Product Information

Synbiotic D-C by Protexin Veterinary gives your dog or cat 2 billion live probiotics alongside a prebiotic in one daily capsule, supporting a healthy gut microbiome for everyday wellness or recovery from illness, antibiotics, or digestive upsets. The gelatine capsule can be given whole or opened and sprinkled over food to suit your pet’s preferences. Soya-free and available in 50-capsule packs, no prescription required.

Health Benefits

  • Supports a healthy, diverse gut microbiome: high-potency probiotic strain helps restore and maintain a healthy balance of beneficial bacteria in the digestive tract
  • Feeds beneficial gut bacteria: Preplex prebiotic (a natural prebiotic fibre blend) nourishes the good bacteria along the full length of the gastrointestinal tract
  • Supports recovery after antibiotics: replaces beneficial gut bacteria disrupted by antibiotic treatment
  • Soya-free formula: suitable for pets with soy sensitivities, unlike some probiotic pastes that contain soybean oil
  • Flexible administration: capsule can be given whole or opened and sprinkled over food to suit fussy pets
  • Once-daily dosing: simple, convenient daily supplement suitable for long-term use

Why Dr Jane Miller Recommends It

“I recommend the Synbiotic DC to almost everyone. You just open the capsule and sprinkle it on food, and dogs and cats eat it without even noticing. It is a month's supply per bottle, and owners genuinely see the difference in stool consistency and overall gut health. Particularly after a course of antibiotics or a bout of gastroenteritis, re-establishing healthy gut bacteria with a pre and probiotic combination makes a real difference to how quickly pets recover.”

Dr. Jane Miller, Veterinarian at Newtown Veterinary Clinic & Vets Love Pets Partner

    Amazing results

    We call it the magic powder. Our little dog was constantly having stomach upsets. Barely a week went by that she needed to go outside in the middle of the night and sometimes up to three times followed by a clean up because of loose stools. Since using the Synbiotic D-C her symptoms have all but disappeared. It’s wonderful for our pet and we get a lot more beauty sleep.

    It works

    It works for my cat. Whether mixed with dry or wet food, my cat doesn't refuse to eat it, and it has also improved his soft stools.

    The vomiting has stopped!

    My cat was a frequent vomited and regurgitator until a new vet suggested this product. He has it every day in his morning meal and now rarely vomits - only if I am not quick enough to make sure he doesn't get hold of an onion bag or my knitting wool!

    Recommended by my dog's vet to settle her tummy. I find they work well for her she doesn't even smell the medicine in her food and she usually picks up any attempt to hide tablets or powders of any kind. So easy to use.

Supporting Your Pet's Digestive Health with Synbiotic for Dogs and Cats

At Vets Love Pets, we're passionate about helping your furry companions maintain optimal digestive health. Our Synbiotic D-C Probiotic Prebiotic Capsules provide a comprehensive approach to gut health for both dogs and cats. These powerful capsules combine beneficial probiotics with essential prebiotics to create a truly effective synbiotic formula that supports your pet's digestive system from the inside out. If your pet struggles with sensitive digestion or you're looking to enhance their overall wellbeing, incorporating a quality synbiotic supplement into their daily routine can make all the difference in their comfort and health.


How Synbiotic Supplements Benefit Your Four-Legged Friends

Understanding the importance of gut health is crucial for every pet parent. Synbiotic supplements work by introducing beneficial bacteria to your pet's digestive tract while simultaneously providing the nourishment these good bacteria need to thrive. For cats and dogs alike, these formulations can help restore balance after antibiotics, reduce occasional digestive upset, and support a healthy immune response. Our veterinary-endorsed Synbiotic D-C capsules are specially formulated to address the unique digestive needs of both dog supplies and feline companions, making them an excellent addition to your pet care routine. With regular use, you'll likely notice improvements in your pet's overall wellbeing, from more regular bowel movements to increased energy and vitality.


Frequently Asked Questions

Synbiotic D-C is a daily probiotic and prebiotic supplement for dogs and cats, used to support a healthy gut microbiome and improve digestive function. It is commonly used after antibiotic treatment to restore beneficial gut bacteria, during or after digestive upsets, and as an ongoing daily supplement for pets with sensitive digestion or recurring gut issues.

Synbiotic D-C and Pro-Kolin+ Probiotic Paste both contain Enterococcus faecium and Preplex prebiotic, but serve slightly different purposes. Synbiotic D-C is a higher-potency capsule (2 billion live probiotics per capsule) better suited to daily supplementation and post-antibiotic recovery. Pro-Kolin+ paste additionally contains kaolin and pectin, which actively firm stools, making it better suited to acute diarrhoea where immediate stool-firming support is needed. Synbiotic D-C is also soya-free.

Synbiotic D-C can be given during antibiotic treatment, though timing matters. Ask your vet for guidance on spacing. Continuing Synbiotic D-C after the antibiotic course ends is particularly valuable for restoring the gut microbiome.

Synbiotic D-C capsules can be opened and the contents sprinkled directly onto food. This makes them easy to administer to cats or dogs that resist taking capsules whole. The probiotic and prebiotic contents remain effective when mixed with food.

Synbiotic D-C is safe for long-term daily use and can be given indefinitely as an ongoing gut health supplement. For post-antibiotic recovery, a course of at least 2–4 weeks following the end of antibiotic treatment is commonly recommended. For acute digestive upsets, continue until normal stools are consistently restored.
