Natural Vitamin E

  • Vitamin E is a powerful antioxidant that supports healthy cell membranes by reducing free radical-induced damage.
  • Vitamin E is essential for the proper function of the reproductive, muscular, nervous, circulatory, and immune systems.
  • Unlike synthetic vitamin E, natural vitamin E is preferentially absorbed and transported throughout the body.

Vitamin C

  • Vitamin C supports healthy tissues by scavenging oxygen radicals from aqueous solutions, helping to reduce free radical damage.
  • Once vitamin E inactivates free radicals, it is usually no longer useful to the body. In the presence of vitamin C, however, the antioxidant properties of vitamin E can be restored.


  • Selenium is required for the production of glutathione peroxidase, an enzyme that neutralizes peroxides so they can no longer damage muscle cell integrity by reacting with the cells’ lipid membrane.
  • Selenium works in concert with vitamin E to support a reduction in oxidative stress.


  • Magnesium is a mineral that supports proper muscle and nerve functions. During exercise, magnesium is lost in sweat.
  • Much of the body’s magnesium is stored in the skeleton. The transfer from bone to bloodstream is not efficient enough for rapid replacement of magnesium losses through heavy sweating.
  • Supplementing an equine athlete’s ration with magnesium may be necessary for optimal muscle function.
