The Phenom team has helped me tremendously throughout my career. With the contestant testing and communication, I know my nutrition and supplements are always optimized for me to perform and recover my best. I really felt the difference when I started working with them a few years into my NHL career. My goals change in the off-season and in-season, and this program helps me achieve those.

I’ve been working with the team for over 2 years now and I’ve noticed a drastic change in multiple areas. Energy levels pre and post training have significantly improved as well as my sleep & overall recovery. They have helped me figure out food sensitivities and that’s driven me to fuelling with food that works with my body and not against it. Overall, they are the best & I can’t wait to continue working with them.
