USP Verified

Antarctic krill are tiny shrimp-like creatures that thrive in the ocean’s pristine and extreme conditions. Nutrition-wise, they are naturally high in omega-3 fatty acids (EPA and DHA) and antioxidants. The typical North American diet is deficient in omega-3 fatty acids, so supplements provide the simplest, most consistent source of these essential fatty acids.

Krill oil is unique because it contains phospholipid-bound omega-3s making it easier to absorb and more bioavailable than triglyceride-bound omega-3s found in fish oil.1†‡ Phospholipids are a class of fats that are the essential building blocks of all cell membranes – and they have a simpler digestive process than other forms of fatty acids. Because of their superior absorption, you only need one small softgel per day to get the same benefits as the regular fish oil dosage.

Krill oil is recognized for its deep red-orange pigment from the naturally occurring carotenoid called astaxanthin.

Superior absorption‡

The omega-3s in krill oil are bound to phospholipids, making them much more easily absorbed into the body.†1 The omega-3s in fish oil are bound to triglycerides, which need to be broken down and digested in the small intestine.

Naturally occurring astaxanthin

Krill oil contains astaxanthin, a naturally occurring carotenoid that offers overall protection against oxidative damage from free radicals.†


One pill per day

Because of its superior absorption compared to fish oil, the suggested dose for Kirkland Signature Krill Oil is only one (1) softgel daily.

Small, easy-to-swallow softgels

Compared to omega-3 from fish oil, Kirkland Signature Krill Oil softgels are small and easy to swallow.

No fishy odor or aftertaste

Krill oil does not have the fishy odor or aftertaste that is common in fish oil.

Pure Antarctic krill

Kirkland Signature Krill Oil is made with 100% pure Antarctic krill oil, sustainably sourced from Antarctic waters.
