Understanding Protein Needs

Why Protein Matters

Protein is essential for building and repairing tissues, making enzymes and hormones, and supporting immune function.

Individual Needs

Protein requirements vary based on body size, activity level, age, health status, and fitness goals.

Timing Matters

Distributing protein intake throughout the day (every 3-4 hours) is more effective than consuming it all at once.

Quality Counts

Complete proteins contain all essential amino acids. Plant proteins can be combined to provide complete protein.
