Collagen is a protein made up of three intertwined strands that form a stable triple-helix structure, which gives it strength and stability. This structural arrangement is important because it allows collagen to provide support and firmness to tissues throughout the body.

Collagen () is the main structural protein in the extracellular matrix of the connective tissues of many animals. It is the most abundant protein in mammals, making up 25% to 35% of protein content. Amino acids are bound together to form a triple helix of elongated fibril known as a collagen helix. It is mostly found in cartilage, bones, tendons, ligaments, and skin. Vitamin C is vital for collagen synthesis.
