Carb Hack is an educational tool. The information, formulas, and recommendations provided on this site are for general informational purposes only and are not intended as medical advice, diagnosis, or treatment.

The recipes and formulations generated by the builder tool are user-configured. You are solely responsible for verifying the safety and suitability of any mix you create and consume. Individual tolerance to carbohydrates, electrolytes, caffeine, and other ingredients varies widely.

Consult a qualified healthcare professional or registered dietitian before making changes to your nutrition strategy, especially if you have any medical conditions, food allergies, or are taking medication.

Carb Hack does not guarantee the accuracy or completeness of any nutritional data, calculations, or scientific references presented on this site.

Caffeine is a potent stimulant. Overconsumption can cause serious adverse effects including rapid heartbeat, cardiac arrhythmia, seizures, and in extreme cases, death. The FDA recommends that healthy adults consume no more than 400mg of caffeine per day from all sources combined (coffee, tea, pre-workout supplements, and sports nutrition).

Measurement precision. Caffeine powder is active at very small quantities. A measurement error of even 1 gram can represent a medically significant overdose. If you choose to add caffeine to a formulation, you must use a precision scale accurate to at least 0.01g. Carb Hack is not responsible for dosing errors.

Incomplete mixing and batch preparation. If caffeine powder is not thoroughly and uniformly dissolved or dispersed in your mix, individual servings drawn from the same batch may contain significantly more or less caffeine than intended. This is especially dangerous when preparing larger batches, dry pre-mixes, or powdered blends where caffeine can settle, clump, or distribute unevenly. Always mix caffeine into liquid directly and stir or shake thoroughly. Do not rely on dry-blending alone to achieve uniform caffeine distribution.

Vulnerable populations. Caffeine should be avoided or limited by individuals who are pregnant, nursing, under 18, or who have heart conditions, anxiety disorders, or caffeine sensitivity. Consult a physician if you take any medication that may interact with caffeine.

Assumption of risk. By adding caffeine to any formulation using the Carb Hack builder, you acknowledge that you understand these risks and accept full responsibility for the safe handling, accurate measurement, thorough mixing, and appropriate consumption of caffeine in your mix.

Carb Hack is designed for endurance athletes who require elevated carbohydrate intake during prolonged physical activity. The formulations produced by this tool may contain high concentrations of sugars and carbohydrates — in some cases 90g or more per hour — that are appropriate only during sustained exercise where the energy is being actively metabolized.

Not for general consumption. These formulations are not intended as everyday beverages or casual drinks. Regularly consuming high-sugar sports nutrition products may increase the risk of adverse health outcomes including obesity, type 2 diabetes, insulin resistance, metabolic syndrome, and dental decay.

Pre-existing conditions. Individuals with diabetes, pre-diabetes, insulin resistance, or other metabolic conditions should consult a physician before using high-carbohydrate sports nutrition of any kind, including formulations created with Carb Hack. The carbohydrate loads involved may cause dangerous blood sugar spikes in susceptible individuals.

Context matters. The sports science research referenced on this site studies carbohydrate intake during endurance exercise, where rapid glucose uptake by working muscles mitigates blood sugar accumulation. Those findings do not apply to sedentary or low-activity contexts. You are responsible for ensuring your carbohydrate intake is appropriate for your actual activity level and health status.
