Collagen is a fundamental protein, constituting approximately one-third of the body's total protein content. It is a fibrous protein characterized by its triple-helix structure, which imparts remarkable tensile strength to tissues. Primarily found in the extracellular matrix, collagen is vital for the structural integrity of skin, providing firmness and elasticity; in bones, contributing to their strength; and in cartilage, tendons, and ligaments, ensuring flexibility and resilience. The body naturally produces collagen, but synthesis begins to decline around the mid-20s, accelerating with age, exposure to UV radiation, smoking, and poor diet. This reduction in collagen leads to common signs of aging, such as wrinkles, sagging skin, brittle nails, thinning hair, and joint discomfort. Supplementation aims to counteract these effects by providing the necessary building blocks for the body's own collagen production. There are at least 28 different types of collagen, but types I, II, and III are the most prevalent. Type I is abundant in skin, bones, tendons, and ligaments; Type II is primarily found in cartilage; and Type III is common in skin, blood vessels, and internal organs. The specific type of collagen in a supplement often dictates its targeted benefits, though many supplements offer a blend to support overall connective tissue health.
