There are at least 28 types of collagen in the human body, but the most important ones for health and beauty are Types I, II, and III.
- Type I – The most abundant type. It supports skin, bones, tendons, and ligaments. Helps keep your skin firm and youthful.
- Type II – Found in cartilage. Supports joint health and flexibility.
- Type III – Works alongside Type I to support skin, organs, and blood vessels.
Most collagen supplements on the market are made from a mix of Type I and III. If you’re focusing on joint health, look for supplements with Type II collagen.
