Is that possible to overdose on vitamins? |
Yes, on both vitamins and mineral--- especially vitamin A. Water soluble vitamins - such as the B group vitamins and vitamin C - cannot be stored by the body to any great extent, so if you take in more than your body needs, they are simply excreted. However, the fat soluble vitamins A and D can accumulate in the body, but pose no danger to your health if consumed within the safe upper limits indicated for them. The exception is in pregnancy, when large amounts of vitamin A may pose a risk to the developing infant.
Here are some effects of different vitamins/minerals if taken too much...
Vitamin A
Gorging on this vitamin compound in doses of more than 25,000 IUs (five times the RDA) can lead to liver damage, hair loss, blurred vision and headaches.
Bitamin B-6
Ingesting more than 400 mg a day (200 times the RDA) can cause numbness in the mouth and hands and difficulty in walking.
Vitamin C
It was once believed to cause kidney stones, but experts now say there is no solid evidence of dangerous side effects from vitamin C. High doses can produce stomachaches and diarrhea.
Vitamin D
In daily doses of 50,000 IUs (125 times the U.S. RDA), the sunshine vitamin can cause the buildup of calcium deposits that can interfere with the functioning of muscles, including heart tissue. While sunbathing will never create an overdose, taking too many supplements can.
Vitamin E
Can increase risk for heart attack.
Niacin (B3)
Doctors prescribe doses of 2,000 mg (100 times the RDA) to help lower cholesterol. But patients who take that much should be monitored for possible symptoms of jaundice and liver damage.
Iron
Those who want to bolster their red blood cell count, especially elderly people and menstruating women, have been taking iron supplements for years. Daily doses higher than 100 mg (six times the RDA) could interfere with absorption of zinc, a mineral that speeds wound healing and helps regulate the immune system.
Calcium
Though clearly beneficial in amounts higher than the current RDAs, calcium is not problem-free. here are some symptoms of calcium excesses:
Constipation, bloating, nausea, and intestinal gas are common side effects among healthy people taking supplements equal to 1,500 to 4,000 milligrams of calcium a day.
Doses higher than 4,000 milligrams a day may be linked to kidney damage.
Megadoses of calcium can bind with iron and zinc, making it harder for your body to absorb these two essential trace elements.
Phosphorus
Too much phosphorus can lower your body stores of calcium.
Magnesium
Megadoses of magnesium appear safe for healthy people, but if you have kidney disease, the magnesium overload can cause weak muscles, breathing difficulty, irregular heartbeat and/or cardiac arrest (your heart stops beating).
Zinc
Moderately high doses of zinc (up to 25 milligrams a day) may slow your body’s absorption of copper. Doses 27 to 37 times the RDA (11 mg/males; 8 mg/females) may interfere with your immune function. Gram doses (2,000 milligrams/2 grams) of zinc cause symptoms of zinc poisoning: vomiting, gastric upset, and irritation of the stomach lining.
Iodine
Overdoses of iodine cause goiters. When you consume very large amounts of iodine, the mineral stimulates your thyroid gland, which swells in a furious attempt to step up its production of thyroid hormones. This reaction may occur among people who eat lots of dried seaweed for long periods of time.
Selenium
Nutrition researchers have linked doses as high as 5 milligrams of selenium a day to thickened but fragile nails, hair loss, and perspiration with a garlicky odor. In the United States, a small group of people who got a mislabeled supplement that contained 27.3 milligrams selenium (436 times the RDA) suffered selenium intoxication — fatigue, abdominal pain, nausea and diarrhea, and nerve damage.
Fluoride
Large doses of fluoride — which you’re unlikely to consume unless you drink well or groundwater in the western United States — causes fluorosis (brown patches on your teeth), brittle bones, fatigue, and muscle weakness. Over long periods of time, high doses of fluoride may also cause little bumps of bone on the spine.
