Multi-collagen is a dietary supplement that contains a blend of collagen sourced from various natural sources, such as bovine (cow), marine (fish), and chicken collagen. Collagen is a protein found in the body's connective tissues, skin, hair, nails, and bones, and it provides structural support and elasticity. Multi-collagen supplements aim to provide a diverse range of collagen types, including type I, II, and III, which may offer additional benefits for skin health, joint support, and overall wellness. These supplements are often taken to promote healthy aging, improve skin elasticity, strengthen hair and nails, and support joint function.
