Why Iron Fox Exists.
Iron Fox was born from experience.In June 2024, while training for the Midnight Sun Marathon in Tromsø, Norway, I began to feel the impact of my cycle in a way I could no longer ignore.Energy fluctuated. Performance dropped.
My body stopped responding the way it should.I was later diagnosed with amenorrhea, a condition widely recognised in sports science and closely linked to Relative Energy Deficiency in Sport (RED-S).After recovering and returning to training, I started looking at how I could better support my body through sports nutrition.I assumed there would already be products and education built specifically for female athletes. Designed to support how women actually train, recover and perform.There wasn’t.
What I found instead was an industry where products have been designed around male physiology and formulated using male-focused research.So I built what didn’t exist.
IRON FOX.
