What vitamins cause skin yellow skin?

Vitamin A

Excessive consumption of vitamin A, particularly in the form of supplements, can lead to carotenemia, a condition characterized by yellowing of the skin. Carotenoids, including beta-carotene, are pigments found in many fruits and vegetables, and they are responsible for the yellow, orange, and red colors of these foods. When consumed in large amounts, carotenoids can accumulate in the skin, leading to a yellowish discoloration.

Vitamin B12

Vitamin B12 deficiency can cause a condition called pernicious anemia, which can lead to yellow skin. Pernicious anemia is a type of anemia that occurs when the body is unable to absorb vitamin B12 from food. Vitamin B12 is essential for the production of red blood cells, and a deficiency can lead to a decrease in the number of red blood cells, resulting in anemia. Anemia can cause the skin to appear pale or yellow.

It's important to note that yellow skin can also be caused by other factors, such as liver disease, kidney disease, and certain medications. If you notice yellowing of the skin, it's important to see a doctor to determine the cause and receive appropriate treatment.
