Among some cases, there was one in particular of a young man of 18 years, who suffered from diarrhea and stomach pains for three consecutive months after consuming 50,000 IU of vitamin D3 daily for the same period of time. After stopping the treatment, the stomach discomfort suddenly stopped at the same time.
5.It gives rise to kidney complications

In one case studied there was a patient who was hospitalized for presenting kidney lesions. When evaluated by the doctors, it was determined that he had high levels of calcium in the blood. The most curious thing of the case (but with a lot of sense) is that the patient had received several injections of vitamin D previously, all prescribed by his doctor.
If you suffer from kidney disease, or want to prevent some damage to your kidneys, it is best to avoid excessive consumption of vitamin D. Of course, this does not mean you cannot consume it, but be careful not to exceed the recommended levels.
