Is cod liver oil vitamin d?

Cod liver oil is not vitamin D.

Cod liver oil is an oil extracted from fish liver, which contains vitamin A and vitamin D. Vitamin D is a fat-soluble vitamin, which has important physiological functions in the human body, such as promoting calcium absorption and utilization, maintaining bone health, etc.

Although cod liver oil contains vitamin D, its content is relatively low, and cod liver oil also contains other ingredients, such as vitamin A, cholesterol, etc. Therefore, if vitamin D needs to be supplemented, it is not recommended to rely solely on cod liver oil, but to choose the appropriate vitamin D supplement according to individual conditions.

In addition, it should be noted that excessive intake of vitamin D may also cause adverse health effects, such as poisoning. Therefore, when supplementing vitamin D, you should follow the advice of your doctor or nutritionist and supplement according to the prescribed dosage.
