Introduction
Under normal circumstances, fish liver oil is not vitamin AD. The specific analysis is as follows: although fish liver oil and vitamin AD share similar main components, the difference lies in their sources—fish liver oil is natural, whereas vitamin AD is synthetic. Fish liver oil is directly extracted from the livers of fish, making it a natural substance that supplements the body's vitamin AD derived from animal tissues.

Generally speaking, fish liver oil is not the same as vitamin AD. The detailed explanation is as follows:

Fish liver oil and vitamin AD have similar main components, but the difference lies in their sources—fish liver oil is natural, while vitamin AD is synthetic. Fish liver oil is extracted directly from the livers of fish, making it a natural substance that supplements the body's vitamin A and D. In contrast, vitamin AD is a man-made product with the same primary components as fish liver oil, used to supplement the body’s needs for vitamins A and D. It is typically synthesized in a 3:1 ratio of vitamin A to vitamin D and is referred to as "synthetic vitamin AD oil." However, individuals who are allergic to seafood should avoid fish liver oil and instead take vitamin AD or vitamin D supplements directly.

If a patient experiences any discomfort, it is recommended to seek medical attention at a hospital promptly to avoid delaying treatment.
