ISOSTAR, PIONEER OF SPORTS NUTRITION

ISOSTAR is the first sports nutrition brand born in Europe: it was in Switzerland in 1977. The isotonic drink HYDRATE & PERFORM is emblematic because it has been supporting endurance athletes for 40 years. Today the range meets all the nutritional needs of physical effort: hydration, but also the carbohydrate, protein and micronutrient intake necessary for each athlete to maintain his level of performance.

Since the 90s ISOSTAR is a French brand, located a few kilometers from Toulouse. The Energy and Protein Bars are produced in Revel, but the production of Hydrate & Perfom drinks has remained in Switzerland in the original workshop.

It is for the efficiency and the quality of the products that many recognized athletes in their respective discipline (Trail, marathon, bike, triathlon) have chosen to train with ISOSTAR. The brand accompanies them in their daily challenges and their biggest sporting challenges.
