Even though cholesterol has a bad reputation, it has a crucial job to the human health. Cholesterol has many vital functions in the body, and about 20% comes from the food we consume, while the remaining percentage is manufactured by the liver.

Cholesterol makes vitamin D, estrogen for women, testosterone for men, Myelin sheath which is a protective cover for the nerves and bile which helps absorb certain vitamins and fatty acids.

However, when the total cholesterol levels and LDL cholesterol are elevated, it brings about the risk of strokes and heart diseases. To those with elevated levels of cholesterol, doctors frequently prescribe drugs like statin drugs, which is simvastatin and atorvastatin which are cholesterol-lowering drugs. However, krill oil is a better alternative.

CRP increases the risk of stroke and heart disease because it is an inflammation protein. When you have excess inflammation, you are also more prone to many another disease. Krill oil reduces CPR levels and inflammation.

Excess weight has been a worldwide health concern for so many years. Obesity gravely increases the risk of medical issues like heart disease, diabetes, and stroke.

Krill Oil vs. Fish Oil

When it comes to fish oil, it doesn’t really matter if you get them from cod, salmon, sardines or mackerel, they are all high in a good concentration of DHA and EPA. As long as it’s not farm-raised, but wild-caught, fish oil has a significant concentration of essential fatty acids.

However, compared to fish oil, krill oil has the upper hand because it is the most bioavailable, most potent of oil that you can purchase for restoring balance to your DHA and EPA levels. Unlike fish oil, the essential fatty acids in krill oil are not in triglycerides form.

Also compared to fish oil, krill oil has more absorbable phospholipid forms of DHA and EPA, which is why it decreases the cholesterol synthesis in your body and provides better levels of nutrients.

Off-the-shelf fish oil, 25% of the products are damaged from oxidation. Krill oil, on the other hand, can be stored at high temperatures and stay for longer which is crucial.

Another leverage krill oil has over fish oil is that it has one of the efficient natural sources of astaxanthin which it has a very healthy and very potent carotenoid antioxidant. Astaxanthin also helps your body make the best use of DHA and EPA and protect the fatty acids from ever being degraded.
