You've dialed in your carbs, your hydration, your sleep. But somewhere deep into a hard effort, your legs are still moving and your brain just... checks out. Focus goes first, then pacing discipline, then the mental edge that separates a good race from a great one. Here's what most athletes don't realize: your muscles and your brain are competing for the same fuel — and your brain is usually the one that loses. Ketone-IQ is the exact ketone fuel trusted by Tour de France champions, Navy SEALs, and Ironman World Championship podium finishers. Sugar-Free, Crash-Free — Ketone-IQ delivers clean fuel without glucose spikes or the inevitable slump that follows. Unlike caffeine or sugar, ketones provide a steady energy curve that keeps you operating at a high level for hours, not minutes. A Smarter Fuel Source — The active ingredient — R-1,3-Butanediol — is a next-generation ketone precursor that your body converts into D-beta-hydroxybutyrate with near-100% efficiency. Research shows ketones can generate energy more efficiently than glucose alone, acting as a premium fuel for both working muscles and a hard-charging brain. Stack It with Your Carbs — Ketone-IQ isn't a replacement for your race nutrition. It's an upgrade. Athletes stack it alongside their carbohydrate fueling strategy to give the body a second fuel source, sparing glycogen and extending how long you can sustain high output. What Are Ketones? Ketones are one of the most efficient energy molecules your body can use. Usually, the body makes them down from fat when you are fasting, have low carbohydrate availability, or are in extended exercise. Exogenous ketones essentially bypass that requirement. When you take Ketone-IQ, R-1,3-Butanediol — a pure, single-ingredient ketone precursor — is rapidly absorbed and converted into circulating ketones, elevating blood ketone levels into the clinically studied optimal range of 1.0–2.5 mmol/L within 30–60 minutes. At that level, ketones can fuel both muscles and the brain simultaneously, help preserve glycogen reserves during extended efforts, and support faster recovery between sessions. Clinically studied research shows ketone supplementation led to a 15% increase in mean power output following a 3-week overreaching training block. How to Use Ketone-IQ No Caffeine Multiserving Pre-workout: Take 1–2 servings (roughly 25–50ml) 20–30 minutes before training or competition to elevate ketones ahead of your effort. During long efforts: Take an additional serving mid-effort for efforts exceeding 2 hours to maintain ketone levels and support mental clarity. Daily use: Take 1–3 servings throughout the day — morning for focus, pre-session for performance, and post-session for recovery support. Pro tip: The multiserving bottle is designed for flexible dosing — measure your preferred serving size, cap it, and keep it in your kit bag. No wrappers, no single-use packaging. Elite cyclists competing in the Tour de France, Ironman World Championship finalists, and Olympic-level swimmers have publicly credited Ketone-IQ as part of their daily performance routine. Sam Laidlow, 2023 Ironman World Champion, uses it for workout consistency, blood sugar stability, and the mental boost that holds up under race-day pressure. This isn't just another energy supplement. This is the fuel your brain and body have been missing.
