Krill Oil: A Potent Source of Omega-3s and Antioxidants

Krill oil, derived from tiny marine crustaceans, is gaining attention for its robust health benefits, especially when compared to traditional fish oil supplements. Rich in omega-3 fatty acids, phospholipids, and the powerful antioxidant astaxanthin, krill oil offers a suite of benefits that support overall health and well-being.

What is Krill Oil?

Krill are small, shrimp-like creatures that are crucial to the marine food chain. Extracted from these crustaceans, krill oil is not only a rich source of omega-3 fatty acids but also includes phospholipids, which enhance the absorption of these fats in the body, and astaxanthin, an antioxidant that helps combat oxidative stress.

Health Benefits of Krill Oil

  1. Enhanced Bioavailability of Omega-3s: Krill oil contains omega-3 fatty acids in the form of phospholipids, which are more easily absorbed by the body compared to the triglyceride form found in fish oil (Andraka et al., 2020).

  2. Supports Brain Health: The unique composition of krill oil helps support brain health, particularly in the context of aging and high-fat diets, potentially improving cognitive functions and reducing inflammation (Andraka et al., 2023).

  3. Antioxidant Properties: Krill oil is rich in astaxanthin, a potent antioxidant that is far more effective than traditional antioxidants like vitamin E at neutralizing free radicals, thereby protecting cells from oxidative damage (Barros et al., 2014).

  4. Improves Lipid Profile: Regular consumption of krill oil can lead to improvements in lipid metabolism, reducing levels of triglycerides and potentially supporting cardiovascular health (Ramsvik et al., 2015).

  5. Supports Metabolic Health: Krill oil has been shown to influence glucose metabolism and insulin sensitivity, which could be beneficial in managing weight and metabolic health (Rossmeisl et al., 2020).


Krill oil is a highly effective supplement that not only provides the essential omega-3 fatty acids but does so in a form that is more easily utilized by the body. Its additional antioxidant properties and ability to support metabolic health make it a superior choice for those looking to maintain or improve their health.
