What are green-lipped mussels?

Green-lipped mussels (GLM), named for the green edge or lip around the shells, are native to New Zealand’s pristine coastline. For centuries, the indigenous Maori people of New Zealand knew of the benefits offered by green-lipped mussels. However, their secret leaked out when scientists saw that they displayed a much lower incidence of joint pain and osteoarthritis than their inland counterparts. This led to intensive research into the health benefits of green-lipped mussels for dogs. Now, senior canines are enjoying the anti-inflammatory effects, too!

Once the wonders of the green-lipped mussel came to light, these mollusks began making their way into many joint supplements. Since 1970, many studies (Trusted Source) have been published on the efficacy of GLM. This ingredient is becoming more popular in pet supplements as well.

Benefits of green-lipped mussels for dogs with joint pain

Decades of research have proven the green-lipped mussel to be a fantastic source of anti-inflammatory components and joint health nutrients. Together, these help ease joint pain associated with aging, help the body protect and repair joints, and may reduce the need for prescription medication.

Acts as an anti-inflammatory

Several studies have found that GLM is effective in reducing arthritis signs in dogs. This magical mollusk is packed full of anti-inflammatory components such as:

  • Omega-3 fatty acids. EPA and DHA are common fatty acids found in fish oil, but GLM has a third one, called ETA. This rare form, unique to GLM, lowers the production of an inflammation-causing enzyme.
  • Vitamins and minerals. Vitamins C and E, zinc, copper, selenium, manganese, and iodine are vital nutrients for your four-legged friend’s joint health.
  • Amino acids. Amino acids are essential for muscle growth and repair, and energy and collagen production. They also have anti-inflammatory effects and are natural pain relievers.
  • Enzymes. Enzymes speed up chemical processes within the body. They’re also involved with the production of connective tissue essential for healthy joints.

Supports joint repair

The green-lipped mussel is a potent supplement ingredient that has been clinically shown to reduce arthritis scores, joint pain, and joint swelling in dogs. Not only that, but it contains other nutrients that limit further cartilage damage while supporting cartilage regeneration. GLM is naturally rich in

  • Antioxidants. Antioxidants combat free radicals, which can cause joint cartilage damage.
  • Glucosamine and chondroitin. Glucosamine helps develop and renew joint cartilage. Chondroitin helps the body maintain fluid and flexibility in the joints.

Reduces the need for medication

GLM may lower your arthritic dog’s need for non-steroidal anti-inflammatories (NSAIDs) (Trusted Source) to manage their pain. Plus, this mollusk can help reduce gastrointestinal irritation associated with long-term NSAID use.

Any known side effects or risks?

Green-lipped mussel supplements are generally considered safe for dogs. But, dogs with shellfish or fish allergies may be allergic to green-lipped mussels. There aren’t studies on pregnant or nursing dogs, so refrain from giving GLM to your dog if they’re pregnant or have pups. Green-lipped mussels haven’t been shown to interact with any other medications or supplements. Right now, there are no known side effects, but more studies are needed to know for sure.

🚨 Always check with your dog’s vet before adding a new supplement to their diet.

How to feed your dog green-lipped mussels

Pet parents can find green-lipped mussels in various treats and supplements for hip and joint health. You may have to try a few to find one your dog likes.

  • Chews. Tasty chews provide an easy way to give your pooch a boost of GLM’s inflammation-fighting nutrients.
  • Powders. GLM in powder form is simple to sprinkle on your pup’s food — and it provides joint health support without extra calories.
  • Oil. The least common way of giving your dog GLM, mussel oil can still provide some joint health benefits. Sometimes, the oil is placed into capsules for ease of dosing.

An interesting result was discovered when studying the efficacy of oil and freeze-dried powder forms of GLM. Although the oil had a higher level of ETA, it was less effective than the powder form in alleviating arthritis signs in dogs. The freeze-dried version contained more joint health nutrients, like complex proteins, glycosaminoglycans, vitamins, minerals, and amino acids.

One study (Trusted Source) researched the efficacy of different routes of administration of the powder. The powder was given to dogs in three ways: sprinkled on top of dry food, manufactured into a treat, or incorporated into a main meal. Although dogs in each group showed improvement, the most improvements came from the group with powder sprinkled onto their food.

👉 When choosing a GLM supplement to add to your dog’s diet, we recommend opting for the powder form.

What’s the GLM dosage for dogs?

Although there’s no exact GLM dosage for dogs, we followed guidelines from clinical trials. In the study linked above, dogs with osteoarthritis signs were given the following amounts of GLM powder:

Dog weight Amount of GLM powder
Less than 55 lbs 450 mg
55 to 75 lbs 750 mg
Over 75 lbs 1,000 mg
