Vitamin D

Side Effects: A vitamin D deficiency can lead to osteoporosis in adults or rickets in children. Excessive doses of vitamin D can result in increased calcium absorption from the intestinal tract. This may cause increased calcium resorption from the bones, leading to elevated levels of calcium in the blood. Elevated blood calcium may then cause calcium deposition in soft tissues such as the heart and lungs. This can reduce their ability to function.
