As a result, customers can now send their empty blister packs back to us for recycling. The empty blisters are sent for separating, and the plastic and aluminium are both recycled separately into various products and other manufacturing processes.

Some key points about why we’re working with MyGroup:

  • Globally, health and veterinary care waste accounts for over 4% of all CO2 emissions and 1-2% of all urban waste.
  • MyGroup recycle every material into alternative products so no waste is created from any part of the packaging.

A fast-acting probiotic paste for dogs and cats that helps firm up loose stools and supports a return to normal digestion during digestive upsets. Natural kaolin clay absorbs excess water, while a high-strength probiotic (4 billion CFU per 2ml), prebiotics and sweet basil extract help rebalance the gut and soothe the gut lining. The tasty paste comes in an easy-dose syringe for simple, hassle-free use.

As part of our Advanced range, it's available through veterinary practices and authorised stockists – use our Find a Stockist tool to find your nearest supplier.

Nutrabio Advanced provides fast, short-term support for dogs and cats during digestive upsets, helping stools return to normal within 1–2 days. Its veterinary-strength formula combines probiotics, prebiotics and kaolin to help firm loose stools, restore the balance of good bacteria in the gut and support digestive recovery.

High-Strength Probiotic – Each 2ml notch delivers 4 billion CFU (live beneficial bacteria) of Enterococcus faecium (DSM 10663 NCIMB 10415). A protective coating helps the probiotic survive stomach acid and reach the gut, where it helps restore the natural balance of good bacteria.

Kaolin to Bind and Firm – Kaolin clay (100g/kg) helps bind toxins in the digestive tract so they can be removed naturally. It also absorbs excess water, helping to firm up loose stools and return them to a normal consistency.

Feeds the Good Bacteria – Prebiotics FOS and MOS provide food for the good bacteria in the gut, helping them grow and thrive. Together with the probiotic, they help restore a healthy gut balance and support normal digestion.

Easy, Stress-Free Dosing – Sweet basil extract, unique to Nutrabio, gives the paste a naturally appealing taste, making it easier to give to dogs and cats. The easy-to-use syringe has clear dosage markings and weight-based loading and maintenance doses, helping owners give the right amount every time.

    My dog loves nutrabio. When we need to use it he sits and salivate. It works really well and is so easy to give as he enjoys it so much. We have tried other pastes for upset tummies but nutrabio works best for our Boxer dog.

    These two are aged 17 months and 10 years old and have both got very sensitive tummys so we use nutrabio many times. What an amazing product it is. I would recommend this to all my dog mummy and daddys, it’s an amazing product - 5 stars from me.

    This is a superb product for upset tummies. I have 3 Chihuahuas and 3 cats so always have a tube in. I used my last tube for this little fella Bo. Had his tummy put right in no time!

    My 14 year old Lab X suffers from bouts of colitis, and the vet recommended nutrabio by way of a maintenance stand by. After her last bout I started with the paste, and by the next day she was better. The paste is pleasant smelling and the dog loves the taste. It supports her digestive system.

    nutrabio is brilliant stuff. My GSD had a sensitive tummy for 11 days. I was given nutrabio from our vet and it stopped after just 1 dose.

    nutrabio is fab stuff. Thanks to Ayres Vets in Cramlington. When our Collie had a bad stomach from eating a sour apple, they gave us nutrabio and she was back to normal in a day. It’s definitely worth buying a tube and putting it away just in case.
