**** Pro-Kolin: Same great product, new designs: They have recently re-branded, it’s the same great product just with a fresh new look ****

Pro-Kolin replaces Pro-Kolin+. The formulation remains the same. Also see Pro-Kolin Advanced.

Portexin Pro-Kolin contains both probiotics and prebiotics needed to support digestive health in cats and dogs. For pets that experience bouts of stomach upset and loose stools, Pro-Kolin helps soothe the gut lining and firm up faeces. Containing natural 'good' bacteria, Pro-Kolin helps achieve a healthy digestive balance that alleviates discomfort.


Probiotic paste for digestive support

Pro-Kolin contains:


A natural ‘friendly’ bacterium, Enterococcus faecium, which helps to keep the level of beneficial bacteria high and exclude pathogenic species.

Preplex prebiotics

A prebiotic, consisting of fructo-oligosaccharide (FOS) and acacia (Gum arabic), which helps to feed and stimulate the growth of beneficial bacteria.


A natural binding agent which helps to firm up the faeces.


To help soothe the gut lining.

Artificial beef flavoring

To improve palatability and compliance.

Administration Instructions

To administer the correct amount of the product use the handy wheel on the syringe plunger. Rotate the wheel until it is to the right of the number representing the desired quantity to be administered (see diagram below showing the correct and incorrect position for 10ml).

Directions For Use

Pro-Kolin is a highly palatable paste which is available in 15ml, 30ml and 60ml syringes with easy to read graduations, making the product easy to administer.

We recommend using 15ml and 30ml syringes for small to medium dogs and the 60ml syringe for larger dogs.

Give by mouth for as long as considered necessary or as advised by your veterinary surgeon.

Pro-Kolin can be given up to three times daily, depending on severity.

Lloyd suffers from colitis and was prescribed this by a vet when he was a puppy. I have continued to use it as soon as he starts to be unwell and 9 times out of 10 it prevents the need of a visit to the vet.

I always keep a tube of this in the house as my dog is prone to eat anything that comes across her nose, sometimes with unpleasant results! It works well and usually within a couple of days her poo is much better. Wouldn't be without it.

Which pro kolin would you recommend

Lorraine McCorkell

  • VioVet customer since 2013
  • From: Kent, United Kingdom

My 12 year old lab has arthritis and is on anti-inflammatory drugs called rimadyl. As a result of these tablets he gets diarreah quite often and also gets very gassy, which makes him sick. Every so often I have to take him off the rimadyl for a couple of weeks to help his tummy get back to normal. I give him pro kolin paste when he gets diarreah but I see you sell a different kind for long term use. Do you think this would be better for him?

  • VioVet Staff

Protexin Prokolin Enterogenic is recommended for long term use and would be helpful in your dog. If you do find that your dog still has occasional episodes of diarrhoea it is ok to use Protexin Pro-Kolin+ for a short time before switching back to enterogenic.

Expiry date


  • VioVet customer since 2016
  • From: Kowloon, Hong Kong

May i know the expiry date of 30ml and 60ml prokolin?

  • VioVet Staff

This varies from time to time, depending on the stock we have in the building. It is generally a long time; current stocks are all dated in 2018. If you place an order you can leave a note for our staff requesting a date of say, more than 12 months. We will be able to do this, or contact you with what is possible.

Pro kolem


What does pro kolin do to help cure ginivitas

  • VioVet Staff

I would not expect this product to have any direct effect on gingivitis. It should help the digestive process and sometime symptoms which people are aware of and attribute to gingivitis, are in fact related to problems further down in the digestive tract. It is difficult to comment about any particular case without knowing all the details, but I doubt if this alone could cure gingivitis.

22 January 2016 at 3:57pm

Is this suitable for puppies


  • VioVet customer since 2014
  • From: Shropshire, United Kingdom

Can this be giving to nursing puppies and if so from what age can it be given?

  • VioVet Staff

It can be given as soon as they are on solid food, even if they are suckling as well, though you must take into account their small size when deciding on the amount to give.

Can I use this after antibiotics

Deborah Collier

Thanks for your advice.
I'm just looking to run a pro- botic to encourage good bacteria in Buddies gut,due to the long course of antibiotics. He doesn't have diarrhea..... and he can't have FOS... so this product you have mentioned will do this?

  • VioVet Staff

Yes, this product should be helpful in this situation and you can use it.

12 November 2015 at 9:12am

Any FOS?

Deborah Collier

I have a cat with a UTI he's been on antibiotics for 30days.
He has staged 3KD and is a diabetic.
My? Is does your product have FOS in it and would it be safe for Buddy to use? He is between 10/15

  • VioVet Staff

I assume you mean fructo-oligosaccharides and it so, this product does not contain them. Strictly FOS are a pre-biotic, not a pro-biotic, and this contains just the latter. You could try something like Pro-Kolin Enterogenic as an alternative. It contains a good range of all these things and is usually very effective.
