Solus 

Dietary Supplement. Sleep & Relaxation Aid. All natural. With 5 HTP. Nature's safe, effective sleep amino. L-Tryptophan is an essential amino acid, which means that it must be consumed from food or supplements since the body cannot make it using other amino acids. It is present in virtually all plant and animal proteins. After the body absorbs L-Tryptophan, it may ultimately be converted into neurotransmitter serotonin. It is primarily the serotonin which then does much of what L-Tryptophan is known for. For example, serotonin is the precursor to the sleep hormone, melatonin. Research has shown the L-Tryptophan is effective for inducing sleep, reducing symptoms associated with premenstrual disorder, and supporting a positive mood.
