Proteins are the body’s structural macronutrients. Composed of amino acids, they play a role in muscle growth, cell regeneration, and the production of enzymes and antibodies. An adequate intake is essential for athletes, seniors, vegetarians, and anyone looking to maintain muscle mass. Discover our high-protein diet line.
What is a protein, and what is its role?
Proteins are chains ofamino acids linked by peptide bonds. The body uses 20 of these, including 9 essential amino acids that it cannot synthesize on its own. They perform multiple biological functions: muscle and skin structure (keratin, collagen), transport (hemoglobin, albumin), signaling (peptide hormones), defense (antibodies), and catalysis (digestive and metabolic enzymes). Proteins contribute to the growth and maintenance of muscle mass—EFSA-approved claim.
What are the benefits of protein for athletes?
Protein is the essential nutrient for recovery and athletic performance.
- Contribute to the growth and maintenance of muscle mass (EFSA-approved claim)
- Repairs micro-tears in muscle tissue and reduces post-workout muscle soreness
- Optimal intake: 1.6 to 2.2 g per kilogram of body weight for athletes during periods of intense training
- Timing: anabolic window within 2 hours after exercise—see our sports recovery line
- Combine with BCAAs and creatine to optimize protein synthesis
Animal vs. Plant Proteins: What Are the Differences?
Both sources are complementary and have distinct nutritional profiles.
- Animal proteins (whey, meat, eggs, fish): complete profile of essential amino acids, high biological value—ideal for muscle recovery
- Plant-based proteins: peas, rice, hemp, quinoa, soy—often limited in one or more essential amino acids, to be supplemented through food combinations (legumes + grains)
- The 100% plant-based protein line is suitable for vegetarian and vegan diets
- Plant-based proteins generally have slightly lower digestibility—choose hydrolyzed formulas for better absorption
Protein and weight management?
Protein contributes to body weight management through two main mechanisms.
- Long-lasting satiety: they stimulate satiety hormones (GLP-1, PYY) and reduce cravings
- Preserves muscle mass during low-calorie diets—by preventing catabolism
- Recommended intake during a cutting phase: 2 to 2.5 g/kg to maintain lean body mass
How do you choose a protein supplement?
The choice depends on your goal, digestive tolerance, and diet.
- Whey concentrate/isolate: fast digestion, ideal post-workout, complete amino acid profile
- Casein: slow digestion, ideal before bed for nighttime recovery
- Pea + rice: complementary plant-based combination providing all 9 essential amino acids
- Quality criteria: no artificial sweeteners, GMP-certified, traceable raw materials
- Protein can be combined with glutamine formulas for additional digestive support
Protein and specific populations?
Protein requirements vary depending on individual profiles and physiological conditions.
- Seniors: Sarcopenia (age-related muscle loss) requires a higher protein intake—at least 1.2 to 1.6 g/kg
- Vegetarians/vegans: combine legumes and grains at every meal and consider supplementing with plant-based protein
- Kidney failure: Reduce protein intake under strict medical supervision
- Pregnancy and breastfeeding: increased needs—+15 to 25 g/day depending on the trimester—to be met primarily through diet
