Hi @echolsleslie, Here is a link to a scientific article about nutrients essential for bone health:

I hope you can access it through the link. If not, google the title,

Essential Nutrients for Bone Health and a Review of their Availability in the Average North American Diet

I take alendronate once a week in addition to Calcium, Magnesium, Vitamin D, K1, and L. Reuteri. I will be adding boron, and after reading this article, probably silica. I also do strength training exercises for osteoporosis three times a week (Carol Michaels is the instructor - she's on Youtube), walk about three hours a week, and started Whole Body Vibration Therapy to try and build back bone density. I am on prednisone for an autoimmune disorder. Before I got the autoimmune disorder about 18 months ago, I was very active, even doing Judo, so was shocked when I learned I had osteoporosis, but it runs in my family. Good luck to you!
