HelloPharmacist Scorecard of Quantum Iron Support by Quantum Nutrition Labs

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
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 1 of its 9 active ingredients.
  • “Iron Elite” is listed as a grouped ingredient — the label gives one combined amount (656 mg) without saying how much of each component you get.
  • “Blood Advantage” is listed as a grouped ingredient — the label gives one combined amount (180 mg) without saying how much of each component you get.

Quantum Iron Support contains 9 ingredients total, including iron as its primary active component for addressing low iron levels. The product also contains rice bran, bilberry, chlorella, beet, tomato, pumpkin, oat grass, and reishi mushroom extract — a blend of whole-food and plant extracts.

Two of these ingredients, Iron Elite and Blood Advantage, are proprietary blends whose component ingredients are listed individually above. The inactive ingredients are cellulose and water.

Does it work?

Strong 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
Strong

Clinical evidence supports at least one of this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: blood support with live-source iron.
  • We looked for evidence on: Anemia of chronic disease, Athletic performance, Cardiovascular disease (CVD), Coronary heart disease (CHD), Dyslipidemia, Exercise-induced muscle damage — and 4 related terms.
  • The strongest evidence on file: Iron is rated "Effective" for Anemia of chronic disease (Natural Medicines).
  • Also on file: Iron is rated "Effective" for Iron deficiency anemia.
  • Also on file: Oats is rated "Likely Effective" for Coronary heart disease (CHD), Dyslipidemia.

Iron is effective for iron deficiency anemia, anemia of chronic disease, and pregnancy-related iron deficiency according to clinical evidence. It is possibly effective for heart failure.

Rice bran is possibly effective for high cholesterol (dyslipidemia), though evidence is limited. Oat grass is likely effective for high cholesterol and heart disease prevention.

Bilberry, beet, tomato, pumpkin, and reishi mushroom lack sufficient reliable evidence to establish their effectiveness for the conditions listed in the product facts, or the evidence suggests they may not work for certain uses. The evidence on this product's overall effectiveness as a combination is not on file.

The evidence, ingredient by ingredient Iron Beet Pumpkin Oats Rice Bran Bilberry Chlorella Tomato

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 9 of the 9 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 9 of 9.
  • General safety write-ups exist for 9 of 9.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Iron is generally well tolerated at recommended doses when there is a genuine need, but excess iron can be toxic and should only be used when indicated. Common side effects include abdominal pain, constipation, diarrhea, nausea, and vomiting.

Rice bran, bilberry, and oat grass are generally well tolerated as foods; concentrated supplements have less safety data. Chlorella is generally well tolerated short term, but product quality varies widely and long-term safety is unclear.

Beet and tomato are well tolerated in food amounts. Pumpkin is generally well tolerated.

Reishi mushroom is generally well tolerated short term, but long-term safety is not well studied. Common side effects across the ingredients include gastrointestinal effects (bloating, flatulence, abdominal discomfort, nausea, diarrhea) and, rarely, allergic reactions.

Reishi may cause dizziness, dry mouth, itching, rash, and stomach upset.

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 7 of the 9 matched ingredients can interact with medications — Bilberry, Beet, Pumpkin, Oats, Reishi Mushroom, among others.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications; lithium; Parkinson's medications.
  • For scale: 1,191 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 taking Quantum Iron Support, double-check these medication types with your pharmacist, worst first: levodopa, quinolone and tetracycline antibiotics, bisphosphonates, levothyroxine, methyldopa, mycophenolate mofetil, and penicillamine (all due to iron); anticoagulant and antiplatelet drugs like warfarin (due to chlorella and bilberry); antidiabetes drugs and insulin (due to bilberry, oat grass, and reishi); blood pressure drugs (due to beet and reishi); lithium (due to pumpkin); cytochrome P450 substrates including CYP3A4 and CYP1A2 drugs (due to beet); photosensitizing drugs (due to chlorella); and erlotinib (due to bilberry).

Each ingredient & the kinds of drugs it affects

For each ingredient in Quantum Iron 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.

Reishi Fruiting Body Extract 3 drug types · 375 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, high doses of reishi mushroom might increase the risk of bleeding.
A dose of 1.5 grams daily of reishi mushroom does not seem to decrease platelet aggregation, but a higher dose of 3 grams daily does.

Likelihood Possible Evidence D
Antidiabetes Drugs

Theoretically, reishi mushroom might have additive effects with antidiabetes drugs.
Animal research suggests that reishi mushroom decreases blood sugar. However, in patients with type 2 diabetes, taking reishi mushroom does not reduce fasting glucose levels, and its effects on glycated hemoglobin are inconsistent.

Likelihood Possible Evidence D
Antihypertensive Drugs

Theoretically, concurrent use of reishi mushroom with antihypertensive drugs might increase the risk of hypotension.
Reishi mushroom has shown hypotensive activity in animal research. Clinical evidence suggests that reishi mushroom reduces blood pressure in some, but not all, patients with hypertension.

