I have no idea about the differencies on those, I just picked NOW foods brand from iHerb, ones that have nothing extra in them. L-carnitine as 500mg capsules, L-ornithine as powder to get the dose right. They have nothing extra, so I guess that's the way to go. Likely they're mostly just generic ones anyway unless its some kind of mix of something.
