Internet source: "Not all bilberry supplements contain authentic bilberry. ... the availability of less expensive, non-authentic ingredients, particularly from China . . . ."

It appears that supplement makers that get their bilberry extract from Indena, S.p.A., Milan, Italy get real and standardized bilberry extract. As best I can figure.

If the bilberry extract comes from Red China who knows what the hell it is.
