Respiratory supplements: what’s on the market?

They have all been specially formulated to support the respiratory system from within and come in a variety of forms, so there’s something to suit every fussy horse.

Best respiratory supplements for horses

NB: Cost per day has been calculated using the maintenance measure for a 500kg horse in light work (where there was variation) and the RRP of the smallest available tub. Some products require you to feed more in certain situations, which will increase the cost per daily measure, while buying a larger tub will likely decrease it – these costs per day are a guide only.

How to choose the best respiratory supplement for horses

Look out for common ingredients that are found in respiratory and breathing supplements for horses, which include…

• herbs — many of which are known for soothing properties
• anti-oxidants, such as vitamin E, which protects against free radicals

Consider the form the supplement takes – breathing supplements for horses can come in liquid or powder forms. Your horse may have a preference to one over another, which could make all the difference as if he won’t eat it, your horse won’t receive the benefit.

Cost is another consideration – we’ve calculated the daily cost of all the supplements featured in this guide to help you compare them easily. To make it as comparable as possible, we’ve used the smallest tubs available, but you’re better off buying a larger volume of supplement if you can as the daily cost can become significantly lower.

Do I need a breathing supplement for my horse?

There is always a challenge to your horse’s respiratory system — in the summer it’s pollen particles, while increased time in the stable in the winter exposes horses to more dust from forage and bedding.

There are a number of management practices you can put in place to reduce their exposure, but the best respiratory supplements for horses can also help to maintain healthy and clear airways, support the lungs’ natural defences, while also providing a soothing effect.

Coughing can be a sign of respiratory disease so if your horse develops a cough it’s wise to consult your vet.

Can I compete if I am giving my horse a respiratory supplement?

If you compete with your horse then it is important you make sure any supplements – respiratory supplements or otherwise – you use do not contain any prohibited substances. You can also look for the BETA NOPS logo, which shows that the manufacturers are part of a scheme that prevents use of naturally occurring prohibited substances.
