Research suggests that Shoden ashwagandha, a standardized extract standardized to a high concentration of withanolide glycosides, may support sleep quality through both subjective and objective measures. A randomized, double-blind, placebo-controlled trial in healthy adults with non-restorative sleep found meaningful improvements in self-reported sleep quality, sleep efficiency, time to fall asleep, and nighttime wakefulness compared to placebo over six weeks. A mechanistic study using cell cultures, animal models, and EEG recordings further indicates the extract may influence sleep through GABA-related and histamine-modulating pathways, with animals showing reduced time to fall asleep and increased sleep duration, as well as enhanced slow-wave brain activity associated with deep, restorative sleep. The evidence base is still limited in size, consisting of one human clinical trial and one preclinical mechanistic study, so broader conclusions should be drawn cautiously until larger and more diverse trials are conducted.
