mass media outlets have for the past 5 years gradually
reinforced that doubt through reports suggesting that many
dietary supplements do not actually contain the ingredients
or the ingredient quantities listed on the their labels.
These reports, while well intentioned, sometimes create
confusion among consumers about which manufacturers are
credible and which products are suitable for use. The need
here is for a comprehensive volume on all of the products
available in the marketplace.
of Analytical Methods for Dietary Supplements is a 215
page library published by the American Pharmacists Association.
It contains an extensive set of product monographs, details
of sampling of methods along with appropriate validation
data, if known, about the most common supplements in
the market place today.
book is comprehensive enough in its first edition to
also include 85 analytical monographs. Each monograph
follows a standard format for quick reference which includes:
of the product’s purpose or use
of action (if known)
compounds that are commonly assayed
of variation in species when there are several species
ingredients also include the botanical name, the common
name, the part of the plant used and its uses
are the methods of analysis, reference standards and/or
marker compounds used as well as validation data, (if
available), are included as well as the references.
book is not intended to give a comprehensive overview
for all dietary supplements, however, it is a very useful
reference for analytical and medicinal chemists, research
and development scientists, quality control personnel,
pharmacognosists, academicians and students. It stands
as a solid resource of reference standards for vitamins,
dietary supplements, and botanicals.
book is a state of the art compilation that provides
current methods and validation data and is a greatly
needed addition to improving the overall quality of testing
standards for dietary supplements in laboratories around
supplement potency, efficacy and purity are all factors
that professional and non-professional practitioners
alike have traditionally often gleaned through trial & error
with various brands. The dietary supplement industry
is surely facing serious legislative controls in a variety
of marketplaces unless it starts to govern itself through
reliably consistent, self-imposed standards embraced
by the entire industry. NSF International, U.S. Pharmacopeia
and many other organizations are working hard to develop
reliable standards which can be embraced by a responsible
dietary supplement industry. Despite repeated U.S. congressional
defeats of various dietary supplement industry regulatory
bills in recent years, there are enough concerned scientists
out there to put together a publication of this nature.
I highly recommend this book to any lab that provides
testing for dietary supplement manufacturing and to any
dietary supplement manufacturer that is interested in
implementing best practices.
