SiS Rego Rapid Recovery Powder - 1.5kg

SiS Rego Rapid Recovery Powder – 1.5kg

The bulk-pack format of SiS's flagship daily recovery powder — built for endurance athletes, runners, cyclists, triathletes, and serious lifters whose post-training nutrition determines next-session performance. Particularly suited to those running long competition prep blocks, athletes doing double-session training days where rapid post-workout recovery is non-negotiable, lifters in heavy training phases, and anyone wanting a clinically-formulated all-in-one recovery drink that delivers protein, carbs, vitamins, and minerals in a single serving without juggling multiple supplements.

What separates SiS Rego Rapid Recovery from the typical recovery product on the market comes down to the comprehensive all-in-one recovery formula. Most basic recovery supplements deliver only protein or only carbs — Rego Rapid Recovery delivers both in clinically-relevant ratios alongside added vitamins and minerals, all engineered to address the post-exercise recovery window from multiple angles. The protein component supports muscle protein synthesis and repair; the carbohydrate component drives glycogen replenishment (which is critical for next-day training quality, particularly for endurance athletes); and the vitamin and mineral profile addresses electrolyte losses and the broader micronutrient demands of heavy training. Clinical research consistently shows that post-exercise glycogen replenishment is significantly faster when carbs are paired with a meaningful protein dose compared to either macronutrient alone — which is the central science behind the Rego formulation. The 1.5kg bulk pack provides sustained months of daily recovery use at the lowest cost-per-serving in the range, particularly relevant for those whose daily training load demands consistent recovery support.

Science In Sport manufactures Rego Rapid Recovery in the UK in facilities certified to GMP standards, with rigorous quality control across the range. Importantly, this product is Informed Sport certified — meaning batches are independently tested for WADA-banned substances at an ISO 17025 accredited lab. For competing tested-pool athletes in Sri Lanka, that's the highest level of third-party verification available.

• All-in-one recovery formula — protein, carbohydrates, vitamins, and minerals in a single post-training serving
• Clinically-relevant carb-to-protein ratio — drives faster glycogen replenishment and supports muscle protein synthesis simultaneously
• Added vitamins and minerals — addresses electrolyte losses and broader micronutrient demands of heavy training
• 1.5kg bulk pack — sustained months of daily supply at the lowest cost-per-serving in the range
• Informed Sport certified — credible for tested-pool athletes; a serious recovery supplement for athletes equally relevant as supplements for running recovery or recovery supplements for gym

Pair it with a quality whey protein from our protein and recovery range to round out a complete daily training and recovery stack.

Mix 1 serving (per label) with 500ml of cold water in a shaker, seal, and shake well for 10–15 seconds. Consume within 30 minutes after training to take advantage of the optimal post-exercise recovery window, when glycogen replacement and muscle protein synthesis rates are highest. Particularly important after long endurance sessions, heavy resistance training, or back-to-back training days where recovery determines next-session performance. For double-session training days, consider using Rego after the first session to support glycogen replacement before the second. Consult a healthcare professional before use if you are pregnant, nursing, taking prescription medications, or have an existing medical condition. Store with the lid sealed in a cool, dry place away from direct sunlight..
