Tips for Dietary Supplement Users
On This Page
Even if you eat a wide variety of foods, how can you be sure that you are getting all the vitamins, minerals, and other nutrients you need as you get older? If you are over 50, your nutritional needs may change. Informed food choices are the first place to start, making sure you get a variety of foods while watching your calorie intake. Supplements and fortified foods may also help you get appropriate amounts of nutrients. To help you make informed decisions, talk to your doctor and/or registered dietitian. They can work together with you to determine if your intake of a specific nutrient might be too low or too high and then decide how you can achieve a balance between the foods and nutrients you personally need.
Today's dietary supplements are not only vitamins and minerals. They also include other less-familiar substances, such as herbals, botanicals, amino acids, enzymes, and animal extracts. Some dietary supplements are well understood and established, but others need further study. Whatever your choice, supplements should not replace the variety of foods important to a healthful diet.
Unlike drugs, dietary supplements are not pre-approved by the government for safety or effectiveness before marketing. Also, unlike drugs, supplements are not intended to treat, diagnose, prevent, or cure diseases. But some supplements can help assure that you get an adequate dietary intake of essential nutrients; others may help you reduce your risk of disease. Some older people, for example, are tired due to low iron levels. In that case, their doctor may recommend an iron supplement.
At times, it can be confusing to tell the difference between a dietary supplement, a food, or over-the-counter (OTC) medicines. This is because supplements, by law, come in a variety of forms that resemble these products, such as tablets, capsules, powders, energy bars, or drinks. One way to know if a product is a dietary supplement is to look for the Supplement Facts label on the product.
While certain products may be helpful to some older individuals, there may be circumstances when these products may not benefit your health or when they may create unexpected risks. Many supplements contain active ingredients that have strong biological effects in the body. This could make them unsafe in some situations and hurt or complicate your health. For example:
Remember: Your combined intake from all supplements (including multivitamins, single supplements, and combination products) plus fortified foods, like some cereals and drinks, could cause health problems.
You and your health professionals (doctors, nurses, registered dietitians, pharmacists, and other caregivers) are a team working toward a common goal -- to develop a personalized health plan for you. Your doctor and other members of the health team can help monitor your medical condition and overall health, especially if any problems develop. Although they may not immediately have answers to your questions, these health professionals have access to the most current research on dietary supplements.
There are numerous resources that provide information about dietary supplements. These include TV, radio, newspapers, magazines, store clerks, friends, family, or the Internet. It is important to question recommendations from people who have no formal training in nutrition, botanicals, or medicine. While some of these sources, like the Web, may seem to offer a wealth of accurate information, these same sources may contain misinformation that may not be obvious. Given the abundance and conflicting nature of information now available about supplements, it is more important than ever to partner with your healthcare team to sort the reliable information from the questionable.

Be savvy! Although the benefits of some dietary supplements have been documented, the claims of others may be unproven. If something sounds too good to be true, it usually is. Here are some signs of a false claim:
Statements that the product is a quick and effective "cure-all." For example: "Extremely beneficial in treatment of rheumatism, arthritis, infections, prostate problems, ulcers, cancer, heart trouble, hardening of the arteries, and more."
Statements that suggest the product can treat or cure diseases. For example: "shrinks tumors" or "cures impotency." Actually, these are drug claims and should not be made for dietary supplements.
Statements that claim the product is "totally safe," "all natural," or has "definitely no side effects."
Promotions that use words like "scientific breakthrough," "miraculous cure," "exclusive product," "secret ingredient," or "ancient remedy." For example: "A scientific breakthrough formulated by using proven principles of natural health-based medical science."
Text that uses overly impressive-sounding terms, like those for a weight-loss product: "hunger stimulation point" and "thermogenesis."
Personal testimonials by consumers or doctors claiming amazing results. For example: "My husband has Alzheimer's. He began eating a teaspoonful of this product each day. And now in just 22 days, he mowed the grass, cleaned out the garage, and weeded the flower beds; we take our morning walk together again."
Limited availability and advance payment required. For example: "Hurry. This offer will not last. Send us a check now to reserve your supply."
Promises of no-risk "money-back guarantees." For example: "If after 30 days you have not lost at least 4 pounds each week, your uncashed check will be returned to you."
Unlike prescription and over-the-counter medicines, dietary supplement products are not reviewed by the government before they are marketed. Under the law, manufacturers of dietary supplements are responsible for making sure their products are safe before they go to market. If you want to know more about the product you are purchasing, check with the manufacturer to find out if the firm:
FDA has the responsibility to take action against unsafe dietary supplement products after they reach the market. The agency may also take legal action against dietary supplement manufacturers if FDA can prove that claims on marketed dietary supplements are false and misleading.
Adverse effects from the use of dietary supplements should be reported to the FDA's MedWatch Program. You, your healthcare provider, or anyone should report a serious adverse event or illness directly to FDA if you believe it is related to the use of any dietary supplement product by calling FDA at: 1-800-FDA-1088, by fax at: 1-800-FDA-0178 or reporting on-line. FDA would like to know whenever you think a product caused you a serious problem, even if you are not sure that the product was the cause, and even if you do not visit a doctor or clinic.
Ask yourself the following questions and use the checklist below to talk to your doctor, nurse, dietitian, pharmacist, and/or caregiver about dietary supplements.
Because many products are marketed as dietary supplements, it is important to remember that supplements include botanical/herbal as well as vitamin/mineral products. The list* below gives some examples of products you may see sold as dietary supplements. It is not possible to list them all here. Note: the examples provided do not represent either an endorsement or approval by FDA or any coalition members.

If you take dietary supplements, you may find it helpful to complete the chart below and share it with your healthcare team, who could include your doctor, nurse, registered dietitian, pharmacist, and/or caregiver. All of these professionals need this information to help develop a personalized plan for you.
To have as accurate a record as possible, list the supplements you take and how often. By supplements we mean multiple, single or combination vitamins, minerals (like calcium and iron), or any herbal or botanical supplement you may have on your kitchen or medicine cabinet shelf. Because supplements come in so many forms that resemble other food and drug products, check to see if there is a Supplement Facts label on the product to be certain it is a dietary supplement.
Complete, to the best of your ability, amounts and reasons for taking supplements on the chart below. Then, give this information to your healthcare team so you can discuss what are the best decisions for your overall health.
