Krill Oil Vs. Fish Oil – Which Is Better? August 10, 2015

Popping supplements is an ’in’ thing these days. Whether you have already joined the latest craze or planning to give it a try, go through this article to get into it.

One of the most popular supplements that health conscious people stock up on is omega-3 or essential fatty acid supplements. But the question is, should you use fish or krill oil supplements?

For a long time, fish oil was the only choice for omega-3 fatty acid supplementation. From curing minor skin rashes to taking care of our cognitive health and development, the product was capable of doing almost each and everything. But then came krill oil and the industry started to market it as ‘the supplement’ to go for.

So, what is the truth? Is krill oil truly a ‘wonder supplement’ or is it a simple marketing gimmick? Do you really need to switch to it from your present fish oil supplement. Let us find out:

What Is Fish Oil?

Fish oil is the oil extracted from the oily tissues or body flesh of marine fish species like cod, halibut, tuna, herring, etc. It is rich in omega-3 fatty acids, especially the polyunsaturated fats EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid), which are known to take the utmost care of our health by keeping the cardiovascular system healthy, regulating hormonal secretions, lubricating joints, ensuring cognitive health, reducing inflammation, treating skin conditions like eczema, and so on.

What Is Krill Oil?

Krill oil is taken out from the body of the shrimp-like crustaceans called krill, which are very small and found in deep seas and oceans. It is also considered as an excellent source of omega-3 fatty acids like EPA and DHA. But the specialty of this oil is its astaxanthin component. It is a highly beneficial antioxidant that contributes to the bright red color of the creature as well as the supplements. Apart from this, krill oil comes with all those benefits that fish oil offers to us due to the presence of omega-3 fatty acids in it.
