NIH Key Points
-
Dietary supplements contain a variety of ingredients, such as vitamins, minerals, amino acids, and
herbs or other botanicals. Research has confirmed health benefits of some dietary supplements but
not others.
-
To use dietary supplements safely, read and follow the label instructions, and recognize that “natural”
does not always mean “safe.” Be aware that an herbal supplement may contain dozens of compounds
and that all of its ingredients may not be known.
-
Some dietary supplements may interact with medications or pose risks if you have medical problems
or are going to have surgery. Most dietary supplements have not been tested in pregnant women,
nursing mothers, or children.
-
The U.S. Food and Drug Administration (FDA) regulates dietary supplements, but the regulations for
dietary supplements are different and less strict than those for prescription or over-the-counter
drugs.
-
Tell all your health care providers about any complementary health approaches you use. Give them a
full picture of what you do to manage your health. This will help ensure coordinated and safe care.
