Supplement
Strontium Citrate
SaveStrontium citrate is a supplement form of strontium used for bone health. It incorporates into bone matrix and may influence bone metabolism markers.
Quick verdict
Prescription strontium ranelate has fracture data; OTC strontium citrate lacks equivalent evidence but may still benefit bone density markers.
Evidence score
A rough internal score reflecting quantity, quality, and consistency of human evidence. Not a clinical recommendation.
What the research shows
Strontium ranelate (prescription) has RCT data showing fracture reduction, but was withdrawn in some markets due to cardiovascular concerns. Strontium citrate (OTC) lacks comparable clinical trial data. DXA scans overestimate bone density with strontium use.
Benefits
- May support bone density markers
- Incorporates into bone mineral matrix
- Used as adjunct to calcium and vitamin D
Dosage notes
680 mg elemental strontium daily, taken at bedtime away from calcium.
Side effects
- GI discomfort
- Potential cardiovascular concerns (from ranelate data)
- Falsely elevated DXA readings
Who should be cautious
May increase cardiovascular risk based on ranelate data. DXA scans are artificially inflated by strontium incorporation. Separate from calcium by 4+ hours.
What this page cannot tell you
OTC strontium citrate cannot be assumed equivalent to prescription strontium ranelate. Bone density improvements on DXA may be partly artifact.
