Fish oil extracting involves catching the fish, processing them, and extracting the oil. After the fish are cleaned, the oil is extracted from their tissues through methods like pressing or centrifugation. It is rich in omega-3 fatty acids, which are beneficial nutrients that our bodies need for various functions.

The global fish oil market size was valued at $ 1,905.77 million in 2019 and is estimated to reach $ 2,844.12 million by 2027 with a CAGR of 5.79% from 2021 to 2027. Fish oil is derived from the tissues of fish that contain omega-3 fatty acids, such as eicosapentaenoic acids (EPA) and docosahexaenoic acids (DHA).

Fish oil supplementation has been associated with potential benefits for various health conditions including type 2 diabetes, rheumatoid arthritis, cardiovascular disease, prostate cancer, hypertension, mental health, infection, heartburn, vision loss, blood fats, and overall health. Fish oil is the main source of DHA (docosahexaenoic acid) for functional foods. It is used in various applications, including aquaculture, human consumption, and other smaller uses such as hydrogenation and industrial purposes.

 

What Are Omega-3 Fatty Acids?

Omega-3 fatty acids are a vital type of healthy fat necessary for our overall well-being. Omega – 3 fatty acids are called “essential” because our bodies cannot produce them, so we must acquire them through our diet. Omega-3 fatty acids have numerous health benefits, including supporting heart health, reducing inflammation, and promoting brain function.

Omega-3 supplementation through flaxseed oil, krill oil, fish oils, and fish consumption provides essential fatty acids, minerals, and potential benefits for cholesterol levels, triglycerides, blood levels, and overall health.
