      Case Is Closed: Multivitamins Are a Waste of Money, Doctors Say

      Case Is Closed: Multivitamins Are a Waste of Money, Doctors Say

      By By Bahar Gholipour, Staff Writer 12 hours ago

      People should stop wasting their money on dietary supplements, some physicians said today, in response to three large new studies that showed most multivitamin supplements are ineffective at reducing the risk of disease, and may even cause harm.

      The new studies, published today (Dec. 16) in the journal Annals of Internal Medicine —including two new clinical trials and one large review of 27 past clinical trials conducted by the U.S. Preventive Services Task Force — found no evidence that taking daily multivitamin and mineral supplements prevents or slows down the progress of cognitive decline or chronic diseases such as heart diseases or cancer.

      "The message is simple: Most supplements do not prevent chronic disease or death, their use is not justified and they should be avoided," the physicians wrote in an editorial published along with the studies.

      This message is especially aimed at people who have no signs of nutritional deficiency — meaning most supplement users in the United States, the researchers said.

      "Study after study comes back negative — yet people continue to take supplements, now at record rates," said Dr. Edgar Miller, one of the five authors of the editorial and a professor of medicine and epidemiology at Johns Hopkins University in Baltimore.

      There may be a psychological component to taking supplements, Miller said. Despite evidence showing supplements hold no benefit for the general population, some people may rationalize they need supplements because their diets lack necessary nutrients, Miller told LiveScience.

      The new findings are in line with those of previously published studies that have found no benefits from dietary supplements, including B vitamins and antioxidants, and even suggested possible harms. Results of clinical trials involving tens of thousands of people have shown that beta-carotene, vitamin E and possibly high doses of vitamin A supplements actually increase death rates, the researchers said.

      "We believe that the case is closed — supplementing the diet of well-nourished adults with most mineral or vitamin supplements has no clear benefit and might even be harmful," the researchers wrote in their editorial.

      The use of multivitamin and mineral supplements among Americans has increased to about 50 percent in the mid-2000s, up from 40 percent in the early 1990s, according to the Centers for Disease Control and Prevention.

      For some supplements, such as beta-carotene and vitamin E, studies have found declines in use, following reports of their negative effects on lung cancer and mortality.

      In contrast, sales of multivitamins and other supplements have not been affected by major studies that didn't find benefits, the researchers said. The U.S. supplement industry continues to grow, and reached $28 billion in annual sales in 2010. Similar trends have been reported in the United Kingdom and in other European countries.

      The dietary-supplement industry maintains that for many Americans, diet alone may not provide the necessary vitamins they need daily, Miller said.

      "The industry tries to create the impression that we are deficient, but randomized trials show that we are not all deficient and we don't benefit from supplements," Miller said, adding that clinical trials include people with varied diets from the general population.

      The new review study looked at clinical trials that included a total of 450,000 older adults. All together, the researchers didn't find clear evidence of a beneficial effect of supplements on cancer and heart diseases.

      In another study, researchers looked at the effects of taking a daily combination of nutrients —including vitamins A, C, E, beta-carotene and B vitamins — in 6,000 men ages 65 and older who were followed for 12 years. The cognitive performance and verbal memory of participants who took multivitamin supplements didn't differ from those of participants who took placebo.

      In the third study, the researchers examined whether high doses of multivitamins and minerals could prevent heart attacks, strokes and death in 1,700 people who have already had a heart attack. After an average follow-up of five years, the results didn't show a difference between participants who took dietary supplements and those who didn't.

      Wasting Money on Supplements

      By Lisa Collier Cool
      Dec 16, 2013

      Many people pop a multivitamin each day, believing they are boosting their health; however, new research suggests that routine dietary supplements may be unnecessary or even harmful.

      In a new editorial in Annals of Internal Medicine (AOIM), physicians urge Americans to “stop wasting money on vitamin and mineral supplements.” The editorialists—referencing new research included in the same issue of the journal—warn that, “[m]ost supplements do not prevent chronic disease or death, their use is not justified, and they should be avoided.” This is especially true for people who lack symptoms of nutritional deficiencies, including most supplement users. In fact, in some cases, supplements may cause harm.

      “We need vitamins and minerals to function,” explains one of the editorialists, Dr. Eliseo Guallar. “So many people think, ‘the more you get, the better you should be.’ But we actually have a lot of accumulated evidence that vitamin supplements aren’t helping. They aren’t working in the general population to prevent chronic disease.”

