Synopsis

Source of validity: Scientific
Rating (out of 5): 2

Bovine-derived supplements, particularly bovine bone extract and bovine-derived collagen, are sometimes used to support bone health and are marketed for osteoporosis prevention or treatment. The scientific rationale is that these products provide minerals (especially calcium and phosphorus) and collagen proteins, which are essential components of human bone. Some clinical studies have examined the effects of bovine bone hydroxyapatite (microcrystalline hydroxyapatite complex, or MCHC) supplementation on bone mineral density (BMD). Results from small, short-term trials suggest that MCHC may have a modest effect on slowing bone loss compared to calcium carbonate or placebo, but the quality of evidence is limited by sample size, study duration, and methodological concerns. Systematic reviews generally conclude that while bovine-derived bone minerals can increase calcium intake, robust evidence demonstrating a significant reduction in fracture risk or superiority over standard calcium/vitamin D supplementation is lacking.

Bovine collagen peptides are also promoted for bone health, as collagen is the main protein in bone matrix. Some animal and preliminary human studies suggest that collagen supplementation may improve bone metabolism or slightly increase BMD, but large-scale, long-term human trials are still needed. There are no major clinical guidelines that recommend bovine-derived products as a first-line therapy for osteoporosis, and their use is considered adjunctive at best. Overall, while there is some scientific interest and limited evidence, the data supporting the efficacy of bovine-derived supplements for osteoporosis is weak to moderate (hence a rating of 2).
