Fish Oil

Fatty fish, such as mackerel, trout, herring, tuna, salmon, and sardines are the primary source for fish oil. Fatty fish are sometimes referred to as “oily fish.” Nutritional supplements can be an easy and effective way to ensure daily doses of fish oil.

Health care professionals and nutritionists believe the two primary ingredients in fish oil are beneficial: docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA). Both are types of Omega-3 fatty acids. Omega-3 fatty acids are types of fat found in plant oils and certain types of marine life oils. Many health benefits have been associated with omega-3 fatty acids; however, the most prevalent and compelling are omega-3 fatty acids’ ability to help lower triglycerides (the fats related to cholesterol) and blood pressure.

It is believed that the omega-3 fatty acids are the “active ingredient” in fish oils. The human body does not produce its own omega-3 fatty acids, so, omega-3 fatty acids must be derived through diet or supplements.
