Frequently Asked Questions
Current research (Peel 2024) points to altered neuromuscular control from electrolyte depletion — specifically sodium, potassium and taurine. Lactic acid theory largely replaced.
Yes — Peel (2024) showed 4,000mg taurine reduced exercise-induced cramping in a controlled trial. This is the exact dosage in CoreCtrl sachets.
Sustained sodium/potassium loss over 3+ hours + insufficient electrolyte replacement + neuromuscular fatigue in final 10km. Calf most common site due to sustained eccentric load.
