Reducing triglyceride levels: Triglycerides are a type of fat that circulates in the blood. The body makes triglycerides and gets them from food. Doctors may prescribe omega-3s to lower triglyceride levels, as high amounts in the blood may lead to heart disease. However, a 2018 review found no link between omega-3 supplements and heart disease.

Reducing the risk of postpartum depression: A 2018 review found that taking EPA supplements during pregnancy and postpartum helped reduce some symptoms of postpartum depression. DHA supplements also reduced the risk of developing postpartum depression. However, more research is needed to support these claims.

How much fish oil to take
According to the National Institute of Health (NIH), a person’s recommended daily intake of omega-3s will change depending on their age, sex, and whether they are pregnant or breastfeeding. However, there are no official recommendations for daily EPA and DHA amounts.
National Institute of Health (NIH)
The American Heart Association, Food and Drug Administration (FDA), and Dietary Guidelines for Americans 2020–2025 offer their omega-3 recommendations in fish intake rather than grams of EPA and DHA.

Doctors may recommend higher amounts — potentially 1,000 mg and above per day — to people with high triglycerides or a history of heart disease.
recommend
high triglycerides
People ages 14 years and over who are pregnant should aim for 1.4 g (grams) of omega-3s per day, and those who are breastfeeding should consume 1.3 g per day.
The NIH does not report an established upper intake level for omega-3s. At very high doses, DHA and EPA may affect immune function by suppressing inflammatory responses. They may also increase bleeding time. According to the FDA, it is safe to take supplements containing no more than 5 g per day of EPA and DHA.

How is the oil sourced?
Omega-3s occur naturally in some foods, and manufacturers often add them to fortified foods. When it comes to sourcing fish oil, the exact process differs from company to company. Typically, a manufacturer will process whole fish, trimmings, and other fish byproducts for their oil.
Are there any risks or side effects?
Fish oil supplements are typically safe for people to consume when used as recommended. However, although the supplements are mild, some people may experience side effects such as nausea and diarrhea. Additionally, people may also experience a fishy aftertaste.
side effects
People with an allergy to fish or shellfish should not take fish oil supplements.
Certain medications may interact with omega-3 supplements. These include blood thinners, such as aspirin and rivaroxaban (Xarelto).
