the improvement of bone at femoral neck was more pronounced in the peri PBM population (20 - 35 years) than the pre PBM population (<20 years).Conclusion: Our findings provided novel insights and evidence in calcium supplementation, which showed that calcium supplementation significantly improves bone mass, implying that preventive calcium supplementation before or around achieving PBM may be a shift in the window of intervention for osteoporosis.
