Krill are tiny crustaceans, resembling shrimp, whose population thrives in icy water. In Norway, the word “Krill” means “whale food” because it is the primary diet of whales, as well as many other marine animals. The oil from krill is extracted and put into capsules, much like fish oil, because of its health benefits. Krill oil is rich in the omega 3 fatty acids, EPA and DHA, making it a comparable substitute to fish oil. The most notable benefit of omega 3 fatty acids is its effect on heart health. EPA and DHA can reduce triglycerides, a harmful and risky fat that resides in the blood. Having too much triglycerides can increase the chance of getting heart disease. EPA and DHA have also shown to increase HDL, or good cholesterol, altogether reducing the risk of heart attack and stroke. Other benefits of omega 3 fatty acids include improving cognitive function, memory, energy, and circulation.

Compared to fish oil, krill oil may have slightly different omega 3 fatty acids that can be better absorbed. Research has shown it to be more effective than fish oil in terms of reducing bad cholesterol and increasing good cholesterol. Some also believe it to be more effective in treating symptoms of PMS and inflammation. The only drawback of krill oil is that it has not been studied well enough compared to fish oil. Although there have been many positive results, less is known about the supplement. Another thing to consider is that krill thrive in arctic sea water so it may soon be discovered that the krill population are declining due to global warming.

The daily recommended dose of krill oil is 1-3g. Studies have shown that this dose is effective in decreasing bad cholesterol and increasing good cholesterol. However, the appropriate dose can vary from person to person depending on factors like age and health conditions. People who are allergic to shellfish should not take krill oil. It can also cause a thinning of the blood, and for this reason it should be avoided when using blood thinners such as warfarin. It’s always best to consult a physician before trying a new supplement.
