Discover our solutions to support your progress through targeted nutrition. At Nutrition Outlet, we select products designed to support your training, your recovery, and your physical goals.

Protein, creatine, gainer: supplements to support mass gain

To build muscle mass, a sufficient calorie intake is generally required. Choosing the right products helps support both an increase in energy intake and strength training. The types of supplements covered in this section fit into a calorie-rich diet.

Protein (whey, casein, isolate)

Protein contributes to the growth of muscle mass and to the maintenance of normal muscle mass.* It fits into every meal or snack to cover your protein needs based on your training. Whey is characterized by fast absorption, casein by a more gradual absorption; the choice depends on your schedule and preferences.

Creatine monohydrate

Creatine increases physical performance in successive bursts of short-term, high-intensity exercise, in adults engaging in high-intensity exercise.* This effect is obtained with a daily intake of 3 g of creatine. A quality creatine fits easily into a strength program.

Weight gainer

A gainer is a supplement formulated to help increase daily calorie intake. It combines protein and carbohydrates for a convenient, easy-to-dose energy surplus. Protein contributes to the growth and maintenance of muscle mass;* carbohydrates provide a source of energy. A gainer suits athletes whose diet alone doesn't provide enough calories, particularly with a fast metabolism.

Carbohydrate and fat sources

Complex carbohydrates (maltodextrin) or fats (such as coconut oil) can be added to the program to increase total calorie intake and maintain an energy intake suited to training. Meal replacements, often made up of carbohydrates and protein, are a convenient option for supplementing meals and reaching your calorie goals.

BCAAs and EAAs (amino acids)

Branched-chain amino acids (BCAAs) and essential amino acids (EAAs) are supplements commonly used in sports nutrition, during or between sessions, to supplement daily protein intake.

Our tips for reaching your weight and muscle-building goals

Building mass takes method. A calorie-rich diet spread across several intakes a day, combined with suitable supplements and a regular training program, forms the foundation. Rest days and enough sleep are a full part of progress.

1. Favour quality calories

Gaining weight requires consuming more calories than you burn, while paying attention to the quality of your intake:

• Rely on complex carbohydrates (oats, sweet potatoes, brown rice) to provide the energy your training needs.
• Include good-quality protein, such as whey or plant-based protein blends, to support strength training.

2. Adopt suitable supplements

Combine several types of products according to your needs: protein, carbohydrates, and creatine, timing your intake around your training sessions:

• before training: carbohydrate sources;
• after training: protein to support recovery;
• as a snack: gainers or whey for a regular nutritional intake.

3. Split your meals and snacks

Spread your calorie intake across the day. Consider including:

• calorie-rich shakes between meals;
• protein-rich snacks such as bars or nuts;
• a post-workout intake combining carbohydrates and protein.

4. Vary your training sessions

Combine strength exercises and longer sets with moderate load, to engage the muscle in different ways:

• Compound exercises engage several muscle groups: squat, deadlift, bench press, pull-ups, barbell row.
• Isolation exercises target specific muscles: bicep curl, cable tricep extension, lateral raises, leg curl, crunch.
• Gradually increase the load: when 12 reps become easy, adjust the weight or sets to keep progressing.
• Dumbbell and barbell work also engages the stabilizing muscles: dumbbell press, lunges, clean and jerk.
• Include light to moderate cardio (brisk walking, cycling) to maintain overall balance.

5. Plan for optimal recovery

Rest and recovery matter as much as training:

• Get enough sleep to give your body time to recover.
• Space out intense sessions and respect your rest days.
