There are two different sources of DHA, fish oil DHA and algal oil DHA. This article introduces you to the DNA content and health benefits of fish oil.
What is fish oil？
In a broad sense, fish oil is the fat of fish, including cod liver oil, but the common fish oil refers to deep-sea fish oil rich in omega-3 series of unsaturated fatty acids. Its main components are DHA and EPA, which can regulate blood lipids (triglycerides) and protect cardiovascular and cerebrovascular.
Fish oil is a fatty acid derived from fish and seafood, rich in omega 3 fatty acids (n-3). But fish oil is different from omega 3 fatty acids, because the content of omega 3 fatty acids in ordinary fish oil is about 30%, and the rest is other fats. The human body cannot synthesize omega 3 fatty acids on its own, it must be obtained from food, and fish oil contains two of the most important omega 3 fatty acids for the human body, namely EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) .
What are the nutrients in fish oil?
Fish oil is a general term for all oily substances in fish extracted from marine fish fat, including fish body oil, liver oil and brain oil. Fish oil is obtained by cooking, pressing and separating fish meat and its internal organs. The main components of fish oil are polyunsaturated fatty acids, of which omega-3 polyunsaturated fatty acids are the main components, commonly known as DHA and EPA.
Fish oil contains two main substances, DHA and EPA.
Currently, it is internationally recognized that EPA and DHA can significantly reduce blood lipids, promote the development of the brain nervous system, and regulate immune function. EPA is mainly used to regulate blood lipids and triglycerides, while DHA mainly acts on the brain.
However, the DHA and EPA of deep sea oils can vary depending on the source of extraction. Generally speaking, there are three types of fish oil, tuna oil and algae oil.
