Bovine protein, particularly in the form of collagen peptides or hydrolyzed collagen derived from cattle, has been studied for its potential role in supporting bone health and possibly helping in the management or prevention of osteoporosis. Scientific evidence suggests that dietary protein is important for bone structure, as it provides amino acids necessary for collagen synthesis and bone matrix formation. Several clinical studies and reviews have indicated that collagen supplementation, including bovine-derived forms, may have beneficial effects on bone mineral density (BMD) and bone turnover markers, especially in postmenopausal women who are at higher risk for osteoporosis.

For example, a randomized controlled trial published in Nutrition Journal (2018) showed that daily supplementation with specific bioactive collagen peptides improved BMD in postmenopausal women. The postulated mechanisms include stimulation of osteoblast activity and increased synthesis of bone collagen matrix. However, the overall body of evidence is still emerging and not universally conclusive, with some studies showing modest or no effects. Major health organizations continue to emphasize adequate overall dietary protein and calcium intake, rather than specific bovine protein supplements, for bone health.

In summary, there is scientific rationale and some supportive clinical evidence for the use of bovine protein (mainly in collagen form) to support bone health and potentially reduce osteoporosis risk, but the evidence is moderate (rated 3/5) and should be interpreted with caution until larger, long-term studies are available.
