    PRODUCT INFO

    Instant Whey™ Pro is more than a protein shake – it’s the foundation of progress.

    Each serving delivers 24g of protein at just 108kcal, making it a smart choice when you want strength without the excess. With added enzymes and friendly bacteria, it’s designed to work with your body so you can train hard and recover stronger.

    Protein is essential for muscle repair and growth, yet hitting the right amount through food alone can be a challenge. That’s where Instant Whey™ Pro steps in – helping your body repair today so you’re ready for tomorrow.

    Instant Whey™ Pro also includes LactoSpore®, a well-researched friendly bacteria.

    UNDER THE SURFACE

    Protein isn’t just for training – it’s the raw material your body uses to build and repair itself. Muscles, skin, hair, nails, enzymes, even your immune system all rely on it.

    Training pushes your body's demand for protein even higher. Every session creates tiny tears in muscle fibres – the signal to grow stronger – but without protein, they can’t rebuild. Recovery slows, fatigue lingers, and progress stalls.

    Instant Whey™ Pro delivers a lean, high-quality blend of whey concentrate and isolate – giving you all the essential amino acids, including leucine, the trigger for muscle growth. With added enzymes and friendly bacteria, it digests smoothly so more of that protein is absorbed and put to work where it matters.

    In the short term, that means fuel your body can use and quicker recovery after training. Over time, it helps you maintain lean muscle, supports your metabolism, and strengthens the systems you rely on – keeping you strong and capable in both training and life.

    HOW TO USE

    Consume up to 3 servings per day, ideally post-workout.

    Mix 30g with 180–200ml water or skimmed milk in a shaker or blender. Adjust the liquid to your taste. Once mixed, consume immediately.

    For a quick, protein-rich dessert, mix 100g Greek yoghurt with 30g Instant Whey™ Pro.

    For accuracy, we recommend weighing rather than relying on the scoop.

    This product is a food supplement and should be used in conjunction with a varied and balanced diet and a healthy lifestyle, not as a substitute for such. Do not exceed the stated daily dose. Not intended for use by anyone under 16. Keep out of reach of young children.
