In a German home-based trial, 155 adults aged 18 to 65 taking 250mg nightly for four weeks saw insomnia scores fall 3.9 points versus 2.3 with placebo.
The study, led by Julius Schuster of Leibniz University Hannover, found 93% reported no adverse events, but researchers said the benefit was small and not proof of a cure.
Most participants were women and outcomes were largely questionnaire-based, with little diary data and no objective sleep tracking; researchers said longer studies are needed and persistent insomnia still warrants established treatment.

Why do we chase minor supplement fixes when proven, drug-free insomnia therapies already exist?

If self-reported sleep is unreliable, are studies without objective trackers fundamentally flawed?
