At present, fish oil products on the market are mainly divided into ordinary fish oil and deep-sea fish oil. Common fish oil is fish fat from offshore fish and river fish. Deep-sea fish oil is fat extracted from deep-sea fish (marine fish living in deep-sea areas below 100 meters), such as fish in the icy waters of Alaska's deep sea.
Both common fish oil and deep sea fish oil can be eaten. Deep-sea fish oil in the market is often more expensive than ordinary fish oil. Some people think that the more expensive deep-sea fish oil is better than ordinary fish oil, but in fact, the effective components of both are DHA and EPA.
The price difference is mainly due to the difficulty in fishing deep-sea fish, long growth cycle, high cost and high production price of fish oil, but the quality of fish oil can not be judged by the price alone.

Some misunderstandings about fish oil
1, fish oil is not equal to cod liver oil.
Fish oil is an extract of fatty fish and belongs to unsaturated fatty acids. Its main components are DHA and EPA, which can reduce triglycerides in blood. Cod liver oil is fat extracted from the liver of fish. Its main components are vitamin A and vitamin D, which are often used to prevent night blindness and rickets.
Fish oil is not suitable for anyone.
If it is for daily health care, people can get enough DHA and EPA from fish. If you eat little or no fish in your daily diet, you can consider using fish oil supplements, but the FDA recommends that you eat no more than 3 grams a day.
If it is to reduce blood fat, improve heart rate and prevent coronary heart disease, please consult your doctor about the dosage of fish oil. If you have diabetes or blood coagulation disorder, you should use fish oil carefully. You must consult your doctor before deciding whether to take it.
