Comprehensive Nutritional Support for Joints, Cartilage + Bones

Developed with Massey University expertise, BONE+JOINT combines six clinically recognised nutrients, including Green Lipped Mussel, Glucosamine, Chondroitin, and Collagen Type II, to help maintain joint structure, flexibility, and bone strength. Each serving delivers daily support to keep your pet moving freely and comfortably at every life stage.

Supports Healthy Joints & Cartilage

Provides key nutrients that help maintain joint structure, cushioning, and flexibility.

Glucosamine Sulphate and Chondroitin Sulphate work together to nourish joint tissue and support the production of healthy cartilage. At the same time, Collagen Type II provides structural proteins essential for maintaining joint integrity over time.

Enhances Mobility & Activity

Encourages freer, more comfortable movement for active lifestyles.

Green Lipped Mussel provides naturally occurring omega-3 fatty acids and glycosaminoglycans that help keep joints supple and moving smoothly. Combined with Vitamin C, which supports connective tissue strength, this blend helps promote fluid, natural motion in daily activity and play.

Supports Joint Health

Delivers targeted nutrients to help maintain ease of movement and overall joint comfort.

Glucosamine Sulphate helps support the natural formation of cartilage and joint fluid, while Chondroitin Sulphate and Collagen Type II reinforce connective tissues, providing structural resilience for joints under daily strain.

Promotes Strong Bones

Supplies essential vitamins to maintain bone density and skeletal strength.

Vitamin D3 supports calcium absorption and bone mineralisation. At the same time, Vitamin C aids collagen formation, two crucial nutrients that work together to keep bones strong and joints well-supported throughout all life stages.

Maintains Cartilage Health

Provides the building blocks that nourish and support cartilage structure.

Glucosamine, Chondroitin, and Collagen Type II combine to help maintain the elasticity and resilience of cartilage, the tissue that cushions and protects joints during movement, supporting long-term joint performance and comfort.

Suitable for Long-Term Use

Formulated to be gentle, safe, and effective for daily use at any age.

With naturally sourced Glucosamine and Green Lipped Mussel, and essential nutrients including Vitamins C and D3, BONE+JOINT provides everyday nutritional support for joint, cartilage, and bone health, making it ideal for proactive care or ongoing maintenance.

We’ve been using the Tandem BONE+JOINT Chews and Powder for our dog Astra, and the difference has been amazing!

She’s been noticeably more comfortable since we started. Her movement is more unrestricted, and she’s been getting around with ease, even on her busier days out tracking and adventuring!

What’s the difference between the BONE+JOINT Super Chews and the BONE+JOINT Super Blend Powder?

Both contain the same core active ingredients, Glucosamine Sulphate, Chondroitin Sulphate, Green Lipped Mussel, Collagen Type II, Vitamin C, and Vitamin D3, but in different formats.

✨ The Super Chews are a convenient, ready-to-feed daily treat your pet will love, ideal for on-the-go use or picky eaters.


✨The Super Blend Powder is an easy-mix formula designed to sprinkle over meals, perfect for precise dosing or multi-pet households.

Both deliver the same science-backed benefits for joint, bone, and cartilage health, just in the way that best suits your routine.

Can I give the BONE+JOINT with other Tandem Super Foods or Super Blends?

Absolutely! BONE+JOINT is designed to complement the entire Tandem range. Each product targets a different area of wellbeing, so combining them helps support whole-body health.

For example, you might pair BONE+JOINT with Green Lipped Mussel Powder for added joint support, or with PRE+PRO or Pumpkin+ for digestive balance.

How long before I notice a difference?

Most pets begin showing signs of improvement in comfort, mobility, and activity within 3–6 weeks, though results vary depending on age, size, and existing joint condition. Consistency is key; continued daily use provides the best long-term support.

Is BONE+JOINT suitable for long-term use?

Yes! It's gentle enough for daily, ongoing support. The formulation was developed in partnership with Massey University’s School of Animal Science and is safe for long-term use to maintain healthy joints, cartilage, and bones throughout your pet’s life.

Can puppies or kittens take BONE+JOINT?

Yes, BONE+JOINT is suitable for dogs and cats from 12 weeks of age and older. For younger or smaller pets, start with a half dose and gradually build up to the recommended daily amount.

Does BONE+JOINT replace Green Lipped Mussel Powder?

Not at all. BONE+JOINT includes Green Lipped Mussel among several active ingredients. If your pet is already on our Green Lipped Mussel Powder, the two can work together for enhanced joint and cartilage nourishment.

What makes BONE+JOINT different from other joint supplements?

Our formulation was designed, formulated, and tested in partnership with Massey University’s School of Animal Science, combining proven joint-supporting actives with precise nutritional dosing, and backed by over two years of research and development to ensure maximum efficacy and safety.

How should I store BONE+JOINT?

Keep it sealed in its original tin, stored in a cool, dry place away from direct sunlight. No refrigeration required.

What if my pet doesn’t take to it right away?

Every pet has their own preferences! Try offering the chew or powder as a treat, breaking it into smaller pieces, or mixing it with their meal. If your pet is new to supplements, introduce them gradually over a week to allow their system to adjust.

