Topic: Vitamin poisoning


  
 Vitamin - Wikipedia, the free encyclopedia
Vitamins can be classified as either water soluble, which means they dissolve easily in water, or fat soluble, which means they are absorbed through the intestinal tract with the help of lipids.
The reason the alphabet soup of vitamins seems to skip from E to the rarely-mentioned K is that most of the "letters" were reclassified, as with fatty acids, discarded as false leads, or renamed because of their relationship to "vitamin B", which became a "complex" of vitamins.
Vitamins A, D, E, and K are fat soluble, while the water-soluble vitamins include vitamin C and the B-complex vitamins (thiamine (B1), riboflavin (B2), niacin (B3), pantothenic acid (B5), vitamin B6, vitamin B12, biotin and folate.

 Vitamin poisoning - Wikipedia, the free encyclopedia
Vitamin poisoning, or hypervitaminosis, refers to a condition of high storage levels of vitamins, which can lead to toxic symptoms.

 Vitamin poisoning - Encyclopedia, History, Geography and Biography
Vitamin C has been used in dosages over 100,000 mg for serious illness [1] — over 1000 times the daily recommended intake — without ill effects.
Vitamin C does have a pronounced laxative effect, typically in the range of 5-20 grams per day for a person in normal "good health".
This compares with 59 deaths due to aspirin poisoning in 2003, 147 deaths associated with acetomenophen containing products in 2003, and an average of 54 deaths per year due to lightning for 1990-2003.

 Vitamin toxicity
Vitamins vary in the amounts that are required to cause toxicity and in the specific symptoms that result.
Vitamin A and vitamin D are the most likely to produce hypervitaminosis in large doses, while riboflavin, pantothenic acid, biotin, and vitamin C appear to be the least likely to cause problems.
Thus, large doses of vitamin E consumed over many weeks or months might result in deficiencies of vitamin D, vitamin A, and vitamin K. Prolonged consumption of megadoses of vitamin K (menadione) results in anemia, which is a reduced level of red blood cells in the bloodstream.

 Healthnotes Newswire: Vitamin A Supplementation Does Not Cause Osteoporosis
Previous studies showed that increasing vitamin A intake is associated with an increased risk of hip fracture; however, the relevance of those studies is questionable.
As pointed out in Healthnotes Newswire (January 31, 2002), the main sources of vitamin A in the diet are vitamin A-fortified foods such as margarine, sugary breakfast cereals, and milk and circumstantial evidence suggests that some or all of these foods can promote the development of osteoporosis for reasons unrelated to their vitamin A content.
Although taking too much vitamin A can cause a wide range of adverse effects (including neurological disease, liver damage, and even death), bone loss has not been mentioned as a consequence of chronic vitamin A poisoning.
