Hi @tiny28 I read that for post menopausal women, HRT could help slow bone loss rather than actively "build" bones. Some clinical studies in the past had showed that on average, a bmd increase of 2-5% is typical over a period of 1-2 years with lumbar spine seen the most gains. I didnt come across fracture reduction data or long term study results. The gain in bmd can vary depending on type of HRT, dosage, duration of therapy, age at the start of therapy and individual health profile.

I started HRT at 61, 11 years past menopause as a follow-up after Forteo therapy. My bone markers showed bone resorption (or bone breakdown) was dramatically reduced after 3-6mo on HRT and bone formation marker followed the same fate.
