Cod liver oil mainly contains vitamin A and vitamin D. Among them, the main function of vitamin D is to promote calcium absorption, which is good for bone development, while vitamin A is an important nutrient element that constitutes the photoreceptors of the retina, and also plays an important role in maintaining the health of the tears and the eye surface, so oral intake of cod liver oil is good for the eyes.
If you are deficient in vitamin A, you may suffer from night blindness, dry eye, corneal softening and other diseases. Not being picky about what you eat, ensuring a balanced diet, and consuming vitamin A-rich vegetables, fruits, milk, eggs, meat, and animal offal can satisfy your body’s needs. If you can’t get enough vitamin A from food or if the disease is caused by deficiency, you need to utilize medication to supplement it.
Cod liver oil is not suitable for everyone and the need to take it should be confirmed by a doctor and care should be taken not to overdose.
