Protein Powder: Which Protein Should You Choose for Recovery and Performance?

Protein powders are among the most widely used supplements in the sports world, renowned for supporting muscle recovery and gaining or maintaining lean mass. Whey, isolate, casein, plant-based proteins: how to choose according to your goals?

Why take protein after exercise?

Exercise causes muscle micro-tears. Consuming protein after exercise contributes to muscle protein synthesis (MPS) and recovery ^[1].

How much protein per day?

According to literature (EFSA, ISSN):

• Endurance athletes: approximately 1.2 to 1.6 g/kg/day
• Strength and bodybuilding sports: approximately 1.6 to 2.2 g/kg/day ^[5]

Protein powders make it easy to meet these intake requirements.

Different types of protein powders

Whey (lactoserum)

• Milk-derived protein, fast assimilation
• Rich in leucine, a key amino acid for stimulating MPS ^[7]

Whey isolate

• Filtered version: higher protein content, less lactose
• Suitable for people sensitive to lactose

Casein

• Slow-digesting protein, often taken before bed

Plant-based proteins

• Peas, rice, hemp, soy…
• Suitable for vegetarians and vegans; pea+rice blends complete amino acid profiles ^[8]

Protein quality: what to check?

• Protein content (%) on the label
• Essential amino acid profile (especially leucine)
• Absence of added sugars or controversial sweeteners
• Anti-doping certification if applicable (Informed-Sport, etc.)

Products available on Pharmaplusfrance.store

Conclusion

Protein powders are a practical tool to support recovery and daily protein intake. The choice depends on your goal, digestive tolerance, and dietary preferences.
