Is Krill Oil As Good As Fish Oil?

Krill oil and fish oil both contain the omega-3 fatty acids EPA and DHA. However, there are differences in these oils that you need to know about. The primary difference is that krill oil comes from small crustaceans and not fatty fish which is where fish oil is found. The increased popularity of krill oil has led many to ask whether krill oil is as good as fish oil or not. There is actually a lot of research which has been done that can help to answer this question.

Heart Health

Fish oil is known to help reduce the risks of heart attacks due to the omega-3 acids that it contains. However, research has shown that you can get the same levels of these oils as recommended by the American Heart Association from krill oil. This is according to a study which was published in the journal Lipids in 2011. A clinical trial with 113 male and female volunteers which lasted 7 weeks found that the levels of EPA and DHA increased in groups that took krill oil and fish oil. This research suggests that krill oil provides the same level of these acids as fish oil.

Symptoms Of Arthritis

A clinical trial at the University Health Network in Toronto found that krill oil helped to reduce the pain, stiffness and inflammation linked to arthritis. During the study, levels of serum C-reactive protein were measured as this is what has been linked with chronic inflammation. The CRP levels of those taking krill oil fell by 31%, but there was a 25% rise in the levels of the group who was given a placebo.

Premenstrual Symptoms

Fish oil has been known to reduce the symptoms of PMS and pain from menstruation. However, a report published in the Alternative Medicine Review found that the reduction in these symptoms and pain was greater with krill oil. It is important to note that the krill oil used in this report was Neptune brand only. However, the report did show that krill oil was statistically more effective in the management of joint pain, emotional symptoms and breast tenderness. In terms of managing weight gain, swelling and abdominal pain, there was no difference between the 2 oils.

Many people are using krill oil instead of fish oil because they offer the same omega-3 fatty acids. Krill oil is able to help with certain symptoms more than fish oil, but you need to consider if these symptoms are what you are looking to treat.
