I have decided definitely not to take Alendronate (fosomax) or any of the Bone "strengthening" prescriptions. That being said I am wondering if anyone out there saw an improvement in Dexa scan with the above mentioned vitamins. I am beginning weight lifting (tiny weights) and have always walked a lot. I am taking 1500 Cal. with Magnesium and Vit D plus 100 K2 daily. Thoughts? Advice? Anyone see improvements in bones? Thanks!
