Vitamin D Toxicity: 6 Shocking Side Effects Of Hypervitaminosis D

For any casual health buff, vitamin D is an essential. Usually tagged as the healthy “sunshine” vitamin, it’s basically one of the most popular supplements anyone from any age can take, and home refrigerators stacked with a bottle or two of its pills are just about as common as pineapples on pizza. And it’s all for good reason, as it helps your body absorb calcium, which in turn helps your bones grow much stronger.

However, too much of a good thing can be disastrous even when it comes to vitamin, as discovered by a man who suffered from excessive kidney damage after ingesting high amounts of the vitamin.

According to medical experts, the 54-year old Canadian man’s case was a cautionary tale for consumers.

The report was released last April 8 by the CMAJ (Canadian Medical Association Journal), where it was revealed that after the man returned from a Southeast Asian holiday, where he spent most of his time sunbathing, it was discovered that he took in high loads of Vitamin D through sunlight.

So what are the other side effects of too much Vitamin D?

  1. Hypercalcemia – An excess of calcium in the blood, this condition occurs when there are more than 10,400 ng/mL of calcium present in the bloodstream. This in turn, leads to a wider range of complications, which includes anxiety, headaches, nausea and vomiting, diarrhea, muscle weakness and an irregular heartbeat, among many others.
  2. Kidney damage – Too much calcium in our blood can also form crystals that go through our body tissues. These crystals can then cause organ damage, making the kidney as a primary target because it acts as both a filter and passageway. Permanent damage can then lead to kidney failure.
  3. Heart attack – Extreme hypercalcemia can also lead to the development of calcium deposits that block our arteries, leading to either complete heart blockage or in extreme cases, heart attack.
  4. Bone pain/Brittle bones – Too much calcium circulating in the bloodstream also means that there’s not enough hormones to stick the mineral into the bones, which can then lead to long-term problems with the bones.
  5. Dehydration – Another problem that occurs from hypercalcemia is that it can our harm our kidney’s ability to concentrate urine, which then leads to polyuria, where a person passes unusually large amounts of water/urine. This can then turn to extreme dehydration.
  6. Pancreatitis – In extreme cases, hypercalcemia can also lead to the inflammation of the pancreas, or pancreatitis. This leads to weight loss, fever, and upper stomach pain that extends to the back.
