Krill oil is made from a tiny shrimp-like animal called the krill. This oil is rich in omega-3 fatty acids, which are essential for many bodily functions. Krill oil supplementation can have many health benefits, especially if you are following a generally healthy lifestyle.

Omega-3 fatty acids perform several essential functions in the human body. They help with fighting inflammation in your joints and blood vessels, and they can help to lower triglyceride levels, and even fight high blood pressure. In addition, recent research suggests that they can help to alleviate the symptoms of rheumatoid arthritis and depression, and also reduce your risk of developing cardiovascular problems.

One interesting benefit of krill oil is that it may help to reduce symptoms of PMS in women who typically suffer from painful periods. To date, there is only one small scale study which suggests this, and the study has been criticised for having a small sample size, but this health benefit is worth investigating if you are someone who suffers from heavy PMS.

Other noteworthy benefits associated with krill oil include improved cognitive function, and protection [may reduce risk] against various skin conditions, including psoriasis and skin cancer. Again, more research on those claims is needed. Research on the cancer-preventing properties of astaxanthin in rats has proven promising so far, but evidence for humans is lacking.

In addition to omega-3 fatty acids, krill oil also contains astaxanthin, a powerful antioxidant which helps to protect your body from free radicals. Astaxanthin is considered to be a particularly potent type of antioxidant because it is thought to be able to fight more than one free radical at a time, helping to fight cellular damage and slow the effects of ageing.

Why Krill Oil?

There are many foods that contain omega-3 fatty acids, but krill oil is one of the best sources. It is difficult for the body to absorb omega-3 fatty acids from fish oil and plant based sources. Krill oil is special in that the omega-3 fatty acids are stored in a phospholipid form, which humans can more easily digest. This increased bioavailability is a huge benefit.

Most people can take krill oil safely; however there are some people for whom it is contraindicated. If you are allergic to shellfish, or you are taking certain prescription medications, including blood thinners, then you should not take krill oil supplements. Speak to your health professional before starting any supplementation regime.

Overall, krill oil is a supplement worth investigating.
