What Is Krill Oil?

Krill oil is extracted from tiny sea crustaceans called Antarctic krill and is full of both EPA and DHA. This oil is able to be absorbed better than fish oil since it binds to phospholipids as opposed to triglycerides. The benefits of krill oil, although similar to fish oil, do offer some differences that will make you think twice about which omega-3 supplement you buy.

Krill oil can enhance bioavailability because they attach to phospholipids which make omega-3’s easier to absorb allowing for better digestion. In terms of cardiovascular health, krill oil can lower bad cholesterol and triglyceride levels, while increasing your good cholesterol levels (1) to keep your heart health stable and free from serious harm.

The red color of krill oil comes from an antioxidant called astaxanthin which can support your immune system and work to reduce inflammation (2) to improve your workouts and recovery time. The presence of astaxanthin and its valuable properties makes krill oil a popular option.

Krill Oil Vs. Fish Oil

Many of us have heard of fish oil and often associate omega-3’s with strictly fish oil. But with krill oil entering the mix, we now have a worthy opponent to battle alongside fish oil. When it comes down to it, fish oil binds to triglycerides in efforts to then be absorbed by the body. What krill oil does is actually bind to phospholipids, making it much easier and simpler for your intestines absorb this (6). Krill oil also contains astaxanthin which is a potent carotenoid providing for many benefits to your body. So, while fish oil can still offer great benefits, krill oil is definitely something to consider as if may be more effective for your intended goals.

You deserve to have the best products in your routine and working with quality products and companies is an easy way to make that happen. We then look at the ingredients, in terms of how much krill oil is included and any other added ingredients to the supplement. Finally, we look at price.
