Creamy, milkshake like and simply 21g high-quality whey protein.

  • Great taste

    Richer, creamier shake.

  • Added friendly bacteria

    Easier on the stomach.

100% Whey is made with instantised, ultra-filtered whey protein concentrate – a form of protein that keeps more of the natural nutrients from whole whey. With around 70% protein, it naturally contains healthy fats, carbohydrates, and bioactive peptides.

That fuller nutritional profile gives it a creamier texture and a richer, more satisfying taste.

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.

Whey protein concentrate gives your body a fast, high-quality supply of those building blocks. It delivers all the essential amino acids – including leucine, the trigger for muscle growth – and keeps more of the natural nutrients in whole whey, such as healthy fats and bioactive peptides. With added enzymes and friendly bacteria, it digests smoothly so more of that protein is absorbed and put to work.

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.<

Each serving of 100% Whey delivers 21g of protein in a rich, creamy shake.

Made with whey concentrate, it retains more of the natural nutrients in whole whey – including healthy fats and bioactive peptides – for a fuller profile. It’s the fuel your body needs to recover, rebuild, and stay strong day after day.

    Frequently Asked Questions

    What you need to know

    Complete Diet Protein is suitable for vegetarians but not vegans, as it contains dairy-derived protein. It contains milk and soya (soya lecithin), and may contain traces of gluten and egg, so it isn't suitable for anyone with those allergies. As with all the products, check the ingredients panel on the pack if you have a serious allergy or intolerance.

    For a full meal replacement, mix 60g (2 scoops) with 350ml of water until smooth; for a lighter high-protein shake, mix 30g (1 scoop) with 175ml of water. It works well as a quick breakfast, a mid-morning or lunch option, or a post-workout shake — drink it immediately once mixed. Use it as part of a varied, balanced diet rather than as your only source of nutrition. It isn't suitable for anyone under 16

    It's designed to be used as part of an energy-restricted diet for weight control. Under the authorised wording for meal replacements, substituting one daily meal of an energy-restricted diet with a meal replacement can contribute to maintaining weight after weight loss, and substituting two daily meals can contribute to weight loss — in both cases as part of a calorie-controlled diet, not on their own. Its controlled calories, quality protein and 23 vitamins and minerals make it a practical option for anyone managing their intake.

    A standard protein powder is built almost entirely around protein, whereas Complete Diet Protein is designed as a balanced meal in a shake. Alongside its 26g of protein it includes slow-release carbohydrates, healthy fats, fibre and 23 vitamins and minerals, so it provides broader nutrition rather than protein alone. Choose a whey powder like 100% Whey or Instant Whey Pro when you simply want to top up protein around training; choose Complete Diet Protein when you want a convenient, rounded meal — for example when you're short on time or skipping a cooked meal.

    Complete Diet Protein is a meal replacement shake that delivers the nutrition of a balanced meal in one serving. Each 60g serving provides 26g of quality protein from a blend of dairy and plant sources (milk, whey, pea, rice and pumpkin), slow-release carbohydrates from waxy maize starch, healthy fats, fibre, and 23 essential vitamins and minerals. Added digestive enzymes and friendly bacteria help keep it smooth and easy to digest. It comes in Chocolate, Strawberry & Raspberry and Vanilla Fudge.
