Collagen is the most abundant protein in the human body, making up about 30% of total protein content. It acts as the main structural protein found in skin, bones, muscles, tendons, and connective tissues.
Key functions include:
- Providing structure and strength to skin
- Supporting joint health and flexibility
- Maintaining bone density
- Helping wound healing
According to research, our natural collagen production decreases by about 1% per year after age 20, which can lead to visible signs of aging and reduced joint flexibility.
