Powerbar have replaced their Energize drink with two new drinks: IsoMax and IsoActive. IsoMax is based on IsoActive but is a higher performance energy drink that includes caffeine and PeptoPro protein hydroslate. This is the drink for serious athletes.Designed for hard workouts and racing, IsoMax uses the C2Max 2:1 proven carbohydrate mix. It provides a big 178KCal per 50g serving and packs in 420mg of sodium, 70mg of caffeine and 3750mg of PeptoPro protein hydrolysate. PeptoPro absorbs faster than whey protein isolate, prolonging performance by delaying fatigue and enhancing recovery.IsoMax includes the five main electrolytes lost in sweat, sodium, chloride, potassium, magnesium and calcium, and mixes extremely easily in only 500ml water and has a flavour that is not over-sweet.
