HelloPharmacist Scorecard of Asc2P by SuperSmart
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
Low disclosure
Asc2P contains 2 active ingredients: vitamin C, which supports immune function and acts as an antioxidant, and magnesium, a mineral involved in muscle and nerve function, energy production, and bone health. The product also contains acacia gum as an inactive ingredient.
Does it work?
Couldn't assess
Vitamin C is effective for preventing vitamin C deficiency and is possibly effective for anemia of chronic disease, atrial fibrillation, cataracts, and exercise-induced respiratory infections. Magnesium is effective for dyspepsia (indigestion), constipation, and low magnesium levels, and is possibly effective for preventing pre-eclampsia in pregnancy.
How safe is it?
Well-documented data
Vitamin C is generally well tolerated at normal dietary and supplement doses, but very high doses can cause abdominal cramps, heartburn, diarrhea, nausea, and vomiting — particularly above 2 grams daily. Rare cases of kidney stones (in susceptible people) and, with very high intravenous doses, kidney damage have been reported.
Magnesium is generally well tolerated; the most common side effects are diarrhea, nausea, and vomiting, more likely at higher doses. For pregnancy, normal amounts of vitamin C from food and prenatal vitamins are fine, but avoid high-dose supplements unless your doctor advises it.
Magnesium is needed in pregnancy but use supplements only under your doctor's guidance. For breastfeeding, normal dietary amounts of both are appropriate; check with your doctor before using supplements.
Meds to double-check
Major interaction found
Before taking this product, double-check with your doctor or pharmacist if you take Parkinson's medication (levodopa/carbidopa), blood thinners like warfarin, chemotherapy drugs, thyroid medication (levothyroxine), HIV drugs (indinavir), skeletal muscle relaxants, diabetes medications (sulfonylureas), quinolone antibiotics, bisphosphonates, calcium channel blockers, or potassium-sparing diuretics. The interaction with levodopa/carbidopa is the most serious.
The bottom line
Scorecard at a glanceFormula with limited ingredient disclosure with no assessable stated purpose. Major medication interactions have been identified, and safety information is well characterized.
Asc2P may help with vitamin C deficiency, general wellness, and digestive support, but it carries documented interactions with common medications including blood thinners, chemotherapy drugs, thyroid medication, and Parkinson's treatment. If you take any prescription medication — especially those for heart, nerve, or blood-sugar control — talk it over with your doctor or pharmacist before starting this product.
They can review your specific drugs and confirm it's safe for you.

Asc2P by SuperSmart Drug Interactions
HelloPharmacist Interaction Report
Asc2P by SuperSmart contains two active ingredients — vitamin C and magnesium — that together interact with a substantial range of medications.
The most serious interaction is magnesium with levodopa/carbidopa (Sinemet), a Parkinson's drug: magnesium can cut levodopa levels by about 35%, significantly reducing the medication's effectiveness.
Read the full breakdown — every affected drug type, severity by severity
Vitamin C interacts with estrogens (found in birth control pills and hormone replacement therapy), where it may raise estrogen blood levels by up to 55%. It also concerns chemotherapy drugs — both alkylating agents and antitumor antibiotics — because its antioxidant effect might weaken them.
Vitamin C can also reduce warfarin (a blood thinner) effectiveness at higher doses, increase levothyroxine (thyroid medication) absorption, and modestly lower indinavir (an HIV drug) levels.
Magnesium has additional moderate interactions with skeletal muscle relaxants (which it may strengthen), potassium-sparing diuretics, calcium channel blockers, sulfonylureas (diabetes drugs — it may increase their effect and hypoglycemia risk), quinolone antibiotics, bisphosphonates, and acid-reducing medications. Altogether, these interactions span 443 individual medications.
Check your exact medications with the search tool on this page before starting this product, and run the list past your doctor or pharmacist if you take any blood thinners, chemotherapy agents, thyroid medication, or drugs for Parkinson's disease, diabetes, or heart rhythm.

Read the full Magnesium Ascorbyl Phosphate + Amiloride interactionEach ingredient & the kinds of drugs it affects
For each ingredient in Asc2P 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 Ascorbyl Phosphate
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.
