CONSEIL DU NUTRITIONNISTE
Preworkout effectiveness depends on active ingredient doses matching clinical research. Le "pump" from citrulline augmente blood flow; caffeine boosts CNS alertness and lipides burning; beta-alanine buffers muscle lactic acid for extended endurance. Timing matters: consume 15-30 minutes pre-workout for optimal absorption.

MYTHE #4: You Build Tolerance and Besoin Supérieur Doses
RĂALITĂ: Caffeine tolerance develops (requiring 2-semaine breaks), but beta-alanine and creatine benefits remain consistent. Strategic cycling (5 jours on, 2 jours off) maintains responsiveness tandis que preserving muscle carnosine stores. La plupart users don't besoin dose escalation.

| Strength & Power | | Caffeine enhances max strength and power output by 2-8%. Creatine fournit ATP energy substrate. Optimal for strength athletes. |
| Endurance & Running |  | Beta-alanine delays fatigue (la plupart useful for 2-10 minute efforts). Caffeine améliore aerobic performance. Less critical for ultra-distance (>2 hours) due to GI absorption limits. |
| Lipides Loss | | Caffeine boosts metabolic rate 3-5%; enhances lipides oxidation and appetite suppression. Pair avec calorie deficit. Not magicâsoutient adherence to training intensity and diet. |
| Pre-DiabĂšte/SOPK |  | Caffeine peut temporarily raise glucose sanguin; monitor response. La plupart formulas sont sucres-gratuit. Consult doctor avant utiliser if insulin sensitive. Peut interfere avec medication timing. |
