Green Lipped Mussel for Arthritis — Does It Really Work?
What Is Green Lipped Mussel?
Green lipped mussel (Perna canaliculus) is a shellfish native to the coastal waters of New Zealand. It has been used by the indigenous Māori people for centuries, and researchers noticed that coastal Māori communities had significantly lower rates of arthritis than those living inland — sparking scientific interest in the mussel's health properties.
Today, green lipped mussel extract is one of the most popular natural supplements for arthritis and joint pain in the UK. But does the science back it up?
What Makes Green Lipped Mussel Special?
Green lipped mussel is uniquely rich in a combination of nutrients that support joint health:
- Omega-3 fatty acids — including EPA, DHA, and a rare form called ETA (eicosatetraenoic acid) that is found almost exclusively in green lipped mussel and has potent anti-inflammatory properties
- Glycosaminoglycans — including chondroitin sulphate, which is a building block of cartilage
- Vitamins and minerals — including zinc, selenium, and B vitamins
- Antioxidants — that help protect joint tissue from oxidative damage
The Clinical Evidence
Several clinical trials have investigated green lipped mussel extract for arthritis, with generally positive results:
A study published in the journal Phytotherapy Research found that green lipped mussel extract significantly reduced pain and stiffness in patients with osteoarthritis of the knee and hip. Another study found improvements in grip strength and walking ability in arthritis patients taking the supplement.
A Cochrane-style review of the evidence concluded that green lipped mussel extract showed promise as a complementary treatment for osteoarthritis, with a good safety profile and few side effects.
Green Lipped Mussel vs Fish Oil
While fish oil is the most well-known omega-3 supplement, green lipped mussel offers some advantages. The ETA fatty acid found in green lipped mussel inhibits both COX and LOX inflammatory pathways — whereas fish oil primarily targets only the COX pathway. This broader anti-inflammatory action may make it more effective for joint conditions.
Additionally, green lipped mussel provides glycosaminoglycans alongside the omega-3s, offering a more comprehensive approach to joint support.
How Long Does It Take to Work?
Most people notice improvements after 4–8 weeks of consistent supplementation, though some report benefits sooner. As with most natural supplements, consistency is key — taking it daily for at least 2–3 months gives the best chance of meaningful results.

Is It Safe?
Green lipped mussel is generally very well tolerated. However, people with shellfish allergies should avoid it. As with any supplement, it's advisable to consult your GP if you are taking blood-thinning medications, as omega-3s can have mild anticoagulant effects.