Such a difference in Bentley’s mobility

Palatable for my fussy boys and that’s saying something! These chews make it such a fun and easy way to get supplements in. My older dog, who usually turns his nose up at anything added to his food, now eats these first off the dinner plate every night.

Since starting them, I’ve noticed such a difference in Bentley’s mobility. He’s moving more freely, and visibly more comfortable in his joints.

For my younger pup, Cooper, it’s also the perfect preventative measure to get all the goodness into his diet to help support his bones & joints as he gets older.

Made a meaningful difference

We’ve been trialling Tandem Pet’s BONE+JOINT supplement for just over a year with our two dachshunds, Mila, aged 12 and Minnie, aged 15. Both have had spinal surgery, and Minnie was also diagnosed with immune-mediated bilateral carpal polyarthritis. We were told she’d likely be on steroids for life.

Since starting BONE+JOINT, and with our vet’s guidance, we were able to wean Minnie off steroids completely. Before treatment, she had no use of her front legs; today, she’s moving comfortably and enjoying proper walks again. Mila’s mobility has been consistently good, too, with easier, freer movement day to day. The chews are an easy yes at mealtimes and the powder mixes in without fuss — palatable and simple to stick with long-term.

From our experience, BONE+JOINT has made a meaningful difference to both our girls’ comfort and quality of life.

Difference has been amazing!

We’ve been using the Tandem BONE+JOINT Chews and Powder for our dog Astra, and the difference has been amazing! 💛 She’s been noticeably more comfortable since we started. Her movement is freer, and she’s been getting around with ease, even on her busier days out tracking and adventuring!

I love that these support her joints, cartilage, and bones long-term, helping keep her active and happy. Plus, she absolutely loves them, she goes for her joint chews first at dinner every night! Highly recommend for any dog needing gentle, daily joint support. 🐾

I recommend BONE+JOINT to all my rehab clients

Since starting BONE+JOINT we’ve seen our dog with joint issues move so much easier.

She lives a very active lifestyle on a farm, so it’s important we support her and our other dogs as much as possible to keep their joints as healthy and as mobile as possible as they age.

Since trying it for myself, I recommend BONE+JOINT to all my canine rehab clients, and we wouldn’t be without it in our house.

Being a high energy dog when out of the house, I know these help support his joints and cartilage for all that bush bashing he does.

I’m quite honestly speechless!

If there was one supplement out there I’d recommend to anyone it would hands down be the BONE+JOINT from Tandem.

After our 8 month old pup was diagnosed with hip dysplasia in Feb of this year we were on the hunt for products to support her joints.

Three orthopaedic surgeries later, Pepper has been trialling the BONE+JOINT powder since March and the difference it has made to her quality of life is incredible.

We are so grateful to have been part of the trial, I wish I had more to say but I’m quite honestly speechless. BONE+JOINT has completely transformed her life for the better, & being gentle enough for long-term use means she’s set up for life ❤️

We love the ease of the chews

Old Man Duke is 11years old. He’s getting slower on his walks and when we are done (before adding BONE+JOINT to his diet - but using another well known product on the market) it was a mission to try get him back into the boot of our car. He’s fine to jump in before a walk but afterwards he was always hesitant because he just didn’t have the belief in his back legs to get him in the car. He would often put his paws up and wait for one of us to lift him in.

We love the ease of the chews, and Duke and his brother love the taste. Now, after a walk, Duke is quite happy to jump back in the boot of the car. That has been our biggest tell that this product really is working for Duke.

Thank you, Tandem pet!

It’s our holy grail

Why Tandem BONE+JOINT?

Because it’s been a game changer for Alfie. Sometimes I forget he even had knee surgery just over a year ago. Ever since we started using the Tandem BONE+JOINT supplement, the number of times Alfie has gone airborne to catch the ball - and landed perfectly fine - is amazing.

We’re all about maintenance and prevention now. Tandem BONE+JOINT helps active Alfie maintain joint structure and flexibility. It contains all the essential supplements, minerals, and nutrients needed for bone density, skeletal strength, and cartilage support.

Not to mention, the research behind this product was done in collaboration with Massey University - so in short? It’s LEGIT.

What’s also been awesome for us is the choice between powder and chew formats, which makes mealtimes more flexible.

We swear by Tandem BONE+JOINT, it’s our holy grail and a total necessity in our household.

This will be a permanent staple in our house!

Sadie Mae is a 4-year-old cavalier with mitral valve disease.

Earlier this year, I noticed she was reluctant to hop on and off the bed and slow going up and down stairs. The vet found crepitus in one of her back knees. Because of her heart it was decided not worth the risk sedating her just for X-ray. The suspicion was a partial meniscus tear. I was advised to start a joint supplement. I started her immediately on the BONE+JOINT supplement. Within days she had improved mobility. At her vet review several weeks later, the vet was pleasantly surprised to find the crepitus had resolved.

The powder is so easy to add to a meal. just sprinkle on top and the chews are great as a daily treat. Sadie loves both and always licks the bowl clean

As a pet guardian, the research done behind this supplement gives me real peace of mind I am using something that is backed up by data. This will be a permanent staple in our house!
