i play college football and recovery is everything. My sports nutritionist mentioned cortisol affects sleep quality and muscle recovery. Started Mello and my sleep tracker went from 60 percent quality to 84 percent in two weeks. Numbers do not lie

I am a chronic overthinker and bedtime was the worst because I had nothing to distract me. Mello does not knock me out it just takes the edge off enough that my brain stops spiraling. I actually look forward to bedtime now which is something I have never said in my life.

I am 52 and going through perimenopause and the sleep issues were destroying me. My doctor had no real solutions. Found Mello through a Facebook group for women my age. Three weeks in and I am sleeping through the night consistently. Wish I found this sooner.
