HelloPharmacist Scorecard of Herbal Iron Formula by Christopher's Original Formulas
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 formula contains five active ingredients: yellow dock root, dandelion, beet, spirulina (a blue-green algae), and nettle. Each plays a traditional role in herbal iron support.
The capsule itself is plant-derived. Beyond these actives, there are no other added ingredients listed.
Does it work?
Not established
The evidence on this formula's ingredients is limited. Beet shows possibly effective evidence for athletic performance and exercise-related muscle soreness, but dandelion, yellow dock, nettle, and spirulina lack sufficient reliable evidence for their traditional uses—most are rated as having insufficient data to confirm they work for their intended purposes.
How safe is it?
Well-documented data
Yellow dock is generally well tolerated when properly prepared and used short-term, but it acts as a laxative and contains oxalates; the product advises caution and short-term use. The safety data advises against it during pregnancy and breastfeeding.
Dandelion as a food is widely eaten safely, though supplement-strength doses are less studied and may trigger allergy or stomach upset in sensitive people; data on breastfeeding safety is limited. Beet as a food is well tolerated, but concentrated supplements lack safety data.
Spirulina quality varies—some products carry contamination with toxins or heavy metals—and safety during pregnancy and breastfeeding is not established. Nettle is generally well tolerated as directed, but traditional concerns about uterine effects mean it's best avoided in pregnancy, and breastfeeding safety hasn't been established.
Across all ingredients, the most common side effects are digestive (diarrhea, constipation, stomach upset, bloating) and, rarely, allergic reactions.
Meds to double-check
Major interaction found
Before taking this product, check with your doctor or pharmacist if you take diuretic drugs (water pills)—yellow dock and nettle both may compound potassium loss or have additive effects. If you take digoxin (Lanoxin) for the heart, blood thinners or antiplatelet drugs (like warfarin or aspirin), diabetes medications, lithium, or fluoroquinolone antibiotics (like ciprofloxacin), these ingredients carry documented Moderate to Major interactions.
Also flag immunosuppressants and drugs metabolized by liver enzymes CYP1A2, CYP3A4, or UDP-glucuronosyltransferase. Your pharmacist can search your full medication list against this product.
The bottom line
Scorecard at a glanceFormula with limited ingredient disclosure with no established evidence rating for its marketed use. Major medication interactions have been identified, and safety information is well characterized.
This product is designed for iron support through traditional herbs, but the evidence that it works is not well established in our data. If you take any prescription medication—especially water pills, heart medications, blood thinners, diabetes drugs, lithium, antibiotics, or immunosuppressants—you need to check this product against your exact prescriptions with your doctor or pharmacist before starting.
Pregnant and breastfeeding people should also talk with their healthcare provider first, since safety data is limited or advises against use for several ingredients.

Herbal Iron Formula by Christopher's Original Formulas Drug Interactions
HelloPharmacist Interaction Report
Christopher's Original Formulas Herbal Iron Formula contains five ingredients—yellow dock, dandelion, beet, spirulina, and nettle—that together carry documented interactions with medications.
The most serious concern is yellow dock, which may increase the risk of potassium loss (hypokalemia) when combined with diuretic drugs (water pills), and could raise digoxin toxicity if used long-term or in large amounts—both Major-severity interactions.
Read the full breakdown — every affected drug type, severity by severity
Dandelion adds several Moderate-severity interactions: it may raise levels of drugs broken down by the liver enzyme CYP1A2, increase the risk of high potassium (hyperkalemia) with potassium-sparing diuretics, boost bleeding risk with blood thinners or antiplatelet drugs, lower blood sugar excessively with diabetes medications, speed up clearance of drugs processed through UDP-glucuronosyltransferase, raise lithium levels by reducing its excretion, and lower fluoroquinolone antibiotic levels. Beet may increase levels of CYP3A4 substrate drugs (a Moderate concern) and theoretically lower blood pressure or affect CYP1A2 substrates (both Minor).
Spirulina carries Moderate-severity interactions with blood thinners and antiplatelet drugs, immunosuppressants, and diabetes medications. Nettle adds Moderate concerns with diabetes drugs, diuretics, lithium, and warfarin.
Altogether, these interactions span 1,165 individual medications. Check your exact prescriptions and over-the-counter drugs using the tool on this page before starting this product.

For each ingredient in Herbal Iron Formula 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.
Beet
Cytochrome P450 3A4 (Cyp3A4) Substrates
Theoretically, beet might increase the levels of CYP3A4 substrates.
In vitro research suggests that betanin, the major pigment in beet, competitively inhibits CYP3A4 in a dose-dependent manner similarly to strong CYP3A4 inhibitor ketoconazole.
Antihypertensive Drugs
Beet and beetroot contain nitrates, which can cause vasodilation, potentially leading to lower blood pressure. However, a study published in the European Journal of Clinical Nutrition using concentrated beetroot juice found no significant impact on blood pressure or heart rate in different age groups. Other small clinical studies suggest that while beet consumption might transiently lower blood pressure due to vessel dilation, there's no consistent evidence of a lasting effect. Overall, the theoretical risk of reduced blood pressure due to beet's nitrate content exists, but studies generally indicate a low and temporary impact rather than a sustained decrease.
