What is Fish Oil?
Fish oil is a dietary supplement derived from the tissues of fatty fish such as salmon, mackerel, and herring. It is a rich source of omega-3 fatty acids, which are essential nutrients that our bodies need but cannot produce on their own.
There are different types of omega-3 fatty acids found in fish oil, including eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). These fatty acids have been studied extensively for their potential health benefits.
Fish Oil vs. Omega-3: What’s the Difference?
While fish oil and omega-3 are often used interchangeably, they are not the same thing. Omega-3 refers to a group of fatty acids that are beneficial for human health, while fish oil is a specific source of these fatty acids.
One key difference between fish oil and omega-3 is their composition. Fish oil contains a mixture of different fatty acids, including omega-3, omega-6, and omega-9. On the other hand, omega-3 supplements typically contain only the beneficial omega-3 fatty acids, such as EPA and DHA.
Another difference is how they are absorbed by the body. Omega-3 supplements are often more easily absorbed than fish oil, which may require digestion before the body can fully utilize the fatty acids. This means that omega-3 supplements may be more effective at delivering the desired health benefits.
| Fish Oil | Omega-3 Supplements |
|---|---|
| Contains a mixture of different fatty acids, including omega-3, omega-6, and omega-9 | Contains only the beneficial omega-3 fatty acids |
