Mitch Cownie


NASM Certified Fitness Nutrition Specialist

I got started in the supplement industry while I was in the military as an ambassador for a supplement company. That’s when I really started taking an in depth look at what went into supplements and became interested in how they work in the body to improve performance. In 2017 we met Joel and fortunately he brought me on at Science Nutrition. The rest is history.
