One more study that shows that milk may help you grow taller

 

“Bone is constantly balanced between the formation of new bone by osteoblasts and the absorption of old bone by osteoclasts. To promote bone growth and improve bone health, it is necessary to promote the proliferation and differentiation of osteoblasts. Although bovine milk is known to exert a beneficial effect on bone formation, the study on the effect of bovine milk extracellular vesicles (EVs) on osteogenesis in osteoblasts is limited. In this study, we demonstrated that bovine milk EVs promoted the proliferation of human osteogenic Saos‐2 cells by increasing the expression of cell cycle‐related proteins. In addition, bovine milk EVs also induced the differentiation of Saos‐2 cells by increasing the expression of RUNX2 and Osterix which are key transcription factors for osteoblast differentiation. Oral administration of milk EVs did not cause toxicity in Sprague‐Dawley rats. Furthermore, milk EVs promoted longitudinal bone growth and increased the bone mineral density of the tibia. Our findings suggest that milk EVs could be a safe and powerful applicant for enhancing osteogenesis.”
