 Is it ok to take vitamin supplements every day?

There actually can be too much of a good thing, and anything in excess — whether vitamins, supplements or food — can cause serious problems. In terms of vitamins, some are fat-soluble, meaning they are stored in the liver, and you don't need them every day, while others are water-soluble, and need to be replenished."Most people think it's fine to take as much as they want," says Rosenbloom. "I know people who take 10,000 mg a day." However, the upper tolerable limit is 2,000 mg a day. "People at risk for kidney stones can increase that risk; people also can get diarrhea.

 Although vitamin supplements are safely consumed by many people on a daily basis, it's possible to take too high of a dose, which can result in adverse side effects. Overdosing on certain vitamins can lead to serious complications and, in rare circumstances, even death.

The fat-soluble vitamins, A, D, E, and K, are stored in the body for long periods of time and generally pose a greater risk for toxicity than water-soluble vitamins when consumed in excess. Eating a normal, well-balanced diet will not lead to toxicity in otherwise healthy individuals.

The majority of vitamins and other nutritional supplements don't increase lifespan or protect one's heart health, a huge analysis out of Johns Hopkins University has found.

There's even more evidence to suggest popular vitamin supplements are essentially useless. A new study suggests that popular vitamin supplements are mostly useless. The most popular vitamin supplements, including vitamin C and calcium, don't really have major health benefits, the study found.

You may need to avoid some vitamins and minerals if you have kidney disease. Some of these include vitamins A, E and K. These vitamins are more likely to build up in your body and can cause harm if you have too much. Over time, they can cause dizziness, nausea, and even death.High doses of vitamin E may lead to stroke caused by bleeding in the brain.

While vitamins are an important weight gain-promoting factor, at toxic levels they are no longer associated with weight gain or even cause weight loss. It has long been known that many micronutrients (vitamins and minerals) are essential for life at low concentrations but become toxic at high concentrations.A 2013 editorial in the Annals of Internal Medicine found that daily multivitamins don't prevent chronic disease or death.

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.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.

What's more, the body can become dependent on high doses of vitamins, she says. When you stop, the body is no longer efficient at absorbing them from food and you can become nutrient deficient, even though your diet may be good. So if you're going to take vitamins, be warned.

"Not only are vitamin and mineral supplements a waste of money, they can in some instances actually harm the body," reports The Guardian

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.

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 for people who don't need them 

Do multivitamins actually work?

No, Say Scientists. Popping vitamins and mineral supplements might feel virtuous, but it actually carries surprisingly few health benefits and could even do harm, according to researchers.
