Krill oil

What is Krill oil?

Krill oil is a marine source of omega-3 fatty acids extracted from small crustaceans called krill. These small organisms, primarily found in the Antarctic seas, are a rich source of both eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) in a unique phospholipid form. This form of omega-3 allows the fatty acids to be more easily absorbed by the body compared to other sources, such as fish oil. In addition to omega-3, krill oil also contains astaxanthin, a powerful antioxidant that gives the oil its characteristic red colour and may help protect cells from oxidative stress.

How does it work in the body?

Krill oil works by delivering essential omega-3 fatty acids EPA and DHA, which are crucial for several bodily functions. When krill oil is consumed, the phospholipids are easily absorbed in the intestines and transported to the cells, where they can help support brain function, heart health, and overall inflammation levels in the body. Omega-3 fatty acids are known for their role in producing eicosanoids, which are signalling molecules that regulate inflammation and other important processes in the body.

Scientific benefits

Several studies have investigated the potential health benefits of krill oil. According to a study published in the Journal of Nutritional Biochemistry, participants who took krill oil showed a significant reduction in triglycerides and LDL cholesterol, which are important factors for heart health. Additionally, research has shown that krill oil may help reduce inflammation and support joint health, which is particularly beneficial for individuals with joint issues. Another study in Marine Drugs reported that the astaxanthin in krill oil may have neuroprotective effects and protect against neurodegenerative diseases.

Dosage and recommendations

The recommended dose of krill oil can vary depending on individual needs and health conditions. Generally, a dose between 500 mg and 3000 mg per day is recommended. It is important to always follow the manufacturer’s instructions and consult a doctor before starting a new supplement, especially if you have underlying health issues or are taking other medications.

Best sources and forms

Krill oil is commonly available in capsule or liquid oil form. When choosing krill oil, it is important to select high-quality products certified by third parties to ensure purity and potent content. A well-known certification is Friend of the Sea, which guarantees that the krill oil has been harvested sustainably. It may also be beneficial to choose krill oil containing astaxanthin for additional antioxidant benefits.

Side effects and warnings

Krill oil is generally considered safe for most people when used at recommended doses. However, some may experience mild side effects such as stomach discomfort, nausea, or diarrhoea. Since krill is a shellfish, individuals with shellfish allergies should avoid using krill oil. It is also important to consult a doctor before starting krill oil, especially if you are pregnant, breastfeeding, or taking blood-thinning medications.
