So that range of about 400 to about 600 milligrams per day seems to be the minimum threshold for getting a cognitive effect in these elderly patients. In that case, they were patients. A good review about the anthocyanins potentially contributing to offsetting cognitive decline in things like Alzheimer's, and also enhancing brain function in people that don't have Alzheimer's, is a review by Afzal, A-F-Z-A-L, that was published in 2019. We will also provide a link to that study in the caption. When one looks across the total batch of studies that are out there on this, it appears, that if one is going to supplement with blueberry extract to get the anthocyanin effect on cognition, dosages of somewhere between 5 1/2 or about 11 grams seem optimal with the higher end, closer to 10 or 11 grams being more beneficial.
