HelloPharmacist Scorecard of Magnesium Gluconate by BulkSupplements.com
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 product contains one active ingredient: magnesium, delivered here as magnesium gluconate, a form your body absorbs readily. There are no inactive ingredients listed.
Magnesium is a mineral your body needs for muscle and nerve function, energy production, and bone health.
Does it work?
Strong evidence
Magnesium is effective for indigestion (dyspepsia), constipation, and low blood magnesium (hypomagnesemia). It's also effective for preventing and treating pre-eclampsia, a serious pregnancy complication — though this use requires medical supervision.
For other conditions, we don't have effectiveness data on file.
How safe is it?
Well-documented data
Magnesium is generally well tolerated at recommended doses. The most common side effects when taken by mouth are diarrhea, stomach irritation, nausea, and vomiting — which is why some people take it as a mild laxative.
In rare cases, very high doses have been reported to form an indigestible mass (a bezoar) in the stomach, though this is uncommon. During pregnancy, magnesium is necessary for your body, but only use supplements under your doctor's guidance — the safety data rates it as likely safe or possibly safe depending on dose and context.
While breastfeeding, normal dietary amounts are fine, but talk with your doctor before adding a supplement. Very high doses, particularly intravenously over weeks, have been associated with lower bone density in rare cases.
Meds to double-check
Major interaction found
Before starting, double-check with your doctor or pharmacist if you take levodopa/carbidopa (Parkinson's medication) — magnesium can significantly reduce how much of the drug reaches your bloodstream. Also check if you're on skeletal muscle relaxants, potassium-sparing diuretics, calcium channel blockers, quinolone antibiotics, bisphosphonate bone medications, sulfonylureas (diabetes drugs), or acid-reducing medications — the data shows magnesium can affect how these work.
The bottom line
Scorecard at a glanceFully disclosed formula with strong clinical evidence behind its ingredients' uses. Major medication interactions have been identified, and safety information is well characterized.
Magnesium Gluconate is a straightforward way to support your magnesium levels if you're deficient, and it's backed by evidence for indigestion and constipation. If you take levodopa/carbidopa for Parkinson's, a skeletal muscle relaxant, a diuretic, a heart or blood pressure medication, or certain antibiotics, you'll want to review this with your own doctor or pharmacist before starting — spacing and timing matter.
Talk it over with your healthcare provider to make sure it fits your situation.

Magnesium monograph & interactionsMagnesium Gluconate by BulkSupplements.com Drug Interactions
HelloPharmacist Interaction Report
Magnesium Gluconate by BulkSupplements.com does interact with medications, primarily through its magnesium content.
The most serious is a Major interaction with levodopa/carbidopa (Sinemet), a Parkinson's medication — magnesium can cut the drug's blood levels by up to 35%, reducing its effectiveness. This is the one interaction you'll want to be most careful about.
Read the full breakdown — every affected drug type, severity by severity
Magnesium also has Moderate interactions with several drug types. Skeletal muscle relaxants (like cyclobenzaprine) may start working faster and last longer.
Potassium-sparing diuretics (water pills that preserve potassium) may cause magnesium to accumulate in your body. Calcium channel blockers (heart and blood pressure medications) could have additive effects, possibly lowering your blood pressure more than intended.
Quinolone antibiotics (like ciprofloxacin) may not absorb well — if you take one, space your magnesium at least 2 hours before or 4 to 6 hours after. Bisphosphonates (bone medications) also need spacing: take them at least 2 hours apart from this supplement.
Antacids or acid-reducing medications (H2 blockers and proton pump inhibitors) may reduce magnesium's laxative effect. Sulfonylureas (older diabetes drugs like glyburide) may work too well, raising your risk of low blood sugar.
Altogether, these interactions span 295 individual medications. Check your exact prescriptions with the search tool on this page before you start.

For each ingredient in Magnesium Gluconate with known interactions, here are the types of medications it 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.
