HelloPharmacist Scorecard of Iron Liquid by Pure Encapsulations
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
This product contains 3 active ingredients: iron, blueberry fruit extract (wild), and cranberry fruit extract, combined in a proprietary blend called CranBlue. The iron supports red blood cell production and oxygen transport; the fruit extracts are added for their antioxidant profile.
The liquid is made with water, glycerin, apple juice concentrate, and a handful of stabilizers and flavorings to improve taste and texture.
Does it work?
Strong evidence
Iron is effective for iron deficiency anemia, anemia from chronic disease, and pregnancy-related iron deficiency. Heart failure shows possibly effective evidence.
The blueberry extract in this product has no reliable evidence to support use for age-related cognitive decline, anxiety, athletic performance, or cholesterol — and it's rated possibly ineffective for high blood pressure. Cranberry extract is possibly effective for urinary tract infections but has insufficient evidence for cognitive decline, prostate health, cancer prevention, liver disease, or fatigue.
The evidence supporting the fruit extracts in this formula is limited.
How safe is it?
Well-documented data
Iron is generally well tolerated at recommended doses, though excess iron can be toxic — supplements should only be used when there's a genuine need. Common side effects include stomach pain, constipation, diarrhea, nausea, and vomiting.
Both blueberry and cranberry are likely safe in pregnancy and while breastfeeding; concentrated supplement doses of blueberry haven't been well studied in these periods, so check with your prenatal care provider or pharmacist first. Freeze-dried blueberries in particular have caused gastrointestinal upset (constipation, diarrhea, nausea, vomiting) in a significant number of trial participants — about a quarter of one study group dropped out within the first week due to stomach complaints.
Meds to double-check
Moderate interaction found
Before taking this product, double-check your medications for tetracycline antibiotics (doxycycline, minocycline), quinolone antibiotics (ciprofloxacin, levofloxacin), bisphosphonates (alendronate), blood pressure drugs like methyldopa or nifedipine, Parkinson's medication levodopa, thyroid hormone levothyroxine, the statin atorvastatin, blood thinner warfarin, the immunosuppressant mycophenolate mofetil, and penicillamine. Moderate-severity interactions exist for all of these; most require at least 2 hours' dose separation.
The bottom line
Scorecard at a glanceFormula with limited ingredient disclosure with clinical evidence supporting its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.
This is an iron supplement with added fruit extracts aimed at people who need iron replacement for anemia or pregnancy-related deficiency. Because iron interacts with multiple antibiotics, bone medications, blood thinners, and other drugs — and the fruit extracts add further interactions — you'll need to review your full medication list with your doctor or pharmacist before taking it.
Iron works best when your body actually needs it, so talk with your provider about whether supplementation is right for you and how to time doses around your other medications.

Iron Liquid by Pure Encapsulations Drug Interactions
HelloPharmacist Interaction Report
Iron Liquid by Pure Encapsulations contains iron, blueberry fruit extract, and cranberry fruit extract, and it has documented interactions with a substantial number of medications.
The most serious interaction is iron's ability to reduce the absorption of tetracycline antibiotics (such as doxycycline and minocycline) — a Moderate severity effect that can cut absorption by 50% to 90%, potentially undermining treatment.
Read the full breakdown — every affected drug type, severity by severity
Iron also interacts with several other drug types at Moderate severity. It can reduce absorption of quinolone antibiotics (like ciprofloxacin), bisphosphonates (osteoporosis medications), blood pressure medication methyldopa, Parkinson's drug levodopa, thyroid medication levothyroxine, the immunosuppressant mycophenolate mofetil, and the heavy-metal chelator penicillamine.
Each requires dose separation by 2 to 6 hours to minimize the effect.
Cranberry extract adds Moderate-severity interactions with drugs processed through the liver enzyme CYP3A4 — including the statin atorvastatin and the blood pressure medication nifedipine — and with the blood thinner warfarin, though evidence on warfarin is conflicting. Blueberry extract carries Minor-severity interactions with certain diabetes drugs (risk of low blood sugar), the pain reliever flurbiprofen, and the anxiety medication buspirone.
We could not check the CranBlue proprietary blend itself, since its exact composition is not available.
Altogether, these interactions span 853 individual medications. Before starting this product, check your exact prescriptions with your doctor or pharmacist.

For each ingredient in Iron Liquid 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.
Cranberry Fruit Extract
Atorvastatin (Lipitor)
Theoretically, cranberry might increase levels and adverse effects of atorvastatin.
In one case report, a patient taking atorvastatin experienced upper back pain, rhabdomyolysis, and abnormal liver function after drinking cranberry juice 16 ounces daily for 2 weeks. Theoretically, this may have been caused by inhibition of cytochrome P450 3A4 (CYP3A4) enzymes by cranberry juice, as atorvastatin is a CYP3A4 substrate. Creatinine kinase and liver enzymes normalized within 2 weeks of stopping cranberry juice. Patients taking atorvastatin should avoid large quantities of cranberry juice.
