The D Stands for Vomiting
Nutritional supplements can be useful for people with documented deficiencies and certain health conditions, such as pregnancy. But for the average person, supplements haven’t been shown to have much benefit. And rarely, they can have downright dangerous side effects.
In July, UK doctors documented the case of a man who severely overdosed on vitamin D supplements, causing him to develop symptoms like diarrhea, abdominal pain, tinnitus, and incessant vomiting for nearly three months; the man also lost 30 pounds in that time. He ended up in the hospital for 8 days, where he was given treatment to reduce his high calcium levels (another side effect of the supplements). Two months later, his calcium supply had returned to near normal, though he still had high amounts of vitamin D in his system.
