Not according to ConsumerLab.com, an online consumer
watchdog company that has undertaken quality testing of
some of the more popular dietary supplements. Late last
year, the company released the first of its findings: of 30
ginkgo biloba brands analyzed, seven — or roughly 25% — did
not contain sufficient levels of the chemicals known to
give the herb its healing powers.

select a supplement that lives up to its http://www.consumerlab.com label. Before
choosing a brand, call the manufacturer and ask for
information showing specifically what a given supplement
contains and in what amount "Companies should be able to
provide documentation from independent laboratories," says
Firshein. "If they can't or won't . . . then I would choose
