Product Description

  • Proven to significantly improve common lower respiratory conditions like Recurrent Airway Obstruction (RAO) and Inflammatory Airway Disease (IAD).
  • Aleira horse breathing supplements contain the very same vegetarian, algae-derived DHA utilized in human infant formulas making it the only equine respiratory supplement available with this exclusive, concentrated DHA source.
  • Aleira contains an exclusive trio of ground mushrooms long trusted to provide powerful anti-oxidant support, address respiratory inflammation and support the pleural tissues.
  • Aleira is currently patent-pending, ensuring its formula exclusivity as an equine respiratory health supplement and that it has been extensively researched and proven to provide the benefits intended.
  • In addition to the equine respiratory health benefits Aleira provides as a supplement, it has been shown to clinically improve immune mediated conditions like allergies, hives and dermatitis.
  • Aleira pairs well with conventional treatments and provides a non-medical alternative horse breathing supplement in cases where traditional medications are not indicated or well tolerated. 

Aleira®’s patent-pending formula supports optimal equine respiratory health and provides a research backed solution for common lower respiratory ailments in horses like Recurrent Airway Obstruction (RAO) and Inflammatory Airway Disease (IAD).  Omega-3 Fatty Acids have been extensively researched with DHA proving to be the most effective in addressing immune, respiratory and reproductive issues.  Aleira’s exclusive, vegetarian, algae-derived DHA formula is coupled with a proprietary Mushroom Matrix®, Methylsulfonylmethane (MSM) and vitamin C to create the most powerful equine respiratory health supplement available.

  1. It worked for my horse

    Posted by jeff buysse on Sep 28th 2016

    good product. My 19 yr old gelding has chronic heaves, a steady does of aleira on a regular basis has helped him greatly.

  2. horses won't eat it

    Posted by Sharon H. on Sep 16th 2016

    None of my horses will eat it. It smells bad, so that may be part of it. I've tried adding syrup, water and other things to their meal, but then they just won't eat their meal. I am not going to hand shove it down their throats. They have to be able to eat with their meal. None of mine will do that. So, it was a huge waste of money for me.

  3. Really helped! life saver!

    Posted by Carol B on Aug 29th 2016

    My Appaloosa mare developed a respiratory problem last summer and we gave 1 dose of Dex which helped. this year she was much worse and even the full course of Dex did not help at all. i was very upset due to we had lost my mini show stallion to heaves just last summer. Our vet, Joan Tennant, said to try this product. It worked! within 3 weeks her breathing was so much improved, I really couldn't believe it! she is happier, more active and overall seems much better. We did try to reduce the Aleira dose to half, but she started to somewhat regress in a week, so she's back to full dose, at least until this heat and allergy weather gets better. thanks for a great product...so far, so good! Oh yes, she ate it right up mixed in sweet feed...and she can be picky!

  4. Multiple Horses Maintained

    Posted by Unknown on Jul 26th 2016

    I have 4 horses on this product, all for different reasons, and absolutely love it. I have one horse with a cough that has been long standing. His cough is controlled with Aleira and during work, he only coughs once or twice at the beginning instead of throughout. Another horse has severe allergies and if he goes off of this product, he breaks out in hives bad enough he can't be worked. Another horse has an allergy problem as well where he swells through his body during the spring and fall. He hasn't done that since I put him on this product and it has been 2 years. The most recent horse is a young horse that got sick and had a cough that wasn't clearing. I put him on the product and was able to be back in work within a week and the cough started clearing much quicker.

    I haven't had any problems with palatability with any horses that I've put it on. I add a little water with it in their grain and it sticks to the grain.... they eat it no problem.

  5. Agreed. Not Palatable

    Posted by Unknown on Jul 22nd 2016

    Agreed. My horse also will not eat it. Not palatable.

  6. Not palatable

    Posted by Unknown on Jul 13th 2016

    My horse won't eat it. It is not palatable.

  7. New lease on life!

    Posted by Unknown on Jul 12th 2016

    Amazing product! Recommended by vet after my horse suffered a setback from other medication and a new spring allergy season. At the end of his first ninety days I could not believe the recovery he had! I honestly thought before I placed him on this supplement, I was going to lose him. He is on a maintenance plan, at a new barn, outside pasture time increased and living life!

  8. Amazing results

    Posted by Kelly on Jun 29th 2016

    I treated my horse's cough with steroids and it was much better but still evident in the beginning of a ride. After two days on Aleira it is completely gone! I am doing my best to keep the dust down but he is not a candidate for pasture board (suspensory injury plus round bales outside) so this is truly a life saver supplement! I would highly recommend this to anyone with a coughing horse!
