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 joint support for dogs and cats needing extra help, combining multi-pathway ingredients to maintain healthy joint function and support the natural systems that control inflammation. Previously known as Nutraflex, it pairs boswellia with bioavailable curcumin alongside glucosamine and chondroitin, with improvement usually seen within 4–7 days. Supplied in easy sprinkle capsules, it's available through veterinary practices and authorised stockists.

Some pets need more than standard joint support. Nutraquin Advanced, previously known as Nutraflex, takes a multi-pathway approach, combining structural support with two ingredients that work synergistically on the body's normal inflammatory response, for dogs and cats needing additional help.

Multi-Pathway Support – Boswellia extract (AkBoss™, 75mg) and bioavailable Curcumin Complex (Curcuvet®, 30mg) work synergistically to aid the natural systems controlling inflammation, supporting comfort and mobility.

Improvement Usually Within 4–7 Days – The boswellia and curcumin blend helps aid the body's normal inflammatory responses quickly, while the loading period allows the structural ingredients to reach effective levels in the joint.

Cartilage Building Blocks – 505mg glucosamine hydrochloride (99% pure) maintains cushioning and slows breakdown of joint tissue, while 300mg chondroitin sulphate (90% pure) hydrates cartilage and helps protect against cartilage breakdown.

Collagen & Antioxidant Support – 40mg vitamin C supports collagen production and healthy cartilage, tendons and connective tissue and 20mg zinc sulphate supports collagen formation, cartilage health and antioxidant defence.

Frequently Asked Questions

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

Improvement is usually seen within 4–7 days due to the anti-inflammatory action of the boswellia extract. The 6-week loading dose ensures the structural components reach effective levels in the joint.

Yes. Nutraquin Advanced was previously called Nutraflex. Only the name has changed – the formula is exactly the same.

Nutraquin Daily Joint Chews are a tasty everyday chew for dogs, supporting joints, cartilage and tendons with eggshell membrane, boswellia and omega-3.

Nutraquin Fast-Acting Joint Support (formerly Nutraquin+) is a high-strength sprinkle capsule for dogs and cats with stiff joints, combining glucosamine, chondroitin and boswellia, with improvement usually seen within 4–7 days.

Nutraquin Advanced (formerly Nutraflex) is our veterinary-strength formula for pets needing extra support, adding bioavailable curcumin to work alongside boswellia. It's available through veterinary practices and authorised stockists.

It depends on your pet's weight. For the first 6 weeks, give 1 capsule a day up to 10kg, 2 for 10–25kg, 3 for 25–50kg and 4 for 50kg and over. After that, halve the amount for life-long maintenance.

Yes, but if you're looking to maintain healthy joints from an early age, Nutraquin Fast-Acting may be a more cost-effective option.

Nutraquin Advanced is supplied in sprinkle capsules, not tablets, which are easy to give. They can be opened and the contents sprinkled into or onto your pet's food, or given whole.

No, although please be aware that Nutraquin Advanced contains ethically sourced squid and shellfish ingredients, so check with your vet if your pet has an allergy.

    I was recommended Nutraflex for my 13 years old baby, Maya by Emma Hawkins. Maya just had a partial arthrodesis operation and Emma advised that Nutraflex would be good for Maya's recovery. Thank you for everything Emma.

    My boxer Izzy is 11 and a half and had cruciate ligament issues, operations and arthritis, so I wanted to make sure she had the best fighting chance at recovery and pain management. She has been on Nutraquin+ and now Nutraflex, which have all helped her joints so much and gives me the reassurance that I am giving her everything she needs to live a full life in her senior years. She also takes Nutramarin as this helps liver function which is important due to her age.

    We absolutely love Nutravet products! Shamrock started using Nutraquin after he was hit by a car and broke his front legs, that was 8 years ago! I decided to put him on Nutraflex as soon as it came on the market as he's an older boy now and thought he may need extra help with his joints. He's just had a dental, so we also use Nutraplaque to keep his teeth healthy now. He also uses Nutracalm to keep him chilled throughout the year at times. Shamrock highly recommended these products.

    I happened into a vets that sells nutraflex, so we started Spot, our rough coat Jack Russell on it. Very pleased to say we have our bouncy, cheerful, happy dog back, took him to the beach the other weekend - on a lead - he was ecstatic. Thank you so much nutravet, you’ve given us back our dog. Amazing product."
