Fish oil is a dietary source of omega-3 fatty acids, which are essential for various functions in the body, including muscle activity and cell growth
. It is extracted from fish tissue, primarily from oily fish such as herring, tuna, anchovies, and mackerel
. Fish oil supplements are an alternative for those who do not consume fish regularly, as they provide omega-3 fatty acids that offer numerous health benefits
. Some of the key benefits of fish oil include:
- Heart health : Omega-3 fatty acids help reduce inflammation, lower triglyceride levels, and prevent heart disease and stroke
- Brain and eye development : Omega-3s contribute to typical brain and eye development, and may help prevent a decline in brain function
- Reduced blood clotting : Omega-3 fatty acids reduce pain and swelling, and prevent the blood from clotting easily
However, there is limited evidence to support the use of fish oil supplements for most of the claimed health benefits, such as lowering blood pressure, treating eczema, and improving diabetes
. It is essential to consult with a doctor before taking fish oil supplements, especially if you are pregnant, trying to get pregnant, nursing a baby, or taking medications like blood thinners or hormonal medications
. Fish oil supplements typically contain about 1 gram of omega-3 fatty acids, such as docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA)
. A large study showed that people who took a pure-EPA fish oil pill reduced their risk of cardiovascular disease by 25%, compared to those who took a placebo
. However, the placebo was actually mineral oil, which has since been shown to have negative cardiovascular effects, like increasing inflammation
. Therefore, it is crucial to consult with a healthcare professional before starting any fish oil supplementation.
