USN’s PRO ENDURO has been scientifically developed with the performance athlete in mind. A blend of highly essential and conditionally essential amino acids have been blended together with a unique carbohydrate matrix that includes the patented Vitargo®, an agglomerated barley starch, to drastically accelerate glycogen uptake, refuelling and utilisation during and after strenuous  training and events.

Among the most beneficial and effective supplements in any sports nutrition programme are Branched Chain Amino Acids (BCAAs). These are the essential amino acids leucine, isoleucine and valine. The combination of these three essential amino acids makes up approximately a third of skeletal muscle in the human body, and plays an important role in protein synthesis, and thus muscle growth and repair. Glutamine is the most abundant amino acid found in the human body and is arguably the most important in the process of building muscle and gaining strength.

Citrulline malate again may enhance natural arginine levels and promote aerobic energy production as well as post-training recovery – a reduction in the sensation of fatigue has been shown, with reduced levels of lactic acid and ammonia quite evident. Beta-alanine promotes this reduction in fatigue and increase in aerobic energy to an even greater extent, whilst also increasing anaerobic energy, muscular strength and power output.

The refreshing USN PRO ENDURO will allow active individuals to train harder for longer, with stabilised energy levels to support improved levels of stamina and recovery.