Likelihood Possible Evidence D
Reishi Fruiting Body Extract full monograph & interactions

Chlorella2 drug types · 337 drugs

Photosensitizing Drugs

Theoretically, chlorella might have additive effects with photosensitizing drugs.
Chlorella has been reported to cause photosensitization. In five case reports, patients who had ingested chlorella exhibited swelling followed by erythematopurpuric lesions on sun-exposed areas of the body. Theoretically, concomitant use with photosensitizing drugs may exacerbate effects.

Likelihood Possible Evidence D
Warfarin (Coumadin)

Theoretically, chlorella might reduce the clinical effects of warfarin.
Chlorella contains significant amounts of vitamin K. There is at least one case report of warfarin therapy becoming sub-therapeutic after initiation of chlorella supplements.

Likelihood Possible Evidence D
Chlorella full monograph & interactions

Bilberry4 drug types · 275 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, bilberry fruit extract might increase the risk of bleeding when taken with anticoagulant or antiplatelet drugs.
In vitro, animal, and clinical research suggest that anthocyanidin extracts from bilberry can inhibit platelet aggregation.

Likelihood Possible Evidence D
Antidiabetes Drugs

Theoretically, bilberry leaf or fruit extract may increase the risk of hypoglycemia when taken with antidiabetes drugs.
Animal research suggests that bilberry leaf extract might have blood glucose-lowering activity. Also, one small clinical trial in patients with type 2 diabetes shows that taking bilberry fruit extract 470 mg as a single dose prior to an oral glucose tolerance test lowers plasma glucose levels when compared with placebo.

Likelihood Possible Evidence D
Cytochrome P450 2E1 (Cyp2E1) Substrates

Theoretically, bilberry fruit extract might decrease levels of drugs metabolized by CYP2E1.
Animal research shows that exposure to small concentrations of bilberry extract in drinking water for around one month increased CYP2E1 activity by 31%. However, exposure over a 2-month period did not increase CYP2E1 activity. This effect has not been reported in humans.

Likelihood Possible Evidence D
Erlotinib (Tarceva)

Theoretically, bilberry fruit extract might reduce the efficacy of erlotinib.
In vitro research suggests that bilberry fruit extract and its constituents, delphinidin and delphinidin-3-O-glucoside, inhibit the activity of erlotinib. This interaction has not been reported in humans.

Likelihood Possible Evidence D
Bilberry full monograph & interactions

Iron13 drug types · 80 drugs

Bictegravir/Emtricitabine/Tenofovir Alafenamide (Biktarvy)

Iron might decrease levels of bictegravir/emtricitabine/tenofovir alafenamide by reducing its absorption when taken in a fasting state.
Advise patients that bictegravir/emtricitabine/tenofovir alafenamide and iron can be taken together if taken with food. However, if taken on an empty stomach, bictegravir/emtricitabine/tenofovir alafenamide should not be taken with, or 2 hours after, iron containing products.

Likelihood Probable Evidence D
Bisphosphonates

Iron reduces the absorption of bisphosphonates.
Advise patients that doses of bisphosphonates should be separated by at least two hours from doses of all other medications, including supplements such as iron. Divalent cations, including iron, can decrease absorption of bisphosphonates by forming insoluble complexes in the gastrointestinal tract.

Likelihood Probable Evidence D
Denosumab (Prolia, Others)

Administration of intravenous iron within one month of denosumab administration might increase the risk of severe hypophosphatemia and hypocalcemia.
A case of severe hypocalcemia (albumin corrected calcium 6.88 mg/dL, ionized calcium 3.68 mg/dL) and hypophosphatemia (<0.5 mg/dL) with respiratory acidosis, QT interval prolongation, and nonsustained ventricular tachycardia was reported in a 76-year-old male who had received an iron polymaltose infusion within 2 weeks of a subcutaneous injection of denosumab. Serum parathyroid hormone was also elevated (348 pg/mL). Subsequent iron infusions with iron polymaltose and ferric carboxymaltose were followed by transient hypophosphatemia, but without hypocalcemia. Additionally, a literature review describes 6 additional cases of hypophosphatemia and hypocalcemia in patients 52-92 years of age who had been administered intravenous iron as either ferric carboxymaltose or iron polymaltose and subcutaneous denosumab within 1-4 weeks of each other.

Likelihood Possible Evidence D
Dolutegravir (Tivicay)

Iron might decrease dolutegravir levels by reducing its absorption.
Advise patients to take dolutegravir at least 2 hours before or 6 hours after taking iron. Pharmacokinetic research shows that iron can decrease the absorption of dolutegravir from the gastrointestinal tract through chelation. When taken under fasting conditions, a single dose of ferrous fumarate 324 mg orally along with dolutegravir 50 mg reduces overall exposure to dolutegravir by 54%.

