HelloPharmacist Scorecard of Pantomax Supreme by Maxi Health
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
Pantomax Supreme contains 2 active ingredients: pantothenic acid (vitamin B5) and PureWay-C, a form of vitamin C. Pantothenic acid is a B vitamin that supports energy metabolism and is used to prevent and treat deficiency.
Vitamin C is an antioxidant vitamin involved in immune function, collagen formation, and wound healing. The product also contains inactive ingredients — cellulose, Enzymax, and magnesium stearate — which serve as fillers and binders to hold the capsule together.
Does it work?
Strong evidence
Pantothenic acid is effective for treating pantothenic acid deficiency. The evidence is insufficient to rate it for hay fever, alcoholism, or alopecia areata, and it appears ineffective for radiation dermatitis.
Vitamin C is effective for vitamin C deficiency and possibly effective for anemia of chronic disease, atrial fibrillation, cataracts, and exercise-induced respiratory infections. For other uses, the evidence we hold does not establish effectiveness.
How safe is it?
Well-documented data
Pantothenic acid is generally well tolerated at typical supplement doses; diarrhea has been reported orally. Normal dietary amounts and prenatal-vitamin doses are considered safe, but consult your doctor before taking high-dose supplements.
Vitamin C is generally safe at normal dietary and supplement doses, but very high doses can cause abdominal cramps, heartburn, diarrhea, nausea, and — in those prone to kidney stones — stone formation. Serious rare cases of kidney damage have been reported after high-dose intravenous infusions.
Avoid high-dose supplements unless your doctor directs otherwise. Pantothenic acid is likely safe in pregnancy and lactation.
Vitamin C is likely safe in pregnancy and lactation, though one rating suggests possibly unsafe — talk with your doctor or pharmacist about your individual situation.
Meds to double-check
Moderate interaction found
If you take a blood thinner like warfarin, birth control pills or hormone replacement therapy, chemotherapy drugs, levothyroxine or other thyroid medication, aluminum compounds, the antipsychotic fluphenazine, or the HIV medication indinavir, double-check with your pharmacist or doctor before using this product — vitamin C in the formula may affect how these medications work.
The bottom line
Scorecard at a glanceFully disclosed formula with strong clinical evidence behind its ingredients' uses. Moderate medication interactions have been identified, and safety information is well characterized.
Pantomax Supreme may be useful if you have a pantothenic acid or vitamin C deficiency or want general antioxidant support, but the vitamin C component has documented interactions with blood thinners, birth control, chemotherapy, thyroid medications, and several other drug types. If you take any prescription medications, especially anticoagulants or hormonal contraceptives, check with your doctor or pharmacist before starting.
High-dose vitamin C can also cause gastrointestinal side effects and, in susceptible people, kidney stones.

Pantomax Supreme by Maxi Health Drug Interactions
HelloPharmacist Interaction Report
Pantomax Supreme by Maxi Health contains pantothenic acid and PureWay-C (vitamin C).
Pantothenic acid has no documented interactions with medications. Vitamin C, however, interacts with a number of drug types — the most serious being a moderate-severity interaction with blood thinners like warfarin (Coumadin), where high-dose vitamin C may reduce the drug's effectiveness and increase your clotting risk.
Read the full breakdown — every affected drug type, severity by severity
Vitamin C also moderately interacts with birth control pills and hormone replacement therapy by raising estrogen levels in your blood — potentially by up to 55% in some cases. It can similarly reduce the effectiveness of certain chemotherapy drugs (alkylating agents and antitumor antibiotics) by counteracting their ability to generate cell-damaging free radicals.
Additionally, vitamin C moderately affects thyroid medication absorption, aluminum absorption from compounds, and levels of the antipsychotic fluphenazine and the HIV drug indinavir.
Altogether, these interactions span 207 individual medications. If you take any prescription drug — especially a blood thinner, birth control, chemotherapy agent, or thyroid medication — check your exact medications with the tool below before starting this product.

For each ingredient in Pantomax Supreme 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.
PureWay-C
Alkylating Agents
Theoretically, antioxidant effects of vitamin C might reduce the effectiveness of alkylating agents.
The use of antioxidants like vitamin C during chemotherapy is controversial. There is concern that antioxidants could reduce the activity of chemotherapy drugs that generate free radicals, such as cyclophosphamide, chlorambucil, carmustine, busulfan, and thiotepa. In contrast, some researchers theorize that antioxidants might make chemotherapy more effective by reducing oxidative stress that could interfere with apoptosis (cell death) of cancer cells. More evidence is needed to determine what effect, if any, antioxidants such as vitamin C have on chemotherapy.
Aluminum
Vitamin C can increase the amount of aluminum absorbed from aluminum compounds.
Research in animals and humans shows that vitamin C increases aluminum absorption, theoretically by chelating aluminum and keeping it in solution where it is available for absorption. In people with normal renal function, urinary excretion of aluminum will likely increase, making aluminum retention and toxicity unlikely. Patients with renal failure who take aluminum-containing compounds such as phosphate binders should avoid vitamin C supplements in doses above the recommended dietary allowances.
Antitumor Antibiotics
Theoretically, the antioxidant effects of vitamin C might reduce the effectiveness of antitumor antibiotics.
