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.

You must be a ConsumerLab.com member to get the full test results along with ConsumerLab.com's Top Picks and ConsumerTips on how to choose and use ginkgo supplements.
