Regarding anthocyanin concentration, how much more potent are European bilberries compared to American blueberries?

Answer

Up to four times more anthocyanins

The primary metric determining the nutritional superiority of the bilberry is its concentration of anthocyanins, the flavonoid pigments responsible for their deep coloring and antioxidant properties. Multiple comparisons indicate that European bilberries are significantly richer sources of these compounds, frequently reported to contain concentrations that are up to four times higher than those found in cultivated American blueberries. This high load of anthocyanins is the underlying reason why bilberries are often cited as having superior antioxidant potency and why they provide a stronger flavor impact. This substantial difference in phytochemical density is a key factor when prioritizing targeted health benefits, especially those related to visual support.
