Have you heard of collagen but aren\u2019t sure what it does in the body? You\u2019re in the right place. In this article, we cover the main types of collagen and what each one does.<\/p>\n\n
What is collagen?<\/h2>\n\n
Collagen is often called the body\u2019s \u201cglue.\u201d It\u2019s a key protein that adds strength and elasticity to many tissues, including skin, cartilage, and bone. The word collagen comes from the Greek \u201ckolla,\u201d meaning \u201cglue\u201d or \u201cadhesion.\u201d Collagen makes up about 30% of the body\u2019s total protein, and more than 20 types have been identified. As we age, collagen levels naturally decline, which is why different types are often discussed for different needs.<\/p>\n\n
The extracellular matrix and the role of collagen<\/h3>\n\n
To understand how collagen works, it helps to start with the extracellular matrix (ECM). The ECM is a network around connective tissue cells made up of proteins like collagen and elastin, carbohydrates, and fluid. Collagen fibers give the ECM its structure and flexibility.<\/p>\n\n
\n
Collagen fibers create a stable framework and help hold tissues together.<\/li>\n\n
Responsible for tissue strength and elasticity , skin firmness, tendon and ligament support, and cartilage cushioning all depend on collagen structure.<\/li>\n\n
Supports tissue structure and flexibility in the body\u2019s connective tissues, including skin and joints.<\/li>\n<\/ul>\n\n
Types and forms of collagen: hydrolyzed or native collagen?<\/h2>\n\n
A common question about collagen is whether hydrolyzed collagen or natural collagen is the better choice. Research suggests the two forms work differently.<\/p>\n\n
Hydrolyzed collagen: easier to mix and use<\/h3>\n\n
One of the main reasons people choose hydrolyzed collagen is that the protein chains are broken down into smaller peptides, which makes it easy to mix into drinks and use in powder or capsule form. Many formulas also include hyaluronic acid, vitamins, and minerals. Another advantage is that hydrolyzed collagen dissolves quickly in drinks, making it a practical choice any time of day.<\/p>\n\n
Native collagen: intact structure, more complex to process<\/h3>\n\n
Natural collagen keeps its triple-helix structure, which can make it less easy to mix or digest than hydrolyzed forms. It\u2019s found in foods like bone broth, aspic, and cooked meats with tendons, skin, or cartilage. Some people prefer hydrolyzed collagen supplements because they\u2019re more convenient to use.<\/p>\n\n
Different types of collagen and their roles<\/h2>\n\n
After a quick overview of the main collagen types, let\u2019s look at how the most common types help support different tissues in the body.<\/p>\n\n
Type I Collagen<\/h3>\n\n
Type I collagen is the most abundant form in the human body and is a key structural protein in skin, bones, and tendons. It is commonly found in beauty and skincare products and is often sourced from fish or cattle.<\/p>\n\n
Type II Collagen<\/h3>\n\n
Type II collagen is a major component of cartilage, joints, and the discs between vertebrae. Its hydrolyzed form is widely used in dietary supplements and is usually sourced from chicken cartilage or fish cartilage.<\/p>\n\n
Type III Collagen<\/h3>\n\n
Type III collagen helps provide structure and flexibility in tissues such as skin, blood vessels, and organs. Its hydrolyzed form is often sourced from beef connective tissue.<\/p>\n\n
Type V Collagen<\/h3>\n\n
Type V collagen is less widely known but is studied for its role in organizing collagen fibers and supporting tissue structure. In supplements, it is often sourced from eggshell membranes.<\/p>\n\n
Type X Collagen<\/h3>\n\n
Type X collagen plays a role in cartilage and bone development. It is most commonly sourced from chicken cartilage, but cartilage from cattle or fish can also be used. Research on this collagen type is still evolving.<\/p>\n\n
In brief: what does each collagen type do?<\/h2>\n\n
The different collagen types (I, II, III, V, and X) play different roles in skin, joints, bones, and the cardiovascular system. If you\u2019re considering a collagen supplement, it helps to think about which areas matter most to you and which type may fit your goals. Many supplements, especially hydrolyzed collagen products, include multiple collagen types. The table below summarizes the key information about the collagen types we\u2019ve discussed:<\/p>\n\n
