Cortisol is a hormone activated by stress. A 28-day trial found that Cortisol Manager produced a dramatic reduction in stress during the course of the study. In fact, salivary cortisol levels decreased by more than 60% after the first dose of Cortisol Manager. It increases the ability to fall asleep and stay asleep - without morning grogginess - while providing all-day stress reduction. Cortisol Manager combines proprietary stress-reducing ingredient and cortisol-lowering botanical blends to help reduce stress and relieve occasional sleeplessness.
