Vitamins and Minerals

Vitamins and minerals play crucial roles in supporting the health and well-being of horses overall. Here's an overview of the direct benefits:


  1. Vitamin A:

    • Benefits: Supports healthy vision, skin, and immune function.

  2. Vitamin D:

    • Benefits: Aids in calcium absorption for strong bones and teeth.

  3. Vitamin E:

    • Benefits: Acts as an antioxidant, supporting muscle health and immune function.

  4. Vitamin K:

    • Benefits: Essential for blood clotting and bone metabolism.

  5. B Vitamins (B1, B2, B3, B6, B12):

    • Benefits: Contribute to energy metabolism, nervous system function, and overall vitality.


  1. Calcium and Phosphorus:

    • Benefits: Essential for strong bones, teeth, and overall structural support.

  2. Sodium and Chloride (Salt):

    • Benefits: Maintains hydration, supports nerve function, and aids digestion.

  3. Magnesium:

    • Benefits: Supports muscle function, nerve transmission, and energy metabolism.

  4. Potassium:

    • Benefits: Important for nerve and muscle function, acid-base balance, and hydration.

  5. Selenium:

    • Benefits: Acts as an antioxidant, supports immune function and muscle health.

Minerals play a crucial role in equine eye health, and deficiencies or imbalances can contribute to various eye issues.

Relationship between Minerals and Equine Eye Health:

  • Corneal Health: Vitamin A, zinc, and copper are particularly important for maintaining the health of the cornea. A deficiency in these nutrients can lead to corneal issues, affecting transparency and overall eye function.

  • Antioxidant Protection: Selenium, as an antioxidant, helps protect the eyes from oxidative stress. This is important for preventing conditions like ERU, which can be triggered by inflammation.

  • Vitamin A: While not a mineral, vitamin A is vital for eye health in horses. It is essential for maintaining the health of the cornea, which is the transparent outer layer of the eye. Vitamin A deficiency can lead to night blindness and other vision problems.

Flaxseed oil is often recognized for its potential health benefits in both humans and animals. Likewise, Vitamin C, also known as ascorbic acid, is considered an essential nutrient for many animals, including horses. 

Here are some potential ways flaxseed oil may influence equine eye health:

  1. Anti-Inflammatory Properties:

    • Flaxseed oil is rich in alpha-linolenic acid (ALA), an omega-3 fatty acid with anti-inflammatory properties. Inflammation can contribute to various health issues, including those affecting the eyes. By reducing inflammation, flaxseed oil may support the overall health of the eyes.

  2. Omega-3 Fatty Acids and Vision:

    • Omega-3 fatty acids, including those present in flaxseed oil, are essential for maintaining the structure and function of cell membranes, including those in the eyes. While more research is needed, omega-3s are generally recognized for their potential role in supporting visual health.

  3. Dry Eye Syndrome:

    • Omega-3 fatty acids have been studied for their potential benefits in managing dry eye syndrome in humans. While horses may not experience dry eye syndrome in the same way humans do, providing essential fatty acids, such as those found in flaxseed oil, may help maintain ocular moisture and comfort.

Here are some aspects to consider regarding vitamin C and equine eye health:

  1. Antioxidant Properties:

    • Vitamin C is an antioxidant that helps protect cells, including those in the eyes, from oxidative stress. Oxidative stress can contribute to cellular damage, and antioxidants play a role in neutralizing free radicals.
  2. Collagen Synthesis:

    • Vitamin C is essential for the synthesis of collagen, a protein that is a major component of connective tissues. This includes tissues found in the eyes, such as the cornea. Adequate vitamin C levels support the maintenance and repair of connective tissues.
  3. Immune System Support:

    • Vitamin C is known for its immune system-supportive properties. A healthy immune system contributes to the overall well-being of the horse, helping to prevent and fight off infections that could potentially affect various parts of the body, including the eyes.


For general health and nutritional needs, work with a veterinarian or equine nutritionist to ensure your horse's diet is well-balanced and meets its specific requirements for vitamins and minerals. Remember, while supplements can be beneficial, a well-balanced diet is the foundation of equine health.
