Is krill oil better than fish oil? All about the new hugely popular omega-3 supplement

When it comes to omega-3 supplements, fish oil has long been a trusted ally. In recent years, its new alternative — krill oil — has emerged as a rich source of omega-3 fatty acids, packed with powerful antioxidants and a host of impressive nutrients. Derived from the microscopic, shrimp-like creatures from the icy waters of Antarctica, it boasts of a wealth of health benefits. From heart health to skin and eye health, there are many potential benefits of the new health supplement that can be absorbed more efficiently than fish oil by the body.

Krill oil is rich in two key omega-3 fatty acids — EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid). Both of these compounds are considered heart-healthy and also help fight inflammation.

Powerful antioxidant

Krill oil has a powerful antioxidant called astaxanthin which is also found in salmon and shrimp. It can support eye health and also boost krill oil’s anti-inflammatory properties. Some studies have even linked krill oil to better relief from dry eye symptoms compared to fish oil due to astaxanthin’s protective effects. Taking krill oil by mouth for about three months can improve dry eye symptoms such as redness. Krill oil can also play a crucial role in skin aging reversal and wound healing.

PMS relief

A study published in Alternative Medicine Review, suggested that krill oil can also provide relief in tackling premenstrual syndrome (PMS) symptoms more effectively than fish oil. Premenstrual syndrome includes a range of signs and symptoms like mood swings, tender breasts, food cravings, fatigue, and irritability.

Limitations of krill oil

Despite its promising perks, krill oil is not a perfect solution. A study published in Hospital Pharmacy found no significant benefits of the supplement on cardiovascular health.

There is another limitation of krill oil that could hinder its popularity and that is its price. Harvesting krill from the remote Antarctic Ocean is costly, requiring massive vessels capable of navigating one of the world’s most treacherous sea passages. As a result, krill oil supplements can cost three to four times more than fish oil.

Side effects of krill oil

Krill oil may cause digestive issues like bloating, nausea, and heartburn. Some people may be allergic to seafood or have shellfish allergies, they should avoid its use. It may also lead to bleeding risk if taken alongside blood thinners.

Eating a balanced diet rich in omega-3 foods such as fatty fish, walnuts, flaxseeds, chia seeds, and seaweed offers a more complete package of nutrients and antioxidants without the risks that come with concentrated supplements.
