HelloPharmacist Scorecard of Ionic Strontium 100 mg by Trace Minerals Research
Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.
What’s inside
Full disclosure
This liquid supplement contains 4 active ingredients: strontium (100 mg per serving), magnesium, Ionic Trace Minerals (a blend we cannot fully detail), and chloride. The product also includes purified water, potassium sorbate (a preservative), and citric acid as inactive ingredients.
Strontium is a mineral that may support bone density and tooth sensitivity. Magnesium is essential for muscle and nerve function, energy production, and bone health.
The exact amounts of magnesium and the trace minerals aren't specified on the facts provided.
Does it work?
Strong evidence
Strontium has established evidence for dental hypersensitivity and painful bone tumors (bony metastases), and is likely effective for osteoporosis. It's possibly effective for osteoarthritis and prostate cancer.
Magnesium is effective for indigestion and constipation, and for treating magnesium deficiency and preventing pre-eclampsia in pregnancy. We hold no effectiveness data in our records for the Ionic Trace Minerals blend or chloride in this product.
How safe is it?
Well-documented data
Strontium — especially the ranelate form — carries warnings about serious heart and blood clotting risks. It's not safe to use during pregnancy, and should be avoided while breastfeeding.
The most common side effects are atopic dermatitis, diarrhea, headache, and nausea. Rare but serious adverse effects include heart attack, bone weakening (osteomalacia), and blood clots in the lungs or veins; research shows strontium ranelate increases clotting risk by roughly 50% and heart attack risk by 1.6-fold in people with osteoporosis.
Magnesium is generally well tolerated at recommended doses. The most common side effects are diarrhea, nausea, and vomiting.
Magnesium is needed during pregnancy but only take supplements under your doctor's guidance. Normal dietary amounts are fine while breastfeeding, but check with your doctor before using supplements.
We have no safety data on file for Ionic Trace Minerals or chloride.
Meds to double-check
Major interaction found
Check with your doctor or pharmacist before taking this product if you use levodopa/carbidopa (Parkinson's disease), estrogens or androgens (hormone therapies), quinolone or tetracycline antibiotics, antacids, calcium channel blockers, skeletal muscle relaxants, potassium-sparing diuretics, sulfonylureas (diabetes drugs), or bisphosphonates (osteoporosis drugs). Magnesium can dangerously lower blood sugar with certain diabetes medications and can block antibiotic absorption.
Strontium may reduce how your body clears it if you're on hormones, raising the risk of side effects.
The bottom line
Scorecard at a glanceFully disclosed formula with clinical evidence supporting its stated purpose. Major medication interactions have been identified, and safety information is well characterized.
This product may help with bone density, tooth sensitivity, or constipation, but strontium carries real cardiovascular risks — especially if you have osteoporosis. The magnesium and strontium interact with multiple medication types, from antibiotics to diabetes drugs to Parkinson's medications.
Talk with your own doctor or pharmacist before starting it, especially if you take any prescription drugs or have a history of blood clots or heart disease.

Ionic Strontium 100 mg by Trace Minerals Research Drug Interactions
HelloPharmacist Interaction Report
Ionic Strontium 100 mg by Trace Minerals Research can interact with medications through its strontium and magnesium content.
The most serious interaction is with levodopa/carbidopa (used for Parkinson's disease): magnesium can reduce levodopa levels by up to 35%, significantly weakening the drug's effect.
Read the full breakdown — every affected drug type, severity by severity
Strontium moderately interacts with estrogens and androgens — these hormones may reduce how your body clears strontium, potentially raising its levels and side effects. Strontium also interferes with several antibiotics: quinolone and tetracycline antibiotics may lose effectiveness if taken at the same time, since strontium binds them in your stomach.
Antacids have the same effect on strontium absorption itself, cutting it by 20–70%.
Magnesium in this product moderately interacts with calcium channel blockers (blood pressure drugs), skeletal muscle relaxants, potassium-sparing diuretics, sulfonylureas (diabetes medications — magnesium can cause dangerously low blood sugar), quinolone antibiotics, and bisphosphonates (osteoporosis drugs). Magnesium also reduces the effectiveness of acid-reducing medications when you need a laxative effect.
We could not check Ionic Trace Minerals or Chloride — we hold no interaction data for them. Altogether, these interactions span 338 individual medications.

