Suggestive paper, but I am not holding my breath waiting for human studies. What oral dose would give a serum concentration similar to the in vitro concentration seen in the slices of rat brain?
Great question, for which, unfortunately I have know definitive answer. I do recall reading that ~40 strawberries yielded ~75 mg of fisetin, the amount of pure fisetin used in one of the studies.
I'm considering stacking several of the compounds (resveratrol, leutolin, pterostilbene, fiseten etc...) listed in your intriguing post
