Comparing Krill Oil and Fish Oil

Krill oil and fish oil are somewhat similar as you can imagine, and they share many of the same health benefits. Still, they do have their differences, and each substance can offer unique advantages when made a special part of your diet. Here is a brief look at the key differences between krill oil and fish oil.

Fish Oil

Source

Fish oil is extracted from oily, cold-water fish such as albacore tuna, cod, halibut, herring, mackerel, salmon, and sardines.

Nutritional content

Fish oil and krill oil are both rich in DHA and EPA omega-3 fatty acids. Krill oil seems to contain other essential nutrients that fish oil does not; however, fish oil remains a reliable source of omega-3 fatty acids.

Health benefits

Because fish oil is rich in essential fatty acids, it offers a wide variety of health benefits. There is a great deal of research to suggest that taking fish oil can help treat symptoms of Alzheimer's disease, arthritis, cancer, and cardiovascular disease. Fish oil has also been linked to weight loss, improved immunity, and reduced inflammation throughout the body. It may even help reduce symptoms of mental conditions such as anxiety, depression, bipolar disorder, and general stress.

Krill Oil

Krill oil is extracted from krill, which are tiny shrimp-like crustaceans that thrive in saltwater in colder climates. They feed on plankton floating on the ocean’s surface.

Nutritional content

Again, krill oil and fish oil are both rich in DHA and EPA omega-3 fatty acids. Krill oil, however, contains a higher concentration of EPA. It also contains the antioxidant astaxanthin, which is what gives krill oil and crustaceans their characteristic red color. In addition, it is rich in vitamins A, E, and D.

Health benefits

As you can imagine, the health benefits that krill oil has to offer are much like those that fish oil has to offer. Krill oil has been linked to improved symptoms of a number of health conditions, including high blood pressure, high cholesterol, heart disease, stroke, depression, and even cancer. Because of its unique composition, the fatty acids in krill oil actually absorb more readily than those in fish oil. That means that you can take a lower dosage of krill oil and still reap the same benefits that you would with fish oil. Like fish oil, krill oil also has anti-inflammatory properties.
