You may not be able to absorb vitamin D if you have certain health conditions. This includes mucus buildup in the intestines and liver problems.
The amount of vitamin D that can be made by the body is limited by factors such as sun exposure, skin pigmentation, age, geographic location, clothing coverage, and the use of sunscreen. Additionally, certain medical conditions or medications can affect the body's ability to produce vitamin D.
Liver disease (such as cirrhosis or hepatitis) is a medical condition that can increase vitamin B12 in the body. Some myeloproliferative disorders (for example, polycythemia vera and chronic myelocytic leukemia or CML) can also increase vitamin B12 in the body. Vitamin B12 excess is virtually harmful since it is a water-soluble vitamin. It will just be secreted from the body as urine. The conditions themselves are what is cause for concern. The increased vitamin B12 can just be used as an indicator for the disease.
The only way to reduce vitamin D in the body is to stop intake of vitamin D.

This nutrient is essential for maintaining healthy vision, particularly in low-light conditions, as it helps form a pigment called rhodopsin in the retina. Additionally, Vitamin A supports overall eye health and may help prevent certain eye conditions. These foods are rich in beta-carotene, which the body converts into Vitamin A.
