Optimal dosages of blueberries?

Andrew Huberman discusses the cognitive benefits of consuming blueberries, specifically highlighting their anthocyanins. Based on studies, if one chooses to supplement with blueberry extract to harness the anthocyanin effect on cognition, dosages of about 5.5 to 11 grams seem optimal, with the higher end of this range being more beneficial. For those who prefer to consume fresh blueberries, 60 to 120 grams daily is recommended to sufficiently obtain the cognitive effects of anthocyanins 1 .
