Tryptophan is metabolized in different ways. One pathway leads to serotonin and subsequently to melatonin and an array of melatonin-like chemicals called methoxyindoles produced in the pineal gland.

Tryptophan is metabolized via three pathways, the kynurenine and serotonin pathways in body cells, and via the indole pathway in gut bacteria. Disrupted tryptophan metabolism has been linked to ...

“We found that the microbiome worsens our metabolism by signaling to cells in the gut that produce serotonin,” says Damien Keating, from Australia’s Flinders University, and corresponding ...

In a report scheduled for publication in the June 2023 issue of the Journal of Affective Disorders, researchers explore the association between the gut microbiome and the efficacy of selective ...
