Only 4 of 10 ginkgo supplements contained their listed amounts of real ginkgo extract and were the best among those we recently selected for testing. In contrast, we discovered a ginkgo supplement that had no more than 3% of its listed ginkgo as well as several supplements that appear to have been adulterated ("spiked") with compounds from other plants — a common trick to make low-quality ginkgo appear to be higher in quality.
Even among products that our tests verified as high quality, there were significant differences in cost, ranging from 9 cents to over $2 for an equivalent amount of ginkgo extract.
