There appears to be little benefit of increasing protein intake for bone health in healthy adults but there is also clearly no indication of any detrimental effect , at least within the protein intakes of the population s studied ( around 0.8–1.3 g/Kg/day ) .
We undertook a systematic review and meta- analysis of published papers assessing  dietary protein and bone health .

Milk Basic Protein Promotes Bone Formation and Suppresses Bone Resorption in Healthy Adult Men
Milk contains several components effective for bone health . In the previous in vitro and in vivo studies , we have shown that milk whey protein , especially its basic protein fraction ( milk basic protein [ MBP ] ) , promoted bone formation and suppressed bone resorption . This present study examines the effect of MBP on the biochemical markers of bone metabolism in healthy adult men .  Experimental beverages containing MBP ( 300 mg of MBP a day ) were given to 30 normal healthy adult men for 16 days . The serum osteocalcin concentration had increased significantly after 16 days of ingesting the experimental beverage containing MBP .  Urinary cross-linked N-teleopeptides of type-I collagen ( NTx ) excretion had decreased significantly after 16 days of ingesting MBP . The urinary NTx excretion was related to the serum osteocalcin concentration after 16 days of ingestion . These results suggest that MBP promoted bone formation and suppressed bone resorption , while maintaining the balance of bone remodeling
