Blister Recycling

At Nutravet, we’re dedicated to the environment and as part of that we’ve partnered with with MyGroup who offer a zero waste solution to reduce the amount of unnecessary landfill waste.

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 daily liver supplement for dogs and cats that helps keep their liver healthy and working well, especially when it's working hard to process medication. Milk thistle, turmeric and high-strength SAMe help the liver naturally cleanse and detoxify while boosting its own natural defences. The easy sprinkle capsules can be given whole or simply sprinkled over your pet's food.

The liver plays an important role in removing toxins from the body and relies on natural antioxidants to protect its cells and function effectively. Nutramarin Advanced is a veterinary-strength formula that combines high-strength SAMe with powerful antioxidants to support healthy liver function, protect liver cells and aid the body's natural detoxification processes.

High-Strength SAMe – Each capsule contains 100mg of S-Adenosyl-L-Methionine (SAMe, 90% pure), a naturally occurring compound with powerful antioxidant properties. SAMe helps protect liver cells from damage and supports the liver's ability to function normally.

Powerful Triple-Action Antioxidants – Silybin (10mg milk thistle complex) and curcumin (50mg, 95% pure) work alongside SAMe to help protect liver cells from free radicals (harmful molecules that can damage cells). Curcumin also supports the production of glutathione, one of the body's most important natural antioxidants. Together, these ingredients help reduce oxidative stress and support the body's natural ability to control inflammation.

Double Enteric-Coated Protection – Nutramarin Advanced is the first SAMe liver product to feature a double enteric coating. This special protective coating helps the ingredients pass through the stomach without being broken down, allowing them to be released and absorbed where they are needed for maximum stability and absorption.

One Formula, Dosed by Weight – The active ingredients are dosed according to body weight (mg per kg), ensuring dogs of all breeds and sizes, as well as cats, receive the appropriate amount. Available in two capsule sizes matched to your pet's weight, the formula is designed for safe, long-term liver support.

Frequently Asked Questions

Curious about how our supplements work, what to expect, or if they're right for your pet?

Yes. Nutramarin Advanced is the new name for Nutramarin+ – the same formula, with new packaging.

Signs can include excessive drooling, vomiting or an upset stomach, increased thirst, yellowing of the skin (jaundice), changes in behaviour, weight loss, loss of appetite and lack of energy. If you notice any of these, speak to your vet.

It depends on your pet's weight. The capsules come in two strengths, 100mg and 200mg SAMe, so larger dogs need fewer capsules – for example, a pet up to 5kg needs one 100mg capsule a day. Follow the administration guide on this page, or ask your vet or stockist which strength is right for your pet.

Nutramarin Advanced comes in easy sprinkle capsules, not tablets. Give them whole, or open them and sprinkle the contents into or onto your pet's food. For the best absorption, give on an empty stomach.

Nutramarin Advanced is designed to support the liver while it works to process medication, by raising its natural antioxidant levels. If your pet is on medication, speak to your vet about using it alongside their treatment.

Yes. Nutramarin Advanced has been developed for safe long-term use, so it can be given every day as ongoing liver support.

Yes, Nutramarin Advanced is safe for both puppies and kittens.

The capsules are for dogs and cats, combining high-strength SAMe with milk thistle and turmeric in double enteric-coated capsules. The chews are a tasty option for dogs only, with milk thistle, curcumin, artichoke and vitamin E.

No. Nutramarin Advanced can be bought over the counter at any authorised veterinary practice or stockist, even if your pet isn't registered there. Use our Find a Stockist tool to find your nearest supplier.

    Jasper had a liver problem over a year ago since taking Nutramarin his health has improved greatly.

    Archie is now 16.5 and has been dealing with some issues related to his liver for the last three years or so. He’s been on Nutramarin since the issues were first discovered and we monitor his liver with blood test every couple of months. While Archie’s starting to really slow down now, he’s still a happy dog who seems to have a good quality of life. I’m confident that without Nutramarin Archie would either be on medication or I might have lost my best friend by now. While Nutramarin doesn’t come cheap, my best friend is worth the investment.

    My border collie, Jazz is 91/2 years old. He was diagnosed with ideopathic epilepsy when he was just over 2 years old and he is also medication resistant. He has been on phenobarbital for the whole of this 71/2 years and potassium bromide for 61/2 years. He also has diazepam, keppra and pexion when he cluster fits. He has been on a herbal mix prescribed by Nick Thompson, a holistic vet, since he started having seizures and until the end of 2019 the medications had been well tolerated. In December 2019 his blood test showed that his liver enzymes were elevated. We reduced his phenobarbital from 120 mg x2 daily to 90mg x2 daily, with the hope that this would be enough to allow the liver to repair. I increased the herbal mix that he was on and also brought in some dietary changes to support his liver. Nick also suggested that I add nutramed to support his liver. In April I read that nutravet had added nutramarin to their products and this was aimed specifically at liver health. After discussions with my vets, I started using nutramarin at the end of April and have been using it ever since. There has been a dramatic improvement in Jazz' liver enzymes. There has been such an improvement that I have no doubts about continuing to use this product. I think the results speak for themselves and the vets are hopeful that Jazz' liver enzymes will continue to improve. Thank you so much nutramarin for producing such a brilliant product.

    I use nutramarin+ on my mini schnauzer who has suffered with pancreatitis and raised liver enzymes and also nutramega. I have been using both these products which were recommended by my Vet, Miss Bendelow for over 7 months now and the difference they have made to my Georgie are amazing. His skin and coat are looking fantastic as he had lost his fur down his back and his liver enzymes are practically back to normal. Thank you so much.
