antioxidants for horses

Oxidation is a process a horse’s body uses to transform nutrients such as carbohydrates, fats, and proteins into energy. But during this process, a few unstable oxygen molecules called free radicals develop. These molecules have an unpaired electron that makes them quick to react with other molecules, stealing electrons from their outer orbits. This damages the other molecules and can irreparably damage cell walls.

Fortunately, antioxidants can help stabilize free radicals and halt oxidative damage, making them an important part of the horse’s nutritional needs. How much do you know about antioxidants and how they impact your horse? Don’t worry. We’re here to help.
