Study Finds No Benefit for Dietary Supplements

More than half of U. S. adults take アプソルシン supplements [1]. I don’t, but some of my family members do. But truly does popping all of these vitamins, minerals, and other substances really end up in a longer, healthier life? A new nationwide study suggests it all doesn’t.

Based on an analysis of survey data got from more than 27, 000 people over a six-year span, the NIH-funded study found that individuals who reported consuming dietary supplements had about the same risk of dying as those who have their nutrients through food. What’s more, the mortality health benefits associated with adequate intake of vitamin A, vitamin K, magnesium, zinc, and copper were limited to food consumption.

The study, written and published in the Annals of Internal Medicine, also uncovered certain evidence suggesting that certain supplements might even be harmful to overall health when taken in excess [2]. For instance, people who went on more than 1, 000 milligrams of supplemental calcium everyday were more likely to die of cancer than those who didn’t.

The researchers, led by Fang Fang Zhang, Tufts University, Boston, were intrigued that so many people take overall health supplements, despite questions about their health benefits. While the overall evidence acquired suggested no benefits or harms, results of a limited wide variety of studies had suggested that high doses of a number of supplements could be harmful in some cases.

To take a broader glance, Zhang’s team took advantage of survey data from many U. S. adults, age 20 or older, who had participated in six annual cycles of the National Into the Nutrition Examination Survey (NHANES) between 1999-2000 and 2009-2010. NHANES participants were asked whether they’d used every dietary supplements in the previous 30 days. Those who answered yes were then simply asked to provide further details on the specific product(s) and how rather long and often they’d taken them.

Just over half of participants claimed use of dietary supplements in the previous 30 days. Nearly 40 percent revealed use of multivitamins containing three or more vitamins.

Nutrient eating from foods was also assessed. Each year, the study’s participants were asked to recall what they’d had over the last 24 hours. The researchers then used that tips to calculate participants’ nutrient intake from food. The ones calculations indicated that more than half of the study’s participants have inadequate intake of vitamins D, E, and K, and even choline and potassium.

Over the course of the study, more than 3, one thousand of the study’s participants died. Those deaths included 945 attributed to cardiovascular disease and 805 attributed to cancer. The next step was to look for any association between the nutrient intake and the fatality data.

The researchers found the use of dietary supplements had certainly no influence on mortality. People with adequate intake of vitamin A good, vitamin K, magnesium, zinc, and copper were less likely to die. However , that relationship only held to get nutrient intake from food consumption.

People who reported acquiring more than 1, 000 milligrams of calcium per day was more likely to die of cancer. There was also evidence that men who took supplemental vitamin D at a dose outperforming 10 micrograms (400 IU) per day without a vitamin Debbie deficiency were more likely to die from cancer.

It’s worthwhile noting that the researchers did initially see an association relating to the use of dietary supplements and a lower risk of death due to virtually all causes. However , those associations vanished when they accounted pertaining to other potentially confounding factors.

For example , study participants who seem to reported taking dietary supplements generally had a higher level of learning and income. They also tended to enjoy a healthier lifestyle. Some people ate more nutritious food, were less likely to smoking or drink alcohol, and exercised more. So , it appears that folks that take dietary supplements are likely to live a longer and healthier everyday life for reasons that are unrelated to their supplement use.

Although study has some limitations, including the difficulty in distinguishing association right from causation, and a reliance on self-reported data, its collected information suggest that the regular use of dietary supplements should not be recommended for the overall U. S. population. Of course , this doesn’t rule out the possibility that certain subgroups of people, including perhaps those following several special diets or with known nutritional deficiencies, may reap some benefits.
