55 Great product.

Use this to stop diarrhoea from PPID medication, on bets advice, I need to use daily and it works. If I stop using it then in a couple of weeks my mare is in a mess again. Tried a cheaper brand at double the dose and was only half successful, won’t be changing again! Only need 3/4 measure a day with Protexin. Only thing I’d improve is shape of pot and spoon so it’d be easier to get out!

My irish cob horse had colic twice in one year which I felt was gut pain related. I have given her Protexin Gut Balancer and no issue for 15 months. She seems a lot happier so far.

Q & A

Below are some recent questions we've received regarding Protexin Gut Balancer (Bio-Premium) for Horses, including answers from our team.

Lasting effects


How long does 1 scoop take stay in the horses system? Only asking as I usually fees around the same time every day but they have now gone out for summer... so if it is fed at a slightly different time through the day will this make a difference?

  • VioVet Staff

Changing the time of day of dosing should not make a significant difference to the effect of the supplement. Ideally the dose should be given at the same time of day each day, but if you wish to move this time then you can do this without issue.

How long will a tub last for?


How many scoops is in each of the tubs?

A 400g tub will last 40 to 80 days
A 700g tub will last 70 to 140 days
A 3.5kg tub will last 350 to 700 days
A 7kg tub will last 700 to 1400 days

Stress use
10 - 20g (1 - 2 level measures) added to the daily food.
A 400g tub will last 20 to 40 days

Is this ok for a horse with previous laminitis?

  • VioVet Staff

Generally you want to avoid high sugar supplements if your horse is prone to laminitis. This supplement has a low sugar content and so is safe to use.

Expiry date?

Zoe Blaauw

  • VioVet customer since 2017
  • From: Surrey, United Kingdom

If I feed 10g twice a day, the 7kg would last a year, is the expiry longer than that?

  • VioVet Staff

Hi Zoe,

Thank you for your query.

Please be advised our current stock of Protexin Gut Balancer has an expiration date of 01/20 so you would have plenty of time to feed daily for a year. I hope this can be of some help to you, but if we can be of any further assistance in the meantime please let us know at [email protected].

Usage length

Victoria Lane

If i feed two scoops of this a day, how long will a 700kg tub last for?

I.e how big are the scoops?

  • VioVet Staff

A scoop is 10g so at a rate of 2 scoops a day the 700g tub would last 35 days and the 7kg tub would last 350 days.

Hind gut

Aimee Holt

  • VioVet customer since 2017
  • From: , United Kingdom

Hi there

I already feed acid ease, can you tell me what the difference is in product? I think my horse has a hind gut issue. I'm also already feeding yeasacc. Anything else you could recommend?



  • VioVet Staff

Acid Ease acts to protect and soothe the gut lining where the Gut Balancer will help restore the normal balance of microbes in the gut. This balance is very important to maintain efficient digestion and absorption of nutrients. Gut Balancer is the product I would recommend if you are concerned about hind gut issues. You can safely feed this alongside Acid Ease.

Horse eating poo


  • VioVet customer since 2017
  • From: Bedfordshire, United Kingdom

My horse has been noted to be eating poo - he's turned out 24/7 and given extra haylage over the past couple of months through the winter with 2 small hard feeds a day. Would this be worth trying as the poo eating suggests maybe some gut issues?

  • VioVet Staff

Good bacteria in the hind gut of a horse help to break down food, manufacture certain essential vitamins and keep "bad bacteria" at bay. If the hind gut has gone into dysbiosis and the balance of good bacteria to bad bacteria has been compromised you are right that a horse may eat poo to re-establish the correct balance of bacteria in the gut. Of course there are exceptions to this rule but using a probiotic is a good place to start. Protexin Gut Balancer would be the ideal product to use here so I would certainly give it a try.

Haylage bum


Horse is on haylage and has solid pooh but lots of liquid comes out at the end. Her bum is very dirty. Will this help settle her?

  • VioVet Staff

Yes, probiotics such as this should help to firm up her droppings. You could also try feeding a mixture of hay and haylage so that the forage she is getting is not so rich. This would also be better for her teeth since some horses can be prone to developing peripheral caries on haylage only.

My daughters pony seems to becoming a bit grumpy when girthing up , when brushing belly etc

Grumpy behaviour

My daughters pony is becoming more grumpy and sensitive when brushing his underneath, girthing up and when ridden when riders legs are on him. He's recently started to do a little buck occasionally when legs go on. We've had him over a year and he's always been fine. His belly looks bloaty , although his droppings are fine. He's also grinding his teeth on door which is a new behaviour. He's turned out in day, in at night and has good diet. He's competing most weekends and all his tack etc fine. Wondering if he could have a sensitive Tummy and if this product could help?

  • VioVet Staff

It is possible that he has an uncomfortable abdomen due to a digestive condition and that this product will help. However it is too difficult for me to say how likely this is. There might be many other reasons for the observations you have made and they might well need a different treatment. Ideally you need a good horse vet to spend some time examining him and perhaps do some faecal tests to try to establish what is wrong. There will be no harm trying this product, but it might not help.
