31 Mar 2020 --- Stratum Nutrition’s NEM – short for natural eggshell membrane – has received confirmation in a new independent study that it can reduce joint pain and stiffness in patients with grade 2 and 3 osteoarthritis knee (OA). The new statistics show that the ingredient made from upcycled eggshell membranes can take effect within seven to ten days, with clinically meaningful benefits persisting for 90 days. Tapping into both the growing naturality and the nascent upcycling food trends, NEM not only supports joint flexibility quickly but also ensures positive future joint health.
