They also play important roles in bodily functions such as metabolism, immunity and digestion. According to the U. National Library of Medicine, the best way to meet your vitamin needs is to eat a balanced diet containing a variety of foods. If you can't meet your needs through food alone, you may require dietary supplements.
What You Need to Know The majority of adults in the United States take one or more dietary supplements either every day or occasionally. Dietary supplements come in a variety of forms: Popular supplements include vitamins D and E; minerals like calcium and iron; herbs such as echinacea and garlic; and specialty products like glucosamine, probiotics, and fish oils.
The Dietary Supplement Label All products labeled as a dietary supplement carry a Supplement Facts panel that lists the contents, amount of active ingredients per serving, and other added ingredients like fillers, binders, and flavorings. The manufacturer suggests the serving size, but you or your health care provider might decide that a different amount is more appropriate for you.
Scientific evidence shows that some dietary supplements are beneficial for overall health and for managing some health conditions. For example, calcium and vitamin D are important for keeping bones strong and reducing bone loss; folic acid decreases the risk of certain birth defects; and omega-3 fatty acids from fish oils might help some people with heart disease.
Other supplements need more study to determine their value. Food and Drug Administration FDA does not determine whether dietary supplements are effective before they are marketed. Safety and Risk Many supplements contain active ingredients that can have strong effects in the body. Always be alert to the possibility of unexpected side effects, especially when taking a new product.
Supplements are most likely to cause side effects or harm when people take them instead of prescribed medicines or when people take many supplements in combination.
Dietary supplements can also interact with certain prescription drugs in ways that might cause problems. Here are just a few examples: Antioxidant supplements, like vitamins C and E, might reduce the effectiveness of some types of cancer chemotherapy.
Keep in mind that some ingredients found in dietary supplements are added to a growing number of foods, including breakfast cereals and beverages. As a result, you may be getting more of these ingredients than you think, and more might not be better.
Taking more than you need is always more expensive and can also raise your risk of experiencing side effects. For example, getting too much vitamin A can cause headaches and liver damage, reduce bone strength, and cause birth defects.
Excess iron causes nausea and vomiting and may damage the liver and other organs.
Be cautious about taking dietary supplements if you are pregnant or nursing. Most dietary supplements have not been well tested for safety in pregnant women, nursing mothers, or children. If you suspect that you have had a serious reaction from a dietary supplement, let your health care provider know.
He or she may report your experience to the FDA. In addition, report your reaction to the dietary supplement company by using the contact information on the product label.
Quality Dietary supplements are complex products. The FDA has established good manufacturing practices GMPs for dietary supplements to help ensure their identity, purity, strength, and composition. These GMPs are designed to prevent the inclusion of the wrong ingredient, the addition of too much or too little of an ingredient, the possibility of contamination, and the improper packaging and labeling of a product.
The FDA periodically inspects facilities that manufacture dietary supplements. In addition, several independent organizations offer quality testing and allow products that pass these tests to display their seals of approval.
These seals of approval provide assurance that the product was properly manufactured, contains the ingredients listed on the label, and does not contain harmful levels of contaminants.
These seals of approval do not guarantee that a product is safe or effective. Organizations that offer this quality testing include: Check with your health care provider about the supplements you take if you are scheduled to have any type of surgical procedure.Why Are Supplements Important?
