New Zealand green-lipped mussel for dogs and cats is a natural source of omega-3 fatty acids, glucosamine and chondroitin. These nutrients provide nutritional support for healthy joints, comfortable movement and everyday mobility, particularly for senior, active or larger pets.
What is New Zealand green-lipped mussel?
Green-lipped mussel, or Perna canaliculus, is a shellfish native to New Zealand. It takes its name from the distinctive green edge around its shell.
And that “New Zealand” part matters. Perna canaliculus is endemic to New Zealand, meaning it naturally occurs there. Genuine NZ green-lipped mussel is not simply an ordinary mussel wearing a fancy green hat.
PetWell uses premium, human-grade New Zealand green-lipped mussel to ensure your pet receives the real ingredient and its naturally occurring nutritional compounds.
Why is New Zealand sourcing important?
New Zealand has established controls for its commercial shellfish industry. Commercially harvested shellfish must come from classified growing areas, supported by monitoring and testing programs.
Choosing clearly identified New Zealand Perna canaliculus gives pet parents greater confidence in the species, origin and traceability of the ingredient. When comparing supplements, check that the label specifies New Zealand green-lipped mussel, rather than simply “mussel powder”.
What are the benefits of green-lipped mussel for dogs and cats?
Green-lipped mussel provides a broad mix of nutrients that can support joint structure, flexibility and comfortable movement. It contains omega-3 fatty acids, including EPA, DHA and ETA, alongside naturally occurring glucosamine, chondroitin, amino acids, antioxidants, vitamins and minerals.
These nutrients may help support:
- Healthy cartilage and connective tissue
- Comfortable joint movement
- Flexibility and everyday mobility
- A balanced inflammatory response
- Active, ageing and hardworking joints
Research involving dogs with osteoarthritis has found that green-lipped mussel preparations may support improvements in mobility and discomfort when compared with a placebo. You can read the dog study here.
Research in cats is more limited, but a feline diet containing green-lipped mussel alongside EPA, DHA, glucosamine and chondroitin was associated with improved measures of mobility.
Green-lipped mussel is nutritional support, not a cure or replacement for veterinary care.
Which dogs and cats may benefit?
Green-lipped mussel may suit senior pets, active or working dogs, large breeds and pets beginning to show changes in movement. It can also provide ongoing joint nutrition for younger adult pets.
Cats are masters at hiding discomfort, so their signs can be surprisingly subtle. Watch for:
- Hesitating before jumping
- Sleeping more than usual
- Stiffness after rest
- Avoiding stairs or high surfaces
- Reduced grooming or play
- Becoming grumpy when handled
If these changes appear suddenly or persist, book a veterinary check-up to rule out injury or illness.
How can I give my pet green-lipped mussel?
Green-lipped mussel can be offered as a powder mixed into food, as a freeze-dried whole-food treat or as part of a complete joint-support blend. Follow the recommended serving guide for your pet’s weight and use it consistently.
PetWell offers three easy options:
- New Zealand Green-Lipped Mussel Powder
- Freeze-Dried NZ Green-Lipped Mussels
- MOBILITY Joint Supplement, combining green-lipped mussel with MSM, turmeric, Boswellia, rose hip and other supportive ingredients
Is green-lipped mussel safe for pets?
Green-lipped mussel is generally well tolerated when given according to the product directions. However, it may not suit pets with a shellfish allergy or sensitivity.
Speak with your vet before introducing a new supplement if your dog or cat has a medical condition, takes medication, is pregnant or is recovering from surgery.

FAQ's
Can cats have green-lipped mussel?
Yes. Green-lipped mussel can provide nutritional support for joint health and mobility in cats. Always use a product suitable for cats, follow its weight-based serving guide and consult your vet if your cat has a medical condition.
How long does green-lipped mussel take to work?
Results vary between pets. Some pet parents notice changes in comfort or mobility within several weeks, while others may need longer. Green-lipped mussel works best when given consistently according to the product directions.
Is green-lipped mussel better than fish oil?
