Source of validity: Scientific
Rating (out of 5): 3

Chicken collagen, particularly Type II collagen derived from chicken sternum, has been investigated for its potential benefits in supporting the skeletal system, especially joint health—a vital component of the overall skeletal system. Several clinical studies suggest that oral supplementation with undenatured type II chicken collagen (UC-II) can help improve symptoms of osteoarthritis and rheumatoid arthritis, primarily by reducing joint pain, stiffness, and improving mobility. The proposed mechanism is through immune modulation and promoting cartilage integrity rather than directly increasing bone density.

However, studies specifically evaluating chicken collagen's direct effect on bone density or bone strength are limited. Most available evidence focuses on joint health rather than bone tissue itself. The rationale for its use in skeletal support largely stems from its effect on cartilage, which is a connective tissue within joints but not the primary component of bone. While some animal studies suggest possible benefits for bone metabolism, robust human clinical evidence is lacking.

In summary, chicken collagen is scientifically validated for supporting joint health, a component of the skeletal system, but evidence for direct benefits to bone structure is not strong. The overall evidence rating of 3 reflects moderate support based on joint health studies, with less conclusive evidence for bone-specific outcomes.
