellent for anxiety!
I take this twice a day (am/pm) on an empty stomach for anxiety. I have tried many different brands and they don't compare to GNC. I notice a huge difference in the reduction of anxiety...don't settle for cheaper brands, it's not the same stuff!

It's keeps me clam working with middle school students!
This product certainly helps with keeping from losing your temper working with preteens and teens. I feel so at ease when taking my one capsule before I get to work. It will keep you very focus and calm. It also worked for my son with ADD.

Love it. I take it before working with children.
After getting my "Chocolate chip B-12 Vitamins" and my "Women's Ultra Mega Whole Body" I found this little gem "L-Theanine." I wish it would go on sale for $14.99 but it's worth the current member's price.

I work as a preschool teacher and although I have more than enough energy to keep up with the kids, sometimes the job can get stressful with demands from the children, employees, director and parents.

Taking one a day seems to help keep me centered and balanced.

I would recommend this product.

is it ok to take this with ashwagandha? Would that make sense?
brian k on Jan 4, 2019
