Fish Oil Supplements: Benefits, Types and Precautions
Oily and fatty fish such as salmon, mackerel, trout, tuna, sardine, and herring contain fish oil. They provide omega-3 fatty acids and are rich in vitamins A & D. Omega-3 fatty acids comprise a group of polyunsaturated fatty acids. If you don’t eat fish, fish oil supplements are your best bet to fulfil your body’s omega-3 fatty acids requirement.
The FDA recommends fish oil for daily consumption. It significantly lowers the triglyceride levels of the body and improves heart health. It also ensures proper blood circulation. In addition, it prevents heart diseases and strokes. Fish oil is also beneficial for many kidney-related problems.
The omega-3 fatty acids play multiple roles in our bodies. For example, they help in cell growth and muscle activity. However, since our bodies do not produce omega-3 fatty acids, only foods provide them. These fatty acids also prevent the clotting of blood. They can help avoid strokes.
What is Fish Oil?
Eicosapentaenoic and docosahexaenoic acids are omega-3 fatty acids found in fish. Animal products, fish, and phytoplankton contain these. Fish oil is a perfect source of omega-3, an essential fat present in the human body. As a result, it provides multiple health benefits.
Fish bodies have three types of omega-3 fatty acids. These are:
- Alpha linoleic acid (ALA)
- Docosahexaenoic acid (DHA)
- Eicosapentaenoic acid (EPA)
These acids are necessary for performing several body functions. For example, they help improve brain function, inflammatory response, and metabolic signalling. An ideal source of fish oil is fish itself. However, you can consume fish oil supplements containing EPA and DHA.
Foods rich in EPA and DHA omega-3 fatty acids include sardines, trout, salmon, albacore, shrimp, halibut, herring, clams, cot, light chunk tuna, and cod. ALA is a different kind of omega-3 acid. Vegetarian food sources such as walnuts, spinach, and flaxseed oil are good sources of ALA.

3. Eye Health
Our eyes need a healthy coating of tears. Without this lubrication, our eyes become red, scratchy and irritable. In addition, it can lead to a condition called dry eye.
According to a study published in the International Journal of Ophthalmology, omega-3 fatty acids have a definite role in dry eye syndrome. An analysis of 32,000 women found that those who consumed the most omega-3 fats from fish had a 17% lower dry eye risk than women who ate little or no seafood.
