Krill Versus Fish Oil: Our Take

We have received numerous inquiries recently regarding our feelings about krill oil.

Dr. Mehmet Oz recently said on his show that krill oil may be even better than fish oil for fighting diseases. During the segment, he said krill may be a "faster and stronger" omega-3 source than fish oil. Dr. Oz used an infographic to show krill oil has been shown to be more bioavailable than fish oil. He referenced a study that showed krill oil has more omega-3s than a similar dose of fish oil. He also noted that krill oil contains astaxanthin, which he said helps krill oil from becoming oxidized.

The problem with the Dr. Oz effect is that he has purported as many failures as successes (i.e. acai, hoodia, among others). This is not to say that krill oil is all hype. It is not. However, we would not put away your fish oil any time soon.

Krill are little shrimp, so are not recommended for those with a shellfish allergy.

Krill is much more expensive than fish oil.

Provides Much Less EPA/DHA
Krill oil does not provide more EPA DHA than fish oil. For example, a popular krill product claims 2 capsules provides 90 mg EPA and 50 mg DHA. 2 softgels of your average fish oil provides 600 mg EPA and 400 mg, which is a suggested daily maintenance dose.

Contains Omega-6
Krill naturally contains omega 6 fatty acids (20 mg in product we researched). These are considered inflammatory fatty acids that compete with omega 3's.

High Phospholipids Not for Everyone
Krill contains a lot of phospholipids (mostly phosphatidylcholine, which can be beneficial if you need it, but not everyone does).

There are huge questions about krill's sustainability if it becomes more popular. Krill provides food to many large mammals (including whales) and is not easily replaced.
Calamari oil is much more sustainable and provides about the same amount of EPA/DHA.

The most beneficial aspect of krill oil is astaxanthin, which is an antioxidant that has gotten much attention recently (from none other than Dr. Oz).

In conclusion, we are not dissuading you from taking krill oil. However, for the aforementioned reasons, we still support supplementing with high quality fish oil.
