✏️ Post #2- vitamins and minerals critical to the metabolic horse.
💡 Today’s topic is Vitamin E 💡
🧲 Why Vitamin E Matters for Horses with EMS (Equine Metabolic Syndrome) 🐴
If your horse has EMS, insulin resistance, PPID (Cushing’s), PSSM, or even just struggles with sore muscles, allergies, or poor performance, it may be missing a critical—but often overlooked—nutrient: Vitamin E.
🌱 Why it matters:
Vitamin E is a powerful antioxidant that protects muscle and nerve cells from oxidative damage. Horses with metabolic challenges often have chronic inflammation, tight muscles, and impaired detoxification—all of which increase their need for antioxidant support.
🧠 Signs your horse might be deficient:
• Muscle tightness, cramping, or soreness
• Poor topline despite adequate calories
• Stumbling, toe dragging, or shifting lameness
• Neurologic signs (poor coordination, odd movement)
• Low energy or dull performance
• Poor immune function
• Dull coat or dry, cracking hooves
• Skin sensitivity, excessive itching, or “allergy-like” reactions
• Exaggerated reactions to vaccines or insect bites
👩⚕️ What the experts say:
Dr. Eleanor Kellon, VMD, emphasizes vitamin E as essential for managing metabolic and neuromuscular disorders in horses. Supplementing with natural vitamin E can reduce oxidative stress, support insulin sensitivity, and improve comfort and muscle function.
Dr. Carrie Finno, DVM, PhD, DACVIM, a leading researcher in equine neuromuscular disease, has demonstrated that even mild vitamin E deficiency may impair the nervous system—sometimes before clear clinical signs appear.
🧪 Why testing is key:
Vitamin E levels can’t be estimated based on diet or symptoms alone. Since Vitamin E is a fat soluble vitamin, over supplementation is possible. A simple serum alpha-tocopherol blood test can determine if your horse is within the healthy range and help guide safe and effective supplementation.
🌾 Why deficiencies are common:
Fresh quality pasture is the richest natural source of vitamin E. But hay loses most of its vitamin E within weeks of harvest—and many EMS horses are kept off pasture to avoid excess sugar, making deficiency more likely.
✅ How to supplement:
Choose natural d-alpha-tocopherol, not synthetic dl-alpha forms. A water-dispersible or micellized formula is ideal for horses with metabolic concerns or digestive challenges but veterinary involvement is recommended. If feeding a powdered version combine with a tablespoon olive oil for best absorption.
✨ Bottom line:
If your horse is metabolic, sore for no obvious reason, neurologically “off,” or showing vague signs like poor coat or itchy skin, vitamin E may be the missing piece. This single nutrient supports the nervous system, immune response, muscle function, and metabolic balance—and it’s often overlooked.
📣 Talk with your vet or equine nutritionist about testing and choosing the right form and dose for your horse.
