FDA 101: Dietary Supplements | FDA

The law defines dietary supplements in part as products taken by mouth that contain a "dietary ingredient." Dietary ingredients include vitamins, minerals, amino acids, and herbs or botanicals, as well as other substances that can be used to supplement the diet.

Dietary supplements come in many forms, including tablets, capsules, powders, energy bars, and liquids. These products are available in stores throughout the United States, as well as on the Internet. They are labeled as dietary supplements and include among others

People use dietary supplements for a wide assortment of reasons. Some seek to compensate for diets, medical conditions, or eating habits that limit the intake of essential vitamins and nutrients. Other people look to them to boost energy or to get a good night's sleep. Postmenopausal women consider using them to counter a sudden drop in estrogen levels.

The Food and Drug Administration (FDA) suggests that you consult with a health care professional before using any dietary supplement. Many supplements contain ingredients that have strong biological effects, and such products may not be safe in all people.

If you have certain health conditions and take these products, you may be putting yourself at risk. Your health care professional can discuss with you whether it is safe for you to take a particular product and whether the product is appropriate for your needs. Here is some general advice:

You should know the following if you are considering using a dietary supplement.

Many dietary supplements have clean safety histories. For example, millions of Americans responsibly consume multi-vitamins and experience no ill effects.

Some dietary supplements have been shown to be beneficial for certain health conditions. For example, the use of folic acid supplements by women of childbearing age who may become pregnant reduces the risk of some birth defects.

Another example is the crystalline form of vitamin B12, which is beneficial in people over age 50 who often have a reduced ability to absorb naturally occurring vitamin B12. But further study is needed for some other dietary supplements.

Some supplements have had to be recalled because of proven or potential harmful effects. Reasons for these recalls include

In addition, unscrupulous manufacturers have tried to sell bogus products that should not be on the market at all.

Before taking a dietary supplement, make sure that the supplement is safe for you and appropriate for the intended purpose.

Adverse effects with dietary supplements should be reported to FDA as soon as possible. If you experience such an adverse effect, contact or see your health care professional immediately. Both of you are then encouraged to report this problem to FDA. For information on how to do this, go to https://www.fda.gov/food/dietary-supplements/how-report-problem-dietary-supplements.

Adverse effects can also be reported to the product's manufacturer or distributor through the address or phone number listed on the product's label. Dietary supplement firms are required to forward reports they receive about serious adverse effects to FDA within 15 days.
