HelloPharmacist Scorecard of Vegan Complete Iron 25 mg by PlantFusion
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 3 active ingredients. Folic acid is a B vitamin that supports cell division and is especially important in preventing birth defects; the body also needs it to manage folate deficiency.
Vitamin B12 is another B vitamin essential for nerve function, energy production, and red blood cell formation. Iron (in the form Ferrochel) carries oxygen in your blood and is used to treat or prevent iron deficiency anemia.
The capsule also contains inactive ingredients: cellulose, water, magnesium stearate, and silica.
Does it work?
Strong evidence
Folic acid in this product is Effective for folate deficiency and Likely Effective for preventing neural tube birth defects and managing methotrexate toxicity. It is Possibly Effective for depression, phenytoin-induced gum overgrowth, and cognitive problems.
Vitamin B12 is Effective for B12 deficiency and Imerslund-Grasbeck disease, and Likely Effective for cyanide poisoning; it is Possibly Effective for canker sores and postherpetic neuralgia (pain after shingles). Iron is Effective for iron deficiency anemia and anemia of chronic disease, and Possibly Effective for heart failure.
The specific evidence for this combination in a single supplement isn't established in our data—effectiveness depends on whether you have a documented deficiency in one or more of these nutrients.
How safe is it?
Well-documented data
Folic acid is generally well tolerated at recommended doses. At higher doses (15 mg daily), some people experience bitter taste, nausea, confusion, sleep disturbances, and irritability.
Folic acid is recommended during pregnancy at standard prenatal doses to help prevent birth defects, and it is considered safe while breastfeeding at normal amounts. Vitamin B12 is very safe with no established upper limit because excess is excreted in urine; it is needed and considered safe in both pregnancy and breastfeeding at recommended amounts.
Iron is generally well tolerated when used appropriately, but excess iron can be toxic and should only be taken when there is a real need. Common side effects are abdominal pain, constipation, diarrhea, nausea, and vomiting.
Iron is often recommended in pregnancy but dosage should be guided by your prenatal care provider. While breastfeeding, iron is generally acceptable at appropriate doses, but check with your provider.
The safety notes do not address use of folic acid in late pregnancy specifically—speak with your OB if you're pregnant.
Meds to double-check
Moderate interaction found
Check your medications before taking this product if you use seizure drugs (phenobarbital, phenytoin, primidone), cancer treatments (methotrexate, capecitabine, 5-fluorouracil), thyroid medication (levothyroxine), any antibiotics (tetracycline or quinolone types), bisphosphonates for bone health, blood pressure medication (methyldopa), Parkinson's medication (levodopa), immunosuppressants (mycophenolate), or penicillamine. The diabetes medication metformin may lower your B12 levels over time.
Use the medication checker on this page to verify each prescription and supplement you're taking.
The bottom line
Scorecard at a glanceFully disclosed formula with clinical evidence supporting its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.
This supplement is appropriate if you have documented deficiencies in folic acid, B12, or iron, or if your doctor recommends it for pregnancy support or anemia. If you take any seizure medication, thyroid drugs, antibiotics, cancer treatments, or bisphosphonates, you need to check your exact medications with the tool on this page before starting—several of these require careful timing.
Talk to your pharmacist or doctor about whether this product is right for you and whether any dose separation from your other drugs is needed.

Vegan Complete Iron 25 mg by PlantFusion Drug Interactions
HelloPharmacist Interaction Report
Vegan Complete Iron 25 mg by PlantFusion contains three active ingredients—folic acid, vitamin B12, and iron—and does interact with a number of medications.
The most serious concern is folic acid's interaction with seizure medications. Folic acid can reverse the effects of phenobarbital, phenytoin, and primidone, potentially worsening seizure control or increasing seizure frequency.
This is a Moderate severity interaction that requires close monitoring if you take any of these drugs.
Read the full breakdown — every affected drug type, severity by severity
Folic acid also interacts Moderately with cancer medications (methotrexate, capecitabine, and 5-fluorouracil), where it may reduce the drug's effectiveness or increase its toxicity. It can also antagonize pyrimethamine, used to treat certain parasitic infections.
