The SiS Rego Rapid Recovery protein shake is a comprehensive recovery product. In addition to proteins, the SiS Rego Rapid Recovery contains a mix of carbohydrates, electrolytes, and vitamins. This unique formula contributes to recovery of muscle fibres, the carbohydrate reserve, and moisture balance.

Proteins assist recovery of damaged muscle fibres after physical exercise. This makes proteins essential building blocks for quick recovery. In addition, the Rego Rapid Recovery contains 2 grams of leucine (BCAA). BCAAs are important in protein synthesis and preventing muscle damage after taxing physical exertion. With 20 grams of protein per protein shake, the SiS Rego Rapid contains an ideal amount of proteins for rapid recovery.

Carbohydrates are the most important fuel for endurance athletes. During intense physical exercise, your body relies on the stored carbohydrate reserves in the muscles and the liver. Besides proper protein intake, replenishing the carbohydrate reserves is also essential for quick recovery. With 22 grams of carbohydrates per Rego Rapid Shake, this SiS protein shake also contributes to refilling the carbohydrate reserves in the muscles. The added electrolytes improve moisture absorption. It's for good reason that this SiS protein powder bears the name Rego Rapid. You'll be good to go again in no time!

Lekkere recovery shake!

Na de aardbei nu ook de chocolade variant geprobeerd. Persoonlijk vind ik deze nog beter te doen dan de aarbei. Het enige wat ik bij deze van SIS heb is dat ik het idee heb dat het poeder minder goed oplost dan het poeder van de Powerbar Recovery shakes die mijn fietsvrienden gebruiken. Zij zijn al klaar met drinken als ik nog sta te schudden...


  • Smaak


  • Oplossend vermogen
