That is good information. Here's an example of a vitamin D overdose:
>>>A British man's overdose on vitamin D is a cautionary tale for people who are considering adding supplements to their lives, according to a paper published Tuesday in the journal BMJ Case Reports.
After a visit with 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 suffering from nausea, abdominal pain, diarrhea and repeated bouts of vomiting, along with cramping in the legs and ringing in the ears. . . .
The man stopped taking the supplements when his symptoms began, but his condition didn't improve. By the time he was referred to the hospital two months later, he had lost 28 pounds (12.7 kg) and his kidneys were in trouble. Tests showed he had overdosed on vitamin D, a condition called hypervitaminosis D. . . .
Too much vitamin D in the blood leads to hypercalcaemia, which occurs when the calcium level in your blood is above normal. The man in the BMJ case study was diagnosed with hypercalcaemia, which can weaken your bones, create kidney stones, and interfere with how your heart and brain work.
The man was hospitalized for eight days and treated with drugs to lower the levels of calcium in his blood. A followup two months later found his blood calcium levels had dropped to almost normal. While the man's vitamin D level had also significantly improved, it was still high, Alkundi said.<<<
A private nutritionist told a British man to take large doses of vitamin D along with other supplements. It didn't go well.
