HelloPharmacist Scorecard of Dandelion Root Extract by Natural Factors HerbalFactors

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.

From our pharmacy team — supplement deep dive

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Jul 23, 2026

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 2 of its 2 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains 2 active ingredients, both forms of dandelion — dandelion root and dandelion (Taraxacum officinale) extract. The inactive ingredients are a vegetarian capsule, magnesium stearate, and silica.

Does it work?

Not established
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
Not established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use — see Dandelion's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: enhance digestion and support liver gallbladder.
  • We looked for evidence on: Dyspepsia, Bile flow, Hepatic function, Cholecystokinin stimulation.
  • The closest evidence on file: Dandelion is rated "Insufficient Reliable Evidence To Rate" for Dyspepsia (Natural Medicines).

The evidence we hold doesn't establish how well dandelion works for the conditions listed — joint pain, tonsillitis, postoperative swelling, and postoperative pain all fall under insufficient reliable evidence to rate. That doesn't mean it doesn't work; it means the research data supporting these uses isn't solid enough for us to make a claim.

The evidence, ingredient by ingredient Dandelion

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 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Orally, dandelion is generally well tolerated, though supplement-strength doses are less studied than dandelion as a food. The most common side effects are diarrhea, heartburn, and stomach discomfort.

Rare serious reactions include anaphylaxis in sensitive people, and allergic reactions (including anaphylaxis, asthma, and allergic rhinitis) can occur if you're sensitive to dandelion pollen or to the ragweed family (Asteraceae/Compositae), which includes ragweed, daisies, marigolds, and chrysanthemums. There isn't enough reliable information on safety while breastfeeding, so talk with your doctor or pharmacist before using this supplement if you're nursing.

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?
  • 1 of the 1 matched ingredient can interact with medications — Dandelion.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications; lithium.
  • For scale: 457 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 this product, double-check with your doctor or pharmacist if you take blood thinners or antiplatelet drugs (risk of bleeding), diabetes medications (risk of low blood sugar), potassium-sparing water pills, lithium, fluoroquinolone antibiotics like ciprofloxacin, or drugs metabolized by CYP1A2 or UDP-glucuronosyltransferase enzymes. These are the main medication types documented to interact with dandelion.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

Dandelion root extract is generally well tolerated as a food, but supplement doses are less studied. The bigger question is whether it interacts with your medications — especially blood thinners, diabetes drugs, water pills, lithium, or certain antibiotics.

Before you start, check your exact medications with your doctor or pharmacist.

Dandelion7 drug types · 457 drugs

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.

Likelihood Possible Evidence D
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.

Likelihood Possible Evidence D
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.

Likelihood Possible Evidence D
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.

Likelihood Possible Evidence D
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.

Likelihood Probable Evidence D
Potassium-Sparing Diuretics

Theoretically, dandelion might increase the risk of hyperkalemia when taken with potassium-sparing diuretics.
Dandelion contains significant amounts of potassium.

Likelihood Possible Evidence D
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.
