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.

Veterinary-strength kidney support for cats and dogs, with a multi-action formula that helps support healthy renal function and long-term kidney health – ideal as early, proactive support for senior pets. High-purity omega-3 from fish oil works alongside chitosan to help bind toxins in the gut, calcium from red seaweed and natural vitamin E antioxidants. Supplied in easy soft gel capsules, it's available through veterinary practices and authorised stockists.

The kidneys filter waste, regulate blood pressure and keep phosphate and calcium in balance. Nutraren Advanced takes a multi-action nutritional approach, combining omega-3, a natural toxin binder and antioxidants to support long-term renal function in cats and dogs.

Binds Toxins in the Gut – 50mg chitosan per capsule, from Icelandic shrimp shells, binds toxins in the digestive tract so they aren't absorbed into the bloodstream, helping to stop the kidneys having to do extra work to remove them.

High-Purity Omega-3 – 207mg total omega-3 per capsule, including 96mg EPA and 62mg DHA from purified fish oil, supports the natural systems that control inflammation, the maintenance of blood pressure and healthy blood flow to the kidneys.

Natural Antioxidant Protection – 10mg natural vitamin E (d-alpha tocopherol) works with chitosan to help keep free radicals in check and maintain renal architecture and function, while also helping to support normal blood pressure.

Highly Bioavailable Calcium – 32mg calcium from the red seaweed Lithothamnium calcareum, whose porous honeycomb structure gives exceptional calcium bioavailability, helping to support renal function.

    My 12 year old cat had dental problems last year and had a blood test. To my sadness a kidney problem was found, the IDEXX SDMA was too high, the Vet suggested switching to Renal food. I tried all renal food companies, none of them suited my cat. She wanted her regular food that she had been eating for 12 years. The vet suggested a good alternative, try Nutraren capsules. Every morning before feeding her food, I put a capsule in her mouth. Exactly one year gone and a few days ago we had another blood test and to everyone's surprise the results were good! IDEXX SDMA was within the normal range! And I can say that over the years the cat's fur has become softer, shinier and she has started to feel better, more active. I am very satisfied with the results! Thank you! We will continue to use these capsules and I recommend them to everyone 100%.

    Pippin was diagnosed with kidney failure, and tried and bought so many diffent renal support food's, but she wouldn't eat any of them, finally put her on a phosphorus binder and she had good day's and bad Days and dreadful constipation, then my vet recommended nutraren and I'm so pleased with the results, she's eating, hardly any tremors, and she's not constipated any more, highly recommend it, pippin will be staying on it.

    My little Chihuahua lovely was diagnosed with 2nd stage kidney disease. We really wanted to try some high quality natural products to help our little girl fight her condition. I can only say that her disease progress slowed significantly thanks to Nutramed & Nutraren. Instead of a prognosis of a couple of months our girl beat the odds thanks to Nutravet products. Please try these wonderful products and see the difference in your pets health and wellbeing. Nutravet have all my families gratitude and China even received her free box of Nutramed too!

    My 15 year old girl has Pancreatitis and was diagnosed as being in kidney failure. Before nutraren she was drinking water non stop day and night and always jumping up for a wee. Now she is stable and settled, not had her bloods done for a while but nutraren has certainly improved her quality of life for certain, thank you.
