In an ideal world, no one would need dietary supplements. Our balanced diets would provide all the vitamins, minerals and other nutrients our bodies need. Alas, the world of American eating is far from ideal. And that, some nutrition experts and supplement advocates argue, is why we need dietary supplements. The latest federal data show that more than half of U.S. adults use dietary supplements, mostly multivitamins.
When you reach for that bottle of vitamin C or fish oil pills, you might wonder how well theyâll work and if theyâre safe. The first thing to ask yourself is whether you need them in the first place. More than half of all Americans take one or more dietary supplements daily or on occasion.Supplements are available without a prescription and usually come in pill, powder or liquid form. Common supplements include vitamins, minerals and herbal products, also known as botanicals.People take these supplements to make sure they get enough essential nutrients and to maintain or improve their health.ut not everyone needs to take supplements. âItâs possible to get all of the nutrients you need by eating a variety of healthy foods, so you donât have to take one,â says Carol Haggans, a registered dietitian and consultant to NIH. âBut supplements can be useful for filling in gaps in your diet.â.
