This week, we continue where we left off last week, exploring equine eye conditions through a holistic lens.

A holistic approach focuses primarily on optimizing the diet and lifestyle of horses, providing everything they need to support their overall health and maintain healthy eyes.

Long-Term Health Issues Often Begin with Deficiencies

Chronic deficiencies, prolonged stress, and toxin exposure are often the root causes of long-term health issues in horses. Those problems develop slowly, sometimes taking years to show symptoms. Even though genetics may be an underlying factor, nutrition is crucial in determining health outcomes.

Protecting the Eyes of Prey Animals

Eyesight is critical for horses to feel safe. Vision loss increases their anxiety and vulnerability. Keeping blind or visually impaired horses calm, secure, and well-supported within a herd can help to reduce their stress and improve their quality of life.

Antioxidants Play a Crucial Role in Prevention

Antioxidants help reduce oxidative stress, support immune function and detox systems, and protect the sensitive eye tissues. Even without eye symptoms, improved nutrition supports clearer and healthier eyes. A targeted supplement plan should always match the specific needs of each horse.

Selenium: An Underrated Powerhouse

Selenium deficiency is common in horses, affecting their coat, muscles, metabolism, and more. Selenium indirectly supports the eyes by boosting antioxidant defenses, especially when paired with vitamin E. While it is not an eye-specific nutrient, selenium does contribute to overall equine resilience.

Vitamin E is Essential and Often Deficient

Vitamin E is often lacking in hay-fed horses. Vitamin E protects the tissues from oxidative damage and plays a key role in eye health and detox support. High doses may be required to correct deficiencies in horses, especially for performance or aging horses.

The Right Dosage and Timing Matter

Too many antioxidants at once can overwhelm the body. Start with one or two at low doses and monitor progress over several weeks. Horses with autoimmune issues, like uveitis, need especially careful and gradual supplementation.

Zinc: The Surprise Ally for Eye Health

Zinc supports metabolism, thyroid function, liver health, and immunity. It also helps with weepy eyes and visual clarity, likely due to its high concentration in ocular tissue and role in processing light. Zinc works well with vitamin A to support vision.

Be Cautious and Responsive with Zinc

Not all horses need zinc. Try using low doses of about 150 mg elemental zinc in an organic form and observe. If there is no visible improvement within 6–8 weeks, zinc might not be the right solution.

Beta Carotene: A Natural Source of Eye Support

Beta carotene, found in fresh forage and colorful foods like carrots, supports vision and immune health. It converts to vitamin A, which helps with light processing.

Forage-based diets naturally provide more beta carotene than hay.

Support Through Food Whenever Possible

Whole foods and high-quality forage offer the best long-term nutritional support. While supplements are valuable, a varied, nutrient-dense diet reduces dependence on pills and powders and supports holistic, sustainable health.
