To the best of my knowledge there is only one patented maker of Stabilized R-lipoic acid... Geronova. I would think they supply the various supplement makers the raw material. So there is going to be the same thing inside each capsule.
LEF tends to "sell" more aggressively, and charge more.
It is your choice.
