1. Vitor Belfort
Vitor Belfort, and all of his supplements, have knocked out more opponents in the UFC than anyone else. 12 of Belfort’s 18 career knockouts have come in the UFC, that’s just 1 more than 2nd place Anderson Silva.
Belfort has knocked out more big names than anybody: Dan Henderson, Michael Bisping, Luke Rockhold, Wanderlei Silva, Rich Franklin, Matt Lindland, and what the heck we’ll even mention that he knocked out Tank Abbott.
How much Belfort’s supplement regimen aided in his striking power is something only he and his sketchy doctors know for sure, but there can be no doubt that his ability to knock out tough-chinned fighters is arguably the best in history.