The use of antioxidants like vitamin C during chemotherapy is controversial. There is concern that antioxidants could reduce the activity of chemotherapy drugs which generate free radicals, such as doxorubicin. In contrast, some researchers theorize that antioxidants might make chemotherapy more effective by reducing oxidative stress that could interfere with apoptosis (cell death) of cancer cells. More evidence is needed to determine what effects, if any, antioxidants such as vitamin C have on chemotherapy.
Estrogens
Vitamin C might increase blood levels of estrogens.
Increases in plasma estrogen levels of up to 55% occur under some circumstances when vitamin C is taken concurrently with oral contraceptives or hormone replacement therapy, including topical products. It is suggested that vitamin C prevents oxidation of estrogen in the tissues, regenerates oxidized estrogen, and reduces sulfate conjugation of estrogen in the gut wall. When tissue levels of vitamin C are high, these processes are already maximized and supplemental vitamin C does not have any effect on estrogen levels. Increases in plasma estrogen levels may occur when patients who are deficient in vitamin C take supplements. Monitor these patients for estrogen-related side effects.
Fluphenazine (Prolixin)
Theoretically, vitamin C might decrease levels of fluphenazine.
In one patient there was a clinically significant decrease in fluphenazine levels when vitamin C (500 mg twice daily) was started. The mechanism is not known, and there is no further data to confirm this interaction.
Indinavir (Crixivan)
Vitamin C can modestly reduce indinavir levels.
One pharmacokinetic study shows that taking vitamin C 1 gram orally once daily along with indinavir 800 mg orally three times daily reduces the area under the concentration-time curve of indinavir by 14%. The mechanism of this interaction is unknown, but it is unlikely to be clinically significant in most patients. The effect of higher doses of vitamin C on indinavir levels is unknown.
Levothyroxine (Synthroid, Others)
Vitamin C can increase levothyroxine absorption.
Two clinical studies in adults with poorly controlled hypothyroidism show that swallowing levothyroxine with a glass of water containing vitamin C 500-1000 mg in solution reduces thyroid stimulating hormone (TSH) levels and increases thyroxine (T4) levels when compared with taking levothyroxine alone. This suggests that vitamin C increases the oral absorption of levothyroxine, possibly due to a reduction in pH.
Warfarin (Coumadin)
High-dose vitamin C might reduce the levels and effectiveness of warfarin.
Vitamin C in high doses may cause diarrhea and possibly reduce warfarin absorption. There are reports of two people who took up to 16 grams daily of vitamin C and had a reduction in prothrombin time. Lower doses of 5-10 grams daily can also reduce warfarin absorption. In many cases, this does not seem to be clinically significant. However, a case of warfarin resistance has been reported for a patient who took vitamin C 500 mg twice daily. Cessation of vitamin C supplementation resulted in a rapid increase in international normalized ratio (INR). Tell patients taking warfarin to avoid taking vitamin C in excessively high doses (greater than 10 grams daily). Lower doses may be safe, but the anticoagulation activity of warfarin should be monitored. Patients who are stabilized on warfarin while taking vitamin C should avoid adjusting vitamin C dosage to prevent the possibility of warfarin resistance.
Acetaminophen (Tylenol, Others)
High-dose vitamin C might slightly prolong the clearance of acetaminophen.
A small pharmacokinetic study in healthy volunteers shows that taking high-dose vitamin C (3 grams) 1.5 hours after taking acetaminophen 1 gram slightly increases the apparent half-life of acetaminophen from around 2.3 hours to 3.1 hours. Ascorbic acid competitively inhibits sulfate conjugation of acetaminophen. However, to compensate, elimination of acetaminophen glucuronide and unconjugated acetaminophen increases. This effect is not likely to be clinically significant.
Aspirin
Acidification of the urine by vitamin C might increase aspirin levels.
It has been suggested that acidification of the urine by vitamin C could increase reabsorption of salicylates by the renal tubules, and increase plasma salicylate levels. However, short-term use of up to 6 grams daily of vitamin C does not seem to affect urinary pH or salicylate excretion, suggesting this interaction is not clinically significant.
Choline Magnesium Trisalicylate (Trilisate)
Acidification of the urine by vitamin C might increase choline magnesium trisalicylate levels.
It has been suggested that acidification of the urine by vitamin C could increase reabsorption of salicylates by the renal tubules, and increase plasma salicylate levels. However, short-term use of up to 6 grams daily of vitamin C does not seem to affect urinary pH or salicylate excretion, suggesting this interaction probably is not clinically significant.
Niacin
Vitamin C might decrease the beneficial effects of niacin on high-density lipoprotein (HDL) cholesterol levels.
A combination of niacin and simvastatin (Zocor) effectively raises HDL cholesterol levels in patients with coronary disease and low HDL levels. Clinical research shows that taking a combination of antioxidants (vitamin C, vitamin E, beta-carotene, and selenium) along with niacin and simvastatin (Zocor) attenuates this rise in HDL, specifically the HDL-2 and apolipoprotein A1 fractions, by more than 50% in patients with coronary disease. It is not known whether this adverse effect is due to a single antioxidant such as vitamin C, or to the combination. It also is not known whether it will occur in other patient populations.
Salsalate (Disalcid)
Acidification of the urine by vitamin C might increase salsalate levels.
It has been suggested that acidification of the urine by vitamin C could increase reabsorption of salicylates by the renal tubules, and increase plasma salicylate levels. However, short-term use of up to 6 grams/day vitamin C does not seem to affect urinary pH or salicylate excretion, suggesting this interaction probably is not clinically significant.
