Regulation of Dietary Supplements Dietary supplements are not subject to the same standards as prescription or over­the­ counter drugs Manufacturers do not have to prove their products are safe or effective before they put them on the market FDA can pull supplements proven to be dangerous, but only after the fact; it is up to the FDA to make its case Regulation of Dietary Supplements: Medwatch The FDA’s Medwatch system can be used to report possible adverse reactions to dietary supplements http://www.fda.gov/medwatch/report/hcp.htm Examples of FDA Warnings January, 2004: FDA warns consumers not to feed their babies “Better than Formula Ultra Infant Immune Booster 117" being sold over the internet as a dietary supplement February, 2002: Consumers warned to stop using the products PC SPES and SPES capsules because they contain undeclared prescription drug ingredients that could cause serious health effects Examples of FDA Warnings November, 2001: consumers warned to immediately stop use of LipoKinetix, a weight loss product; implicated in a number of serious liver injuries.

Cautions Regarding Dietary Supplements There may be a discrepancy between the ingredients on the label and what’s inside This is especially true of herb mixtures, such as Chinese herbs The dosage of the “active ingredient” in herbals can vary widely depending on the variety of plant, where it’s grown, climate, etc. Read the Dietary Supplement Label and Verify…. Complete botanical name of the product (make sure it is the right botanical) The part of the plant used to make the product; it should be the part that contains the active components The concentration of the botanical and if it is appropriate, neither too weak or two strong Debusk, RM. A practical guide to herbal supplements for nutrition practitioners. Top Clin Nutr 16:53, 2001 Read the Dietary Supplement Label and Verify…. The daily dosage needed to obtain the desired effect The list of ingredients used to identify fillers, potential allergens Lot number Expiration date Recognized seal of approval (Good Housekeeping, USP, Consumerlab) Compare prices: prices vary widely Debusk, RM. A practical guide to herbal supplements for nutrition practitioners.

Buy from large, trusted retailers, not unknown sellers on the Internet. Look on the bottle for a stamp from USP, NSF or ConsumerLab.com. While the stamp doesn't guarantee the product is safe and effective, it does indicate that the manufacturer has submitted the product for testing to show that it contains what is stated on the label. Don’t spend a fortune on vitamins. Pricey products toting all sorts of "extras" aren't necessary and may be trouble.
