Vitamin E for Horses: Deficiency, Neurologic Risks, and How to Supplement Correctly

This episode explains why vitamin E is a critical nutrient for equine muscle and nervous system health and why deficiency is increasingly common in modern management. It covers how vitamin E functions as a fat-soluble antioxidant that helps neutralize free radicals and reduce oxidative stress, especially in metabolically active tissues like muscles and nerves. The script highlights that fresh pasture (alpha-tocopherol) is the best natural source, while vitamin E degrades rapidly in hay over time, putting stalled, dry-lot, and limited-turnout horses at risk. It discusses deficiency links to neurologic and muscle issues including ENAD/EDM in young horses and EMND in adults, and outlines supplementation basics: natural D-alpha tocopherol vs synthetic DL forms, water-dispersible options, common dosing ranges, and the role of blood testing (targeting roughly 2–4 µg/mL, often ~3).00:00 Why Vitamin E Matters00:42 Oxidative Stress Basics02:28 Free Radicals in Metabolism04:53 Vitamin E Protects Muscles Nerves05:27 Natural Sources Pasture vs Hay07:16 Neurologic Disease ENAD EDM09:23 Adult Signs and EMND10:07 Choosing a Supplement Form11:36 Dosing Safety and Blood Tests14:11 Key Takeaways and Products15:32 Wrap Up
