High in  omega-3 fatty acids and antioxidants, the potential benefits of krill oil are quite impressive.

• Antarctic krill is one of the most abundant animal species on Earth, and scientists estimate that there are almost 500 million tons in the Southern Ocean. Female krill can lay up to 10,000 eggs at a time and can lay eggs several times each season.


• They are also incredibly tough. During winter, when food is scarce, they manage to find other sources of food, such as algae that grow below the surface of the ice, on the bottom of the ocean, or even on other animals. In tough times, krill can survive up to 200 days without food.

• However, krill is also an essential part of our ecological community. Because many other species depend on krill for survival, organizations like the Convention for the Conservation of Antarctic Marine Living Resources help maintain the delicate balance of the ocean ecosystem by setting krill catch limits to prevent overfishing.

What is Krill Oil?

Krill oil is a supplement extracted from a species of Antarctic krill, which is a small shrimp-like crustacean found in the Southern Ocean. Located at the bottom of the food chain, krill mainly feed on phytoplankton or microscopic marine algae.

Krill oil contains a highly concentrated amount of omega-3 fatty acids, which have been linked to an extensive list of health benefits, from reducing inflammation to lowering the risk of chronic diseases.
