The Green Lipped Mussels transformed my schnauzer's life

I have been buying the Green Lipped Mussel Sprinkles for working dogs from Ace Canine for years and I cannot recommend it highly enough. After my Giant Schnauzer had a significant leg injury, he was really stiff and struggling - This product literally transformed his quality of life. It really is a fantastic product. Delivery is always very quick and communication is great.

Will Flex Green Lipped Mussel Help My Dog?

 You bet !

All the active ingredients used in FLEX jointcare have been clinically proven to support dog joint health in numerous scientific studies.


Is Flex Green Lipped Mussel Top Quality

You bet !

Not all Green Lipped Mussel is equal. Ours comes direct from the Farm/Processor in New Zealand and every batch is independantly certified.

Are Sprinkles Better For My Dog?

You bet !

Pills, capsules and chews contain 150-600mg of Green Lipped Mussel.

Just 1 scoop of Flex yields over 1000mg!

Why do Vets  recommend Green Lipped Mussel extract for dogs?


The reason is because green-lipped mussel is increasingly being recognised as a natural maintenance for joint health and which at the same time provides long term nourishment.  Joint and cartilage function is supported and the production of synovial joint fluid for lubrication is encouraged.

For hundreds of years the coastal Maoris of New Zealand have eaten Green Lipped Mussels as a major part of their diet. The Maoris would harvest the mussels growing naturally on the seashores and would eat them raw. Even though they saw the mussel as an important part of their diet, they did not realise the benefits they were gaining, until settlers in New Zealand later realised that these Maoris had far superior joint health compared to Westerners.

Veterinary surgeons often now promote the addition to the diet of green-lipped mussel as a means  of long-term maintenance of joint health.

Why do our dogs need joint supplements?


Dogs are a species whom we increasingly realise may need additional nutrients to maintain optimum joint and limb health; larger breeds even more so. The increasing use of dogs in sport and leisure activities such as Agility, Flyball, Cannicross, Dog Sledding and  Field Sports is another factor that increases long term wear and tear on the joints.

How do you know if your dog is a likely candidate for joint supplementation and could use green lipped mussel extract for dogs? Perhaps you have simply noticed for yourself an uncharacteristic lack of enthusiasm for exercise, stiffness after rest, awkwardness mounting steps or jumping into the car.  It really makes no difference if your aspirations were to shine in the breed ring, at obedience or agility or simply to enjoy a naturally active life-style with your pet – no doubt you will be looking around for the best way to keep him as comfortable as possible for as long as possible. Remember though that dogs  do still need exercise, not so much as to cause an excess amount of wear and tear but sufficient to keep muscles toned so that they can work to support the joints.


What’s in Green Lipped Mussel that helps dogs?

Unique Omega 3 Fatty Acid - ETA

The Green Lipped Mussel possesses a profile of Omega-3 essential fatty acids which is unique . No other marine or vegetable sources contain anything like as much beneficial Omega 3 oils. Most sources of Poly-unsaturated fatty acids (eg fish oils, flax oil etc) are a mixture of  Omega 3 and Omega 6 oils. The balance between the amount of Omega 3 and 6 consumed is vital because Omega 6 oils can increase inflammation. Our Flex  Green Lipped Mussel extract is rich in Omega 3 oils providing up to 200 times as much per milligram as fish and vegetable oils.

Natural Glucosamine and Chondroitin

Flex Jointcare provides a rich source of all major classes of Glycosaminoglycans (GAGS) which are principle components of cartilage and the synovial fluid found in the joint. These GAGS provide flexibility, elasticity and tensile strength to the articular cartilage. Good joint health can depend on promoting  GAGS content within the joint and surrounding cartilage. As a source of GAGS, Green Lipped Mussel can provide chondrocytes with Chondroitin Sulphate and essential fatty acids which are critical for maintaining joint health.

A  complete joint care formula

Flex Jointcare is the complete joint-care product as it is well balanced with Chondroitin Sulphates 4 and 6, chelated minerals, Glycosaminoglycan GAGS, amino acids and essential fatty acids which together give a synergistic effect that promotes healthy cartilage and provides shock absorbing properties to the joint

How Do I Help My Dog’s Stiff Joints?


Stiff joints don’t discriminate. They affect not only people of all ages, but also  our furry friends, too. If you’re a dog-owner, you want your buddy to eat well, look bright-eyed and playful, and greet you as only a doggy can when you come home. A healthy diet and exercise to help maintain proper weight are the primary ways to help your dog’s stiff joints. A joint supplement such as FLEX jointcare is a really great way too compliment this.

All the active ingredients used in FLEX jointcare have been clinically proven to support dog joint health in numerous scientific studies. We do not add unproven ingredients just because someone else may offer them. All the ingredients in FLEX have been carefully selected, based on the results of research that prove their beneficial effects on the health of your dog's joints.

How Can I Help My Dog’s Poor Hips Or Elbows?


The use of a  supplement to maintain good hip & elbow joint health is recommended; especially in medium and larger breed dogs. Flex Sprinkle has a wide usage in supporting healthy hips or elbows in all breeds.

The natural glycoaminoglycans, vitamins and trace minerals all assist in helping your dog’s hips and elbows by supporting the joint and providing  the specialist nutrition required.


