Strontium ranelate consists of a combination of strontium and ranelic acid. SrR is not approved for use in the US. Standard doses of SrR (2g) and SrC (1944mg) deliver 680mg of elemental Sr, twice the amount naturally present in the human body on a daily basis, or 170-340 times the naturally occurring strontium levels in the human diet per day.
