  • Sustainable Sourcing: Certified by the Marine Stewardship Council (MSC), this krill oil originates from a rigorously regulated, well-managed, and sustainable Antarctic fishery.
  • Advanced Absorption: Delivers omega-3s via phospholipids, forming liposomes that efficiently transport fatty acids directly to your body's cells, a key advantage over standard fish oils.
  • Enhanced Purity: Features Superba2 krill oil, purified through a patented process to remove salts, minimizing fishy aftertaste and odor, and achieving over 3X greater purity.
  • Heart Health: Provides 120 mg of beneficial omega-3s (DHA and EPA) per serving, which supportive research indicates may help reduce the risk of coronary heart disease.
  • Unique Antioxidant: Contains astaxanthin, an antioxidant absent in standard fish oil, which may play a role in maintaining cellular integrity.
  • Potent Formulation: Each softgel offers a minimum of 500 mg of extra strength krill oil, providing more phospholipids compared to regular 500mg krill oil.

About this item

Product details

Antarctic Krill contains omega-3 fatty acids, antioxidants and a phospholipid complex. Krill are small prawn-like creatures that comprise one of the largest biomasses in the ocean. It is one of the most abundant organisms on the planet. Krill represents a renewable and positive nutrition source.* Member’s Mark™ Extra Strength Antarctic Pure Omega-3 Krill Oil contains omega-3 fatty acids DHA and EPA. Supportive, but not conclusive research shows that consumption of EPA and DHA omega-3 fatty acids may reduce the risk of coronary heart disease.*

Krill oil contains astaxanthin, which is not seen in standard fish oil. Astaxanthin may help maintain cell integrity.*

Unlike fish oils, krill oil carries omega-3s in the form of phospholipids–liposomes or little packages that deliver the fatty acids to your body’s cells. Standard fish oils lack this phospholipid complex.*

Member's Mark™ Krill Oil is rigorously regulated from the sea to the shelf. The Marine Stewardship Council (MSC) is the world’s leading third-party sustainability certifier that monitors each step of the process. This product comes from a fishery that has been independently certified to the MSC’s standard for a well-managed and sustainable fishery.

Krill oil contains omega-3 fatty acids DHA and EPA

1Member’s Mark Extra Strength Antarctic Krill Oil contains Superba2® krill oil. Using a patented purification process, salts (including TMAO responsible for ‘fishy’ odor) are removed from Superba2® krill oil thereby minimizing the fishy aftertaste or odor commonly experienced with fish oil. This process results in a krill oil that is over 3X more pure than regular krill oil.  

2Krill oil carries omega-3s in the form of phospholipids — liposomes or little packages that deliver the fatty acids to your body’s cells.

*These statements have not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure, or prevent any disease.

†500 mg is the minimum fill of krill oil per softgel. Due to the natural variability of Member’s Mark™ Antarctic Pure Omega-3 Krill Oil, each softgel may include more than 500 mg to ensure label potency. Extra strength compared to 350 mg krill oil. §More phospholipids compared to regular 500mg krill oil.

It has helped my cholesterol levels since I’ve been taking it for several years now. I recommend it to everyone to try because it’s better than taking the regular fish oil. After just 6 months my levels were way better than when I was just taking the fish oil. These don’t give the after taste either.

Happy purchase!!!

I'm not sure if they are helping my cholesterol yet or not. My dr wanted me to start on krill oil and found Member's Mark. I was worried about the fishy taste, and I'm happy to report NO fish taste at all! Way cheaper than a brand name, too, plus easy to swallow.
