I emailed Teresa Cody and asked her about this, because saying something along those lines is very misleading. This is her response, which I thought was beneficial to share,
No, I did not say that. I said that Longvida combined curcumin with Phosphatidylcholine and that is what gets it across the BBB. I read it on their site a few years ago. Now instead of telling you what is in it, they say it is a proprietary mixture, or something like that. I was just telling everyone that they needed PC combined with the curcumin to make it work, so just taking curcumin by itself won't do the same thing. I use Longvida myself. I wasn't telling them not to use it. I'm not sure where they got that.Longvida's site does explain the mechanism how LC works. But, I thought it would also be good to share just a little more information regarding this, in case others believe they may get the same result with just giving any Curcumin and PC.
A mom to a little girl with DS, Liora P., asked Verdue Sciences about this concern and the response is below. I have also linked to the PDF study which was sent that shows what is answered. .
Longvida is not a simple mixture of curcumin and phospholipids Longvida is made with a patent-pending technology (Solid-Lipid Curcumin Particle or SLCP) that is a precise complex which includes phospholipids and other lipids and factors that are critical to its bioavailability and activity.Link to study: http://www.gotdownsyndrome.net/LCvsCurcuminPC.pdf
During development of Longvida a curcumin-phospholipid mixture was tested and it was not much of an improvement. In fact, commercial versions of simple curcumin-phospholipid mixtures do not result in any free curcumin in blood, only the inactivated curcumin glucuronide which does not pass the BBB. Attached is a study which shows that.
I hope this will clear up any confusion anyone might have.
