The composition of a healthy human body follows strict scientific proportions, sustained primarily by water and essential nutrients:
- Water: Accounts for 60% of total body weight, serving as the fundamental environment for metabolism and circulation.
- Protein: Accounts for 18% of total body weight, acting as the core material for building body cells and tissues.
- Collagen: Within that 18% of protein, as much as 40% is collagen (which equals approximately 7.2% of total body weight).
This data demonstrates that collagen is not merely a cosmetic or beauty supplement, but rather a critical core structure that supports the entire protein machine.
