What Is Krill Oil ? Comparing Krill Oil To Fish Oil

You might have heard or seen advertising touting krill oil, a supplement made from tiny sea animals that serve as a food source for many types of marine life. But will it work for you?

A great deal of scientific study has been devoted to answering this question. There is a substantial amount of evidence indicating there are several krill oil benefits. But first…


Krill live mainly in the Southern Ocean, near Antarctica. A krill looks a bit like a shrimp, and it feeds on microscopic marine algae known as phytoplankton. Krill oil has become a popular supplement because it is high in healthy fat, known as omega-3 fatty acids, which have been associated with many different health benefits.


So, should you stay with fish oil, or move on to krill oil as your supplement of choice? Both of them contain omega-3s, which, as you’ve already seen, provide many health benefits.

In addition, krill oil softgels are typically smaller than fish oil, so they’re easier to take. From a sustainability standpoint, krill not only reproduce quickly, they are also found in abundant numbers in the ocean.

Krill oil also contains astaxanthin, which you now know may help your skin, and offer other potential health benefits. For example, it helps to fight some of the damage that oxidation can do to your body.

Oxidation occurs naturally. In fact, it plays a very important role in helping you get the energy you need to be able to function properly.



But oxidation also has a bad side. For example, whenever you see a rusted piece of metal, that’s oxidation at work. Inside your body, oxidation can cause some issues. The creation of free radicals is one of the worst. These molecules are missing an electron, and they search your body to find a replacement. Free radicals really don’t care where they get it. They’ll often take electrons from the cells that make up your tissue and muscles. When they steal electrons from those cells, it can result in severe bodily damage.

Astaxanthin is an antioxidant. This means it will freely give up an electron to a free radical, sparing your body’s tissue and muscles from harm. In fact, research indicates that astaxanthin does a much better job of fighting free radicals than vitamin C or vitamin E, two of the most effective antioxidants around.


krill oil contains ingredients that have been shown to help boost your health in many different ways. These benefits include improved cardiovascular health, stronger bones, and healthier skin. But, just like any supplement, make sure you speak to your doctor first before you add krill oil to your daily health regimen.
