The average time people stuck with it was about two and a half years. The same study, however, had previously found that multivitamins might modestly reduce the risk of cancer and cataracts.

In a strongly worded editorial on the three studies, Guallar and his co-authors urged people to stop spending money on multivitamins. These daily multivitamins are formulated to help your pet reach peak health as he grows and ages.

Dietary supplements are a multibillion-dollar industry in the United States, and multivitamins account for nearly half of all vitamin sales, according to the U.S. Office of Dietary Supplements.

A study published in 2007 from the US National Cancer Institute, for instance, found that men that took multivitamins were twice as likely to die from prostate cancer compared to those who didn’t. And in 2011, a similar study on 35,533 healthy men found that vitamin E and selenium supplementation increased prostate cancer by 17%. Just seven studies reported that supplementation led to some sort of health benefit from antioxidant supplements, including reduced risk of coronary heart disease and pancreatic cancer.

Third, and crucially to avoid unintentional bias, no one knows who was given which until after the trial; not even those administering the treatment. Sales in multivitamins and other dietary supplements boomed, as did Pauling’s fame. Participants were asked to take six large pills a day, and researchers think many developed pill fatigue. Nearly half the participants in each part of the study stopped taking their medication before the end of the study.

The premise is pretty simple. First, find a group of people similar in age, location, and lifestyle. Second, split them into two subgroups. One half receives the supplement you’re interested in testing, while the other receives a blank – a sugar pill, a placebo.

It gets worse. One study of more than 1,000 heavy smokers published in 1996 had to be terminated nearly two years early. After just four years of beta-carotene and vitamin A supplementation, there was a 28% increase in lung cancer rates and a 17% increase in those who died. A similar result was found in postmenopausal women in the U.S.

Over the years, vitamin C, and many other dietary supplements, have found little backing from scientific study. In fact, with every spoonful of supplement he added to his orange juice, Pauling was more likely harming rather than helping his body. His ideas have not just proven to be wrong, but ultimately dangerous. But a growing body of evidence suggests that multivitamins offer little or nothing in the way of health benefits, and some studies suggest that high doses of certain vitamins might cause harm. MONDAY, Dec. 16, 2013 (HealthDay News) -- With three new studies finding that a daily multivitamin won't help boost the average American's health, the experts behind the research are urging people to abandon use of the supplements.

After 10 years of taking folic acid (a variety of B vitamin) every day their risk of breast cancer increased by 20% relative to those women who didn’t take the supplement. In 1994, for example, one trial followed the lives of 29,133 Finish people in their 50s. All smoked, but only some were given beta-carotene supplements. Within this group, the incidence of lung cancer increased by 16%.

Preventive Services Task Force, found no evidence that supplements offer a benefit for heart disease or that they delay death from any cause. They found only a minimal benefit for cancer risk. We’ll never know for sure. But given that multiple studies have linked excess antioxidants to cancer, it certainly isn’t out of the question.

A study published in 2007 from the US National Cancer Institute, for instance, found that men that took multivitamins were twice as likely to die from prostate cancer compared to those who didn’t. And in 2011, a similar study on 35,533 healthy men found that vitamin E and selenium supplementation increased prostate cancer by 17%. Just seven studies reported that supplementation led to some sort of health benefit from antioxidant supplements, including reduced risk of coronary heart disease and pancreatic cancer.

Simply provide an email address below. The third study, a research review, assessed the evidence from 27 studies on vitamin and mineral supplements that included more than 450,000 people. That study, conducted for the U.S.

Ten studies didn’t see any benefit at all – it was as if all patients were given the sugar pill also (but, of course, they weren’t). That left another 10 studies that found many patients to be in a measurably worse state after being administered antioxidants than before, including an increased incidence of diseases such as lung and breast cancer. But his academic reputation went the other way.

It was the fourth most popular supplement in a ConsumerLab survey of its readers in 2010, used by 56% of respondents.
