What does it take to fuel the most elite light infantry unit in the U.S. Army — and earn their respect doing it? Dr. Nick Barringer didn't just study performance nutrition, he built the standard for it inside the 75th Ranger Regiment.

Dr. Nick Barringer is a retired Army Lieutenant Colonel, Bronze Star and Legion of Merit recipient, Ranger-tabbed, airborne-qualified combat veteran, and one of the foremost authorities on tactical performance nutrition in the United States. He holds a PhD in Kinesiology from Texas A&M, co-authored the International Society of Sports Nutrition's position stand on Tactical Athlete Nutrition, and spent years embedded with the 75th Ranger Regiment as part of the Ranger Athlete Warrior (RAW) Program — one of the first human performance programs in all of Special Operations. He later served as Program Director for the Army Baylor Graduate Program in Nutrition and as an Assistant Professor at West Point. Most recently, he founded Salvo Gum, a precision-dosed performance caffeinated gum engineered for controlled alertness under pressure.
In this conversation, you'll hear:

Whether you're a tactical athlete, a serious lifter, a first responder, or someone who simply wants to perform at a higher level — this episode will change how you think about fueling your body and protecting your mind.
