In this episode, I share a fascinating 1950s endurance experiment with rats that uncovered what researchers called an “anti-fatigue factor” in beef liver.

The results highlight why organ meats like liver are nature’s ultimate multivitamin and how even small micronutrient deficiencies can wreck ATP energy production, mitochondrial health, and overall performance. I’ll walk you through what the study revealed, how it ties into modern fatigue and performance issues, and why I believe high-quality liver supplements are one of the simplest ways to cover nutritional gaps. If you’ve ever wondered about beef liver benefits or why organ meats nutrition matters, this story will change how you think about natural energy.
