“Danny Lennon has been killing it for YEARS with the Sigma Nutrition podcast. He, and his team, share so much high quality, evidence-based advice.

As a repeat guest on the show, I’ve always appreciated Danny’s preparedness and curiosity.

And, back when I ran Precision Nutrition, it was a staple listen for many of our team members.”
