HelloPharmacist Scorecard of Dong Quai 565 mg by Nutricost

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
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 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains one active ingredient: Dong Quai (565 mg per capsule), a root used traditionally in Chinese medicine. The capsules also contain two inactive ingredients — hypromellose and silica — which are a capsule coating and anti-caking agent, respectively.

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 Dong Quai's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: women's health and menstrual cycle support.
  • We looked for evidence on: Dysmenorrhea, Menopausal symptoms, Premenstrual syndrome (PMS), irregular menstruation, hormonal balance.
  • The closest evidence on file: Dong Quai is rated "Insufficient Reliable Evidence To Rate" for Menopausal symptoms (Natural Medicines).
  • Also on file: Dong Quai is rated "Insufficient Reliable Evidence To Rate" for Premenstrual syndrome (PMS), Dysmenorrhea.

The data we hold shows insufficient reliable evidence to rate dong quai for any of its common uses: iron deficiency anemia, osteoporosis, heart disease, migraine headache, and atopic dermatitis (eczema). While it has a long history of traditional use, we don't have enough rigorous research to say whether it actually works for these conditions.

The evidence, ingredient by ingredient Dong Quai

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.

Dong quai is generally well tolerated when taken by mouth, though some people experience burping and flatulence. It may increase your bleeding risk and can make your skin more sensitive to sunlight, so use it with care and protect yourself from prolonged sun exposure.

The safety data advises against use during pregnancy because it may stimulate the uterus and affect bleeding. There isn't enough safety information to recommend it while breastfeeding — talk with your doctor or pharmacist about whether it's right for you if you're nursing.

Rarely, occupational exposure to dong quai has triggered allergic asthma and rhinitis in sensitive individuals. Dong quai contains compounds with carcinogenic properties; whether the amounts in this supplement are high enough to pose a cancer risk with long-term or high-dose use is unknown.

Side effects, ingredient by ingredient Dong Quai

Meds to double-check

Major interaction found
Known Interaction Concern · database check
Major identified

At least one ingredient has a documented Major-severity interaction. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Dong Quai.
  • The most serious interaction on file is rated Major.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs.
  • For scale: 163 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 Dong Quai 565 mg, double-check with your doctor or pharmacist if you take warfarin (Coumadin) or any other blood thinners or antiplatelet drugs — this is the highest-risk category. Also mention any estrogen-based medications or hormone replacement therapy, as dong quai may reduce their effectiveness.

The bottom line

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

Dong Quai may appeal to you if you're exploring traditional remedies for anemia, bone health, or migraines, but keep in mind that we don't have strong evidence it works for these uses. This supplement is not for you if you take warfarin, other blood thinners, or hormone medications — the bleeding and interaction risks are real and documented.

If you're pregnant or breastfeeding, avoid it. Talk with your own doctor or pharmacist before starting, especially if you take any prescription medications.

Dong Quai3 drug types · 163 drugs

Warfarin (Coumadin)

Dong quai may increase the risk of bleeding when used with warfarin.
Case reports suggest that concomitant use of dong quai with warfarin can increase the anticoagulant effects of warfarin and increase the risk of bleeding. In one case, after 4 weeks of taking dong quai 565 mg once or twice daily, the international normalized ratio (INR) increased to 4.9. The INR normalized 4 weeks after discontinuation of dong quai.

Likelihood Probable Evidence D
Anticoagulant/Antiplatelet Drugs

Theoretically, dong quai may increase the risk of bleeding when used with anticoagulant or antiplatelet drugs; however, research is conflicting.
Animal studies suggest that dong quai has antithrombin activity and inhibits platelet aggregation due to its coumarin components. Additionally, some case reports in humans suggest that dong quai can increase the anticoagulant effects of warfarin. However, clinical research in healthy adults shows that taking 1 gram of dong quai root daily for 3 weeks does not significantly inhibit platelet aggregation or cause bleeding. Until more is known, use dong quai with caution in patients taking antiplatelet/anticoagulant drugs.

Likelihood Possible Evidence D
Estrogens

Theoretically, dong quai may reduce the effects of estrogens.
Dong quai has estrogenic effects. Theoretically, concomitant use of large amounts of dong quai might interfere with hormone replacement therapy due to competition for estrogen receptors.

Dong Quai 565 mg by Nutricost: Common Questions

Does Dong Quai 565 mg by Nutricost interact with any medications?
Yes. Based on its ingredients, Dong Quai 565 mg has a known interaction with 163 medications, including 2 rated major. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Dong Quai 565 mg contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism 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.
Can I take this if I'm pregnant?
No. The safety data rates dong quai as possibly unsafe in pregnancy because it may stimulate the uterus and affect bleeding. Avoid it while pregnant and talk with your doctor or pharmacist about whether it's appropriate for you.
Can I take this while breastfeeding?
There isn't enough safety information to recommend dong quai while breastfeeding. Talk with your doctor or pharmacist to decide what's right for you and your baby.
What are the most common side effects?
When taken by mouth, dong quai is generally well tolerated. The most common side effects are burping and flatulence. It may also make your skin more sensitive to sunlight, so protect yourself from prolonged sun exposure if you take it.
Does dong quai actually work for anemia, osteoporosis, or migraines?
The evidence we hold doesn't establish that it works for any of these conditions — the data is rated insufficient. While dong quai has a long traditional history, we don't have enough rigorous research to say whether it actually helps.
Can I take this with birth control?
You should check with your doctor or pharmacist first. Dong quai has estrogenic effects and may theoretically interfere with hormone-based birth control by competing for estrogen receptors in your body.
