Krill Oil vs Fish Oil: Which One Is Better for Your Health?

You might not know it, but krill and fish oil are two of the most popular oils on the market today. Both are rich in omega-3 fatty acids, which have numerous benefits for your health. Research indicates that these nutrients can reduce your risk of cardiovascular disease and other chronic illnesses. That being said, there are some important differences between krill oil and fish oil that you should understand before making a purchase. Let’s take a closer look at what sets these two oils apart and how they can benefit your health.

What is Krill Oil?

Krill oil is a type of marine oil that is extracted from krill. These are tiny crustaceans found in oceans around the world. Krill oil is sometimes referred to as “swimming fish oil” due to the similarity between the omega-3 fatty acids in krill and those in fish oil. Krill oil is often promoted as a source of antioxidants since it contains large amounts of vitamin E.

This oil is also a good source of vitamin A, vitamin D and selenium. Like fish oil, krill oil is rich in omega-3 fatty acids. These acids can help to reduce your risk of cardiovascular disease and reduce blood pressure.

What is Fish Oil?

Fish oil is a type of oil that is extracted from fatty fish such as salmon, mackerel, herring, sardines and anchovies. A single tablespoon of fish oil contains more omega-3 fatty acids than a pound of salmon! Fish oils are rich in two types of omega-3 fatty acids: eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA).

These fatty acids can have numerous beneficial effects on your health. For example, regular fish oil consumption has been linked to a reduced risk of cardiovascular disease and reduced blood pressure. Fish oils also contain vitamin D, vitamin E and a compound called coenzyme Q10, which may help to lower your risk of certain types of cancer.

Benefits of Krill and Fish Oils

As we mentioned, both krill oil and fish oil are rich in omega-3 fatty acids. These fatty acids can have numerous health benefits. For example, they can reduce your risk of cardiovascular disease, they can lower your blood pressure and they can also reduce your risk of certain types of cancer. In addition to omega-3 fatty acids, krill oil also contains large amounts of vitamin E. This antioxidant has been linked to a reduced risk of certain types of disease and an increased lifespan. Fish oil also contains vitamin E, as well as vitamin D and coenzyme Q10, which may also have beneficial effects on your health.

Side by Side Comparison

Now that we’ve explored the benefits of krill oil and fish oil, let’s take a look at some of the key differences between the two oils.

Source: Krill oil is derived from crustaceans, while fish oil is derived from fish.

Omega-3 fatty acids: Both oils are rich in these beneficial fatty acids. Krill oil contains alpha-linolenic acid (ALA), which your body has to convert into EPA and DHA. However, fish oil contains EPA and DHA in their fully-formed form, which can be useful for those who don’t fully convert ALA.

Vitamin E: Krill oil is much higher in vitamin E than fish oil. Fish oil contains only around half of what krill oil contains. Vitamin E has been linked to a reduced risk of certain types of disease, including cardiovascular disease and certain types of cancer.

Vitamin D: Both krill oil and fish oil contain vitamin D. However, krill oil is much higher in this nutrient than fish oil.

Coenzyme Q10: This compound is present in both oils, but at much higher amounts in krill oil.

Risks: Both oils have a risk of toxicity, but krill oil is much more likely to cause a negative reaction than fish oil.

Which Is Better: Krill Oil or Fish Oil?

As we’ve seen, both oils have their unique benefits. However, krill oil may be slightly better than fish oil. Krill oil is higher in vitamin E and vitamin D than fish oil. It also contains less EPA and DHA than fish oil. Since these are the most beneficial components of these two oils, this could be a reason to choose krill oil over fish oil.

One thing to keep in mind is that fish oil may be better for pregnant or breastfeeding women since krill oil contains vitamin E, which may be harmful to fetuses. Since fish oil is a better source of EPA and DHA, it’s also a better choice for children, athletes and older people, who may not fully convert ALA.

Summary

Krill oil and fish oil are two types of marine oil that are rich in omega-3 fatty acids. These fatty acids can have many health benefits and have been linked to a reduced risk of cardiovascular disease and other chronic diseases. While similar in many ways, krill oil and fish oil are also slightly different. These differences include source, omega-3 content, vitamin E content, vitamin D content and coenzyme Q10 content. Overall, krill oil may be slightly better than fish oil. These oils can have many health benefits, including reduced risk of cardiovascular disease and reduced blood pressure. They may be especially beneficial for pregnant or breastfeeding women and younger people, who may not fully convert ALA.
