Omega-3 fatty acids are well-known to aid in minimizing heart disease risk and other conditions such asinflammation, different types of cancers and stroke. Several studies prove this to be true. However, some people are unaware of what types of Omega-3 should be absorbed by the body. There are three components of these acids and they are known as; EPA, DHA and ALA. Marine sources are where you can get DHA and EPA.
On the other hand, plant-based foods are the best sources for ALA. EPA and DHA that come from marine sources can easily get inside the body than ALA. Some of the most popular marine sources for Omega-3 fatty acids are fishes like tuna and salmon. These acids are then placed in supplements and sold on the market.
The problem regarding fish is that they may contain toxins that can be passed on to those who are taking these supplements. Because of this, more and more people now prefer Omega-3 fatty acids coming from krill oil which is a shrimp-like organism over the one that comes from fish. The oil that comes from fish and krill are almost the same because both of them have DHA and EPA in them.
However, what makes them distinct from one another is that the one that comes from krill is connected to phospholipids. Due to this difference in structure, the oil coming from krill is better absorbed by the body and the brain. Aside from that, the Astaxanthin in EPA and DHA coming from krill is the one that stops its oxidation. If you want a new and better source for omega-3 fatty acids, choose krill oil.