Cytochrome P450 3A4 (Cyp3A4) Substrates
Theoretically, cranberry might increase the levels and adverse effects of CYP3A4 substrates.
A case of upper back pain, rhabdomyolysis, and abnormal liver function has been reported for a patient taking atorvastatin, a CYP3A4 substrate, in combination with cranberry juice 16 ounces daily for 2 weeks. Creatinine kinase and liver enzymes normalized within 2 weeks of stopping cranberry juice. Also, animal research suggests that cranberry juice, administered intraduodenally 30 minutes prior to nifedipine, a CYP3A4 substrate, inhibits nifedipine metabolism and increases the area under the concentration-time curve by 1.6-fold compared to control.
Nifedipine (Procardia)
Theoretically, cranberry might increase the levels and adverse effects of nifedipine.
Animal research suggests that cranberry juice, administered intraduodenally 30 minutes prior to nifedipine treatment, inhibits nifedipine metabolism and increases the area under the concentration-time curve by 1.6-fold compared to control. This interaction has not been reported in humans.
Warfarin (Coumadin)
Theoretically, cranberry might increase the levels and adverse effects of warfarin. However, research is conflicting.
There is contradictory evidence about the effect of cranberry juice on warfarin. Case reports have linked cranberry juice consumption to increases in the international normalized ratio (INR) in patients taking warfarin, resulting in severe spontaneous bleeding and excessive postoperative bleeding. Daily consumption of cranberry sauce for one week has also been linked to an increase in INR in one case report. In a small study in healthy young males, taking a high dose of 3 grams of cranberry juice concentrate capsules, equivalent to 57 grams of fruit daily, for 2 weeks produced a 30% increase in the area under the INR-time curve after a single 25-mg dose of warfarin. However, 3 very small clinical studies in patients stabilized on warfarin reported that cranberry juice 250 mL once or twice daily for 7 days (27% cranberry juice or pure cranberry juice) or 240 mL once daily for 14 days does not significantly increase INR or affect plasma warfarin levels. The reasons for these discrepant findings are unclear. It is possible that the form and dose of cranberry may play a role, as cranberry extracts and juices contain different constituents. Additionally, an in vitro study evaluating 5 different cranberry juices found varying effects, with only a cranberry concentrate, and not diluted cranberry juices, inhibiting CYP2C9. However, this concentrate did not inhibit CYP2C9 activity in humans.
Cytochrome P450 2C9 (Cyp2C9) Substrates
Theoretically, cranberry might increase the levels and adverse effects of CYP2C9 substrates. However, research is conflicting.
There is contradictory evidence about the effect of cranberry on CYP2C9 enzymes. In vitro evidence suggests that flavonoids in cranberry inhibit CYP2C9 enzymes. However, clinical research shows that cranberry juice does not significantly affect the levels, metabolism, or elimination of the CYP2C9 substrates flurbiprofen or diclofenac. Also, in patients stabilized on warfarin, drinking cranberry juice 250 mL daily for 7 days does not significantly increase the anticoagulant activity of warfarin, a CYP2C9 substrate. Additional pharmacokinetic research shows that cranberry juice does not increase peak plasma concentrations or area under the concentration-time curve of warfarin.
Diclofenac (Voltaren, Others)
Theoretically, cranberry might modestly increase the levels and adverse effects of diclofenac.
In vitro evidence suggests that cranberry juice inhibits diclofenac metabolism by human liver microsomes. However, drinking cranberry juice does not seem to affect diclofenac metabolism in humans.
Blueberry Fruit Extract, Wild
Antidiabetes Drugs
Theoretically, blueberries or blueberry leaf extracts might increase the risk of hypoglycemia when taken with antidiabetes drugs.
Animal and in vitro research suggests that blueberry and/or blueberry leaf extracts can lower blood glucose levels.
Buspirone (Buspar)
Theoretically, blueberry juice might increase blood levels of buspirone.
In vitro research shows that blueberry juice can inhibit the metabolism of buspirone, possibly by inhibiting cytochrome P450 3A (CYP3A) enzymes. However, pharmacokinetic research in humans shows that drinking 300 mL of blueberry juice 30 minutes before taking buspirone hydrochloride 10 mg does not significantly affect the concentration or clearance of buspirone.
Flurbiprofen (Ansaid, Others)
Theoretically, blueberry juice might increase blood levels of flurbiprofen.
In vitro research shows that blueberry juice can inhibit the metabolism of flurbiprofen, possibly by inhibiting cytochrome P450 2C9 (CYP2C9) enzymes. However, pharmacokinetic research in humans shows that drinking 300 mL of blueberry juice 30 minutes before taking flurbiprofen 100 mg does not significantly affect the concentration or clearance of flurbiprofen.
Iron
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.
