New Formula - Protexin Acid Ease is now 5 times more concentrated than the original formula, so you only need to feed your horse 100g a day or less. It is also now a powder instead of a pellet as field tests proved it was the more palatable form.

Protexin Acid Ease is now a concentrated formula which is still as delicious and nutritious. Protexin Acid Ease is now a powder formula which has been developed based on customer feedback. New Acid Ease contains the antacids calcium carbonate and magnesium carbonate, as well as kaolin, pectin and L-threonine which together act to buffer excess acid and help protect and soothe the gut lining. The proportion of the high quality fibres – pectin and psyllium have also been increased to create this superior product.

Below are some recent questions we've received regarding Protexin Acid Ease Concentrated Formulation for Horses, including answers from our team.

Give with calmer.

Lynn Lloyd

  • VioVet customer since 2015
  • From: Gloucestershire, United Kingdom

can you give acid ease with a calmer on a regular basis?

  • Non-Executive Director

It should be fine to use these products together. There should not be any sort of adverse reaction and they can both be used for extended periods.

My horse has a nervous stomach and once it starts its hard to stop. It's a little like IBS
I have tried the protexin but it's not working what do you suggest?

  • Non-Executive Director

There are lots of possible causes for what you describe and some are easier to treat than others. I would have to say that if this seems to be a persistent problem then you should get your vet to check things out if this has not already been done. Otherwise I would suggest a good worming dose if this has not been done recently and the product Equitop Pronutrin this can get good results in the situation you describe.

Will this heal a stomach ulcer?


Hello, is the product something that would heal an ulser

  • Non-Executive Director

This product is made to help horses with ulcers or prone to getting them. It certainly should help to allow an ulcer to heal. It is not a licensed medicine however, so it has not been scientifically tested and evaluated and nobody is allowed to say that it will definitely heal an ulcer. I am sure it will be a big help.

Feed with other products


Can you feed protexin acid ease with protexin gut balancer?

  • Non-Executive Director

These products are quite similar and can be given together, though it would probably be adequate to give just the Acid Ease alone.

23 June 2015 at 11:36am

Added to wet feed?


  • VioVet customer since 2013
  • From: East Sussex, United Kingdom

Can this be mixed into a wet feed (speedi beet), or will it lose potency?

  • Non-Executive Director

As long as you only mix it up a short while before feeding, then it is perfectly OK to add to wet feed. This would be the normal way of giving it.
