Melatonin

HISTORY: Melatonin is a natural endogenous hormone primarily produced by our body's pineal gland (also produced by several other tissues: The retina, thymus, spleen, ovaries, testicles, intestine, and bone marrow). Besides regulating our sleep cycle, there are many other proposed benefits to Melatonin; however, because the discovery of Melatonin was relatively recent (1958), there is still much to this substance that remains unexplored.
Once the benefits of melatonin were discovered, manufacturers began to produce it synthetically.
