Fish Oil: Potential Health Benefits and Risks

Fish Oil: Potential Health Benefits and Risks

Fish oil, one of the most popular dietary supplements, has received attention for its potential health advantages, ranking third in the U.S. market after vitamin D and magnesium.

However, new research has called into question some of its stated benefits, notably in terms of cardiovascular health.

Despite this, fish oil continues to be of interest due to its possible impact on a variety of health outcomes.

What is fish oil? Fish oil is derived from fatty fish such as salmon, tuna, and sardines and contains lipids high in omega-3 fatty acids. These fats are extracted, refined, and separated to create supplements in variety of formats, including liquid, capsules, gummies, and tinctures.

Health Benefits:

  • Anti-inflammatory Properties: Fish oil is well-known for its ability to reduce inflammation, potentially lowering the risk of chronic diseases like autoimmune disorders, arthritis, and cardiovascular disease.

  • Pregnancy and Infant Health: Omega-3 fatty acids are necessary for fetal development during pregnancy, since they promote visual and neurological growth in utero and reduce the incidence of perinatal depression.

  • Brain Health: Omega-3 fatty acids may improve memory and cognitive function in adults, especially in older adults and those who have limited access to omega-3-rich meals.

  • Mental Health: Research indicates that fish oil supplementation may improve symptoms of anxiety and depression, but further research is needed to demonstrate its efficacy as a routine treatment.

  • Eye Health: Fish oil supplements can improve the health of the eyes by increasing tear production and lowering the risk of dry eye syndrome.

Before beginning fish oil supplementation, it's important to check with a healthcare provider to assess potential risks and benefits. To ensure safety and efficacy, follow suggested dosage guidelines and keep an eye out for any interactions with other medications or allergies.


Despite recent scrutiny of its cardiovascular benefits fish oil remains a topic of study due to its potential impact on a variety of health outcomes. Individuals can improve their general health by including fish oil supplements into their daily routine and speaking with healthcare specialists.
