The green-lipped mussel, from which PCSO-524 is extracted through a patented process, is farmed and harvested exclusively from the pristine waters of New Zealand's Marlborough Sounds. This unique environment and aquaculture contribute to the stabilized marine lipid extract's natural anti-inflammatory properties. PCSO-524 is the only known omega-3 marine lipid extract to contain a total of 30 healthy fatty acids including DHA and EPA.

Omega XL is a bestselling omega-3 supplement that contains the patented stabilized marine lipid extract PCSO-524 derived only from the New Zealand green-lipped mussel. Omega XL, manufactured exclusively by Great HealthWorks, is the only omega-3 fish oil supplement available in America that contains the potent PCSO-524 marine lipid extract.
