Definitely liposomal, though it is expensive.
As Mary said, watch out for the Dr Mercola, though. I bought some because it was so much cheaper, but I have my doubts about whether it's really what it claims to be. It's in capsule form. I broke one open and, uck, the stickiest mess ever. And stains your fingers with all the colouring they put in there. I tried stirring the contents of the capsule into a glass of water, as I've done with real, more expensive liposomal, but it just remained as a disgusting sludge at the bottom of the glass. Avoid.
