Isotonic Drink Long – Strawberry Basil 40g

MX3 Isotonic Drink Long Effort is an endurance energy drink developed in partnership with the Ultra Sport Science Foundation, formulated for high-intensity efforts exceeding 2.5 hours. Whether you are racing a mountain ultra, completing a long alpine route, or pushing through an extended cycling effort, this isotonic drink delivers progressive, stable energy without digestive compromise.

The formula centres on isomaltulose, a low glycaemic index carbohydrate that releases energy gradually and steadily. Unlike maltodextrin-based drinks, isomaltulose prevents blood sugar spikes and crashes — a key advantage during long efforts where glycaemic stability directly affects pacing and mental focus.

The isotonic formula limits digestive discomfort during effort and ensures optimal nutrient absorption. This makes it a reliable endurance energy drink for athletes who struggle with conventional sports drinks at high intensity or in heat.

BCAAs (leucine, valine, isoleucine) reduce muscle damage and trauma caused by prolonged effort. Marine magnesium, sourced from Mediterranean seawater and of French origin, supports muscle, joint and nervous system function while reducing fatigue. Vitamins C and E provide antioxidant protection against exercise-induced oxidative stress. A complete B-vitamin complex (B1, B2, B3, B6) supports energy metabolism throughout the effort. Sodium and potassium maintain fluid balance and normal muscle function.
