Building Resilient Tissue: Nutrients and Cofactors in Collagen Deposition, Synthesis, and Repair

Collagen is the most abundant protein in the human body, serving as a critical component of connective tissue, including skin, tendons, ligaments, cartilage, and bone. Its strength and elasticity support structural integrity and play an essential role in tissue repair. Understanding the nutrients and cofactors that drive collagen production can empower us to optimize healing and maintain healthy tissues.

The Collagen Lifecycle: Synthesis and Repair

Collagen synthesis begins with procollagen production in fibroblasts. Procollagen undergoes hydroxylation, glycosylation, and other post-translational modifications before being secreted into the extracellular matrix (ECM), where it assembles into mature fibrils. This complex process is energy-intensive and relies on specific nutrients and cofactors to ensure its success. Tissue repair requires sufficient collagen deposition to rebuild damaged areas, and deficiencies in these essential elements can delay or impair healing.
