Yes, because lasix stops microscopic EIPH bleeding deep in the lungs and thus the horse gets more oxygen.

But it doesn't improve performance in non bleeders. It just lets them "regain their performance level."

No, that's not what I said. I said horses that suffer EIPH will regain their performance levels because they are no longer bleeding.

If you give lasix (which is simply a loop diuretic) to a horse that does not experience EIPH due to it's work (such as an elite-level cutting horse, a barrel racer), no, lasix will not improve it's performance.

Lasix is not a stand-alone performance enhancer.

Lasix is a therapeutic medication that attenuates EIPH. Of course, if you eliminate bleeding into a horses lungs, the horse will get more oxygen and perform better.
