What is EO-3?

EO-3 is a rich source of the long-chain omega-3 fatty acids DHA and EPA in a palatable liquid form. EO-3 can be fed to all classes of horses, including foals, breeding stock, and performance horses to improve the critical ratio of omega-3 to omega-6 in the diet, provide preferential precursors for production of local hormones, and regulate gene expression to positively affect insulin sensitivity.

EO-3's minty apple is four times as palatable as the original. Along with a research-proven flavor, a more highly refined base oil eliminates compounds that can increase fish odors over time, without altering beneficial fatty acids. Read the research behind this product

Why should I use EO-3 for my horse?

  • Palatable distilled fish oil with a minty apple flavor
  • Improves glucose tolerance
  • Strengthens immune function
  • Increases red blood cell flexibility
  • Enhances bone metabolism and development
  • Benefits of DHA- and EPA-mediated inflammatory response include reduction in joint inflammation, allergic reactivity, exercise-induced bronchoconstriction, and exercise-induced pulmonary hemorrhage
  • Reproductive benefits include improved fertility, improved colostrum quality, enhanced passive transfer of antibodies to foals, and increased sperm concentration, motility, and viability
  • Marine-derived long-chain fatty acids DHA and EPA are more efficiently used as precursors of local hormones than plant-based sources of omega-3 fatty acids