For each ingredient in Ionic Strontium 100 mg with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.
Magnesium
Levodopa/Carbidopa (Sinemet)
Magnesium can reduce the bioavailability of levodopa/carbidopa.
Clinical research in healthy volunteers shows that taking magnesium oxide 1000 mg with levodopa 100 mg/carbidopa 10 mg reduces the area under the curve (AUC) of levodopa by 35% and of carbidopa by 81%. In vitro and animal research shows that magnesium produces an alkaline environment in the digestive tract, which might lead to degradation and reduced bioavailability of levodopa/carbidopa.
Aminoglycoside Antibiotics
Concomitant use of aminoglycoside antibiotics and magnesium can increase the risk for neuromuscular weakness.
Both aminoglycosides and magnesium reduce presynaptic acetylcholine release, which can lead to neuromuscular blockade and possible paralysis. This is most likely to occur with high doses of magnesium given intravenously.
Antacids
Use of acid reducers may reduce the laxative effect of magnesium oxide.
A retrospective analysis shows that, in the presence of H2 receptor antagonists (H2RAs) or proton pump inhibitors (PPIs), a higher dose of magnesium oxide is needed for a laxative effect. This may also occur with antacids. Under acidic conditions, magnesium oxide is converted to magnesium chloride and then to magnesium bicarbonate, which has an osmotic laxative effect. By reducing acidity, antacids may reduce the conversion of magnesium oxide to the active bicarbonate salt.
Bictegravir/Emtricitabine/Tenofovir Alafenamide (Biktarvy)
Magnesium might decrease levels of bictegravir/emtricitabine/tenofovir alafenamide by reducing its absorption.
Advise patients that bictegravir/emtricitabine/tenofovir alafenamide should be taken at least 2 hours before or 6 hours after magnesium containing products.
Bisphosphonates
Magnesium can decrease absorption of bisphosphonates.
Cations, including magnesium, can decrease bisphosphonate absorption. Advise patients to separate doses of magnesium and these drugs by at least 2 hours.
Calcium Channel Blockers
Magnesium can have additive effects with calcium channel blockers, although evidence is conflicting.
Magnesium inhibits calcium entry into smooth muscle cells and may therefore have additive effects with calcium channel blockers. Severe hypotension and neuromuscular blockades may occur when nifedipine is used with intravenous magnesium, although some contradictory evidence suggests that concurrent use of magnesium with nifedipine does not increase the risk of neuromuscular weakness. High doses of magnesium could theoretically have additive effects with other calcium channel blockers.
Digoxin
Magnesium salts may reduce absorption of digoxin.
Clinical evidence suggests that treatment with oral magnesium hydroxide or magnesium trisilicate reduces absorption of digoxin from the intestines. This may reduce the blood levels of digoxin and decrease its therapeutic effects.
Potassium-Sparing Diuretics
Potassium-sparing diuretics decrease excretion of magnesium, possibly increasing magnesium levels.
Potassium-sparing diuretics also have magnesium-sparing properties, which can counteract the magnesium losses associated with loop and thiazide diuretics. Theoretically, increased magnesium levels could result from concomitant use of potassium-sparing diuretics and magnesium supplements.
Quinolone Antibiotics
Magnesium decreases absorption of quinolones.
Magnesium can form insoluble complexes with quinolones and decrease their absorption. Advise patients to take these drugs at least 2 hours before, or 4 to 6 hours after, magnesium supplements.
Skeletal Muscle Relaxants
Parenteral magnesium alters the pharmacokinetics of skeletal muscle relaxants, increasing their effects and accelerating the onset of effect.
Parenteral magnesium shortens the time to onset of skeletal muscle relaxants by about 1 minute and prolongs the duration of action by about 2 minutes. Magnesium potentiates the effects of skeletal muscle relaxants by decreasing calcium-mediated release of acetylcholine from presynaptic nerve terminals, reducing postsynaptic sensitivity to acetylcholine, and having a direct effect on the membrane potential of myocytes. Magnesium also has vasodilatory actions and increases cardiac output, allowing a greater amount of muscle relaxant to reach the motor end plate. A clinical study found that low-dose rocuronium (0.45 mg/kg), when given after administration of magnesium 30 mg/kg over 10 minutes, has an accelerated onset of effect, which matches the onset of effect seen with a full-dose rocuronium regimen (0.6 mg/kg). In another clinical study, onset times for rocuronium doses of 0.3, 0.6, and 1.2 mg/kg were 86, 76, and 50 seconds, respectively, when given alone, but were reduced to 66, 44, and 38 seconds, respectively, when the doses were given after a 15-minute infusion of magnesium sulfate 60 mg/kg. Giving intraoperative intravenous magnesium sulfate, 50 mg/kg loading dose followed by 15 mg/kg/hour, reduces the onset time of rocuronium, enhances its clinical effects, reduces the dose of intraoperative opiates, and prolongs the spontaneous recovery time. It does not affect the activity of subsequently administered neostigmine.
