I was dx with osteopenia a month before I started treatment for C and began taking
fosamax weekly - the low dose 35 mg per week. Before tx for C my hip T score was -1.7. After treatment my T score was -1.3, so it did improve. The lumbar spine T score imporved during that time too. I continued to take the fosamax thoughout my tx and did not clear the virus, so would surmise the improvement was from the fosamax and not anything else.
