In 2004 I was 51 turning 52 at the very end of the year:
Firstly, my numbers
2004 Femoral Neck -2.8
2019 Femoral Neck -.6

I tried Doctor prescribed meds in 2004. I did not feel that I could live with the side effects.
I stopped the meds; I did lots of research and had some more tests run to ck my hormones.

I began a regime of:
Bioidentical Hormones
Strontium Citrate at night
Ez Orb Calcium in the morning; there are generic forms of this now available which are cheaper

Plus:
All the usual suspects of good health were taken or cked...vit d, k, weight bearing and jarring exercise etc
Melatonin a small amount at night to sleep, I mention because a study has shown it to be helpful to encourage the body to grow bone.

I have had no known fractures and no side effects since beginning strontium citrate or this regime.