Likelihood Probable Evidence B
Integrase Inhibitors

Theoretically, taking iron along with integrase inhibitors might decrease the levels and clinical effects of these drugs.
Iron is a divalent cation. There is concern that iron may decrease the absorption of integrase inhibitors from the gastrointestinal tract through chelation. One pharmacokinetic study shows that iron can decrease blood levels of the specific integrase inhibitor dolutegravir through chelation. Also, other pharmacokinetic research shows that other divalent cations such as calcium can decrease the absorption and levels of some integrase inhibitors through chelation.

Likelihood Possible Evidence D
Levodopa

Iron might decrease levodopa levels by reducing its absorption.
Advise patients to separate doses of levodopa and iron as much as possible. There is some evidence in healthy people that iron forms chelates with levodopa, reducing the amount of levodopa absorbed by around 50%. The clinical significance of this hasn't been determined.

Likelihood Probable Evidence B
Levothyroxine (Synthroid, Others)

Iron might decrease levothyroxine levels by reducing its absorption.
Advise patients to separate levothyroxine and iron doses by at least 2 hours. Iron can decrease the absorption and efficacy of levothyroxine by forming insoluble complexes in the gastrointestinal tract.

Likelihood Probable Evidence B
Methyldopa (Aldomet)

Iron might decrease methyldopa levels by reducing its absorption.
Advise patients to separate methyldopa and iron doses by at least 2 hours. Iron can decrease the absorption of methyldopa from the gastrointestinal tract through chelation, resulting in increases in blood pressure.

Likelihood Probable Evidence B
Mycophenolate Mofetil (Cellcept)

Theoretically, iron might decrease mycophenolate mofetil levels by reducing its absorption.
Advise patients to take iron 4-6 hours before, or 2 hours after, mycophenolate mofetil. It has been suggested that a decrease of absorption is possible, probably by forming nonabsorbable chelates. However, mycophenolate pharmacokinetics are not affected by iron supplementation in available clinical research.

Likelihood Unlikely Evidence D
Penicillamine (Cuprimine, Depen)

Iron might decrease penicillamine levels by reducing its absorption.
Advise patients to separate penicillamine and iron doses by at least 2 hours. Oral iron supplements can reduce absorption of penicillamine by 30% to 70%, probably due to chelate formation. In people with Wilson's disease, this interaction has led to reduced efficacy of penicillamine.

Likelihood Probable Evidence D
Quinolone Antibiotics

Iron might decrease levels of quinolone antibiotics by reducing their absorption.
Advise patients to separate quinolone antibiotics and iron doses by at least 2 hours. Iron decreases the absorption of quinolones due to formation of insoluble complexes in the gastrointestinal tract.

Likelihood Probable Evidence D
Tetracycline Antibiotics

Iron might decrease levels of tetracycline antibiotics by reducing their absorption.
Advise patients to take iron at least 2 hours before or 4 hours after tetracycline antibiotics. Concomitant use can decrease absorption of tetracycline antibiotics from the gastrointestinal tract by 50% to 90%.

Likelihood Probable Evidence D
Chloramphenicol

Theoretically, taking chloramphenicol with iron might reduce the response to iron therapy in iron deficiency anemia.
Chloramphenicol interferes with erythrocyte maturation. However, since chloramphenicol isn't usually taken for prolonged periods, this isn't likely to be clinically significant.

Quantum Iron Support by Quantum Nutrition Labs: Common Questions

Does Quantum Iron Support by Quantum Nutrition Labs interact with any medications?
Yes. Based on its ingredients, Quantum Iron Support has a known interaction with 1,190 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Quantum Iron Support contains 7 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 iron safe to take during pregnancy?
Iron is rated likely safe in pregnancy and is commonly recommended to prevent pregnancy-related iron deficiency. However, the dose should be guided by your prenatal care provider, not self-directed. Talk with your doctor about what's right for you.
What are the most common side effects of iron supplements?
The most common side effects are abdominal pain, constipation, diarrhea, nausea, and vomiting. Gastrointestinal upset is the main reason people stop taking iron. Taking iron with or without food may affect side effects, so ask your pharmacist about timing.
Can I take this product if I'm on thyroid medication?
Iron can reduce how much thyroid medication (levothyroxine) your body absorbs, making it less effective. You'll need to separate doses by at least 2 hours. Check with your pharmacist about the best timing for your specific schedule.
What does oat grass do in this product?
Oat grass is likely effective for lowering cholesterol and supporting heart health. It's also a source of fiber. However, if you take insulin or diabetes drugs, oat grass may lower your blood sugar too much, so mention it to your doctor.
Does this product have any ingredients I couldn't check for interactions?
We could not check iron supplement interactions for two blend names (Iron Elite and Blood Advantage) — their full ingredient lists are shown above, so refer to those. All other individual ingredients have been checked against our interaction database.
Is reishi mushroom safe to take long-term?
Reishi is generally well tolerated short term, but long-term safety has not been well studied. There isn't enough data on file to say whether it's safe in pregnancy or while breastfeeding, so talk with your doctor if either applies to you.
