Nutrients (2023) · Meta analysis · n=495
In the 13 studies, 132 kinds of small molecule differential metabolites were extracted, 58 increased, 57 decreased and 17 had direction conflicts.
Based on preclinical studies showing neuroinflammation inhibition and lung injury models. Human clinical data lacking. Effects may vary significantly based on bioavailability and individual response.
Based on meta-analyses showing tryptophan's role in depression and serotonin pathways. Evidence comes from studies of tryptophan depletion and kynurenine pathway research rather than direct supplementation RCTs. Conservative effectiveness due to indirect evidence.
