Collagen is the main structural protein of connective tissues in the body, including cartilage, bone, tendons, and ligaments. The types of collagen commonly studied in the context of joint health include collagen type II (the main component of joint cartilage) and hydrolyzed collagen.
Derivation
Main structural protein of connective tissue (cartilage, bone, tendons, ligaments).
Collagen type II (main in joint cartilage).
According to research, collagen has the following effects:
Supports cartilage: Provides building blocks, maintains and regenerates cartilage.
Reduces pain, joint stiffness: Collagen peptides may stimulate collagen production, reduce mild inflammation, and increase joint flexibility.
Scientific research sources:
Overview: Collagen peptides stimulate collagen production (PubMed: 30681787).
Cartilage protection: Collagen peptides stimulate cartilage cells to produce extracellular matrix (ScienceDirect: 10.1016/j.joca.2011.05.004)."
Hydrolyzed collagen (small, easily absorbed peptides).
