55 Naf Five Star Respirator
Verified Purchase

By on 12 June 2021

Always turn to this product at this time of the year for my small horse that suffers from pollen sensitivity. It is a great product because it is legal for use by British Riding Clubs. It helps prevent the coughing in warm up and helps keep his airways soothed when doing fitness work. My little Welshman also quite likes the taste of it and never turns his nose up when it is added to his feed.

Below are some recent questions we've received regarding NAF Five Star Respirator for Horses, including answers from our team.

Jessica Copeland

Does this come with something to measure by for the liquid form? The description doesn't say a measurement unit to measure by.

  • VioVet Staff

The 500ml and 1 litre bottles come with a chamber at the top to measure out the liquid within. If the bottle is squeezed then this chamber can be filled to the required volume of liquid.
The 2 and 5 litre bottles do not come with a measuring tool. The doses are measured in mls, I have pasted the guidelines below for reference:

Safe to use alongside bute?


Horse been seen by vet today-respiratory supplement recommended. Is on a sachet of bute daily for arthritis. Will this be ok to use?

  • VioVet Staff

Yes this supplement is perfectly safe to use alongside bute (phenylbutazone).

For a horse that just coughs through a warm up


My horse just coughs everytime I get on and warm up, never heard him cough in the stable, or when he’s being lunged it’s literally just when he gets ridden and it means he needs to pull his head down lots and clear his throat. Would this product be good for him as I am currently using the Kofeve and it doesn’t seem to be making much of a difference to his cough. Thanks in advance

  • VioVet Staff

Respiratory support supplements like this help with allergic/asthmatic/inflammatory airway diseases by supporting normal immune system function. Often horses with this issue are coughing at any time or their respiratory effort is a higher than normal even at rest. If your horse is only coughing on excercise then this can be a structural issues with the airways such as that with the larynx. If the problem is mild then it is worth trying a respiratory supplement like this but you may need to see your vet to ultimately resolve the issue.

Liquid or powder


  • VioVet customer since 2015
  • From: East Sussex, United Kingdom

I have been using the boost liquid at 30 ml per day for four years, I know it helps because I've stopped as a trial previously and symptoms returned. My 20 year old mare doesn't cough but breathes very heavily after a canter, which is worse in summer, over the last few weeks this has become worse (maybe the excessive heat), I have just increased the boost to 60ml per day, is the powder or the liquid better, I'm confused as to which I should be using or both as the powder does advise using the liquid in addition sometimes? I will call vet if it persists but in all other ways she looks and is amazing, and doesn't look anywhere near her 20 years.

  • VioVet Staff

It's great to hear your Mare is doing so well. The NAF Five Star Respirator powder is more comprehensive and contains more ingredients so I would advise using this as the base product you are using if possible. The liquid can then be used as a top up if necessary.
If the breathing issues are consistently on exercise then this can be a laryngeal issue, I would recommend contacting your vet if it doesn't improve on the powder or if the problem worsens.
