Vitamin A is fat soluble. This means that excess is stored in the body for longer periods of time. This also means that there is a greater risk of toxicity when eaten in large amounts.
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.
The animal form of Vitamin A is what is toxic to a human in overdose. The vegetable form has no toxicity level. The FDA recommends you don't consume over 10,000 IU per day.
Fat soluble vitamins are not as quickly eliminated from the body, but rather are stored in fat tissues and in various organs throughout the body. The regulation of the body levels of these vitamins is therefore not as precise as for the water soluble vitamins and long term consumption at levels above those required can mean the build up of toxic levels of fat soluble vitamins in the body. Toxic symptoms have been recorded but for some fat soluble vitamins such as vitamin E and vitamin K it has been difficult to establish the effects of chronic (long term) consumption levels.
Vitamin A has the highest toxicity potential of the Fat soluble vitamins as too much can cause weakened bones and increased fractures. The male and female daily required intakes is 900 and 700 mcg respectively, whereas the upper tolerable limit is around 3,000 mcg.
Vitamin toxicity can be prevented by minimizing the use of vitamin supplements.
In all cases, treatment of vitamin toxicity requires discontinuing vitamin supplements.
The prognosis for reversing vitamin toxicity is excellent for most patients
The diagnosis of vitamin toxicity is usually made on the basis of the patient's dietary or medical history.
Vitamin toxicity is a condition in which a person develops symptoms as side effects from taking massive doses of vitamins.
called hypervitaminosis or vitamin poisoning
None of the water soluble vitamins (e.g. B complex, C) can produce toxicity.Niacin, one of the B vitamins does produce a very unpleasant "flushing" at very high doses, but although unpleasant is not a result of toxicity. However these high doses of niacin should only be under a doctor's supervision.
