Unlocking Performance Potential: Strengthening Capillaries with Grape Seed Extract

When it comes to the performance and well-being of horses, maintaining optimal health and preventing injuries is of utmost importance. One particular challenge that can hinder a horse's athletic ability is exercise-induced pulmonary hemorrhage (EIPH), commonly known as lung bleeding. In recent years, grape seed extract has gained attention for its potential in strengthening capillaries and promoting circulatory health, making it a promising natural solution for preventing lung bleeding in performance horses. In this blog post, we will explore the benefits of grape seed extract and its role in enhancing the performance and overall well-being of these magnificent animals.

Understanding Exercise-Induced Pulmonary Hemorrhage (EIPH)

Exercise-induced pulmonary hemorrhage is a condition that affects horses during intense exercise. It is characterized by the rupture of small blood vessels in the lungs, leading to bleeding and impairing respiratory function. EIPH is a significant concern for both racing and performance horses, as it can compromise their ability to perform at their peak, reduce endurance, and even affect long-term health.

Strengthening Capillaries with Grape Seed Extract

Grape seed extract, derived from the seeds of grapes, is known for its potent antioxidant properties. It contains a high concentration of proanthocyanidins, which are powerful flavonoids that help protect the body's cells from oxidative damage caused by free radicals. Additionally, grape seed extract has been found to have a positive impact on blood vessels, including the tiny capillaries found in the lungs.

  1. Antioxidant Protection: Free radicals are unstable molecules that can cause damage to cells and tissues. Grape seed extract's rich antioxidant content helps neutralize these harmful molecules, reducing the oxidative stress on the body's blood vessels, including those in the lungs. By minimizing oxidative damage, grape seed extract supports the overall health and integrity of the capillaries, making them less prone to rupture during intense exercise.

  2. Strengthening Capillary Walls: The proanthocyanidins in grape seed extract have been shown to strengthen the walls of blood vessels, including capillaries. This strengthening effect improves their elasticity and resistance to damage, reducing the likelihood of rupture and subsequent bleeding. By enhancing the structural integrity of the capillaries, grape seed extract helps maintain optimal blood flow, oxygenation, and overall lung health in performance horses.

  3. Anti-Inflammatory Properties: Inflammation plays a significant role in the development and progression of lung bleeding in horses. Grape seed extract exhibits anti-inflammatory properties that help reduce inflammation in the lungs, further contributing to the prevention of EIPH. By calming the inflammatory response, grape seed extract supports the body's natural healing processes and aids in maintaining healthy lung tissue.

Using Grape Seed Extract for Performance Horses

When considering the use of grape seed extract for performance horses, it is essential to consult with a veterinarian experienced in equine health. They can evaluate the specific needs of your horse and provide tailored recommendations for dosage and administration. It is worth noting that grape seed extract is available in various forms, including capsules, powders, and liquid extracts. The recommended dosage will depend on factors such as the horse's size, weight, and overall health. Veterinarians may also suggest combining grape seed extract with other supplements or dietary adjustments to create a comprehensive approach to lung health and performance enhancement.


Grape seed extract shows promising potential as a natural solution for preventing lung bleeding in performance horses. Its ability to strengthen capillaries, provide antioxidant protection, and reduce inflammation makes it a valuable addition to an equine health regimen. By incorporating grape seed extract into a horse's routine, owners and trainers can help promote optimal lung health, enhance performance, and support the overall well-being.
