This amino acid was first isolated from the milk protein, casein, in 1901 by Sir Frederick Hopkins. He was able to identify the fact that tryptophan wasn't able to be produced by the body, which makes it only available in supplemental form or through diet. Produced through a fermentative process wherein bacteria is grown in large containers. After an ideal growth period, the supplement is extracted from the bacteria and purified.

L-Tryptophan is produced through a fermentative process where large batches of bacteria is grown. L-Tryptophan is extracted from the bacteria and, ultimately, purified into the finished supplement. L-Tryptophan is an essential amino acid found in many plant and animal proteins. The term "essential" is used because our bodies can't synthesize this amino acid on its own, we have to get it from the food we eat or through a supplemental form. According to Wikipedia.com, "Tryptophan is also a precursor to the neurotransmitter serotonin, the hormone melatonin, and vitamin B3". This means, in order for the serotonin in our bodies to perform optimally, we need L-Tryptophan. In turn, melatonin is synthesized from serotonin.
