Hi there. I have had osteoporosis for a number of years now. Saveourbones was recommended to me by a consultants wife, after a devastating appointment. I have not bought the e-books but I HAVE received regular emails. They contain helpful and informative info, exercises and recipes. Yes, Saveourbones has advertised their books (I've even considered purchasing some of them and still might), but there is no hard sell. Over the years I have found them supportive and its comforting to know that I am not the only soul who resists the rheumatolagists threats of doom and gloom if I don't take his medication. I am 73, don't work and have no bias toward this company. I just speak as I find.
