Intra-Workout Supplements for Athletes and Sportspeople
Our selection of Yamamoto Nutrition intra-workout supplements is dedicated to martial arts and combat sports athletes who want to maintain constant energy, hydration, and focus throughout the entire training session.
In combat sports, where sessions can be long and intense with sparring, technical work, and conditioning, refueling the body during effort makes the difference between an explosive finish and a drop in performance in the final rounds.
The range includes sources of high molecular weight carbohydrates with rapid gastric emptying like GlycoBol Cluster Dextrin™ and GlycoBol Performance Cluster Dextrin™, designed to provide sustained energy without weighing down the stomach.
For complete support with carbohydrates and amino acids, you'll find Energan, Charge Performance, Legionarius, and the premium formulas Dark Katana Carbo with carbohydrates and Dark Katana No Carbo for those who prefer an intra-workout without carbohydrate intake.
Choose the formula that best suits your training style to never lose intensity from the first to the last minute.
