The Science: Small studies have shown that the root of the valerian plant, a key ingredient in this beverage, may aid in reducing insomnia—but the effect was found only at doses of 400 milligrams or more. At just 15 milligrams per can, Koma Unwind offers significantly less.
Real-Life Road Test: "At first, I chugged Koma only before bed—the grape taste was not for me, and it made me so sleepy that I was dead set against drinking it at the office. But during a particularly tough day that had me on edge, I downed a can at my desk. I could feel its effects within 30 minutes—I was able to tune out distractions and focus on the work in front of me. It definitely slowed me down a bit, but also kept me from losing the whole afternoon to anxiety and agitation."
