TruNature Ginkgo Biloba with Vinpocetine, 60mg (250 Softgels)
Product Reviews of TruNature Ginkgo Biloba with Vinpocetine, 60mg (250 Softgels)Product Review: NOT a Standardized Extract
TruNature Ginkgo Biloba does NOT contain the standardized ginkgo extract, as it lacks 6% Terpene Lactones (at least the bottle purchased through Amazon did not list it, but only listed the 24% Ginkgo Flavonglycosides; both together are the standard). And this product contains a relatively higher amount of Vinpocetine than other brands, which is a periwinkle extract that might induce side effects such as reduced immune function and depleted catecholamine levels leading to depression (see wikipedia's Vinpocetine article). TruNature is a Costco product.
