truefuels CoreCtrl™

Heat is one of the biggest limiting factors to performance there is. Your pace is still on plan, then your effort starts feeling harder. Heart rate creeps up, breathing gets ragged, and the pace you trained for slips away. Heat is pulling blood away from working muscles to cool your skin. Heat training, in response, has becoming it's own form of preparation for events. 

truefuels built CoreCtrl to help your body handle that heat fight before it starts, delivering a high dose of taurine alongside a full electrolyte spread you load in over the eight days before your race.

Sweat Earlier, Overheat Slower – The taurine dose is paired with potassium, calcium, magnesium, and Himalayan rock salt so your body starts cooling itself sooner and holds onto the muscle contraction and nerve signaling those minerals control, even as your core temperature climbs.

Prep, Don't Chase – Loading taurine for eight days before your race helps you sustain effort deeper into hot conditions, so your pace doesn't fall apart in the back half the way it usually does once temperatures climb.

Electrolyte Support – The electrolyte blend replaces what heat-driven sweat strips away fastest, so your muscles keep contracting properly and cramping shows up later, if at all.

During exercise, most of the energy your muscles produce turns into heat, and in a warm environment your body can't always shed it fast enough. A 2024 study led by Peel and colleagues linked eight days of taurine intake to earlier sweat onset, a higher whole-body sweat rate, and a drop in how much heat the body stores during exercise. The electrolyte side of the formula, potassium, calcium, magnesium, and sodium from Himalayan rock salt, replaces what sweat pulls out fastest so muscle contraction and nerve signaling stay steady under load. Piperine from black pepper extract rounds out the formula by improving how much of that taurine dose your body absorbs.

How to Use CoreCtrl

CoreCtrl™ is designed as an 8-serving preparation protocol, not a single-serving race-morning product.

For races: take 1 serving per day for 8 days, with your final serving on race morning or before your target event. Always test CoreCtrl™ in training before using it for a race.

For training: take 1 serving per day for 8 consecutive days before or during a warm-weather training block, heat-focused camp, or period where you expect multiple demanding sessions in hot conditions.

For lighter athletes: follow the gradual protocol: 1 serving per day for 2 days, then 1 day off. Repeat until all 8 servings are complete

Mix 1 serving with 500 mL / 16.9 fl oz water. On training or race days, take your serving 30–60 minutes before exercise. Practice in training before competition so you can dial in hydration, fueling, electrolyte intake, and pacing.
