¹Las soluciones de carbohidratos y electrolitos contribuyen al mantenimiento del rendimiento de resistencia durante el ejercicio de resistencia prolongado.

²La L-Carnitina ayuda a mantener los niveles de energía durante períodos prolongados en competición/ejercicio intenso. Mejora la resistencia y ayuda a mantener el esfuerzo máximo en momentos de alta demanda física. La L-carnitina hace que el metabolismo energético sea más eficaz y protege el metabolismo energético celular.

³El Magnesio contribuye a la función muscular normal, a la reducción del cansancio y la fatiga, y al equilibrio electrolítico.

⁴La Vitamina C es necesaria para mantener la energía y la vitalidad general, y contribuye a la reducción del cansancio y la fatiga. La Vitamina C es un cofactor en la síntesis de carnitina, que desempeña un papel en la producción de energía en las mitocondrias. La Vitamina C contribuye a la protección de las células frente al estrés oxidativo y al mantenimiento de la función normal del sistema inmunitario durante y después del ejercicio físico intenso.
