Protein plays a crucial role in supporting the skeletal system, and its importance is well established by scientific research. Proteins are fundamental building blocks of all tissues, including bone. Approximately one-third of bone mass is composed of organic components, of which collagen (a protein) is predominant. Collagen fibers form a matrix that provides bone with tensile strength and flexibility, supporting the deposition of mineral crystals such as calcium phosphate, which give bones their hardness and rigidity.

Scientific studies have shown that adequate dietary protein is essential for optimal bone health across the lifespan. Protein intake stimulates the production of insulin-like growth factor 1 (IGF-1), a hormone that promotes bone formation and remodeling. Numerous clinical and epidemiological studies have demonstrated that insufficient protein intake is associated with decreased bone mineral density, increased risk of fractures, and impaired bone healing. Conversely, sufficient or higher protein consumption, especially in older adults, has been linked with improved bone mass and reduced fracture risk, particularly when calcium intake is also adequate (source).

Concerns that high protein intake might lead to bone loss due to increased calcium excretion have not been supported by more recent research. In summary, protein is scientifically validated as essential for bone structure, maintenance, and repair, justifying its role in supporting the skeletal system.
