Enhanced, Exclusive Sam's Club Formula Greater purity from a patented concentration process. With increased phospholipids, astaxanthin and 5 mg more total omega-3s than National Brand 500 mg krill oil. Member's Mark Extra Strength 100% Pure Omega-3 Krill Oil is an exclusive Sam's Club formula. With 200 mg Phospholipids 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. Heart Health Member's Mark Extra Strength 100% 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.

Antioxidant Protection Krill oil contains astaxanthin, which is not seen in standard fish oil. Astaxanthin may help maintain cell integrity. 3x More Pure - Superba2 Member's Mark Extra Strength 100% Pure Omega-3 Krill Oil is 3x more pure than regular krill oil.

Salts and other impurities are removed via a patented process to provide the purest krill oil available.

No fishy aftertaste or odor Through the patented purification process, odor-causing components are eliminated from the Superba2 krill oil, thereby minimizing any of the fishy aftertaste or odor that can be experienced with fish oil.

MSC-Certified Sustainable Our krill oil is rigorously regulated from the sea all the way to our shelves. Marine Stewardship Council (MSC) is the world's leading third party sustainability certifier that monitors each step of the process.

Product of Antarctic Ocean, processed and bottled in the United States
