Muscle Nation Sour Protein Water is a crisp, light, and tangy alternative to traditional milky shakes, formulated to support lean muscle repair and daily hydration. Created for athletes, gym-goers, and active Australiaers who prefer a fruity, thirst-quenching recovery drink, this premium hydrolysed collagen and whey protein isolate blend delivers 23g of protein per serve with virtually zero fat and low carbohydrates.

Key Benefits & Features

• 23g High-Quality Protein: Combines hydrolysed collagen peptides and whey protein isolate to drive muscle repair and recovery.

• Mouth-Watering Sour Flavours: Delivers a bold, tangy confectionery taste that makes hitting daily protein targets crisp and enjoyable.

• Light & Refreshing Alternative: Mixes completely clear with a juice-like consistency, eliminating the heavy or bloated feeling of milky shakes.

• Enhanced with Electrolytes & BCAAs: Includes essential branched-chain amino acids and key minerals to support cellular hydration and endurance.

• Virtually Zero Fat & Low Sugar: Easily fits into calorie-controlled fat loss plans, lean muscle regimes, and low-carb lifestyles.

How It Works

Muscle Nation Sour Protein Water combines fast-digesting hydrolysed collagen peptides with micro-filtered whey protein isolate to supply working muscles with a comprehensive amino acid profile. Unlike standard dairy protein powders, this clear formulation dissolves cleanly in cold water, promoting rapid gastric emptying and swift amino acid delivery directly into the bloodstream.

The added hydrolysed collagen delivers targeted structural amino acids to support healthy joints, ligaments, tendons, and connective tissues strained during intense lifting or cardio sessions. Combined with essential electrolytes and BCAAs, it fuels post-exercise recovery, halts muscle breakdown, and restores fluid balance in one revitalising drink.

Recommended Use

• Serving Size: Mix 1 rounded scoop (approx. 30g) with 350–500ml of ice-cold water in a shaker bottle.

• Mixing Tip: Shake vigorously for 20–30 seconds, then let the shaker sit for 1–2 minutes to allow natural foaming to clear into a translucent drink.

• Timing: Consume immediately after workouts to kickstart muscle recovery, or sip throughout the day between meals to boost daily protein intake.
