The Role of Fish Liver Oil

Cod liver oil is an oil rich in vitamins A and D, extracted from the livers of fish. Its main health benefits include: 1. **Vitamin A supports vision**: The vitamin A in cod liver oil helps maintain eye health and prevents night blindness and dry eye syndrome. 2. **Promotes bone health**: Vitamin D also plays an important role in cod liver oil, aiding the body's absorption of calcium and phosphorus, thus supporting bone growth, maintaining bone density, and preventing osteoporosis. 3. **Strengthens the immune system**: Both vitamins A and D are essential nutrients for the normal functioning of the immune system, helping to enhance the body's resistance to disease. 4. **Supports nervous system development**: For pregnant women and children, an adequate amount of vitamin D has positive effects on the development of the neural tube and the maintenance of brain function. It should be noted that although cod liver oil offers many benefits, excessive intake may lead to vitamin A and D toxicity. Therefore, recommended dosages should be followed when taking supplements, and they should be taken under the guidance of a physician.
