55 Excellent product
Verified Purchase

By on 20 November 2020

We gave her the 10 day loading course and then reduced within 5 days she was a lot better lively in herself and a lot less of a wheeze. She now has no wheeze and she is a lot better.

55 Made a real difference - can't stop using it!
Verified Purchase

This really works. My cob wheezes very badly and has allergies. Rao symptoms. Much worse when his head was down. Affected him ridden and out in field. Before I got vet I tried this. Within three days it made a big difference and my friend noticed as we were riding out. If you stop using it you'll soon notice it within a few days! I found it much cheaper on viovet too. Strongly recommend this product! Don't think he's massively keen on the taste but it's not a large amount and he soon got used to it.

55 Great stuff!

My gelding was coughing due to dust and spores whilst being stabled more in the winter. We couldn't get through a schooling session without a few coughing fits. Only downfall is if you order bigger bottles you need to find a scoop or something to measure the quantity. Other than that it's definitely worked for my horse. Top stuff.

35 Stable cough

Took the whole bottle to work, plus the horses were turned out on grass the first week of using it. I personally find that Coffless works much better, but it has been unavailable all winter.

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?

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.

Safe for broodmares ?


Is the NAF Respirator Boost safe for broodmares - foal at foot and back in foal again. Thanks

  • VioVet Staff

Yes this product is perfectly safe for pregnant and lactating horses, including your broodmare.