You can read more about healthy hip and elbow structure in our articles  section.....

Joint care and mobility in elderly dogs


As your dog grows into middle and then older age you can expect that life will take its toll on his joints. This is a time whern extra help from supplementation may improve his enjoyment and quality of life.

The production of common compounds that we associate with joint care (Glucosamine, Chondroitin and Hyalauric Acid etc) known as GAG’s (glycoaminoglycans !!) reduces in older and elderly dogs.  

These older dogs therefore become more susceptible to joint problems ranging from just stiffness after exercise, - to more serious issues.

GAG’s  are present in the connective tissues such as  cartilage, tendons and ligaments. Some types of  GAGs attract water molecules, providing cartilage with extra shock absorption properties.

They also have negative electrical charges so the GAG molecules tend to repel each other, imparting a degree of resilience and further protection against trauma and physical shock.

Supplements like Flex are rich in these nutrients and can compensate for your elderly dogs increasing need for them.

Flex Sprinkle is a concentrated granule that is fed with your dog’s normal food. Each pot of Sprinkle contains a scoop that will measure 1300mg of granules, or if you prefer you can use a level small teaspoon instead of the measure, the amount isn’t too critical. There are 38 scoops in the 50 gm pot and 192 scoops in the 250g tub. Feed twice a day if possible by sprinkling onto your dog's food.

Because cheaper Green Lipped Mussel extracts have some of the fatty acids removed they are not as effective at reducing inflammation. Flex Green Lipped Mussel is full strength with no oils extracted. It is supplied direct to us from the New Zealand producer who farms the mussels, processes them and then has every batch tested by an independent body. The mussels are harvested at their peak once per year and the process uses cold extraction and drying technology.

Early days still but 2 of my dogs with eye issues have now been on them for about 1 week and they are showing good signs of improvement. One is a 14 yr old with cataracts and her eyes are already clearer and showing some sparkle. The other suffers with allergy so gets muccus and sore crusty eyes in the allergy season moreso when the pollen comes out, and his eyes are looking alot clearer and less irritable and he is calmer after just 1 week and I am now very hopeful with regular use they will resolve his issue completely. I will be buying them again for sure.

Great service and quick delivery. Website very easy to use. I’ve been giving the flex joint care to my elderly arthritic dog for over a year now and see an improvement in him. He was on yumove advance but I felt it wasn’t doing much for him but I’ll keep him on the flex joint care.

Alycia James 8/4/21

Highly recommended, Flex Sprinkles Jointcare is fantastic!
I’ve bought the Jointcare for both of my dogs. My family has been giving Green Lipped Mussel to our dogs for more than 30 years now and it’s an amazing product. The sprinkles are fantastic and I put it on their food in the morning and no hesitation on eating, even with my fussy boy! One thinks it’s a treat he loves it that much. So much easier than tablets as well. A little goes a long way. Highly recommended.

So helpful and products realy work
I used the carnicare for my cavalier, for may years, sadly hes no longer with me, but he lived to be an ammazing 14, Im sure the carnicare helped his heart, and there is always a real person at the end of the phone should I need help, I still use carnicare for my other Cavalier, and the joint supplements, for my Lhasa Apso when he had a massive back operation, and more recently the hypercillin, now I use that for everything, I clean their eyes and ears with it, and if they ever get a poorly its my go to for them .

As always, Excellent service. Amazing product. Our dog has been taking these Flexi sprinkles for about 3 years now and he is like a puppy again! He's 7 today. Keep up the good work Ace Canine

KA 8/3/21

We were told about this product by a friend (it’s the flex jointcare sprinkles) I was a bit sceptical to be honest, but my big oldish dog was struggling to get up in the mornings so thought it was at least worth a try. And honestly within a week he was back to his old morning self!! We saw a difference in him within a few days really. It’s a shame they don’t sell smaller sample pots as when you’re sceptical you don’t initially feel like trying it (just an idea!) I’ll continue to buy for him, it’s helped his big old joints immensely

Chris Wakeham 14/1/21

Great company very helpful and knowledgeable. After a long chat on the phone I placed an order just before Christmas and it arrived next day. My 2 labradors love the Flex sprinkle and are showing signs of the benefits by moving more freely. Just placed my second order.

Su Brown 1/1/21

You can't beat the best.
My little papillon has been on the Flex Jointcare for a number of years due to various life-long joint and ligament problems. Just recently it was really to prove its worth to me all over again! Buddy has been pretty poorly over a number of months and despite a CT scan nothing conclusive could be found. He was on pretty heavy drugs which I have now weaned him off and onto a natural oil. He was doing really well but then out of the blue started to show signs of distress! Realised that due to him not wanting to eat when he was poorly he had missed out on his Flex Sprinkle for nearly a month! Immediately started him back on a half dose to restart the routine he has been on for a number of years, and to which I have no doubts I owe the fact he is now approaching his 11th birthday and is still with me. Literally within 3 days my little Buddy started to perk up again, and now a week down the line and now back on his full dose of Flex Sprinkle, I have my adored bouncing Buddy back to his old self. I honestly cannot thank Ace-Canine enough for producing this miracle in a tub. I have recommended to so many friends, I have lost count.
