A placebo-controlled, randomized, double-blind clinical trial on 44 patients with a history of poor sleep was conducted at NeuroCode AG in Wetzlar, Germany. The lab specializes in brain research and is equipped with special sleep laboratories. Patients were given one daily dose of 30 drops, three times, of a valerian complex (Bioforce), or a placebo. The results showed that those who took the valerian experienced more time in deeper sleep than with placebo. The study authors concluded that one single daily dose of valerian complex leads to significantly better and deeper sleep in patients with sleeping problems.
