Official Answer by Drugs.com

Vitamin D has very few side effects when taken at dosages recommended for your age. Side effects are more likely if you take too much vitamin D in the form of supplements, which would then increase your absorption of calcium. These side effects may include:

Abnormal heart rhythms
Bone pain
Confusion or disorientation
Constipation
High blood calcium levels
Kidney stones
Muscle weakness or fatigue
Nausea
Poor appetite
Stomach pain.

Vitamin D is an important vitamin for good bone health. It helps with the absorption of calcium and the regulation of other minerals in the body. Without it, bones will become fragile, misshapen and soft, known as rickets in children and osteomalacia in adults. Vitamin D deficiency has also been associated with some cancers, heart disease, depression, and weight gain.

We make vitamin D in our skin when it is exposed to sunlight; however, people who are institutionalized or immobile, spend most of their time indoors, with dark skin, or cover their skin for religious reasons are at risk of vitamin D deficiency.
