KENTUCKY PERFORMANCE PROD Elevate Maintenance Powder

Product overview: Elevate Maintenance Powder provides a readily available source of natural vitamin E to quickly meet essential needs. It’s free from other vitamins or minerals, allowing precise feeding adjustments for horses with high vitamin E requirements. Best for owners seeking a simple, predictable source of vitamin E without risk of imbalances. A potential limitation is the absence of additional minerals; users with broader supplement plans should account for total daily intake.
Horse Health Vita E & Selenium Crumbles

Product overview: This crumble combines vitamin E with selenium to furnish antioxidant defense, immune support, and muscle health. It’s easy to mix into daily grain for consistent intake, making it suitable for active horses in training. Choose this if you want a balanced antioxidant formula with a simple feeding method; be mindful of selenium intake if your horse already receives selenium from other sources.
Best for: Active, training, and endurance horses that benefit from antioxidant protection and an immune boost. Limitation: Crumbles can be less stable in very dusty or moist feeding environments; store properly to maintain palatability.
Vita Flex Pro E & Selenium Supplement

Product overview: Balanced antioxidants with vitamin E and selenium, plus a yeast culture blend to enhance palatability and digestion. Best for horses needing robust antioxidant support and improved nutrient absorption. A potential limitation is the reliance on yeast-based palatability enhancers, which may not suit every horse’s preferences; adjust accordingly.
Best for: Horses that benefit from improved digestion and steady antioxidant delivery. Choose this if you want both antioxidant support and a feeding experience that encourages consistent intake.
Farnam Vita-Min E & Selenium Antioxidant

Product overview: Farnam combines vitamin E and selenium to support muscle cells, immune function, and overall vitality during training and competition. Best for horses performing at higher intensities who need a steady antioxidant supply. Consideration: Some horses may require adjustments if dietary selenium sources are already in use elsewhere to avoid excess intake.
Health-E Vitamin E Supplement

Product overview: High-potency dl-alpha tocopherol powder, designed to support immune, muscle, skin, and nerve wellness. Best for horses needing extra antioxidant support on restrictive diets due to low sugar and starch content. Limitation: Very high potency may require careful dosing to avoid excess intake if multiple vitamin E sources are used in the daily regimen.
Buying Guide: What To Consider When Choosing Vitamin E For Horses
- Purpose and workload: For performance and training horses, prioritize products with balanced antioxidant support (vitamin E and selenium) and palatability.
- Form and ease of feeding: Powders and crumbles offer flexible dosing; pellets or mixes may suit horses that hover on taste preference.
- Ingredient balance: Some products include only vitamin E, while others combine selenium. Check your horse’s current mineral intake to avoid excess.
- Diet compatibility: If your horse has dietary sensitivities (low sugar/starch), choose formulations labeled as appropriate for restricted diets.
- Stability and storage: Some crumbles and powders can degrade with moisture or heat. Store per label directions to maintain potency.
- Veterinary guidance: If your horse has metabolic concerns, thyroid issues, or is on specific medications, consult a vet before adding high-potency vitamin E.
