Answers To Questions

How It Works: Your Questions Answered

Everything begins with a personal consultation. From there, you’ll choose the program tier that fits your training level—High Performer, Top Performer, or Elite Performer.

 

You’ll receive a customized lab kit to collect saliva, urine, and blood samples. These are sent to our lab to unlock the internal data that drives your program.

 

Your naturopathic doctor personally reviews your results, analyzing nutrient status, hormone balance, inflammation, recovery, gut health, and more. He builds a data-driven plan made just for you.

 

Each program includes a strategy session with your naturopathic doctor—and ongoing coaching is included in Top Performer and Elite tiers. You’ll know exactly what to eat, supplement, and adjust for maximum performance.

 

Beyond the season or the fight, you’ll build lifelong high-performance habits rooted in your own biology. This is how boxers stay healthy, focused, and dominant for years to come.

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.
