Pumpkin Seeds for Sleep Quality

Research suggests that pumpkin seeds and related gourd-derived compounds may support sleep quality through several plausible mechanisms, including tryptophan content and possible interactions with GABA and opioid receptor systems. The available evidence includes one randomized controlled trial finding that tryptophan from deoiled gourd seed protein performed comparably to pharmaceutical-grade tryptophan for insomnia when paired with carbohydrates, an animal study showing that pumpkin and bottle gourd extracts prolonged sedative-induced sleep in mice, and a small pilot study in Alzheimer's patients where pumpkin seed supplementation was part of a multicomponent nursing intervention associated with improved sleep scores. All three studies point in a supportive direction, but the evidence base carries meaningful limitations: the animal study cannot be directly extrapolated to humans, the Alzheimer's pilot study bundled pumpkin seed supplementation with several other interventions making it impossible to isolate its specific contribution, and the overall number of human trials remains small. Studies indicate this is a promising but early-stage area of research, and stronger conclusions will require larger, well-controlled human trials examining pumpkin seeds as a standalone intervention.
