Krill is a tiny crustacean that resembles shrimp in appearance.

The omega 3 acids contain anti-inflammatory antioxidants that improve brain activities such as alertness, focus and acuity. Krill is found in all oceans, but commercial krill oil often comes from the krill from the Antarctic Ocean. Krill is the main source of food for whales.

The fatty acids contained in krill oil are good for enhancing metabolic activity and discouraging the unnecessary storage of fat in body through complete absorption.

Krill oil is also used for the treatment of joint-related diseases, where it helps by providing lubrication. Krill oil encourages the storage of fluid in your body, thus helping moisturize the skin, giving it a fresh appearance and preventing dryness.

The benefits of krill oil are generally greater than those of similar oils like fish oil. Where fish oil’s omega 3s needs to be converted into absorbable form, krill oil’s omega 3s are already in the directly absorbable phospholipid form [1].

It has been empirically demonstrated that krill oil is the most effective oil in terms of regulating and maintaining healthy functioning of the body. The diseases and conditions krill oil may help prevent include heart attacks, poor blood circulation, and poor function of the liver, brain, and other organs.

  • Failure of proper functioning of the liver, leading to a reduction in effective metabolic activities
  • Severe pain in the joints due to lack of lubrication
  • Retarded growth
  • Reduced hormonal function
  • Irregular heartbeats and pulses
  • Discomfort while breathing

One can see the importance of krill oil, due to its potential to prevent the above-mentioned diseases. A number of studies have been conducted in order to explore the many potential benefits of krill oil.

The findings of these research-based studies are discussed in this article. Most of the researches discussed have concluded that krill oil is more effective overall than other oils that are used as treatments or preventatives for various diseases.

Krill Oil Health Benefits

Krill Oil Side Effects

Generally , if krill oil is used for shorter period of time, i.e., a few months or less, it does not have significant side effects, but consistent use for a longer period may lead to the following side effects:

Using such medicine with krill oil will lead to an even greater risk of bleeding. The use of orlistat should also be avoid with krill oil because it reduces the absorption feature of krill oil and reduces the circulation of fat in the body.

Krill Oil vs. Fish Oil: Which is Better?

Krill Oil Vs Fish Oil

Krill Oil Vs Fish Oil

Krill oil is considered to be superior to fish oil because of its much greater potency and purity as an omega 3 supplement. Krill oil is more effective than fish oil because it provides omega 3s in phospholipid form, whereas fish oil omega 3s need to be converted into phosphor lipids to be absorbed by the human body [2].

During the conversion process, there is the possibility of losing some energy and potency. Another point of importance that gives krill oil priority over fish oil is that krill oil takes two to three hours for its decomposition, whereas fish oil takes forty-eight to seventy-two hours for decomposition and oxidation.

Furthermore, in the process of manufacturing fish oil the percentage of fat is produced high as eighty percent, the manufacturing of Krill oil produces only five percent fat. Hence, it is clear that krill oil is more effective than fish oil. Due to its high effectiveness, krill oil is more expensive than fish oil.

Krill Oil and Omega 3s

Omega 3s are a class of fatty acid that are viewed as the best for the prevention of heart diseases, including heart attacks. These acids are also vital in reducing the level of sugar in the blood. This also prevents or slow mental disorders, some types of cancers, and tissue inflammation.

This is categorized into distinct components known as ALA (alpha-linolenic acid), EPA (eicosapentaenoic acid), and DHA (docosahexaenoic acid), which are present in krill oil in the form of polyunsaturated fatty acids; due to their structural differences they are easily absorbable into the brain. Moreover, the presence of strong carotenoid antioxidants prevents the oxidation of EPA and DHA.

In addition, a study conducted by an American journal related to nutrition reveals that due the presence of these fatty acids krill oil reduces the symptoms of cardiac diseases considerably. The presence of phospholipid fat in krill oil seems to make it the best source of treatment.
