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 tasty kidney support drink for cats that helps support kidney function and maintain normal phosphorus levels, while encouraging cats to drink and take in essential nutrients. Calcium carbonate helps naturally bind phosphorus in the gut, alongside prebiotic fibres, omega-3 and omega-6, taurine, L-carnitine, cranberry and a full blend of vitamins and minerals. The liquid formula is absorbed quickly and efficiently, and is available through veterinary practices and authorised stockists.

Cats with increased renal demands often eat and drink less, which makes daily support harder. Nutraren Advanced Liquid is a clinically proven, tasty drink that combines a natural phosphate binder with essential nutrients, suitable alongside appropriate dietary management under veterinary supervision.

Aids Normal Phosphorus Levels – 5.5mg calcium carbonate per ml aids intestinal phosphate-binding capacity, helping reduce dietary phosphorus absorption and support the maintenance of normal phosphorus balance.

Encourages Intake & Hydration – The tasty liquid format encourages voluntary intake, which may help support daily nutrient consumption and contribute to overall fluid intake in cats with reduced appetite or altered drinking behaviour. It can also be added to renal diets, helping to encourage food intake.

Gut & Inflammation Support – Prebiotic inulin FOS (6mg per ml) helps restore gut microbial balance, while omega-3 (EPA and DHA from fish oil) and omega-6 support the natural systems that control inflammation, which may indirectly ease metabolic stress on the kidneys.

Targeted Nutrients for Kidney Support – Taurine and L-carnitine support cellular metabolism, energy production, heart health and kidney function, dried cranberry supports urinary tract health and a complete blend of vitamins and minerals supports cats with altered nutritional requirements.

Give a total daily volume of 20ml. This amount may be given as single feeding or split into different portions.

Both support kidney health, in different formats. Nutraren Advanced capsules, for cats and dogs, combine omega-3, chitosan, calcium and vitamin E and can be given early as proactive kidney support, including for senior pets who are currently well.

It can be used from 12 weeks of age in any cat with renal disease diagnosed by a vet. If you'd like proactive support earlier, or for a senior cat who is currently well, we'd recommend Nutraren Advanced capsules.
