Coaches saying you’re not “explosive” enough
Most athletes are caught in a cycle of overtraining and under-fueling - a hidden condition known as Relative Energy Deficiency in Sport (REDs).
Add in stress from school, travel, and competition, and you’ve got allostatic load - the accumulated wear and tear that crushes recovery, weakens immunity, and slows performance.
The result?
- Your body breaks down instead of building up
- You lose your competitive edge
- Your risk of burnout and career-shortening injuries skyrockets
We combine functional medicine testing with personalized sports nutrition strategies to:
- Fix nutrient deficiencies and hormonal imbalances
- Eliminate gut issues and food sensitivities that block absorption
- Restore healthy recovery cycles
- Fuel your body for explosive performance and long-term success
This isn’t a generic meal plan or supplement bundle; it’s a precision strategy built for your body, your sport, and your season.
"My name is Bobby Nardella and I am a professional hockey player, currently with the Washington Capitals organization. I utilized Dr. Bletzinger and his functional nutrition program over the summer throughout off season training. I found that the program was extremely beneficial in identifying areas within my body makeup and diet that needed improvement. I implemented a lot of the information I received from Dr. Bletzinger into cleaning up my diet and eating foods that I knew would help me specifically. I also started taking customized vitamin packs he made which helped balance out levels in the areas I was lacking. Overall, I loved how the program was specifically built for me because everyone’s body is different, and it gave me access to information about my body that you can’t get anywhere else. I came into this season in great shape and my body composition is the best it has ever been. I give credit to Dr. Bletzinger and his program for helping me reach my training goals and boost my overall health and performance to a higher level."

I know you want to be a champion in your sport. To achieve this, you need a training and nutrition program that’s as unique as your own ambitions.

You know, they say it takes an athlete to truly understand an athlete. Well, that's me.
