Travis MacKenzie, MD | Men's Health

About this channel
I'm Dr. Travis MacKenzie — board-certified emergency physician, masters bodybuilder, and a guy in his late forties still figuring out how to train hard without breaking. This channel covers training after 40, reading your own labs, the actual data behind supplements, and what two decades in an emergency department teaches you about staying healthy. No hype, no miracle protocols, and I'll tell you when the evidence is thin.

Next stop: Masters Nationals, November 2026.
