What happens if there is too much or too little vitamin D in the body?

Answer 1

If you get too much Vitamin D, you can become toxic. Symptoms of Vitamin D toxicity are:• abdominal cramps

• nausea

• frequent urination

• weakness

• nervousness

• itching

• and eventually kidney failure

They will find high levels of calcium in your blood which is a hallmark of vitamin D overdose.

However, it's harder to get too much vitamin d than most people think, doctors included. Vitamin D toxicity is VERY rare and most cases have occurred from industrial accidents where dairies or bread companies accidentally fortified their foods with way too much vitamin D.

Cases of adults with toxicity from supplements almost never occur with less than 10,000 IU's of Vitamin D every day for long periods of time, and most occurred with more than 25,000 IU's a day over an extended period.

There has never been a case of vitamin D toxicity from the sun.

Answer 2

Too much Vitamin D rare, as you do not have much of it in diet or after exposure to morning sun light, it does not give toxic doses of Vitamin D. If you eat too much of Vitamin D, say 50,000 International Units/ day for several months, then you may get toxicity of Vitamin D or happen to eat too much of shark liver in your diet. You will get fatigue, nausea , vomiting, loss of appetite and there will be wide spread calcification in soft tissue. With too less Vitamin D, witch is very common, in young age you get Rickets and in adults osteomalacia, with soft bones, decreased absorption of Calcium from intestine and decreased re absorption of Calcium salts from kidney.
