What are the side affects of vitamin d? (In pill form)
Not Medical Advice: There is very little chance of overdosing on vitamin D from sunlight or from foods, unless you consume too much cod liver oil. Too much vitamin D in pill form can result in kidney stones, high blood calcium level, nausea, constipation, abnormal heart rhythm, and confusion. On the other hand, too little vitamin D may cause bone pain and softening, and skeletal deformities. Recent studies show that vitamin D consumed in a balanced diet may help prevent cancer, high blood pressure, osteoporosis, and some autoimmune diseases.