Cytochrome P450 1A2 (Cyp1A2) Substrates
Theoretically, beet might decrease the levels and clinical effects of CYP1A2 substrates.
In vitro research suggests that beet induces CYP1A2 enzymes.
Dandelion
Anticoagulant/Antiplatelet Drugs
Theoretically, taking dandelion root along with anticoagulant or antiplatelet drugs might increase the risk of bruising and bleeding.
In vitro research suggests that dandelion root inhibits platelet aggregation.
Antidiabetes Drugs
Theoretically, dandelion might increase the risk for hypoglycemia when used with antidiabetes drugs.
Laboratory research suggests that dandelion extract may have moderate alpha-glucosidase inhibitor activity and might also increase insulin secretion. Also, in a case report, a 58-year-old woman with type 2 diabetes who was being treated with insulin developed hypoglycemia 2 weeks after beginning to eat salads containing dandelion.
Cytochrome P450 1A2 (Cyp1A2) Substrates
Theoretically, dandelion might increase levels of drugs metabolized by CYP1A2.
Laboratory research suggests that dandelion might inhibit CYP1A2. So far, this interaction has not been reported in humans. However, until more is known, watch for an increase in the levels of drugs metabolized by CYP1A2 in patients taking dandelion.
Glucuronidated Drugs
Theoretically, dandelion might increase the clearance of drugs that are UDP-glucuronosyltransferase substrates.
There is some preliminary evidence that dandelion might induce UDP-glucuronosyltransferase, a phase II enzyme.
Lithium
Theoretically, through diuretic effects, dandelion might reduce excretion and increase levels of lithium.
Animal research suggests that dandelion has diuretic properties. As diuretics can increase serum lithium levels, the dose of lithium might need to be decreased when taken with dandelion.
Potassium-Sparing Diuretics
Theoretically, dandelion might increase the risk of hyperkalemia when taken with potassium-sparing diuretics.
Dandelion contains significant amounts of potassium.
Quinolone Antibiotics
Theoretically, dandelion might lower fluoroquinolone levels.
Animal research shows that dandelion reduces absorption of ciprofloxacin and can lower levels by 73%. However, this effect has not been reported in humans.
Spirulina
Anticoagulant/Antiplatelet Drugs
Theoretically, spirulina blue-green algae might increase the risk of bleeding if used with other anticoagulant or antiplatelet drugs. However, this is unlikely.
Spirulina blue-green algae have shown antiplatelet and anticoagulant effects in vitro. However, one preliminary study in 24 patients receiving spirulina blue-green algae 2.3 grams daily for 2 weeks showed no effect on platelet activation or measures of clotting time.
Antidiabetes Drugs
Theoretically, taking blue-green algae with antidiabetes drugs might increase the risk of hypoglycemia.
Human research shows that spirulina blue-green algae can have hypoglycemic effects in patients with diabetes, at least some of whom were using antidiabetes drugs. However, blue-green algae does not seem to improve glycated hemoglobin (HbA1c) levels in patients with diabetes. A meta-analysis of animal studies also suggests that spirulina blue-green algae have hypoglycemic effects.
Immunosuppressants
Theoretically, concurrent use of blue-green algae might interfere with immunosuppressive therapy.
Blue-green algae have been shown to stimulate the immune system.
Nettle
Antidiabetes Drugs
Theoretically, stinging nettle might have additive effects with antidiabetes drugs.
Clinical research shows that stinging nettle might decrease blood glucose levels in patients with diabetes.
Diuretic Drugs
Theoretically, combining stinging nettle with diuretic drugs may have additive effects.
Animal research suggests that the above ground parts and roots of stinging nettle may have a diuretic effect.
Lithium
Theoretically, stinging nettle might reduce excretion and increase levels of lithium.
Animal research suggests that stinging nettle has diuretic and natriuretic properties, which could alter the excretion of lithium. The dose of lithium might need to be decreased.
Warfarin (Coumadin)
There is some concern that stinging nettle might decrease the effects of anticoagulant drugs such as warfarin.
Stinging nettle contains a significant amount of vitamin K. When taken in large quantities, this might interfere with the activity of warfarin.
Yellow Dock
Digoxin (Lanoxin)
Theoretically, yellow dock might increase the risk of digoxin toxicity when used long-term or in large amount.
When yellow dock is used chronically or in large amounts, hypokalemia may occur. This might increase the toxic effects of digoxin.
Diuretic Drugs
Theoretically, yellow dock might increase the risk of hypokalemia when taken with diuretics.
When yellow dock is used chronically or in large amounts, hypokalemia may occur, and overuse of yellow dock might compound diuretic-induced potassium loss.
Warfarin (Coumadin)
Theoretically, the laxative effects of yellow dock might increase the effects of warfarin, including the risk of bleeding.
The anthraquinones in yellow dock have a mild stimulant laxative effect. Consuming excessive amounts can cause diarrhea. Diarrhea can increase the effects of warfarin, increase international normalized ratio (INR), and increase the risk of bleeding.
