The precursor of serotonin is 5-Hydroxytryptophan, an amino acid. For this molecule, which is relatively less abundant in the body compared to other amino acids, (perhaps this is the reason for the unhappiness of the majority of humanity :)) ) it is difficult under normal conditions to cross the blood-brain barrier for competitive reasons. When the body becomes active, because the distribution of other amino acids changes, it becomes easier for 5-Hydroxytryptophan to cross the blood-brain barrier. As a result, increased serotonin makes us happier.
