I expect you have all heard the Word:  calcium and vitamin D supplements do not protect older women against osteoporosis.

Well certainly just standing near the supplement bottles isn't going to do it.   It appears that seven years into the study, only 59% of the participants were actually taking their doses. 

When you adjust for this fact, among fully compliant study members, the risk of hip fracture dropped by nearly 30%. 

Now, THAT's statistically significant.
