SuperSport Amino Acid Supplement

Once again, the Ph.D. Equine Nutritionists at Purina are on the cutting edge of equine nutrition research, developing a proprietary blend of amino acids, vitamins, and minerals proven to support muscle performance.

In published scientific research, feeding Purina® SuperSport™ horse supplement resulted in significant optimization of some of the key measures that are critically important to top equine athletes. In a controlled study performed in 2011, horses fed the Purina® SuperSport™ horse supplement showed statistically significant differences in muscle development, exercise recovery, and overall athletic fitness and performance when compared to horses that did not receive the supplement and were fed a similar level of protein from alfalfa pellets.

Creatine kinase, a key indicator of muscle strain or damage, returned to pre-exercise levels 24 hours after exercise in horses receiving Purina® SuperSport™ pellet. Levels remained significantly elevated in alfalfa-supplemented horses at 24 hours after exercise.

During graded exercise testing, horses supplemented with SuperSport™ pellet showed a significant difference in top speed and time to fatigue compared to alfalfa-supplemented horses. SuperSport™ pellet-supplemented horses also optimized their oxygen-utilizing capacity (VO2 max) and anaerobic threshold (VLa4) during the graded exercise test, while alfalfa-supplemented horses did not.

Horses receiving SuperSport™ supplement had greater forearm muscle circumference and less body fat than alfalfa-supplemented horses. A subjective muscle mass scoring system also showed positive differences in the overall muscling of horses fed SuperSport™ supplement.
