In January 06 my bone density went from -1.2 to -1.4 and my doctor said I have osteopenia and should start Fosamax. I was taking calcium citrate and decided no way was I taking Fosamax. I researched Ezorb and started taking the maintenance dosage. In January 08 my numbers were -0.9 spine and -0.8 femmer. I just had another DEXA scan and my numbers were exactly the same (0.9 spine and -0.8 femmer). I walk 30 min. every day and take 800 iu of vitamin D3. I will keep on with Ezorb and check again in 5 years. Hope this helps everyone who has any doubts about Ezorb. All I know is it works great for me at age 74.