Sulfonylureas
Magnesium increases the systemic absorption of sulfonylureas, increasing their effects and side effects.
Clinical research shows that administration of magnesium hydroxide with glyburide increases glyburide absorption, increases maximal insulin response by 35-fold, and increases the risk of hypoglycemia, when compared with glyburide alone. A similar interaction occurs between magnesium hydroxide and glipizide. The mechanism of this effect appears to be related to the elevation of gastrointestinal pH by magnesium-based antacids, increasing solubility and enhancing absorption of sulfonylureas.
Tetracycline Antibiotics
Magnesium decreases absorption of tetracyclines.
Magnesium can form insoluble complexes with tetracyclines in the gut and decrease their absorption and antibacterial activity. Advise patients to take these drugs 1 hour before or 2 hours after magnesium supplements.
Anticoagulant/Antiplatelet Drugs
Theoretically, magnesium may have antiplatelet effects, but the evidence is conflicting.
In vitro evidence shows that magnesium sulfate inhibits platelet aggregation, even at low concentrations. Some preliminary clinical evidence shows that infusion of magnesium sulfate increases bleeding time by 48% and reduces platelet activity. However, other clinical research shows that magnesium does not affect platelet aggregation, although inhibition of platelet-dependent thrombosis can occur.
Gabapentin (Neurontin)
Gabapentin absorption can be decreased by magnesium.
Clinical research shows that giving magnesium oxide orally along with gabapentin decreases the maximum plasma concentration of gabapentin by 33%, time to maximum concentration by 36%, and area under the curve by 43%. Advise patients to take gabapentin at least 2 hours before, or 4 to 6 hours after, magnesium supplements.
Sevelamer (Renagel, Renvela)
Sevelamer may increase serum magnesium levels.
In patients on hemodialysis, sevelamer use was associated with a 0.28 mg/dL increase in serum magnesium. The mechanism of this interaction remains unclear.
Strontium
Androgens
Theoretically, androgens might reduce the excretion of strontium, potentially increasing its effects and adverse effects.
A small clinical study suggests that treatment with androgens such as testosterone, nandrolone, oxandrolone, and oxymetholone for 5-6 weeks might decrease urinary strontium excretion. The clinical significance of this interaction is unknown.
Antacids
Antacids can reduce the absorption of strontium, potentially decreasing its effectiveness.
Aluminum hydroxide and magnesium hydroxide can reduce absorption of strontium ranelate by 20% to 25%. Calcium can reduce its absorption to 60% to 70%. Avoid taking antacids within 2 hours of a dose of strontium ranelate. This interaction has also been reported with orally-administered radioactive strontium-85. It will likely also occur with other forms of strontium.
Estrogens
Theoretically, estrogens might reduce the excretion of strontium, potentially increasing its effects and adverse effects.
A small clinical study suggests that treatment with estrogens for 5-6 weeks might decrease urinary strontium excretion. The clinical significance of this interaction is unknown.
Quinolone Antibiotics
Theoretically, strontium might decrease the absorption of quinolone antibiotics.
Strontium is a divalent cation with similar properties to calcium. It is likely to form complexes with quinolones in the gastrointestinal (GI) tract, preventing absorption of the antibiotic. Recommend taking strontium supplements at least 2 hours before or after quinolones to avoid an interaction.
Tetracycline Antibiotics
Theoretically, strontium might decrease the absorption of tetracycline antibiotics.
Strontium is a divalent cation with similar properties to calcium. It is likely to form complexes with tetracyclines in the gastrointestinal (GI) tract, preventing absorption of the antibiotic. Recommend taking strontium supplements at least 2 hours before or after tetracyclines to avoid an interaction.
