Deep-sea fish oil belongs to health care products, and its nutritional components are ω-3 polyunsaturated fatty acids, mainly containing DHA and EPA, without any harm. The American Heart Association's assessment of the safety of fish oil found that it is generally safe and well tolerated to ingest omega -3 within 3 g per day, so it is safe to eat high-purity deep-sea fish oil for a long time because the amount of omega -3 is controlled at 3 g.

The adverse reactions of high-purity deep-sea fish oil are slight digestive tract problems such as nausea and burping. However, the side effects of some low-purity fish oil in the market cannot be guaranteed. In addition to omega -3, low-purity fish oil also contains other ineffective or even harmful components such as saturated fat, so attention should be paid to screening when choosing fish oil. Eating deep-sea fish oil is good for your health. The biggest advantage is to strengthen your brain and improve your intelligence. DHA in deep-sea fish oil is a special unsaturated fatty acid, which is indispensable for the formation and development of brain cells.

Therefore, supplementing deep-sea fish oil can enhance people's memory and concentration. Deep-sea fish oil also has certain protective effect on cardiovascular and cerebrovascular diseases. Unsaturated fatty acids contained in deep-sea fish oil are beneficial to remove cholesterol and atherosclerotic plaques on blood vessel walls, so it can effectively prevent coronary atherosclerotic heart disease and prevent myocardial infarction caused by the shedding of coronary atherosclerotic plaques. In addition, deep-sea fish oil can enhance human immunity.

However, deep-sea fish oil should not be taken for a long time or in large quantities, because it will increase the calorie intake in the body and lead to obesity. Long-term use of deep-sea fish oil will also lead to high cholesterol.

In addition, people who are allergic to seafood should carefully choose fish oil.
