What Is a Green-Lipped Mussel?

The green-lipped mussel, or perna canaliculus, is a bivalve mollusk native to New Zealand. It is found mainly below the intertidal zone at a depth of about 33 feet (10 meters). An extract of this mollusk is said to have medicinal uses.

Most green-lipped mussels can be found in ocean waters of the northern and central parts of New Zealand which feeds on various species of phytoplankton. They are also found in Australia, and are considered an introduced nuisance. The green-lipped mussel is an important commercial mollusk.

It is possible for the green-lipped mussel to reach a length of 10 inches (26 cm). Harvesting length is typically about four inches (10 cm). Juveniles are bright green in color, and adults are purple or black. Commercial adults are green or yellow-brown with brown stripes or spots. All varieties have a distinctive green lip along the inner edge of the shell.

In the 1960s, researchers from the United States and Great Britain conducted studies to test the use of the green-lipped mussel as a treatment for cancer. The mussels had no effect on the cancer, but patients also suffering from arthritis reported improvements in joint symptoms. This lead to later studies of the green-lipped mussel as a treatment for osteoarthritis, rheumatoid arthritis, and asthma. Some of these studies have shown good results, while others show poor or mixed results. Not enough evidence exists for this to be officially labeled as a treatment option.

The healing properties of the green-lipped mussel are thought to come from the polysaccharide glycosaminoglycan. It is available as both a lipid extract and a freeze dried supplement. Other versions of the drug exist but may not be as effective.

During clinical trials, the dose given of the liquid drug was 1,500 milligrams per day. The dose for the freeze dried version ranged from 900 to 1,380 milligrams per day. For patients with asthma, the dose was 200 milligrams per day of the liquid version.

Most people who are interested in using green-lipped mussel extract can do so safely, but there are some possible side effects. Nausea, diarrhea, and liver problems may occur. There is evidence that it causes slow growth or delayed birth of the fetus when taken by pregnant women. Patients who are allergic to shellfish and those with liver impairment should not use these preparations. Anyone wishing to use green-lipped mussel extract or any other health supplement should first consult a health care provider.

The green-lipped mussel, known scientifically as Perna canaliculus, is a bivalve mollusk native to New Zealand. It thrives in the clean, nutrient-rich waters around the country's coastline. This species is distinguished by its vibrant green hue along the edge of its shells, which is the origin of its name.

Green-lipped mussels are renowned for their anti-inflammatory properties, primarily due to a unique combination of fatty acids not found in other marine or plant life. According to research, they contain omega-3 fatty acids, which may support joint health and reduce inflammation associated with arthritic conditions. They are also a source of vitamins and minerals.

Green-lipped mussels can be enjoyed in various forms, including fresh, cooked in dishes, or as a freeze-dried powder used in dietary supplements. In New Zealand, they're often served in restaurants steamed with wine and herbs, highlighting their delicate flavor. Supplements are popular for those seeking the mussels' health benefits without consuming them directly.

Green-lipped mussel farming in New Zealand is considered a model of sustainable aquaculture. The mussels are farmed on ropes suspended in the water, which minimizes environmental impact. This method allows for natural feeding and growth, reducing the need for added feeds or chemicals, and helps maintain the health of marine ecosystems.

Yes, green-lipped mussels are also used in pet health, particularly for dogs and cats suffering from joint issues. The anti-inflammatory properties that benefit humans similarly aid pets. Supplements designed for animals often include green-lipped mussel extract to support joint function and mobility, contributing to overall pet wellness.

Green-lipped mussels are unique due to their green shell edges and the presence of rare omega-3 fatty acids. They are larger than many other mussel species and are endemic to New Zealand. Their cultivation methods and the pristine environment they grow in contribute to their distinctiveness and the sustainability of their farming practices.
