Collagen: The Body’s Primary Structural Protein
Collagen is the most abundant protein in the human body, comprising approximately 30% of total body protein. It forms the fundamental structural framework of connective tissues, including skin, cartilage, tendons, ligaments, bones, and the extracellular matrix
At a microscopic level, collagen fibres resemble a tightly wound rope, which explains their remarkable tensile strength. Individual collagen fibrils bundle together to form microfibrils, which further assemble into macrofibrils and ultimately into strong collagen fibres. This layered structure allows collagen to resist stretching and provide stability to tissues under mechanical stress

Role in Connective Tissue
Collagen is a critical component of connective tissue — the “glue” that supports and binds tissues throughout the body. Connective tissue provides cushioning, hydration, and mechanical strength through an extensive extracellular matrix composed primarily of collagen, elastin, and reticular fibres. Tissues richest in collagen include:

• Tendons and ligaments — providing tensile strength and flexibility
• Dermis of the skin — supporting skin structure, elasticity, and firmness
• Cartilage and bone — contributing to joint cushioning, mobility, and skeletal stability.

Amino Acid Composition
The amino acid and peptide compositions of dietary collagens closely mirror those of human collagens, making dietary collagen peptides well suited to support collagen turnover and renewal. Collagen proteins have a unique amino acid profile, characterised by:
Hydroxyproline (~12%) — a hallmark of collagen that plays a critical role in triple-helix stability.
Glycine (~22%) and Proline (~13%) — abundant structural amino acids essential for collagen’s characteristic configuration
While other dietary proteins can contribute these amino acids, collagen is a particularly concentrated and targeted source.
