New drug protelos (strontium ranelate) for osteoporosis just been announced.
Key in strontium ranelate and also strontium citrate into an internet search engine, very interesting research data for the treatment of oesteoporosis going back to the fifties (when it was first used to treat the disease).
It appears the ranelate is the drug version of strontium (the only way they could patent it) and is derived from strontium which is a mineral and available to buy as strontium citrate (not classed as a drug).
My mum has osteoporosis aged 76, late diagnosis, so most of damage already done, but strontium does appear to have remarkable results both the ranelate version (clinically trialled as they could class it as a drug) and the citrate version (not clincally trialled but very good results). Print off the data on the internet. Worth taking this supplement (strontium citrate) if you have a family history of oesteoporosis and are nearing the menopause or even if you have the disease, supposed to stop you from developing oesteoporosis.
