The SiS REGO Rapid Recovery Drink is a post-workout recovery powder designed to help athletes refuel and repair after demanding exercise. Combining fast-acting carbohydrate with high-quality plant-based soy protein, it provides a convenient all-in-one recovery drink for runners, cyclists, triathletes, gym-goers and endurance athletes who need to prepare for their next training session.

Each 50g serving delivers approximately 22g of carbohydrate and 21g of soy protein, alongside a complete amino acid profile enhanced with 2.5g of L-Leucine. The carbohydrate helps replenish depleted glycogen stores, while protein contributes to the maintenance and growth of muscle mass. REGO Rapid Recovery also contains a blend of vitamins and minerals, including Vitamin C and B vitamins, to complement post-exercise nutrition and support normal energy metabolism.

For simple post-training recovery, mix 50g – around two full scoops – with 500ml of cold water, shake well and consume within approximately 30–60 minutes after exercise. Its smooth, water-based formula means there is no need to mix it with milk, making SiS REGO Rapid Recovery a practical choice after long rides, runs, races, hard gym sessions and back-to-back training days.
