The difference in Krill oil & Fish oil (Uses, Benefits, Side Effects)

What is the difference?

One has probably heard that it is essential to get omega-3 fatty acids (omega-3s) in the diet. Their benefits have been highly publicized. They will decrease cholesterol, promote heart health, support brain health, and decrease inflammation in the body.


The body will not make omega-3s on its own, so including them in the diet is essential both fish oil and krill oil excellent uses of these essential fatty acids. Fish oil comes from oily fish like salmon, sardines, and albacore tuna. Krill oil comes from krill, small cold-water species that same as shrimp.

Fish oil and krill oil contains two types of omega-3s DHA and EPA. Although, fish oil is a higher concentration of DHA and EPA than krill oil. The DHA and EPA in krill oil are thought to have more antioxidants and more absorption in the body.

Fish oil has an idea for decades, so it is better to study krill oil and makes a name for itself as an effective, if not perfect. The use of omega-3s keeps reading to learns more.

What are the potential benefits and uses?

According to Mayo Clinic, people in the United States have lower levels of DHA and EPA in their bodies. Then the people in Japan and other nations with lower heart disease rates. They are following a few of the other possible pros of taking fish or krill oil.


Fish oil

Some research has showing omega-3s in fish oil may

1. lower triglyceride levels

2.decrease heart attack risk

3. help maintain a normal heart rhythm

4. reduce stroke risk in people with heart problems


5. improve blood pressure

6. reduce inflammation and ease symptoms of arthritis

7. help to treat depression in many people

Even so much research on omega-3s is not ending. For example, a 2013 study involved over 1,400 people found omega-3s did not reduce heart attacks. The death in people with heart disease or heart disease risk factors. More research is need to proving fish oil will improve more conditions.


Krill oil

According to Cleveland Clinic, animal studies have shown krill oil improves DHA absorption and DHA delivery to the brain. It means less krill oil is needed than fish oil for health benefits.

But according to a 2014 commentary Trusted Source, the trial that ends krill oil is superior to fish oil. It was misleading due to its use of atypical fish oil.

What potential side effects and risks?

Both supplements generally consider safe when using in recommending doses. One will able to minimize potential side effects. Like stomach upset, by taking supplements with a meal.

One should not use fish oil or krill oil if one has a fish or shellfish allergy. Fish oil or krill oil will also increase the bleeding risk, lower blood pressure, or affect blood sugar levels.


Talk to the doctor before using if one:

having a bleeding condition or blood thinners taking.

Having low blood pressure or take medications that lower the blood pressure.

Have diabetes or hypoglycemia or taking medicines that will affect the levels of blood sugar.

Fish oil

Eat one to two meals of fatty fish weekly is also considering safe despite finding the high mercury levels, PCBs with other contaminants in fish.


Fish lowest in mercury:

Canned light tuna

Fish highest in mercury:

King mackerel

Quality fish oil supplements will not contain mercury, but they will still Cause minor side effects :

Upset stomach
Krill oil

Because krill at the bottom end of the ocean’s food chain, they don’t have time to collect high levels of mercury or other contaminants.


Krill oil supplements will cause gastrointestinal upset. However, they typically don’t cause any Belching.

How does the production of these oils affect the environment?

Seafood’s sudden move in popularity over the last couple of decades has straining some fish species and the habitat. According to Monterey Bay Aquarium Seafood Watch, “90 percent of the world’s fisheries were fully exploiting, over-exploiting, or have collapsed.”

Sustainable fishing and sustainable aquaculture, that is, fish farming, is harvesting and processing seafood. So it does not deplete an ocean species, alter its ecosystem, or negatively affect the environment.

To support sustainable fishing efforts makes sure one is getting the highest quality product possible. It makes specific fish oil, and krill oil one use is getting using sustainable methods. I am looking for products certified sustainable by the Marine Stewardship Council or the International Fish Oil Standards Program.


It would help if one also kept in mind the freshest and highest quality fish oils. They don’t taste fishy or having a strong, fishy smell.

How to use these oils

Both the oil are available in the form of capsule, chewable, and liquid. The standard dose of fish oil or krill oil for adults is 1 gram to 3 grams daily. However, these oils are best to consult the doctor for the amount that is right for one. They may advise one to use more or less.

When it comes to omega-3s, more in the diet is not better. Taking too much does not offer better results. It does increase the risk of severe side effects.

Technically, one will cook with liquid fish oil or krill oil, but it is not shared. If one wants to experiment, try adding a teaspoon to the morning smoothie or a homemade salad dressing of oil.


The bottom line

The body needs omega-3s to function, but studies mix the best way to get them and how much one should need. Eat sustainable seafood twice a week should help one to get enough, but it is no guarantee. It will be challenging to know exactly how much omega-3 is present in the fish one to eat.

As an alternative or eating fatty fish, one will enjoy flax or chia seeds because they have a high content of omega-3.

Both fish oil and krill oil are trustworthy sources of omega-3s. Krill oil seems to have a health corner over fish oil because it may be more bioavailable. But it is also more expensive and not well-studied. On the other hand, studies are mix on some of the health benefits of fish oil.

Unless one is pregnant, or until the research on both types of omega-3s is exact. Suppose you use fish oil, or krill oil comes down to personal preference.


So, it is essential information on the topic of Krill oil vs. fish oil.
