About Fit4Duty Supplements

Fit4Duty Supplements is a first responder–owned company founded on the principles of service to God, country, and community.

The company was founded by Derrick Gaither, who has dedicated the last 16 years to Emergency Medicine and is currently serving as a Flight Paramedic. Through years of frontline experience, Derrick understands firsthand the physical and mental demands placed on those who serve. Long shifts, high-stress environments, and life-or-death decisions require peak performance every single time.

That experience is the foundation of Fit4Duty Supplements.

Our mission is simple:

“Supporting those who serve with quality supplements to assist them in staying fit for duty.”

We believe maintaining peak physical readiness is not optional, it’s essential. When lives depend on you, being fit for duty matters.
