A sleep trial compares ashwagandha, melatonin and their combination
Adults taking either supplement or both showed improvements in recorded sleep measures, but the abstract does not give effect sizes or clearly identify the comparisons behind its statistical tests.
Based on the published abstract. The full paper may contain additional methods, results and limitations.
The 30-second takeaway
The trial reported shorter times to fall asleep in each active treatment group, with the combination described as having the largest improvement. However, the abstract does not report how many minutes changed or clearly specify which groups were compared in the statistical tests. It therefore leaves the size of any advantage uncertain.
The abstract provides significance tests without numerical treatment effects or confidence intervals and does not clearly identify their comparators. This abstract-based account cannot establish how much sleep changed or verify an advantage of the combination over either supplement alone.
What was measured
Researchers used actigraphy to measure the main outcome: time taken to fall asleep. They also tracked total sleep time, wakefulness after falling asleep, sleep efficiency and questionnaire ratings of sleep and anxiety.
What safety reporting shows
Mild adverse events occurred in all groups, and the researchers reported no clinically significant differences between groups. That summary does not establish equivalent safety or describe longer-term outcomes beyond the trial.
