Risk of taking artificial multivitamin

 Risk of taking an artificial multivitamin

Results from many clinical trials show that beta-carotene, vitamin E, and possibly high doses of vitamin A can increase the risk of premature death. Other studies have linked multivitamin use to increased cancer risk, and iron supplements can be harmful to people who don't need them.

A 2013 editorial in the Annals of Internal Medicine found that daily multivitamins don't prevent chronic disease or death, and their use can't be justified — unless a person is below science-based requirement levels.

Mega-doses of vitamins A, D, E, and K can cause health problems, says Consumer Reports, and may interfere with other prescription medications people are taking. Too much vitamin A (in its retinol form) may lead to liver failure or even death, while pregnant women may risk birth defects.

Dietary supplements, such as over-the-counter multivitamins, do “more harm than good” and can increase the risk of developing cancer and heart disease, according to research in the US.

Unlike drugs, supplements are not permitted to be marketed for the purpose of treating, diagnosing, preventing, or curing diseases. That means supplements should not make disease claims, such as “lowers high cholesterol” or “treats heart disease.” Claims like these cannot be legitimately made for dietary supplements.

routinely getting an overload of vitamins and minerals can hurt you. Too much vitamin C or zinc could cause nausea, diarrhea, and stomach cramps. Too much selenium could lead to hair loss, gastrointestinal upset, fatigue, and mild nerve damage.

Most people do not need to take vitamin supplements and can get all the vitamins and minerals they need by eating a healthy, balanced diet. Vitamins and minerals, such as iron, calcium and vitamin C, are essential nutrients that your body needs in small amounts to work properly.

People who smoke or have lung cancer should think twice about taking vitamin supplements, according to a Swedish study Wednesday that showed certain antioxidants may make tumors grow faster.

Overall, women who reported taking multivitamins were 19% more likely to develop breast cancer than their counterparts who said they did not take daily multivitamins.
