Wondering how to choose a green lipped mussel supplement for dogs? Vet Carol Bryant talks us through the benefits & considerations of GLM.

Quick takeaway: Did you know that more than half of pet parents now include at least one supplement in their pup’s daily routine? Recent data from the American Pet Products Association (APPA) shows that Green Lipped Mussel Supplements for Dogs (GLM supplements) are among the most popular, reflecting a growing awareness of canine joint health, and a desire to support aging or active dogs among pet parents. In this helpful article by experienced vet Carol Bryant DVM, we learn about GLM supplements for dogs, including sourcing, formulation, supporting ingredients, and important factors to consider before giving your dog Green Lipped Mussel.
Over the past 5 to 10 years, green lipped mussel (GLM) has become a popular supplement for dogs. Once considered a niche ingredient, GLM is now one of the fastest-growing ingredients in canine mobility supplements. However, just because a product contains GLM doesn’t mean it is vet-reviewed or properly sourced.
There are three key differences to consider when selecting a green lipped mussel supplement for your dog: sourcing, formulation, and supporting ingredients. Whether you share life with an energetic athlete, a large breed prone to joint stiffness, or a senior dog showing signs of aging, it’s important to choose a high-quality GLM product that may help support mobility and overall well-being.
When choosing a green lipped mussel supplement to support your dog, some key factors to consider include:
This guide will help you choose a high-quality green lipped mussel supplement for dogs that may help support joint health and comfort.
It’s helpful to understand what green lipped mussels are and how they function in a joint supplement for dogs. GLM is a species of mollusk native to New Zealand. Scientifically known as Perna canaliculus, GLM has long been harvested among the Maori people, who value its nutritional profile. Green-lipped mussels are also used in human joint supplements.
GLM is appreciated for being naturally rich in omega-3 fatty acids (including EPA, DHA, and eicosatetraenoic acid or ETA), as well as glycosaminoglycans (GAGs), naturally occurring compounds found in healthy joint tissue and cartilage. It’s also a natural source of minerals like zinc, magnesium, and selenium.
Some studies suggest that when used consistently, GLM may help support joint function and comfort. Chewable formats may make daily administration easier for some dogs..
When used consistently as part of a daily routine, green lipped mussel supplements may:
As always, results may vary depending on your dog’s age, activity level, and health status. GLM should be used as part of a comprehensive joint care routine with guidance from your veterinarian.
With the growing popularity of green lipped mussels, the market has many options with varying quality. While some products include premium New Zealand-sourced mussels, others may use lower-quality extracts or unspecified sources. Here’s what to consider:
Look for GLM sourced from New Zealand, where quality standards and sustainability practices are strict. Avoid products that list “mussel extract” without providing sourcing information.
Chewable supplements are often easier to administer than powders or capsules. Choose a form your dog will readily accept.
GLM may work well when combined with other joint-supporting ingredients, such as glucosamine, chondroitin, turmeric, Boswellia, and omega-3 fatty acids.
Products that are transparent about formulation and manufacturing often include veterinary input. This can help build trust and credibility.
Joint supplements generally require consistent, long-term use to provide benefits. Follow manufacturer instructions and consult your vet for tailored guidance.

If you’re considering a supplement with green lipped mussel, one example is PetLabCo. Joint Care Advanced Chews for Dogs. This vet-reviewed formula features GLM sourced from New Zealand and includes additional ingredients commonly used to support joint health.

The soft chews are flavored with hickory smoke and salmon, which may appeal to many dogs. They’re suitable for dogs 12 weeks and older and are manufactured in the USA with globally sourced ingredients. Dosing is based on your dog’s weight:
As with any supplement, it’s best to check with your veterinarian before beginning a new routine, especially if your dog has dietary sensitivities or is taking other joint products.
Is green lipped mussel suitable for dogs?
GLM is generally well-tolerated by most dogs when sourced from a reputable supplier. Always consult your veterinarian before introducing any new supplement. Dogs with shellfish allergies should avoid GLM.
How long does it take to see results?
Joint support typically requires consistent use. Some pet parents may observe changes within 30 to 60 days, with full benefits often seen around 90 days.
Can GLM be used with other joint ingredients?
Yes, GLM may be used alongside other ingredients such as glucosamine or omega-3s. Many comprehensive joint formulas combine these compounds.
Does it replace other joint supplements?
GLM does not replace all joint supplements but may complement them. Speak with your veterinarian to determine if a GLM supplement is appropriate for your dog.
Joint health plays a vital role in your dog’s quality of life. Green-lipped mussel may offer a natural, nutrient-dense option for dogs needing joint support. Not all supplements are equal, so use the criteria in this guide to help select a high-quality option.
One example is PetLabCo.’s Joint Care Advanced Chews, formulated with New Zealand-sourced GLM and additional joint-supporting ingredients. Always speak to your vet before starting any new supplement.
