New Zealand green-lipped mussels, also known as perna canaliculus, contain a unique and rich combination of more than 21 Omega-3 fatty acids, plus amino acids, vitamins, and minerals including zinc, selenium, and iron. Both scientific and anecdotal research suggests that New Zealand green-lipped mussels may have properties that may provide support for joint stiffness. They may also help support the immune system, brain and heart health.
