Fish Oil or Krill Oil for Children?

Cooking oil has been generally used in wide area of food preparation, but a growing number of people are becoming more conscious of achieving a healthy body. While olive and coconut oil are some healthier options, people look into using alternative supplements to prevent diseases.

They say that taking a tablespoon of fish oil can make diseases avoidable, but what exactly is fish oil? Fish oil are supplements commonly used routinely by some people because of their belief that the components of fish oil can prevent cardiovascular diseases. The fact is, fish oil contains high amounts of linolenic fatty acids or Omega-3, and arachidonic acids. But preventing cardiac diseases cannot be attributed to these components according to evidences from research studies. The presumptive benefit of fish oil is only used by producers to market their products, and their claims are not even supported by clinical studies to prove the desirable effect. This led researchers to study other supplements to replace fish oil.

Krill oil is said to be the best alternative to fish oil. It is extracted from a small crustacean which is actually a food for the whales. The extracts are processed into capsules which are taken as medications. Like fish oil, krill oil also contains Omega-3, making both oils beneficial to healthy brain, heart, lungs, muscle and bones, skin, and eyes. Specifically, this is used in maintaining cholesterol levels, bone deformities, and arthritis, among others.

In terms of bioavailability, krill oil is preferred because of its phospholipid packing, making it compatible with the body because of the phospholipid component of cell membranes. In contrast, fish oil has triglyceride which requires complicated pathways for its bioavailability. The presence of a potent antioxidant astaxanthin in krill oil also makes it a better option because this prevents release of free radicals so healthy cells will be protected and maintained. The fish oil lacks this protective antioxidant. Krill oil is also a safer option for managing arthritis since a capsule already takes effect compared to 14 capsules for fish oil. Though both are lipid-containing, fish oil contains 80% fats extracted from sardines, while krill oil yields 5% and less fats. This makes krill oil more preferable because it is easily metabolized and absorbed in the body.

While research and studies are still on going, consulting a physician can help in deciding what supplement is safe to use, and what is advisable for your use. Like any other supplements, it is best to know the pros and cons of each, depending on your actual needs because many supplements available work differently for different needs of people.
