On Your Mark Nutrition

On Your Mark Nutrition, LLC (OYMN) is an Applied Nutrition Science Concierge practice that combines physiology and nutrition for health, fitness and performance. OYMN’s main office is in Miami Beach with locations in Los Angeles, New York City and Dallas. OYMN is the only traveling concierge nutrition practice that works “in the trenches” by providing a door-to-door (or door-to-field) service that brings all testing and nutritional services to the client.

OYMN offers testing services to enhance an individual’s nutritional programming using both research-grade lab equipment and methods to accurately assess health and performance. The testing is used to develop personalized: nutrition, lifestyle and training programs.

For professional and Olympic athletes, OYMN’s services begin when the athlete meets their team’s limitations in the provision of nutritional care. OYMN transcends the ‘shotgun’ sports nutrition dogma of a ‘one-size-fits-all’ model. OYMN is the solution to ensure athletes are fit and healthy by bridging the gap between traditional and generic sports nutrition practices by focusing on nutrition programming that is based on individual physiology. The physiological and metabolic testing helps identify efficiencies and inefficiencies in the athlete that results in a stronger profiling of the athlete.

Individualized nutrition plays a bigger role the more competitive the athlete. It’s about attention to details and marginal gains. But all athletes can experience a benefit - from an Olympic athlete to the Weekend Warrior - as well as anyone who aspires to be fit and values health.

Personalized nutrition for your goals and values is a lifestyle - not a diet. Nutrition builds age-defying athletes to push their career - and success - in their sport, health and longevity.

Investigative nutrition


I hired On Your Mark Nutrition to handle the heavy lifting regarding nutrition of two major sports performance projects and was more than pleased. After those two projects I made it a priority to work with Katie Mark on anything that requires applied and cutting edge nutrition science to find a winning edge. Work with her, as the results speak for themselves.

Testing

'Test. Don't Guess.' Testing allows for individual-specific (or athlete-specific) advice rather than general advice. Interaction with actionable data is key to a personalized nutritional plan. Running diagnostics using OYMN’s technology can tell you more about what's happening inside the body in response to your nutrition and exercise compared to only body weight, body composition or performance success. This helps equip individuals with a better nutrition profile to track and manage real changes with the ultimate goal of translating to better health, lower injury/illness rates and enhanced performance.
