:  The present experiments were designed to test the hypothesis that elevated dietary levels of l‐tryptophan (Trp) result in elevated plasma levels of melatonin and that this increase in plasma melatonin concentration is caused by elevated melatonin production and secretion by the gastro‐intestinal‐...
