Why Choose SiS REGO Rapid Recovery?

SiS REGO Rapid Recovery combines carbohydrate and plant-based soy protein in one post-exercise drink. It is designed for athletes who want both carbohydrate and protein after training or competition rather than a conventional protein-only shake.

The current formula uses soya protein isolate and maltodextrin, with a complete amino acid profile enhanced by 2.5g of L-leucine per serving. It also contains a blend of vitamins and minerals.

Nutrition varies slightly by flavour. Chocolate provides 21g protein and 22g carbohydrate per 50g serving, Strawberry provides 21g protein and 23g carbohydrate, and Vanilla provides 22g protein and 23g carbohydrate.

Soy Protein, Carbohydrate and L-Leucine

Each serving provides high-quality soya protein isolate together with maltodextrin as the carbohydrate source. Science in Sport also adds 2.5g of L-leucine to the complete amino acid profile.

Unlike the current SiS BETA Recovery formula, which uses whey protein and a larger 100g serving, REGO Rapid Recovery uses plant-based soy protein and a 50g serving.

Vitamin and Mineral Blend

REGO Rapid Recovery contains added vitamins and minerals including vitamins C, E, B1, B2, B6 and B12, niacin, folic acid, biotin, pantothenic acid, iron, zinc and iodine.
