Vitamin supplements can provide real benefits, but they are often abused and the dangers are real

A new case report provides a striking example of what can happen if one takes too much vitamin D.

A middle-aged man was referred to the hospital by a general practitioner after experiencing vomiting, nausea, abdominal pain, leg cramps, tinnitus, dry mouth, increased thirst, diarrhea, and weight loss. The patient was taking a cocktail of vitamin supplements, including vitamin D 150,000 IUโ€”the daily requirement is 10 mcg or 400 IU.

Although the study documents an extreme case, Dr. Clifford J. Rosen, faculty scientist and director of the Center for Clinical & Translational Research at Maine Medical Center Research Institute, who was also not involved in the study, told MNT that exceeding the recommended amounts of vitamins can cause significant health problems.

Dr. Rosen is among those unconvinced that the popular concern over vitamin D is fully warranted, calling vitamin D โ€œa religion.โ€

โ€œ97.5% of people are vitamin D sufficient; there is no reason to supplement unless there is a medical need due to lack of sunlight or malabsorption,โ€ he told MNT.

He also asserts, โ€œThere is no such thing as vitamin D insufficiency; severe vitamin D deficiency is the only category that counts, with levels less than 10 ng/ml [nanograms per milliliter].โ€
