Copper Supplementation for Horses: Strengthening Cardiovascular Health and EIPH Prevention

When it comes to the well-being of our equine companions, ensuring optimal cardiovascular health is paramount, especially for horses engaged in demanding activities like racing or competitive events. One often-overlooked but essential element in this equation is copper. In this blog, we'll explore why copper supplementation is gaining recognition for its potential role in preventing Exercise-Induced Pulmonary Hemorrhage (EIPH) and promoting overall vascular strength in horses.

  1. Copper's Crucial Role in Collagen Formation:

At the heart of copper's cardiovascular benefits lies its involvement in collagen formation. Collagen is a fundamental building block of blood vessel walls, providing the strength and elasticity necessary for proper vascular function. By acting as a cofactor for lysyl oxidase, an enzyme facilitating the cross-linking of collagen fibers, copper contributes to the integrity of arteries, capillaries, and veins.

  1. Copper as an Antioxidant Defender:

In the high-stakes world of equine athletics, oxidative stress can wreak havoc on a horse's vascular system. Copper comes to the rescue by being a key component of superoxide dismutase (SOD), an antioxidant enzyme. SOD helps shield cells, including those in blood vessels, from oxidative damage, preventing inflammation and promoting overall vascular well-being.

  1. Iron Metabolism and Blood Health:

Copper's impact on metabolism adds another layer to its cardiovascular support. Proper iron levels are essential for synthesizing hemoglobin, the oxygen-carrying molecule in red blood cells. By ensuring adequate copper levels, horse owners can indirectly contribute to maintaining healthy blood and preventing conditions such as anemia.


While the direct link between copper supplementation and EIPH prevention may not be conclusively established, the evidence supporting copper's role in overall cardiovascular health for horses is compelling. To ensure your horse's well-being, it's crucial to consider a comprehensive approach, incorporating proper training techniques, environmental conditions, and, importantly, nutritional support.

Always consult with your veterinarian before implementing any supplementation regimen. They can provide tailored advice based on your horse's individual needs, helping you navigate the path to optimal equine health and performance. Embrace the power of copper to fortify your horse's cardiovascular system and embark on a journey towards a healthier, happier equine companion.
