Tryptophan-rich foods will make you happy.

Tryptophan is an essential amino acid, meaning our bodies cannot produce it naturally, and it must be obtained through our diet. Once ingested, tryptophan serves as a precursor to serotonin, a neurotransmitter that regulates mood, sleep, appetite, and a range of emotional functions. The conversion of tryptophan into serotonin occurs in a series of intricate biochemical processes within the brain.


The significance of serotonin


Serotonin is one of four major “happy hormones”. Biochemically derived from tryptophan, serotonin is primarily found in the gastrointestinal tract (about 90% of the human body’s total serotonin is located there), blood platelets, and the central nervous system. Serotonin is a contributor to feelings of well-being and happiness. It regulates mood, appetite, and sleep. Serotonin also has some cognitive functions, including memory and learning. Modulation of serotonin at synapses is thought to be a major action of several classes of pharmacological antidepressants.

Serotonin is often referred to as the “happy hormone” due to its profound impact on mood and emotions. Adequate levels of serotonin contribute to feelings of contentment, relaxation, and a sense of well-being. Low levels of serotonin have been associated with conditions like depression, anxiety, and mood disorders.
