Redcon1 Isotope is a 100% whey protein isolate delivering 25g of protein per serve with zero added sugar, zero lactose, zero gluten and only 120 calories. Whey protein isolate is processed to remove the majority of fat, lactose and carbohydrates, resulting in a fast-absorbing protein with a high amino acid density per gram. This makes Isotope well suited for post-workout recovery, between-meal supplementation and calorie-controlled nutrition plans.
The complete amino acid profile of whey protein isolate includes all nine essential amino acids and a naturally high concentration of BCAAs, particularly leucine — the primary amino acid responsible for initiating muscle protein synthesis. With zero added sugar, Isotope avoids the hidden calorie contribution of flavoured proteins sweetened with sucrose or fructose, keeping the formula lean and functional.
Isotope also supports appetite management by contributing to satiety after consumption. It dissolves cleanly in water or milk and is available in multiple flavours. Mix one serve in 200–300ml of liquid, ideally within 30–60 minutes following training for optimal recovery support.
The nutritional panel for this product is on its label. Serving size, servings per pack and the full ingredient list are shown on the pack — check it before use, as brands reformulate from time to time.
Mix one scoop with 250-300ml of cold water or milk. Take one serve daily, or as directed by a healthcare professional. Best used within 12 months of opening.
