May support bone health (label use) Fairly consistent evidence
Health Canada notes strontium in various salt forms can be used to help support bone health.[1]
SUPPLEMENT EXPLAINER · OTHER INGREDIENT
Strontium
Strontium is a naturally occurring mineral sold in Canada in OTC natural health products (citrate, lactate, gluconate and other salts) and can be used to help support bone health. EMA found 680 mg/day strontium ranelate beneficial for severe osteoporosis but not for people with pre-existing heart or circulatory problems. Health Canada found no CV-risk data for lower ranelate doses or other salts, yet takes a precautionary approach: products providing adults more than 4 mg elemental strontium per day should warn people with heart disease, circulatory problems, or blood-clot risk not to use them.[1]
Based on: Health Canada. Checked 2026-11-04; 1 sources.
To be clear: bone-health wording reflects Canadian product context, but cardiovascular safety remains uncertain; this page mainly relays Health Canada’s 2015 precautionary safety review—not a recommendation to take strontium.

What it can do
Each card shows how strong the evidence is. Greener means more consistent research.
Fairly consistent evidenceEarly or limited effectInconsistent or too little evidence
CV risk: precautionary label limits Early or limited effect
EMA: 680 mg/day ranelate should not be used with pre-existing heart or circulatory problems. Canada lacks data for other salts/lower doses but still requires >4 mg elemental strontium/day products to warn high-risk users not to use them.[1]
Supplement salts ≠ EU prescription ranelate Inconsistent or too little evidence
Strontium is the active component; salt partners help absorption. There is not enough information to compare absorption or CV risk across salt forms.[1]
Bottom line: Canadian strontium products may claim bone-health support, but CV risk remains uncertain; people with heart disease, circulatory problems, or blood-clot risk should not use products providing more than 4 mg elemental strontium per day under Health Canada’s precautionary labelling.[1]

Products providing adults more than 4 mg elemental strontium per day must update labelling: do not use if you have or are at high risk for heart disease, circulatory problems, or blood clots[1]
680mg
EMA review prescription dose of strontium ranelate 680 mg per day (not a general supplement recommendation)[1]
682mg
Licensed Canadian products then ranged about 4 mg up to 682 mg elemental strontium daily[1]

Safety
Take care if
- If you have or are at high risk for heart disease, circulatory problems, or blood clots: under precautionary labelling, do not use products providing more than 4 mg elemental strontium per day.[1]
- Health Canada considers that strontium, regardless of form, may have a potential risk of cardiovascular side effects in people who are already at risk.[1]

How to use it
How to read dose
Read elemental strontium milligrams on the label, not the salt’s total weight; Europe’s 680 mg ranelate figure is a prescription dose, not a typical supplement directions line.[1]
