More about L-Tryptophan capsules 500mg

L-Tryptophan, or Tryptophan, is one of the essential amino acids that is used for the biosynthesis of proteins. In other words, most humans and animals are not able to synthesize tryptophan themselves so it must be obtained via food to ensure a healthy functioning of the body and, ultimately, to sustain life.

Tryptophan is a precursor for many compounds, such as the neurotransmitter serotonin, the hormone melatonin, and vitamin B3 (niacin). Serotonin is implicated in complex and multifaceted biological functions that modulates mood, cognition, and appetite, among others. So, low levels of serotonin could lead to both psychological and bodily implications, including  depression, lack of libido, sleeping difficulties, and gastrointestinal complaints. Melatonin not only acts as a hormone that regulates the circadian rhythms but also acts as an antioxidant and immunomodulator. Low levels could lead to sleeplessness, among others.
