Protein

Protein is one of the three macronutrients, alongside carbohydrates and fats. Made up of amino acids, it is the building material for your muscles, but also for your skin, your hair and many enzymes. For an athlete, the logic is simple: training creates micro-damage in your muscle fibres, and protein supplies the amino acids needed to repair and strengthen them.

Protein contributes to the maintenance and growth of muscle mass, and to the maintenance of normal bones (authorised EFSA claims). A protein is called complete when it provides the nine essential amino acids your body cannot make on its own.

Whey (milk protein) remains the benchmark: it is a complete dairy protein, quickly absorbed and rich in leucine, the key amino acid for building muscle. Alongside it you will find casein, plant proteins and gainers, each with its own role. The sections below help you pick the one that genuinely fits your goal.

The right choice depends on your goal and the time of day. Here are the main families in the QNT range:

• Whey (fast protein): ideal around training and first thing in the morning. It is absorbed quickly and gets muscle synthesis going again fast. At QNT: Prime Whey, Delicious Whey and Light Digest Whey (formulated for gentler digestion).
• Whey isolate: the purest option, very low in lactose, carbs and fat. Perfect when you are cutting or if you struggle to digest lactose. At QNT: Metapure Whey Isolate Zero.
• Casein (slow protein): digested gradually over several hours, perfect at night or between meals that are spaced far apart. At QNT: Casein Protein Micellar.
• Plant protein: 100% plant-based, lactose-free, for vegans and people with intolerances. At QNT: Vegan Protein.
• Gainer: protein plus carbs for people who find it hard to put on weight. At QNT: 3000 Muscle Mass Gainer and Metapure Mass.

The winning habit: pairing whey (fast) and casein (slow) at the right moments covers all your needs.

This is one of the most common questions, and the answer comes down to the filtration process.

Whey concentrate keeps a small share of the carbs and fat that come from milk. It offers excellent value for money and a high protein content: a very solid everyday choice for most athletes. At QNT, Prime Whey and Delicious Whey follow this approach, with real attention paid to taste.

Whey isolate goes through advanced filtration that removes most of the lactose, carbs and fat. The result is a very pure protein, often around 90% and above, ideal when you are watching your calories during a cut or when you do not digest lactose well. That is exactly where Metapure Whey Isolate Zero sits.

In short:

• Everyday muscle building on a controlled budget: whey concentrate.
• Cutting, maximum purity, lactose sensitivity: whey isolate.

And if digestion is your weak point, Light Digest Whey is designed to limit digestive discomfort.

The amount depends on your bodyweight and your goal. The reference ranges commonly used in sport are:

• Maintenance / moderate activity: roughly 1.2 to 1.6 g of protein per kg of bodyweight.
• Muscle building: roughly 1.6 to 2.2 g/kg.
• Weight loss (preserving muscle): roughly 1.6 to 2 g/kg, with protein also helping with satiety.

A 65 kg woman who trains and wants to lean out will therefore often aim for 100 to 130 g of protein per day, food included. The smart approach: spread your intake across the day (every 3 to 5 hours), with around 20 to 30 g per serving to optimise muscle synthesis. Whey does not replace meals: it tops things up when food alone is not enough.

For a leaner female physique without piling on calories, Skinny Protein is formulated with exactly this in mind. For lightness and digestion, Light Digest Whey is also a good everyday ally.

The when matters almost as much as the how much, but it is more flexible than people think. If you have ever wondered about the best time to take whey protein, here is the practical view:

• After training: the most popular moment. A serving of whey quickly delivers amino acids to support recovery and muscle growth.
• On waking: after a night with no intake, a fast protein gets the engine running again.
• In the evening: go for a casein (slow protein) like Casein Protein Micellar, which releases its amino acids gradually during the overnight fast.
• Between meals: a shake or a protein snack helps you hit your daily total.

The famous anabolic window after a workout is real but wide: the main thing is to reach your total intake across the day. Quick prep: 1 scoop in 200 to 300 ml of water or plant milk, in a shaker. For a ready-to-drink format, the Protein Shake and Iso Whey (protein water) are perfect to take with you.

Not everyone enjoys milky, creamy shakes. Clear protein, or protein water, is a light, fluid and thirst-quenching alternative, closer to a fruity drink than a milkshake.

Based on very pure whey isolate, it delivers the protein of a classic shake with a clear texture, little fat and a handy format. It is ideal:

• after a session, when you want something fresh rather than creamy,
• in summer or during hot spells,
• to add variety so your palate does not get bored.

At QNT, discover Iso Whey protein water and Protein Water: handy, refreshing and high in protein. It is also a great entry point for anyone just starting out who finds traditional shakes too heavy. You get quality protein in a drink that is easy to fit into your day, at the gym or at the office.

Protein is not limited to shakes. To reach your daily target without monotony, protein foods are real allies, and often the trick that makes the difference over the long run.

The QNT range lets you vary your sources and your treats:

• Protein Pancake: pancakes high in protein and low in sugar, perfect at breakfast or as a snack.
• Protein Noodles: a filling, simple, protein-rich meal base.
• And on the savoury snacking side, the idea is to swap classic crisps or popcorn for higher-protein alternatives, so you can satisfy the urge to munch without sabotaging your goals.

The benefit is twofold: you increase your protein while keeping your diet varied and appetising. A protein snack keeps you full for longer and helps curb afternoon sugar cravings. Combine powders, drinks and protein foods to suit your mood: it is consistency, not perfection, that builds results. Always keep a healthy protein option within reach, at home and at work.

Protein powder is not just for bodybuilders. It is for anyone whose needs are rising or whose diet is short on protein:

• athletes who are building muscle or cutting,
• people who stay active day to day,
• women looking to lean out while preserving muscle mass,
• busy lifestyles that make it hard to cook enough protein.

On digestion: if standard whey sits heavily with you, there are two options. Light Digest Whey, formulated for more digestive comfort, or a whey isolate (Metapure) that is almost lactose-free. Vegans and people with lactose intolerance turn to Vegan Protein.

The range also includes collagen (Collagène Care), the structural protein most abundant in skin, joints and tendons, whose natural production declines with age.

Every QNT protein is developed and made in Belgium (made in Belgium), with strict quality control. You choose a protein that is reliable, tasty and matched to your goal.
