Vitamin D is the most potentially toxic of all vitamins. The security system on this website has been activated. Completing the next challenge proves that you're a human being and gives you temporary access. Because of their ability to accumulate in the body, fat-soluble vitamins have a greater potential for toxicity than water-soluble vitamins..
Iron-containing vitamins are the most toxic, especially in acute pediatric ingestion. See Prognosis, Evaluation, Treatment, and Medication. Signs of vitamin D toxicity include excess calcium in the blood, delayed physical and mental growth, decreased appetite, nausea, and vomiting. However, taking vitamin supplements that contain large doses of vitamins A, D, E, and K can cause toxicity.
Fat-soluble vitamins, A, D, E, and K, are stored in the body for long periods of time and generally pose a greater risk of toxicity than water-soluble vitamins when consumed in excess. However, doctors are seeing an increase in the number of patients experiencing toxicity from taking more vitamin supplements than necessary. Isotretinoin (Accutane), a medication used to treat severe forms of acne, is closely related to the chemical structure of vitamin A, meaning that the pharmacology and toxicology of these two compounds are similar. However, the U.S.
Food and Drug Administration (FDA) has banned vitamin K3 (menadione) supplements due to its high toxicity. It may also have a therapeutic role as adjunctive therapy for the treatment of methanol toxicity, as it improves the elimination of formate. To prevent vitamin toxicity, patients should visit their primary care physician to determine if they really have a deficiency to correct and what supplements can safely benefit them. As it is fat-soluble, vitamin A is stored to a varying degree in the body, making it more likely to cause toxicity when taken in excessive amounts.
The diet is highly unlikely to cause vitamin toxicity, unless you consume a lot of fortified foods or protein shakes with added vitamins. Patients with vitamin E toxicity who develop intracranial bleeding have a higher mortality rate. These vitamins can remain in the body for up to six months, accumulate and reach potentially toxic levels. Vitamin A toxicity can also cause serious birth defects and increase the risk of bone loss and hip fractures.
