Pharmacists Pelton and LaValle state at the outset that "until now, there have been almost no easily accessible resources available that tell us about the interactions between prescription drugs and nutrients." They set out to meet this need, which seems like a good idea, since 70 percent of households are reported to use vitamin and mineral supplements. The authors offer consumers solid information on classes of drugs and the nutrients they might deplete. They provide basic explanations of essential nutrients and their sources, along with a list of drugs that may cause their loss. The book affords so much practical and useful data that one wishes it were better arranged. Most people will search for a drug alphabetically, not by type or class, and turning to both the general and the brand-name indexes is inconvenient. A more serious drawback is that although the authors say they have obtained their information from a database that they maintain, no references to studies are given. Instead, readers are referred to the publisher's web site. Despite these drawbacks, the book provides clear information in a neglected area and is recommended for all consumer health collections. It is hoped the next edition will include references.--Natalie Kupferberg, Ohio State Univ., Columbus Copyright 2000 Cahners Business Information.
