  6. 6. Federal Regulation of Dietary Supplements <ul><li>Not the same as those for prescription or over the counter drugs-in general they are less strict </li></ul><ul><li>A manufacturer DOES NOT have to prove a product’s safety and effectiveness before it is marketed </li></ul>
  7. 7. Federal Regulation of Dietary Supplements <ul><li>A manufacturer is permitted to say that a supplement addresses: </li></ul><ul><ul><li>supports health </li></ul></ul><ul><ul><li>a nutrient deficiency </li></ul></ul><ul><ul><li>is linked to a particular </li></ul></ul><ul><ul><li>body function (like immunity </li></ul></ul><ul><ul><li>or heart health) </li></ul></ul><ul><ul><li>if there is research to support the claim. </li></ul></ul>
  8. 8. Federal Regulation of Dietary Supplements <ul><li>Claim must be followed by the words </li></ul><ul><li>“ This statement has not been evaluated by the US FDA. This product is not intended to diagnose, treat, cure, prevent any disease”. </li></ul>

  10. 10. Federal Regulation of Dietary Supplements <ul><ul><li>Monitors safety once a dietary supplement is on the market </li></ul></ul><ul><ul><li>If it finds a product to be unsafe, it can take action against the manufacturer and/or distributor. </li></ul></ul><ul><ul><li>Monitors product information, such as label claims and package inserts </li></ul></ul>
  11. 11. Federal Regulation of Dietary Supplements <ul><ul><li>Polices product advertising and requires all information to be truthful and not misleading </li></ul></ul>
  12. 12. Safety Considerations <ul><li>If you are thinking about or using a dietary supplement: </li></ul><ul><ul><li>Tell your health care provider to help ensure coordinated and safe care. </li></ul></ul><ul><ul><li>Some supplements interact with medications, may increase the risk of bleeding or affect the response to anesthesia with surgery. </li></ul></ul><ul><ul><li>For example: </li></ul></ul><ul><ul><li>St. John’s wort can speed the breakdown of many drugs (including birth control pills) and thereby reduce their effectiveness) </li></ul></ul>
  13. 13. Safety Considerations <ul><li>Read the label instructions </li></ul><ul><li>Talk to your health care provider if you have questions, particularly about the best dosage for you to take </li></ul><ul><li>Take only one new supplement at a </li></ul><ul><li>time to determine your body’s </li></ul><ul><li>response </li></ul>
  14. 14. Safety Considerations <ul><li>If you experience any side effects that concern you, STOP taking the dietary supplement and contact your health care provider. </li></ul><ul><li>Report your experience to the FDA’s MedWatch safety information line at http://www.fda.gov/medwatch/report/consumer/consumer.htm or call 1-800-FDA-1088 </li></ul>
  15. 15. Safety Considerations <ul><li>Although many dietary supplements come from natural sources, “natural” does not always mean “safe”. </li></ul><ul><ul><li>For example, the herbs comfrey and kava can cause serious harm to the liver </li></ul></ul>
  16. 16. Safety Considerations Be Aware <ul><li>An herbal supplement may contain dozens of compounds and that its active ingredients may not be known </li></ul><ul><li>Researchers are studying many of these products in an effort to identify active ingredients and understand their effects in the body </li></ul>
  17. 17. Safety Considerations Be Aware <ul><li>What’s on the label may not be what’s in the bottle </li></ul><ul><li>Analyses sometimes find differences between labeled and actual ingredients. For example: </li></ul><ul><ul><li>An herbal supplement may not contain the correct plant species </li></ul></ul>
  18. 18. Safety Considerations Be Aware <ul><ul><li>The amount of the active ingredient may be lower or higher than the label states. </li></ul></ul><ul><ul><li>May be contaminated with other </li></ul></ul><ul><ul><li>herbs, pesticides, or metals, or </li></ul></ul><ul><ul><li>even adulterated with unlabeled </li></ul></ul><ul><ul><li>ingredients such as prescription </li></ul></ul><ul><ul><li>drugs. </li></ul></ul>
  19. 19. Safety Considerations <ul><ul><li>Skip the lure of this myth: “Even if a supplement won’t help me, at least it won’t hurt me” </li></ul></ul><ul><ul><li>High doses, taken long enough or combined with other supplements, can be harmful. </li></ul></ul>
  20. 20. Safety Considerations <ul><ul><li>Look for products labeled with the voluntary USP (U.S. Pharmacopeia) or NF (National Formulary) letters </li></ul></ul><ul><ul><ul><li>Indicates the manufacturer self-reports voluntary standards of quality. </li></ul></ul></ul>
