I am now age 66 and doing quite well. There are various degrees of osteoporosis. The nutrients magnesium and calcium hydroxyappetite which have been proved to be the best calcium to rebuild bones and Iprislavones. A synthetic isoflavone that has been proven to be as good is Fosamax and does not have any of the side effects of the medications such as esophigasitus. Oviously smoking cessation and alcohol reduction helps.
Magnesium helps rebuild bones.
I recommend yoga to strengthen the bones. When the liver is toxic in most of us by the time we reach menopause, the progesterone might become an adrenal hormone. This is something that we don't want it to become. This is one reason I use mostly transdermal creams or gels and suppositories for progesterone. It is necessary, therefore, to do a detoxification program periodically, especially for people who live in toxic environments, such as New York, where they're now using the very toxic nerve gas, Malathion.