      Supplements May Not Prevent Cancer, Could Cause Harm

      In a new review article in AOIM, published early online, researchers at the Kaiser Permanente Center for Health Research in Portland, Oregon examined 26 studies of dietary supplements, including single, paired, or multivitamin combinations of nutrients.

      The researchers found no consistent link between supplement use and decreased risk of cancer, heart disease, or all-cause mortality. Only two studies showed a potential link between multivitamin use and cancer prevention among men. However, the statistical significance of those links was limited and no benefits were found for women.

      The researchers also found no consistent pattern of harm with multivitamin use. But they did find several studies linking specific supplements to certain ailments. For example, beta-carotene supplements may boost the risk of lung cancer and death among high-risk populations, such as smokers.

      Multivitamins Don’t Prevent Cognitive Decline in Men

      Multivitamins typically contain several nutrients believed to promote cognitive health—such as vitamins B, C, and E. However, downing a daily multivitamin may do little to keep your mind sharp, warn scientists from the Physicians Health Study II, also included in the new issue of AOIM..

      The researchers assigned nearly 6,000 participants over the age of 64 to a daily multivitamin or placebo regimen. Over twelve years, they assessed changes in participants’ cognitive function and found no significant differences between multivitamin and placebo users. The researchers conclude that daily multivitamin use provides no benefit for preventing cognitive decline.

      High-Dose Multivitamins Won’t Stop Heart Problems

      Daily multivitamins may also fall short of the mark for protecting patients with a history of heart attack.

      In another study published in AOIM, researchers assigned over 1,700 men and women to a high-dose multivitamin or placebo regimen. All of the participants had experienced a heart attack at least six weeks before the start of the study.

      After an average follow-up of 4.6 years, the researchers found no difference in the rate of recurrent cardiovascular events among participants who took supplements compared to those who did not. Multivitamins did not appear to be harmful; however, the supplements also did not seem to offer any protection against ongoing heart problems.

      Supplements Do Provide Benefits in Certain Situations

      For most people, eating a variety of healthy foods is all it takes to meet their nutritional needs. Plus, according to the Mayo Clinic, whole foods provide benefits that pills don’t offer – such as dietary fiber, protective phytochemicals, and micronutrients.

      However, research shows that some people do benefit from certain supplements. For example:


      • Women who may become pregnant should take 400 micrograms of folic acid daily to prevent spina bifida and other birth defects, advises the Centers for Disease Control and Prevention. Those who take folic acid in early pregnancy may also lower the risk of delivering a child with autism, according to new research published in the Journal of the American Medical Association.
      • Women who are pregnant may also benefit from iron supplementation to protect against anemia. Prenatal iron supplements may also reduce the risk of low birth rates, advises a recent review of over 90 studies.
      • Vegetarians and vegans who avoid meat, eggs, and dairy should eat foods fortified with B12 or take supplements, counsels the Harvard Health Letter. People over the age of 50 are also at risk of vitamin B12 deficiency, which may impact balance, memory, and possibly mood.

      Before you stock up on multivitamins or other supplements, exercise some extra caution: take the time to ask your doctor if they are right for you.

      I hate studies. They are so inconclusive. One day they save you an the next they cause Cancer. My pop lived to be 80 and he only took Vitamin E. Not sure why Vit E but that was it.
      Prescription wise he would only take High BP meds.


      That being said....I cant see how vitamins could be bad for you. I take Magesium b/c it supposedly helps with muscles and nervous system.
      *Commitment to Excellence* Excellence is our goal here at BOP. There is a saying that goes like this....if you dont have any haters then you arent doing something right! Haters love success so lets blow the top off of the Bodybuilding internet world!"

      I use the GNC Mega Men all the time and feel it helps keep me from catching a cold too often . Vitamins are supposed to boost immunity and doctors are so close minded regarding this and dietary supplements , exercise , even steroids . you would think they'd be more hip in the world we live in .

      These studies are not facts just opinions. Each person is made differently. Unless they test every person in the world it's inconclusive.

      I guess we will slowly see the supplement business dissolve as future generations are fed the idea that supplements are as useless as witch hazel.

      As sure as I'm writing this there will be some sort of study released from "supplement industry " stating how beneficial sups can be . Follow the money!! Pharmaceutical co's have to be thrilled with this study.
