So, given the substantial positive literature out there, I decided to try Source Naturals brand Turmeric with Meriva®. 500mg of curcumin bound to phosphatidylcholine to improve its bioavailability, taken twice daily.
Results: Nothing.
Mind you, I did not try any standardized tests to see if my performance in verbal fluency, recall, or anything else changed. I also didn't bind myself. And I have an idiosyncratic response to pretty much everything. Still, for what it's worth, I noticed no positive or negative changes whatsoever.
