What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 6 of its 6 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

Candida Support contains six active ingredients. Biotin is a B vitamin that supports normal hair, skin, and nail growth and is well tolerated even at higher doses.

Magnesium is an essential mineral involved in muscle and nerve function, bone health, and energy production. Caprylic acid is a medium-chain fatty acid that occurs naturally in coconut and palm oils.

Black walnut is a tree nut traditionally used in herbal practice. Oregano oil powder is a concentrated form of the culinary herb oregano.

Pau d'arco is a South American tree bark also called lapacho or tabebuia. The capsule also contains inactive ingredients—hypromellose, microcrystalline cellulose, calcium citrate, stearic acid, and silicon dioxide—which are fillers and binders.

Does it work?

Insufficient evidence
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Insufficient

There isn't enough reliable clinical evidence to rate this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: support healthy intestinal flora balance.
  • We looked for evidence on: Intestinal parasite infection, Candida overgrowth, Dysbiosis, Yeast balance.
  • The closest evidence on file: Oregano is rated "Insufficient Reliable Evidence To Rate" for Intestinal parasite infection (Natural Medicines).

Biotin is likely effective for biotin deficiency; however, the evidence is insufficient to rate it for multiple sclerosis or alopecia areata (hair loss), and it appears possibly ineffective for seborrheic dermatitis (a flaky skin condition). Magnesium is effective for dyspepsia (indigestion), constipation, and certain pregnancy-related conditions, and is effective for correcting low magnesium levels.

For the other four ingredients—caprylic acid, black walnut, oregano oil powder, and pau d'arco—the evidence is insufficient to establish effectiveness in our data. This product's primary purpose of supporting candida (yeast) management is not covered by the effectiveness ratings we hold.

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 6 of the 6 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 6 of 6.
  • General safety write-ups exist for 6 of 6.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Biotin is generally well tolerated, even at fairly high doses; the data show it's likely safe in pregnancy and lactation. However, rare cases of mild diarrhea have been reported at very high doses, and one isolated case of an inflammatory reaction was noted.

Magnesium is generally well tolerated at recommended amounts and is likely safe or possibly safe in pregnancy and lactation under medical guidance. The most common side effects are gastrointestinal—diarrhea, nausea, vomiting—and rarely serious effects have been reported at extremely high doses.

Caprylic acid appears well tolerated short-term and may cause mild abdominal discomfort or taste changes; pregnancy and breastfeeding safety data are limited. Black walnut is possibly unsafe in pregnancy and breastfeeding, and the leaf, bark, and hull can cause gastrointestinal upset due to tannin content; it can also trigger allergic reactions in people with tree nut allergies.

Oregano oil is possibly unsafe in pregnancy; the data show gastrointestinal upset and, rarely, severe allergic reactions including anaphylaxis. Pau d'arco is possibly unsafe in pregnancy and breastfeeding, and at doses above 1.5 grams daily the lapachol compound may cause anemia, bleeding risk, severe nausea, vomiting, and diarrhea.

At least one ingredient has a documented Major-severity interaction. Check your medications for a personalized result.

Why this rating?
  • 4 of the 6 matched ingredients can interact with medications — Oregano, Pau D'arco, Magnesium, Caprylic Acid.
  • The most serious interaction on file is rated Major.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications; heart-rhythm medications; Parkinson's medications.
  • For scale: 542 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Before starting Candida Support, double-check if you take levodopa/carbidopa for Parkinson's disease (major interaction). Also flag any blood thinners or antiplatelet drugs you're on (moderate risk with caprylic acid, oregano oil, and pau d'arco), blood pressure medications, diabetes medications, skeletal muscle relaxants, water pills, stomach acid reducers, NSAIDs like ibuprofen, quinolone antibiotics, or bisphosphonate bone drugs.

No interactions are documented for biotin or black walnut in our data.

The bottom line

Scorecard at a glanceFully disclosed formula with insufficient evidence for its stated purpose. Major medication interactions have been identified, and safety information is well characterized.

If you don't take Parkinson's medications, blood thinners, diabetes drugs, blood pressure medications, or certain antibiotics, this product may be worth discussing with your pharmacist. Those with tree nut allergies should avoid it because of the black walnut.

Pregnant or breastfeeding women should talk to their doctor first—several ingredients carry safety concerns during these periods. Always check your full medication list against the interaction tool on this page.

Each ingredient & the kinds of drugs it affects

For each ingredient in Candida Support 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.

Magnesium15 drug types · 295 drugs

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.

Likelihood Probable Evidence B
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.

Likelihood Possible Evidence D
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.

