REM-3 is an innovative formula focused on stress support and sleep support all rolled into one small capsule. With Sensoril, we bring a full serving of ashwagandha to every capsule to support stress and assist in relaxation. We've also included an innovative science-backed amount of melatonin, 0.3 mg, which has shown to give the sleep benefits of melatonin without the hangout effect. If you are a fan of melatonin, you will love this formula. If you have written off melatonin in the past, we invite you to try it again, the right way.
