A science-backed performance thermoregulation product designed to help athletes manage heat stress and perform more consistently in hot conditions.
truefuels has unveiled CoreCtrl, a first-of-its-kind performance nutrition product that creates an entirely new category: performance thermoregulation.
Rather than focusing solely on hydration or electrolytes, CoreCtrl addresses a deeper limiter of performance—how the body handles heat under load. With 75–80% of exercise energy released as heat, overheating often becomes the real bottleneck. CoreCtrl is built to change that.
Most sports nutrition replaces what you lose. CoreCtrl helps you control what limits you.
Backed by current sports science and informed by recent research (Peel et al., 2024), CoreCtrl is designed to:
The result: greater consistency, resilience, and recovery when training or racing in the heat.
CoreCtrl doesn’t artificially cool the body or override physiology. Instead, it works alongside hydration and fueling, supporting the body’s natural thermoregulation systems—enhancing cooling efficiency while maintaining cardiovascular stability under heat stress.
This makes it a natural complement to truefuels’ existing 40g Gels and Electrolytes, which replace energy and fluids, while CoreCtrl supports the system that determines how effectively the body can dissipate heat.
CoreCtrl was developed and field-tested by real athletes, including Alistair Brownlee—two-time Olympic triathlon champion and co-founder of truefuels—whose career has been shaped by racing in extreme heat.
“It’s not about overriding the body’s responses, but enhancing resilience and giving athletes an edge when the heat is on.”
— Alistair Brownlee, Co-Founder, truefuels
CEO and Co-Founder Goran Vasiljevic adds that CoreCtrl represents a shift from replacement to control, helping athletes train and perform in heat rather than being limited by it.
Athletes are advised to take one serving daily for eight days leading into a hot race or heat-focused training block, mixed with 500 ml of cold water and consumed 30–60 minutes before exercise. As always, test in training before race day.
Heat is one of the most underestimated performance limiters in sport. With CoreCtrl, truefuels isn’t just adding another supplement—it’s introducing a new performance lever.
Fuel replaces. Hydration sustains.
Thermoregulation controls the outcome.
CoreCtrl is built for athletes who want to stay composed, powerful, and consistent—when conditions are at their toughest.
