Fish oil is a supplement that is rich in two important omega-3 fatty acids called eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) . These omega-3 fatty acids are essential for the body and brain, and they contribute to typical brain and eye development, fight inflammation, and may help prevent heart disease and a decline in brain function. Fish oil supplements are sometimes used for heart health and mental health, but there is no strong evidence to support most of these uses.
Here are some positive and negative aspects of fish oil supplements:
Positive:
- Fish oil supplements are an excellent source of omega-3s, which is good for the heart and the brain.
- Consuming higher amounts of fish oil from foods has been linked with a lower risk of heart failure.
- Taking fish oil supplements by mouth might reduce the risk of death or hospitalization in people that already have heart failure.
- Fish oil supplements are the nonvitamin/nonmineral natural product most commonly taken by both adults and children in the United States.
Negative:
- Higher doses of fish oil can lower the bodys immune system response, which could be a problem for people whose immune system is already weak.
- Vitamins A and D can be harmful in excessive amounts, and some fish liver oil supplements, such as cod liver oil, contain these vitamins in amounts that vary from product to product.
- Fish oil supplements do not contain the same amount of fish oil as prescription products, so they cannot be used in place of prescription products.
The ingredients of fish oil supplements can vary depending on the brand. For example, one brand of fish oil supplement contains gelatin, glycerol, natural lemon oil, purified water, and natural mixed tocopherol. When choosing a fish oil supplement, its important to read the label and choose a supplement that has a high concentration of EPA and DHA and has purity and sustainability certifications.
