Omega-3 fatty acids play a vital role in the neural development of the baby, especially the development of the brain and eyes (1). Therefore, it is important to include foods rich in omega-3s in your pregnancy diet. Among the different foods you can consider, fish oil perhaps has the highest concentrations of this structured fat. But is fish oil a good option for you?
Is It Safe To Take Fish Oil During Pregnancy?
Yes and no, since it depends on the type of fish oil you consume. There are two types of fish oil (2).
- Fish oil taken from the body (i.e., flesh) of the fish is safe.
- Oil taken from the liver of fish, i.e., cod liver oil, is not safe during pregnancy as it contains high levels of retinol (vitamin A), which puts your baby at risk of birth defects.
When used the right way, fish oil can be beneficial during your pregnancy.

Fish oil offers benefits derived from two types of omega-3 fatty acids: EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid).
- Balances production of prostaglandins: Omega-3s found in fish oil manage the production of prostaglandins that regulate blood pressure, blood clotting, inflammation and allergic responses, gastrointestinal and kidney functioning, hormone production and nerve transmission (3).

Frequently Asked Questions
1. How long should you take fish oil while pregnant?
There is no medical recommendation for taking fish oil during pregnancy. If you include oily fish in your diet, there is no need for additional supplementation. You may have up to two portions of oily fish every week, to get the required dose of omega-3 fatty acids. Fish oil supplements also contain other nutrients such as iron, calcium, and Vitamins A, B2, C, and D.
2. Are fish oil and omega-3s the same thing?
No, Fish oil and omega-3s are not the same. Fish oil is an excellent source of omega-3 fatty acids, which are also found in flaxseeds, dark leafy greens, and walnuts.
Since the body cannot synthesize fatty acids, we have to depend on foods rich in omega-3s, of which fish is an excellent source. If your doctor gives you the go-ahead, you can safely consume fish oil supplements for a healthier pregnancy.
