Get your beauty sleep with the help of Lion's Mane PM! Optitune™ Lions Mane Sleep™. A dietary supplement before bed may support our adrenal function; our body’s effort to regulate our neuroendocrine systems; as well as offer nourishment to our neurons. This enables a smoother transition from wake to REM, and then deep sleep by helping us wind down, reducing stress and therefore getting a better night's sleep. Lions Mane PM also supports the regenerative functions our brains perform each night for a deep, rejuvenating slumber and a healthier brain.
