    L-Theanine
    So far this seems to be a good supplement. It helps take the edge off in stressful circumstances. Sleep has had a slight improvement. It has a diuretic effect though so prepare to make many trips to the bathroom.

    Great for my sleep
    Great addition to my daily supplements. I take 1 every night before bed and I really feel like it is helping the quality of my sleep. At one point I did increase to 2 caps before bed and it felt like my sleep quality declined so I dropped back down to 1 cap.

    Product great how it arrive is a different story
    The product is great. It really helps. But the box was smashed, had been opened and barely taped back together.A lot of my deliveries lately have been delayed, lost, destroyed, or show up like they rolled out of the UPS truck, ran over and picked back up before making it to my porch.
