It seems more that Curcumin that isn't passed into the kidneys can pass the blood-brain barrier[0], and you can help prevent that by taking it with piperine; most formulations, at least on Amazon, have piperine in it, if it doesn't take it with some black peppercorns. It appears the only difference between most formulations and Longvida is that they pair it with coconut oil? That's what I could gather from their formulation, they don't even list piperine.

I'm skeptical of the brand in particular, not in the sense that it's bio-available, but their claim that only their brand crosses the blood-brain barrier[1][2].

[0] a lot of sites mention this in passing, but here's a study that shows 7 days of supplementation crosses the blood-brain barrier, at least in mice: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2781139/
