I have read several books about Osteoporosis, read dozens of information from my google searches and listened to multiple podcasts. The most informative and BEST book IMO is “Great Bones” by Keith McCormick. He doesn’t scare you like others do, but educates you about various causes, delves into what is happening at the cellular level, explains how the medicines work. He is a chiropractor doctor who also had osteoporosis, went on medication for a while, but also believes that proper nutrition, supplements, and exercise are a big help. I got mine on Amazon.
