Bovine protein, particularly in the form of hydrolyzed collagen or bone broth protein, has a scientific basis for its use in supporting the skeletal system. Collagen is the most abundant protein in the human body, constituting a major component of bone matrix. Several clinical studies have investigated the effects of bovine-derived collagen supplements on bone health. For example, some randomized controlled trials indicate that collagen peptides may help improve bone mineral density and markers of bone formation, especially in postmenopausal women who are at higher risk of osteoporosis. The proposed mechanism is that collagen peptides provide amino acids and bioactive peptides that stimulate osteoblast activity (bone-forming cells) and enhance the synthesis of bone extracellular matrix.

However, while there is promising evidence, the overall quality of the studies is moderate, with some limitations in sample size and study duration. Additionally, collagen is not the only nutrient required for bone health; adequate calcium, vitamin D, and other micronutrients are also necessary. Therefore, while scientific evidence exists, it does not yet warrant a very high rating. The use of bovine protein to support bone health is justified scientifically, particularly for collagen forms, but should be considered as part of a broader nutritional approach.
