Worth the price for this supplement
I noticed a difference within the first 3 days of taking this. I went from dragging and lagging behind to wide awake, alert and focused. I take 2 with a cup of coffee in the morning.

Good Results
I’ve taken L-theanine from other brands before with no effect. Many years later I was still having quality of sleep issues and mentioned it to my doctor. She said I was likely not taking the right dosage and recommended this brand but at a dosage of 3 capsules before bed (600mg). It is hard to describe its effect but my sleep monitors all show positive results and I just feel better in the morning. As always, we are all all different and your results may be vary.

Great Product for Relaxation
I have used this supplement for years for relaxation and sleep. It is a natural way to help me with sleep. Ordering from Amazon is so easy and convenient, too. L-theanine works well.
