prevention of osteoporosis
"I noticed joint aches with this medication (and also from concommitant Femara, an anti-estrogen drug).  Taking Glucosamin/Condroitin (1000/600 per day) solved the problem.  When I stop the G/C, the aches come back.  The only downside to this medicine for me is forgetting to take it once per week - or accidentally ingesting food beforehand, so I couldn't take it that day."
