Winner of the gold for women’s running nutrition product – post race category – USN R3 Excell
The nutrient requirement in athletes is usually highest immediately after intense and prolonged physical activity. The 30 - 45 minute window after training or events may be a crucial time during which the body races to recover as quickly as possible. The body’s evolutionary instinct to immediately replace muscle glycogen means that it will use whatever nutrients are available, including amino acids present in muscle tissue for this purpose, which may result in muscle wastage. By rapidly supplying carbohydrates to replace glycogen, as well as protein to replace amino acids, the body recovers more quickly, without breaking down as much muscular protein.

USN’s R3 Excell is precisely formulated as a high protein drink with vitamins, minerals, electrolytes and sugar, to use after long periods of intense physical activity such as military training, Iron Man events, marathons etc. as well as shorter, highly intensive activities like sprinting, power-lifting, weight-lifting, rugby etc. The carbohydrates consist of a ratio of long chain glucose polymers. R3 Excell has been formulated to form an isotonic drink (if prepared correctly). Protein is supplied in the form of premium whey protein. R3 Excell is a light, refreshing, fruit flavoured drink.

Core benefits of R3 Excell:

Electrolyte, glycogen and amino acid replenishment.

Muscle-building amino acids to prevent muscle breakdown during intensive exercise.

21 grams whey protein isolate & triple stage synergistic carb matrix.

Who should use it?
Endurance athletes, team sport players and anyone requiring recovery from other intense physical activities.