Iron in this product has Moderate interactions with several medication types: it reduces absorption of levothyroxine (thyroid medication), tetracycline and quinolone antibiotics, bisphosphonates (osteoporosis drugs), methyldopa (blood pressure medication), levodopa (Parkinson's treatment), mycophenolate (immunosuppressant), and penicillamine (used for Wilson's disease). All of these require dose separation of at least 2 hours, and some need 4–6 hours.
Vitamin B12 has one Minor interaction: metformin, a common diabetes medication, can lower B12 levels with prolonged use. This product has no documented interactions with B12 itself.
Altogether, these interactions span 138 individual medications. Use the medication checker below to verify your exact prescriptions before starting this supplement.

For each ingredient in Vegan Complete Iron 25 mg 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.
Ferrochel
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.
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.
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.
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%.
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.
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.
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.
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.
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.
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.
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.
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%.
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.
Folic Acid
5-Fluorouracil
Theoretically, high doses of folic acid might increase the toxicity of 5-fluorouracil.
Increases in gastrointestinal side effects of 5-fluorouracil, such as stomatitis and diarrhea, have been described in two clinical studies when leucovorin, a form of folic acid, was administered with 5-fluorouracil.
Capecitabine (Xeloda)
Use of high-dose folic acid might contribute to capecitabine toxicity.
Clinical research suggests that higher serum folate levels are associated with an increased risk for moderate or severe toxicity during capecitabine-based treatment for colorectal cancer. Additionally, in one case report, taking folic acid 15 mg daily might have contributed to increased toxicity, including severe diarrhea, vomiting, edema, hand-foot syndrome, and eventually death, in a patient prescribed capecitabine.
Methotrexate (Trexall, Others)
Folic acid might reduce the efficacy of methotrexate as a cancer treatment when given concurrently.
Methotrexate exerts its cytotoxic effects by preventing conversion of folic acid to the active form needed by cells. There is some evidence that folic acid supplements reduce the efficacy of methotrexate in the treatment of acute lymphoblastic leukemia, and theoretically they could reduce its efficacy in the treatment of other cancers. Advise cancer patients to consult their oncologist before using folic acid supplements. In patients treated with long-term, low-dose methotrexate for rheumatoid arthritis (RA) or psoriasis, folic acid supplements can reduce the incidence of side effects, without reducing efficacy.
Phenobarbital (Luminal)
Folic acid might have antagonistic effects on phenobarbital and increase the risk for seizures.
Folic acid can have direct convulsant activity in some people, reversing the effects of phenobarbital and worsening seizure control. Monitor closely for increased seizure activity.
Phenytoin (Dilantin)
Folic acid might reduce serum levels of phenytoin in some patients.
Folic acid may be a cofactor in phenytoin metabolism. Folic acid, in doses of 1 mg daily or more, can reduce serum levels of phenytoin in some patients. Increases in seizure frequency have been reported. If folic acid supplements are added to established phenytoin therapy, monitor serum phenytoin levels closely. If phenytoin and folic acid are started at the same time and continued together, adverse changes in phenytoin pharmacokinetics are avoided. Note that phenytoin also reduces serum folate levels.
Primidone (Mysoline)
Folic acid might have antagonistic effects on primidone and increase the risk for seizures.
Folic acid can have direct convulsant activity in some people, reversing the effects of primidone and worsening seizure control. Monitor closely for increased seizure activity. Note that primidone also reduces serum folate levels.
Pyrimethamine (Daraprim)
Folic acid might antagonize the effects of pyrimethamine.
Folic acid can antagonize the antiparasitic effects of pyrimethamine against toxoplasmosis and Pneumocystis carinii pneumonia. Folic acid doesn't antagonize the effects of pyrimethamine in the treatment of malaria, because malarial parasites cannot use exogenous folic acid. Use folinic acid as an alternative to folic acid when indicated.
Vitamin B12
Metformin (Glucophage)
Metformin, a common medication used to manage type 2 diabetes, has been associated with lower vitamin B12 levels in some individuals. Prolonged use of metformin can interfere with the absorption of B12 in the digestive system, potentially leading to a deficiency in this essential vitamin.
