Effects of Vitamin D Overdose
A British man's vitamin D overdose is a warning to people considering adding vitamin supplements to their lives, according to an article published Tuesday in the journal BMJ Case Reports. After a visit to a private nutritionist, the man began taking more than 20 over-the-counter supplements every day, including 50,000 international units (IU) of vitamin D three times a day. That's a dose hundreds of times higher than standard nutritional recommendations. Within a month, the man began to experience nausea, abdominal pain, diarrhea and repeated bouts of vomiting, as well as leg cramps and ringing in his ears.
The man, whose name was not released, learned about the supplements on a radio talk show and then contacted the show's nutritionist, said Dr. Alamin Alkundi, a co-author of the report and an endocrinologist at William Harvey Hospital in East Kent. in the UK, who treated the man.
"Regulatory registration is not compulsory for nutritionists in the UK and their title is not protected, so anyone can practice as a nutritionist," Alkundi said in an email. Vitamin D and fish oil supplements may help prevent autoimmune diseases, study says.

The man in the case study was taking a daily dose of 150,000 IU of vitamin D, which was "375 times the recommended amount," Alkundi said. The UK National Health Service normally recommends 400 IU of vitamin D a day for children over 1 year of age and adults.
The man stopped taking the supplements when his symptoms began, but his condition did not improve. When he was referred to the hospital two months later, he had lost nearly 30 pounds and his kidneys were in trouble. Tests showed that he had overdosed on vitamin D, a condition called hypervitaminosis D.

For adults 70 years of age and older, the dose is increased to 20 micrograms or 800 IU per day. The recommended amount for infants, children and adolescents was recently doubled by the American Academy of Pediatrics (AAP) to 10 micrograms or 400 IU per day.
