Each package displays a “best before” date. When unopened and stored in a dry place, our products retain their quality until that date. Once opened, we recommend using powders within a few months for the best taste and solubility.

MBN (Muscle Body Nutrition) is our own brand, and our supplements are manufactured within the EU under strict quality standards (GMP/HACCP). This allows us to maintain control over the origin of raw materials and the quality of the final product.

Yes. Our products are manufactured in certified facilities and undergo quality controls for composition and purity, among other factors. This ensures that what’s listed on the label is actually in the container.

Our products are designed for athletes of all levels. If you’re a competitive athlete subject to anti-doping regulations, always check the label and, if in doubt, consult your sports federation or a sports physician, as the athlete is solely responsible for the substances they use.

We strive for clear, honest labels. Each product clearly lists exactly which ingredients, sweeteners, and flavorings are used. You’ll find the full list of ingredients and nutritional information on the product page.

Because MBN is our own brand, we supply directly without middlemen. As a result, you pay for the quality of the product and not for extra markups in the supply chain.

Whey concentrate is an all-around choice for daily use; whey isolate contains more protein per serving and fewer carbohydrates and lactose; casein is released more slowly and is great for the evening; and our plant-based (vegan) proteins are ideal if you avoid dairy. Not sure which one to choose? We’d be happy to advise you based on your goals.

Isolate is filtered more thoroughly, so it contains more protein and less fat, carbohydrates, and lactose per serving than concentrate. Concentrate is often a bit more affordable and has a creamier taste. For most athletes, concentrate works just fine; isolate is useful if you’re lactose-intolerant or following a strict diet.

For active athletes, the recommended intake is typically about 1.6 to 2.2 grams of protein per kilogram of body weight per day, spread out over the course of the day. Protein contributes to the growth and maintenance of muscle mass. A protein shake is an easy way to supplement your diet if you’re not quite meeting your protein needs through food alone.

The most important thing is your total protein intake throughout the day. Many athletes have a shake after their workout or as a snack, but any time that makes it easier for you to reach your daily total is fine. Casein is often consumed before bed because it is released slowly.

Whey isolate typically contains very little lactose and is therefore often well tolerated. If you’re severely lactose intolerant or don’t consume dairy, choose a plant-based (vegan) protein. Not sure? Check the allergen information on the product page.

Protein can help you feel full and maintain muscle mass while following a calorie-restricted diet. A protein shake is not a meal replacement or weight-loss product in and of itself; results come primarily from a balanced diet and exercise routine. We’re happy to help you figure it out.

A pre-workout is designed to make you feel energetic and focused before your workout. The composition varies by product; on the product page, you’ll find exactly which ingredients and dosages are included.

Many pre-workouts contain caffeine; there are also caffeine-free (stimulant-free) versions. The exact amount is listed on the label. If you’re sensitive to caffeine, start with half a serving and don’t take the pre-workout too late in the day.

Generally, about 20 to 30 minutes before your workout, so the ingredients can take effect. Follow the recommended dosage on the package and do not exceed it.

Creatine is one of the most thoroughly researched supplements for athletes. A daily intake of 3 grams of creatine enhances physical performance during successive, short, and very intense efforts. It’s primarily used in strength and explosive sports.

Loading is not necessary. You can start right away with a consistent 3 to 5 grams per day; your muscles will then become saturated after a few weeks. A loading phase (for example, 20 grams per day for 5–7 days) replenishes stores more quickly, but is not required.

Breaks or cycles aren’t necessary; creatine can be used continuously at a maintenance dose. The most important thing is consistency: take it every day, even on rest days. Drink plenty of water throughout the day.

That depends on your diet and lifestyle. Common supplements include vitamin D, omega-3, and magnesium. If you eat a varied diet, you’ll get plenty of these nutrients from food; a supplement helps address specific deficiencies. If in doubt, it’s wise to discuss this with your doctor.

In the fall and winter, your skin produces little vitamin D from sunlight in our region, so supplementation is beneficial for many people. Vitamin D contributes to the normal functioning of the immune system and to the maintenance of normal bones. Follow the recommended dosage.

Both provide the omega-3 fatty acids EPA and DHA. Fish oil comes from fatty fish, while algae oil is plant-based and therefore suitable for vegans. EPA and DHA contribute to normal heart function with a daily intake of 250 mg.

Many supplements can be combined just fine, such as protein, creatine, and a vitamin. Follow the recommended dosage for each product and avoid unnecessary stacking. If you’re taking medication or have a medical condition, consult your doctor or pharmacist.

No. Supplements are meant to complement a varied diet and a healthy lifestyle, not to replace them. They are intended to address specific deficiencies or make it easier to maintain your intake (such as protein) at the right level.

Each label lists the recommended daily amount (for example, one scoop or capsule) and the number of servings per package. Follow the recommended dosage and do not exceed it, unless otherwise advised by a healthcare professional.

That depends on the product. Protein and creatine can usually be taken at any time. Some vitamins are better absorbed with a meal (such as fat-soluble vitamins). The product page and label will provide definitive information on this.

If you’re taking medication, always consult your doctor or pharmacist before adding a supplement. They can assess whether any interactions might occur. We do not provide medical advice.

During pregnancy and breastfeeding, nutritional needs are different, and caution is advised. During this time, use supplements only after consulting your doctor, midwife, or a dietitian.

When taken according to the recommended dosage, our supplements are generally well tolerated. If you do experience any symptoms, stop taking the supplement and consult a doctor if symptoms persist. Do not exceed the recommended dosage.

Part of our product line is gluten-free, but this varies by product. Always check the allergen information on the product page and the packaging, which indicates whether a product contains gluten or may contain traces of it.

Yes. We offer plant-based proteins and other vegan-friendly supplements. The product page clearly indicates whether a product is suitable for a plant-based diet.

Yes. By law, all relevant allergens are listed on the label, along with the complete list of ingredients. You can also find this information on the product page in our online store.

That varies by product. Because products are manufactured in the same facility, trace amounts may sometimes be present. The exact allergen information, including possible traces, is always listed on the label and the product page.

Many of our products contain little to no added sugars and use sweeteners. The exact nutritional information, including the sugar content per serving, can be found on each product page.

Store supplements in a cool, dry place away from direct sunlight, and reseal the package tightly after use. This will help preserve the taste, solubility, and quality for as long as possible. Keep them out of the reach of children.

THT stands for “best before.” When unopened and stored properly, the product retains its full quality until that date. Shortly after the best-before date, a product is usually still safe to consume, but the flavor or solubility may decrease slightly.

Small clumps form because protein powder absorbs moisture and are usually harmless; they often dissolve again when shaken. If the powder smells or tastes unusual, or if the packaging has been damaged, do not use it.

That’s a moisture-absorbing packet (silica gel) that keeps the powder dry during transport and storage. It’s not edible; you can throw it away after opening the container.

The powder can settle during transport, creating space at the top of the jar. The listed quantity and number of servings are correct; you’re paying for the weight, not the volume.
