PRO:LONG is part of Myproteins Nutrient Timing Programme which is designed to satisfy your body's specific nutritional requirements before during and after exercise or competition.

PRO:LONG is a unique formula which combines carbohydrates, protein and electrolytes to encourage hydration and energy supply during physical activity. Taken during exercise or competition PRO:LONG helps you maintain the physical intensity you demand.

The scientifically driven combination of carbohydrates and electrolytes has been developed to encourage ongoing hydration during exercise. A small drop in hydration or electrolyte balance can have a profound effect on physical performance, so it is crucial that you consume fluid throughout activity. We have also included protein and amino acids to maintain protein synthesis and reduce catabolism as muscle can often be broken down as a source of energy during prolonged exercise.
