Introduction
Fish liver oil is mainly derived from extracts of deep-sea fish livers. It typically offers benefits such as promoting cardiovascular health, exerting anti-inflammatory effects, supporting bone health, promoting eye health, and enhancing immune function. Excessive intake may lead to adverse symptoms such as dizziness, diarrhea, and nausea. Therefore, it is best to consult a physician before use and follow the recommended dosage and usage instructions.

     Fish liver oil is mainly derived from extracts of the livers of deep-sea fish and typically offers various health benefits, including promoting cardiovascular health, exerting anti-inflammatory effects, supporting bone health, promoting eye health, and enhancing immunity. A detailed analysis is as follows:

     1. Promoting cardiovascular health

     Omega-3 fatty acids in fish liver oil can lower blood triglyceride levels, reduce the risk of atherosclerosis and thrombosis, thereby benefiting heart health. In addition, they may also help control hypertension.

     2. Anti-inflammatory effects

     Omega-3 fatty acids in fish liver oil, such as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), have potent anti-inflammatory effects. They can reduce inflammation levels and combat chronic inflammation, potentially lowering the risk of diseases such as heart disease and arthritis.

     3. Supporting bone health

     Fish liver oil contains abundant vitamin D, which promotes calcium absorption and is beneficial for the healthy development of bones and teeth. Adequate vitamin D levels help prevent osteoporosis and fractures.

     4. Promoting eye health

     Vitamin A in fish liver oil is beneficial for eye health and helps maintain normal visual function, especially vision in low light. Vitamin A can also prevent night blindness and other eye diseases.

     5. Enhancing immunity

     Omega-3 fatty acids along with vitamins A and D in fish liver oil all contribute to enhancing immunity. Omega-3 fatty acids can promote the production and activity of white blood cells, improving the body's resistance. Vitamins A and D can improve immune cell function and promote metabolism, further enhancing disease resistance.

     However, excessive intake may cause adverse symptoms such as dizziness, diarrhea, and nausea. Therefore, it is best to consult a doctor before use and follow the recommended dosage and instructions.
