Seal oil is a well-known health product, mainly rich in unsaturated fatty acids such as DHA and EPA, which can regulate the body’s lipid metabolism and prevent the occurrence of atherosclerosis, and also has a certain effect on inflammation or thrombosis. Seal oil can be taken orally at any time of the day or night. If patients have a history of elevated lipids and atherosclerosis, they can take seal oil appropriately, but do not use seal oil as a medicine for treatment. Because seal oil itself is a health care product, it only plays a proper regulating role, and the main focus is on drug treatment. If the patient has a history of obesity, smoking, alcohol consumption or hypertension or hyperlipidemia, seal oil can be taken appropriately for regulation.
