You may have seen or heard about Krill oil, but do not know much about it. It is important that you know what krill oil is and what it contains before you start using it or looking at the benefits it has to offer.
What Is Krill Oil?
As the name suggests, krill oil is an oil which is made from the small crustacean krill. Krill are similar to shrimp and found in the colder waters of the ocean. Krill is generally used as a food source for other animals such as whales, penguins, fish and seals.
Krill oil is a nutritional supplement and is harvested from the open ocean. This has raised concern as many fear this could upset the natural balance of the oceanic food chain. The commercial fishing of krill could threaten certain species which consume krill as their primary food source.
What Is In Krill Oil?
Krill oil actually contains a substance which is similar to omega-3 fatty acids which are generally found in fish. This oil is recommended for people who need to lower their triglyceride levels. Krill oil can be used as a supplement which lowers the blood lipid levels and is increasing in popularity. The difference between Krill oil and omega-3 fatty acids is that krill oil can be absorbed and carried by the cells in phospholipid form.
Krill oil is also known to contain astaxanthin which is a carotenoid antioxidant that could neutralize the effects of free radicals. This could lead to a decrease in other substances in the tissue of the body which could lead to disease.
The FDA has issued a warning which states that certain fish could have toxins such as methylmercury and this has led many people to be wary of eating fish for the omega-3 acids. However, the manufacturers of krill oil have suggested that the oil could be a safer alternative because of the lower levels of these contaminants. This has been disputed because there is still the chance that krill can contain these contaminants. A study done on krill oil has found that krill fished from Antarctica do contain high levels of certain organic pesticides.
There are many reasons why you might want to take krill oil as a supplement. Krill oil offers a good alternative to omega-3 fatty acids and could have lower levels of contaminants often found in fish.
