I would buy this again and again.

I take this supplement every morning, and nightly just before I turn out the lights. A doctor gave it to me to produce more Serotonin, and help me sleep. He prescribed it to try and help relieve my fibromyalgia symptoms. I began to sleep so much better after two weeks of us.
