Tryptophan levels and metabolism are linked to migraines
the verdict
SUPPORTED
the evidence backs this
confidence 79/100
Multiple clinical and experimental studies indicate that tryptophan levels and its metabolic routes—particularly the kynurenine pathway—are significantly altered in migraine patients and play an important role in the disorder's neuroinflammatory and glutamatergic pathophysiology.
