What Is Krill Oil and Why Should You Care?

First off, let's look at what a “krill” is. These are very small crustaceans that look a lot like shrimps. They are in fact the most abundant crustacean in the oceans. Krill are mostly fished in the icy cold waters of the Antarctic shore. You will often see products advertised as “Antarctic pure krill oil.” Some of the bigger sea animals like seals, penguins and baleen whales like to feed on krill.

The manufacturers of dietary supplements now collect this source of omega-3 to offer a new choice in fish oil supplements. Quality capsules will contain particularly high levels of EPA and DHA. These are the fatty acids your body needs to function properly. Aside from the omega-3 fatty acids, these tiny shellfish also contain two antioxidants, one called phosphatidylcholine and the other astaxanthin. These anti-oxidants claim to have various health benefits too, which is a bonus.

The Main Benefits of Krill Oil

We buy krill oil supplements mostly for their omega-3 content.  Your body needs omega-3 to perform a whole range of bodily functions, making it one of the most vital nutrients to supplement with today. The reason why a lot of people need omega-3 in supplement form is because it's one of the nutrients that's lacking in the typical western diet. Krill oil supplements can benefit human health in the following areas:

  • Alzheimer's disease and dementia
  • Asthma
  • Baby development
  • Curbs stiffness and joint pain (rheumatoid arthritis)
  • Help to reduce the symptoms of depression
  • Lowers blood fat (triglycerides)

As you can see, this is an important supplement, especially if your diet is typically western. Many of us fall far short on omega-3 and consume too much omega-6. This imbalance is harmful to health and can lead to all kinds of complications in the mid to long term.