Likelihood Possible Evidence D
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.

Likelihood Probable Evidence D
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.

Likelihood Probable Evidence B
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.

Likelihood Possible Evidence D
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.

Likelihood Possible Evidence B
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.

Likelihood Probable Evidence D
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.

Likelihood Probable Evidence D
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.

Likelihood Probable Evidence A
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.

Likelihood Probable Evidence B
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.

Likelihood Probable Evidence D
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.

Likelihood Unlikely Evidence B
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.

Likelihood Unlikely Evidence B
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.

Likelihood Possible Evidence B
Magnesium full monograph & interactions

Caprylic Acid3 drug types · 262 drugs

Antihypertensive Drugs

Theoretically, caprylic acid might increase the risk of hypotension when used with antihypertensive drugs.
Animal research suggests that caprylic acid might have positive inotropic effects, resulting in reduced arterial pressure and vascular resistance and increased cardiac output.

Likelihood Possible Evidence D
Nonsteroidal Anti-Inflammatory Drugs (Nsaids)

Theoretically, caprylic acid might increase plasma concentrations of NSAIDs.
In vitro research suggests that caprylic acid might displace NSAIDs from binding sites on albumin. This effect has not been reported in humans.

Likelihood Possible Evidence D
Warfarin (Coumadin)

Theoretically, caprylic acid might increase plasma concentrations of warfarin.
In vitro research suggests that high doses of caprylic acid might displace warfarin from albumin binding sites. This effect has not been reported in humans.

Likelihood Possible Evidence D
Caprylic Acid full monograph & interactions

Oregano oil powder2 drug types · 208 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, oregano might increase the risk of bleeding when taken with anticoagulant or antiplatelet drugs.
In vitro research shows that aristolochic acid isolated from oregano leaves has antithrombin activity. It has also been reported that oregano oil inhibits arachidonic acid-induced, and ADP-induced, platelet aggregation.

Likelihood Possible Evidence D
Antidiabetes Drugs

Theoretically, oregano might increase the risk for hypoglycemia when taken with antidiabetes drugs.
In vitro and animal research shows that oregano extracts might lower blood glucose levels.

Likelihood Possible Evidence D
Oregano oil powder full monograph & interactions

Pau d'Arco1 drug type · 122 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, pau d'arco might increase the risk of bleeding when taken with anticoagulant or antiplatelet drugs.
In vitro research shows that pau d'arco reduces platelet aggregation and may interfere with vitamin K. One clinical study shows that taking the lapachol constituent of pau d'arco in doses above 1.5 grams daily increases the risk of bleeding. The effects of whole pau d'arco or pau d'arco extract in humans are unclear.

Candida Support by LuckyVitamin: Common Questions

Does Candida Support by LuckyVitamin interact with any medications?
Yes. Based on its ingredients, Candida Support has a known interaction with 542 medications, including 6 rated major. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Candida Support contains 6 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Is this safe if I'm pregnant or breastfeeding?
The safety picture is mixed. Biotin and magnesium are likely safe or possibly safe during pregnancy under your doctor's guidance, but black walnut, oregano oil, and pau d'arco are possibly unsafe during pregnancy—so avoid them. Similarly, oregano oil and pau d'arco lack sufficient safety data for breastfeeding, and caprylic acid safety while breastfeeding is unknown. Talk to your doctor before using this product in either situation.
Can I take this if I have a tree nut allergy?
No. Black walnut is a tree nut and can trigger allergic reactions in sensitive people. Because tree nuts are a major food allergen, this product is not safe for you.
What's biotin in here for?
Biotin is a B vitamin that supports normal hair, skin, and nail growth. It's the only ingredient in this product that has proven effectiveness—specifically for biotin deficiency—though it doesn't appear to help with seborrheic dermatitis or hair loss from alopecia areata.
Does this actually work for candida?
The evidence data we hold doesn't cover candida support. The ingredient effectiveness ratings in our records are for other uses—like biotin for nail health and magnesium for constipation—so I can't tell you from our data whether this product works for your specific goal.
What are the most common side effects?
Magnesium commonly causes gastrointestinal upset—diarrhea, nausea, or vomiting. Caprylic acid may cause mild abdominal discomfort or a change in taste. Biotin rarely causes mild diarrhea at very high doses. Oregano oil and pau d'arco can also cause gastrointestinal upset, and pau d'arco at high doses carries a risk of bleeding and anemia.
Can I take this with my other supplements?
It depends on what they are. Magnesium in particular can reduce the absorption of several drugs and supplements. Use the interaction checker on this page to run your full list—including other supplements and any medications—to be sure.
