Krill Oil

Krill oil is omega-3 in phospholipid form derived from Antarctic krill. It has better bioavailability than regular fish oil and also contains astaxanthin.

What is Krill Oil?

Krill oil is a dietary supplement extracted from Antarctic krill, a small crustacean species rich in omega-3 fatty acids. These fatty acids are in phospholipid form, which gives krill oil better bioavailability than traditional fish oil. In addition to omega-3, krill oil also contains astaxanthin, a powerful antioxidant that gives the oil its characteristic red colour. Krill oil has become increasingly popular as a way to support general health and wellbeing.

How does it work in the body?

Omega-3 fatty acids are important for many bodily functions, including brain health, inflammation, and the cardiovascular system. When krill oil is absorbed in the body, the phospholipids are quickly transported to the cells, making the omega-3 fatty acids easier for the body to utilise. The astaxanthin in krill oil also helps protect cells from oxidative stress, which can have positive effects on health.

Scientific benefits

Several studies have investigated the potential health benefits of krill oil. Research has shown that krill oil may help to:

  • Reduce inflammation in the body, which can be beneficial for people with joint issues such as arthritis.
  • Improve lipid profiles, meaning it can lower triglyceride levels and increase HDL cholesterol (the "good" cholesterol).
  • Support brain function and improve cognitive abilities in older individuals.
  • Have a positive effect on mood and reduce symptoms of depression.

Research published in the journal "Lipids" demonstrated that krill oil can effectively lower triglyceride levels in overweight individuals. Another study in the "Journal of Nutritional Biochemistry" showed that krill oil can improve memory function in older adults.

Dosage and recommendations

A typical dose of krill oil ranges from 500 mg to 3000 mg per day, depending on individual needs and health conditions. It is recommended to follow the instructions on the product label or consult a doctor before starting krill oil, especially if you have underlying health issues or are taking other medications.

Best sources and forms

Krill oil is available in various forms, including capsules and liquid extracts. When choosing krill oil, it is important to ensure the product is of high quality and free from contaminants. Look for products certified by third-party organisations to guarantee their quality and purity.

Side effects and warnings

Krill oil is generally considered safe for most people when taken at recommended doses. Common side effects may include:

  • Mild gastrointestinal discomfort
  • Bloating
  • Red rashes

People allergic to shellfish should avoid krill oil, and it is always best to consult a doctor before starting any new supplement.

Frequently asked questions

Is krill oil better than fish oil?

Krill oil has higher bioavailability than fish oil, meaning the body can absorb and use the omega-3 fatty acids more efficiently. Additionally, krill oil contains astaxanthin, an antioxidant not found in fish oil.

Can I take krill oil if I am pregnant or breastfeeding?

There is limited research on the safety of krill oil during pregnancy and breastfeeding. It is best to consult a doctor before taking krill oil in these cases.

How long does it take before I notice the effects of krill oil?

The effects of krill oil can vary from person to person. Some may notice improvements within a few weeks, while others may need to take it for several months to see noticeable results.

Can krill oil interact with other medications?

Yes, krill oil can interact with blood-thinning medications and other drugs. It is important to discuss with a doctor if you are taking other medications before starting krill oil.
