When a nervous system specialist creates a sleep supplement, you know you're in for a treat. This unique daily supplement has been designed to promote natural sleep cycles, and in a fully natural way: it's plant-powered, and some of the highlights include California poppy, melatonin, ashwagandha, kava kava (adios to anxiety), rhodiola rosea, and more. One (refillable) bottle will provide a month's worth of blissful sleep.
