CoreCtrl introduces a new category in performance nutrition: thermoregulation support. While most strategies focus on replacing fluids and electrolytes, CoreCtrl is designed to support how effectively your body sheds heat in the first place. When training or racing in hot and humid conditions, it is not just hydration that determines performance, but how efficiently your body can manage rising internal temperature.
How to use?
Take 1 serving daily for 8 days before a hot race or heat-focused training block, mixing with 500 ml of cold water 30 to 60 minutes before exercise.

When to use?
Use during preparation for hot races, training camps, summer events, or when increasing heat exposure in your sessions.
Why do I need this?
If heat regularly limits your pace, power, or consistency, supporting thermoregulation can help you stay in control for longer.
Who uses this?
Endurance athletes, triathletes, cyclists, runners, and anyone training or competing in warm or humid conditions.
About CoreCtrl
During exercise, up to 75% to 80% of energy is released as heat. If that heat is not dissipated effectively, performance becomes limited by protective physiological responses rather than fitness. CoreCtrl is built on current sports science and informed by research such as Peel et al. 2024. It supports sweat response, evaporative cooling, and helps reduce internal heat storage so you can sustain intensity when conditions are challenging.
CoreCtrl is not a stimulant, a coolant, or a replacement for hydration. It works alongside fluids and electrolytes, supporting your body’s existing cooling system. The outcome is not a spike in performance, but greater control, consistency, and resilience when heat would normally become the limiting factor.
For endurance athletes preparing for hot races or heat-focused training blocks, CoreCtrl offers a structured way to upgrade how the body handles thermal stress. It is designed to be integrated into your wider fuelling, hydration, and pacing strategy.
How does it work
CoreCtrl supports the body’s thermoregulation system, the physiological process that allows you to dissipate heat through sweating and evaporative cooling. By enhancing sweat gland activation and improving cooling efficiency, it helps the body shed heat more effectively during sustained efforts. This can contribute to lower internal heat accumulation and improved tolerance to thermal stress.
It does not artificially cool the body. Instead, it supports the natural mechanisms already built into your system. When combined with appropriate hydration and electrolyte intake, CoreCtrl helps maintain effective sweat production and cooling capacity, supporting performance when environmental stress would otherwise reduce output.
