Something's not right.
You know your horse, and when something's "off," you pick up on it in a hurry. You plan on entering an event at the end of the month and he needs to be at peak performance because the competition is going to be tough.
Oxidation of nutrients (protein, carbohydrates and fat) provides the energy needed for normal muscle function. Exercise causes a dramatic increase in this oxidation, resulting in the production of reactive oxygen species (ROS). These free radicals, or ROS, can damage DNA and contribute to degenerative changes throughout the body. Natural antioxidant defenses (endogenous antioxidants) help prevent free radical induced damage.
Most horses at one time or another are used for some type of athletic activity. This includes halter, endurance, racing and working horses. Regardless of the discipline, every horse requires energy to fuel muscle activity.
