Your duties as a horse owner or equestrian don’t end at changing horseshoes and buying fly repellents; they extend to more intricate and internal issues like disease control and prevention. Several kinds of diseases affect horses, and some of the most worrisome kinds affect the respiratory system. They usually manifest as inflammation, heaving, coughing, and lung bleeding and even influenza. That is why it’s essential to invest in one of the best respiratory supplement for horses, along with proper clinical treatment.

The best respiratory supplement for horses were designed to soothe your horse and help it breathe clearly and more evenly.  They have lots of antioxidants and other great minerals like calcium and potassium. The best respiratory supplement for horses will nourish your horse, protect its immune system and boost performance at the same time.

What to look for in Respiratory Supplements for Horses

Respiratory supplement for horses were made to assist prescribed medicine. When horses are afflicted with a disease or infection, supplements can serve as a sort of backup treatment to help the horse recover faster, breathe more clearly and perform better. Although they are not quite reliable enough to replace prescribed medicine for animals, they can be quite effective when combating respiratory diseases and irritation.

The Ingredients

They should, in theory, help your horse breathe better and should consist of a blend of antioxidants, vitamins and herbs. Typically, you should expect ingredients such as

  • Omega-3 fatty acids
  • Argine
  • Vitamins C.
  • Rosemary
  • Triphala
  • Astragalus
  • Camu Camu
  • Cranberry
  • Bilberry fruit
  • Forsythia fruit
  • And several others.

Most respiratory supplement for horses are all-natural. They consist of natural antioxidants and vitamins that strengthen the immune system, as well as reduce inflammation, soothe allergic reactions and ward off illness. Although most respiratory supplements are all-natural, some supplements don’t limit their ingredients to just herbs and fruits alone. They aren’t as popular as the all-natural ones, but they can be just as effective.

They should come in Powders, Syrups or Concentrates

Any respiratory supplement for horses that is worth the money you spend buying it should come in concentrates, syrups, pellets, pastes or some form of water-soluble powder. Supplements in these forms are easier to keep track of, store and use whenever needed. Horses and equestrians prefer these types of supplements because they taste better and can be integrated easily into the horse’s diet.

Watch out for the smell

A horse will decide to consume or refuse a supplement based on the smell alone. Horses can be suspicious, and they won’t eat anything that they aren’t comfortable with. A lot of respiratory supplement don’t have a pleasant smell. They can stink up entire barns and stables and can be unpleasant for both horse and equestrian.

The smell shouldn’t be a deal-breaker. There are effective ways to get past your horse’s keen sense of smell, but it’s often better to just opt for something less smelly. The smell of the supplement does not connect directly to its efficacy or anything else. But if it’s possible to get something that will keep your animal healthy and that smells nice, then that should be what you should spend all your hard-earned money on. Any respiratory supplement for horses that your equine refuses to take will be a waste of resources.
