I can't say enough great things about medicinal mushrooms since I discovered them in 2017. I use them every single day at home and I won't travel without them. Most dramatically, Four Sigmatic's Reishi Elixr has improved my already-good sleep quality to a degree I didn't expect and am totally thrilled about. I also use every other Four Sigmatic blend, rotating them throughout the week in my smoothies or sometimes just as a tea. Between the stable energy and other scientifically proven health benefits, mushrooms are now a permanent part of my life.
