USN Purefit Range


We’ve been testing these products for a while now and in short we absolutely love them! Certainly the best tasting energy drink – think VitaminWater compared to Coke. We love the fact that the drinks aren’t sickly sweet and have a natural flavour. More importantly, do they work?
Our bodies haven’t been subjected to scientific scrutiny but based on how we feel, yes indeed.

The Enduro is described as a performance energy and rehydration drink, A 3-Stage Glycomatrix carbohydrate drink for sustained energy during training and racing. The total sugar content per 100g is 36.6g and the Pro Enduro has 19.4g.

USN Enduro has been scientifically formulated to provide athletes with a light, refreshing and functional sports drink. It combines high, intermediate and low Glycaemic Index (GI) carbohydrates, which have been shown to promote performance and improved exercise tolerances, as well as muscle recovery, during physical exercise. This unique combination of performance ingredients assists with the sustained and continuous supply of energy to optimally fuel you for your performance requirements, while still promoting stable blood sugar levels.

The Pro Enduro is a high performance endurance drink, containing impact carbohydrates, amino acids and electrolytes for optimal performance and hydration during intense physical activity.

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, in conjunction with a high-molecular-weight Waxy Maize 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 1/3 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.
