[[Serotonin]] taken orally does not pass into the serotonergic pathways of the [[central nervous system]] because it does not cross the [[blood-brain barrier]]. However, the [[amino acid]] [[tryptophan]] and its metabolite '''[[5-hydroxytryptophan]]''' ('''[[5-HTP]]'''), from which serotonin is synthesized, can and do cross the blood-brain barrier. These agents are available as [[dietary supplement]]s and may be effective serotonergic agents.
