Vitamin e
Certain fat-soluble vitamins like vitamins A, D, E, and K can cause toxicity symptoms when consumed in excess. Vitamin A toxicity can lead to problems with vision, skin, and bone health. Vitamin D toxicity can cause hypercalcemia and vitamin E excess may impair blood clotting. Vitamin K excess can interfere with anticoagulant medications.
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.
To reduce excess vitamin A in the body, it is best to avoid high vitamin A foods and supplements, as well as consult a healthcare professional for guidance. Increasing water intake can also help flush out excess vitamin A through urine. It is important not to self-diagnose or self-treat for vitamin A toxicity.
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.
It is recommended not to exceed 3,000 mcg (10,000 IU) of vitamin A per day from supplements to avoid toxicity. Consuming excessively high levels of vitamin A over a long period of time can lead to symptoms such as nausea, headaches, dizziness, and liver damage. It is important to consult with a healthcare provider before taking high doses of vitamin A.
Vitamin toxicity can be prevented by minimizing the use of vitamin supplements.
In all cases, treatment of vitamin toxicity requires discontinuing vitamin supplements.
