We believe every person has a fighter within

Whether you're battling in the ring, pushing your limits in the gym, or conquering life's daily challenges, we're here to fuel your fight.

Our Story

Born in the heart of Thailand's Muay Thai scene, Rex Nutrition was founded on a simple yet powerful observation: elite fighters deserved better fuel. Our founder, Mona Röhr, saw firsthand the sacrifice and endurance required to perform at the highest level. She also saw the inadequate supplements these warriors relied on.

That's when Rex Nutrition was born – a call to action for those who refuse to compromise.

The Rex Difference

Our premium formula isn't just about hydration; it's about powering your performance to new heights. We've combined all five essential electrolytes – sodium, magnesium, potassium, calcium, and phosphorus – with added vitamins D, C, and iron. The result? Real, relentless hydration and strength that fuels your body and mind.
