Proven to improve performance up to 55% and reduce post-exercise muscle stress by 36%.

Developed by leading exercise physiologists Endurox R4, with its patented* ratio of carbohydrates to protein, is proven to speed muscle recovery and reduce muscle damage following exercise.

Today, Endurox R4 is the #1 recovery drink for elite and serious atheletes in cycling, running, triathalon and swimming and is an essential part of the post-game and post-workout ritual of hockey, football, basketball, lacrosse and soccer players from high school through the professional level.

No product can help your muscles rebuild and recover faster.

Endurox® R4™ Performance/Recovery Drink!  A Breakthrough Product Based on Breakthrough Science.

Landmark research conducted over the past five years has redefined how the exercising muscle optimally performs and recovers.  This research has shown that 1) free radical build-up slows the recovery process; 2) insulin is key in restoring muscle glycogen and rebuilding protein; 3) the ratio of carbohydrate to protein called the Optimum Recovery Ratio (OR2™) is critical in optimizing glycogen restoration and 4) specific natural agents can significantly reduce exercise-induced muscle stress.

The R4 System:  for Peak Muscle Performance

  • Replenish Electrolytes and Water
  • Restore Glycogen Rapidly
  • Reduce Oxidative/Muscle Stress
  • Rebuild Protein

These important findings are the foundation of a new model for achieving peak muscle performance and recovery called the R4 system.

In 1997, leading exercise physiologists met in Colorado Springs, Colorado to formulate a new technically advanced sports drink based upon this groundbreaking model.  The result: Endurox R4 Performance/Recovery Drink.  Two recent studies (1,2) demonstrate that Endurox R4:

  • Increases endurance up to 55%*
  • Reduces free radical build-up by 69%, a cause of muscle soreness*
  • Decreases post-exercise muscle stress by 36%*
  • Increases insulin levels by 70% thereby speeding the replenishment of muscle glycogen stores and the rebuilding of protein*
  • Rehydrates as effectively as the leading sports drink*

If you are serious about working out, Endurox R4 can help enhance performance and speed muscle recovery.*
