Fish oil is one of the most commonly consumed dietary supplements.
It’s rich in omega-3 fatty acids, which are very important for your health.
If you don’t eat a lot of oily fish, taking a fish oil supplement could help you get enough omega-3 fatty acids.
Here are 13 health benefits of fish oil.
Fish oil is the fat or oil that’s extracted from fish tissue.
It usually comes from oily fish, such as herring, tuna, anchovies, and mackerel. Yet it’s sometimes produced from the livers of other fish, as is the case with cod liver oil.
The World Health Organization (WHO) recommends eating 1–2 portions of fish per week. This is because the omega-3 fatty acids in fish provide many health benefits, including protection against a number of diseases.
However, if you don’t eat 1–2 servings of fish per week, fish oil supplements can help you get enough omega-3s.
Around 30% of fish oil is made up of omega-3s, while the remaining 70% is made up of other fats. What’s more, fish oil usually contains some vitamin A and D.
It’s important to note that the types of omega-3s found in fish oil have greater health benefits than the omega-3s found in some plant sources.
The main omega-3s in fish oil are eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), while the omega-3 in plant sources is mainly alpha-linolenic acid (ALA).
Although ALA is an essential fatty acid, EPA and DHA have many more health benefits
If you do not eat 1–2 portions of oily fish per week, you may want to consider taking a fish oil supplement.
EPA and DHA dosage recommendations vary depending on your age and health.
WHO recommends a daily intake of 0.2–0.5 grams (200–500 mg) of combined EPA and DHA. However, it may be necessary to increase the dosage if you are pregnant, nursing, or at risk of heart disease (116Trusted Source).
Choose a fish oil supplement that provides at least 0.3 grams (300 mg) of EPA and DHA per serving.
Omega-3s contribute to normal brain and eye development. They fight inflammation and may help prevent heart disease and a decline in brain function.
As fish oil contains a lot of omega-3s, those at risk of these disorders can benefit from taking it.
In fact, fish is as effective as fish oil — if not more so — at preventing many diseases.
That said, fish oil supplements are a good alternative if you don’t eat fish.
