Fish oil, as the name suggests, refers to oil made from fish; unlike cod liver oil, fish oil is fish body oil. Since it is fish body oil, the choice of fish raw materials is quite critical. High-purity Omega-3 deep-sea fish oil has certain health-care functions, which are inseparable from the fat composition and content of the raw fish itself. Freshwater fish has a low content of unsaturated fatty acids and is generally not used as a raw material for fish oil processing; on the contrary, deep-sea fish oil with a high content of omega-3 PUFA is popular. As listed in the table below, deep-sea fish have a high content of unsaturated fatty acids and high nutritional value.

Note: C 18:1, saturated fatty acid.

C 20:5, eicosapentaenoic acid, the EPA in the omega-3 series of polyunsaturated fatty acids.

C 22:6, Docosahexaenoic acid, which is the DHA in the omega-3 series of polyunsaturated fatty acids.

Generally speaking, deep-sea fish generally have high nutritional value, but the nutrients provided by different fishes vary greatly. In the above table, the proportions of EPA and DHA in anchovy in South America are: 17.5% and 10.5%, respectively. We know that EPA has the effect of helping lower cholesterol and triglycerides, while DHA plays a role in vision and intelligence; both can promote the metabolism of human fatty acids and protect the heart and brain blood vessels. The sum of them is the largest among the deep-sea fishes listed in the table, and the fat content of anchovy is the smallest.

The nutritional value of anchovy is obvious. According to data released by the global EPA and DHA organization (GOED), in 2013, the total amount of omega-3 extracted raw materials was as high as 53,000 metric tons. Among them, anchovy is the most widely used raw material for extracting omega-3.

Ouqian 90% Omega-3 high-purity fish oil soft capsule is no exception. Ouqian's raw anchovy comes from Peru, South America, which is rich in anchovy.

In addition, as the deep-sea fish at the lowest end of the food chain, anchovy is the least affected by environmental pollution; the anchovy raw materials of Ouqueen fish oil have also passed the strict EU EMAS (EU Ecological Management and Audit System) sustainable fishing program certification to ensure product nutrition and safety , Environmental protection.
