Arenus Aleira Optimal Respiratory and Immune Support for Horses is a daily, non-medicated supplement designed to support respiratory health, immune function, and inflammation in horses with chronic respiratory issues, allergies, hives, and skin conditions. Its patent-pending formula features algae-derived DHA, recognized for its superior bioavailability, alongside antioxidant-rich mushrooms, Vitamin C, and MSM to help horses breathe easier and perform better without relying on steroids.
Unlike traditional Omega-3 supplements that use fish oil or flaxseed, Aleira delivers DHA from purified, vegetarian algae, the same quality used in human infant formulas, ensuring safe, effective absorption. Whether your horse is dealing with Recurrent Airway Obstruction (RAO), Inflammatory Airway Disease (IAD), or seasonal allergies, Aleira offers a natural, research-proven alternative to help restore respiratory balance and wellness.

Feed the recommended daily amount.
Reduce to 50-75% of the full dose depending on the horse's needs. Increase temporarily during seasonal respiratory challenges.
Store in a cool, dry place with the container sealed tightly.
Supports Healthy Breathing: Helps manage symptoms related to RAO, IAD, EIPH (bleeders), and other performance-limiting respiratory conditions.
Reduces Inflammation Naturally: Anti-inflammatory properties of DHA, MSM, and mushrooms aid in respiratory tissue recovery and comfort.
Steroid-Free Solution: Safe for long-term use, Aleira offers an alternative to conventional medications without side effects.
Improved Immune Response: This powerful antioxidant combination boosts immune health and aids in the management of dermatitis, hives, and skin allergies.
Veterinarian Recommended: Trusted by equine vets across the U.S. to manage both acute and chronic respiratory conditions.
Highly Palatable: Flavored with peppermint and peppermint extract for easier acceptance, even by picky eaters.
Aleira is the only equine respiratory supplement using algae-based DHA—the most absorbable and safe form of Omega-3 for horses. Fish oil sources can carry heavy metal risks and aren't efficiently processed by herbivores. Flaxseed-based ALA must convert to DHA and EPA, but horses convert poorly, leading to limited benefits.
Including a proprietary mushroom matrix further elevates Aleira’s effect, helping reduce airway inflammation and support pleural tissue health. With clinically tested results, Aleira is trusted by veterinarians and performance horse owners to manage conditions without pharmaceuticals.
