HelloPharmacist Scorecard of Wild Yam Root 450 mg by Vitamin World

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 11, 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 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

This supplement contains one active ingredient: wild yam root at 450 mg per capsule. The capsule itself is made from gelatin and vegetable cellulose, which are inactive ingredients that hold the supplement together.

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 Wild Yam's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: Herbal supplement support.
  • We looked for evidence on: Menopausal symptoms, Dysmenorrhea, Premenstrual syndrome (PMS), Postmenopausal conditions, Hormone balance, Menstrual health — and 1 related terms.
  • The closest evidence on file: Wild Yam is rated "Possibly Ineffective" for Menopausal symptoms (Natural Medicines).
  • Also on file: Wild Yam is rated "Insufficient Reliable Evidence To Rate" for Postmenopausal conditions, Premenstrual syndrome (PMS), Dysmenorrhea.

The evidence for wild yam is limited. For menopausal symptoms, the data shows it's possibly ineffective—meaning studies haven't found it reliably helps.

For other uses listed here—gallbladder disease, sexual dysfunction, menstrual cramps, and infertility—there isn't enough reliable evidence yet to know whether it works.

The evidence, ingredient by ingredient Wild Yam

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.

Wild yam is generally well tolerated in the short term for healthy adults, though long-term safety isn't well studied. The most common side effects from oral use are fever, headache, upset stomach, and vomiting, especially at higher doses.

Rarely, anaphylaxis (a severe allergic reaction) has been reported. The safety data advises against use during pregnancy and while breastfeeding because there isn't enough information to know it's safe in those situations.

Side effects, ingredient by ingredient Wild Yam

Meds to double-check

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 — Wild Yam.
  • The most serious interaction on file is rated Moderate.
  • For scale: 41 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.

Check your exact estrogen-based medications—including hormone replacement therapy and hormonal birth control—before adding this product. Wild yam may interfere with how your body handles estrogen, so verify with your pharmacist that it's safe for you.

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.

If you're thinking about wild yam for menopausal symptoms or another reason, know that the evidence for it working is weak or missing. The bigger concern is if you take estrogen-based medications—this supplement might interfere with them.

Talk with your pharmacist before starting, especially if you're on hormone therapy or birth control.

Wild Yam Root 450 mg by Vitamin World: Common Questions

Does Wild Yam Root 450 mg by Vitamin World interact with any medications?
Yes. Based on its ingredients, Wild Yam Root 450 mg has a known interaction with 41 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Wild Yam Root 450 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.
Does wild yam actually help with hot flashes and night sweats?
The research shows it's possibly ineffective for menopausal symptoms, meaning studies haven't found it reliably works for that use. If you're looking for relief, talk with your doctor about options with better evidence.
What are the most common side effects?
Fever, headache, upset stomach, and vomiting are the side effects reported most often, especially when people take higher doses. These effects are generally mild, but rarely anaphylaxis (a severe allergic reaction) has occurred.
Can I take this while pregnant?
No—the safety data advises against it because there isn't enough information to know it's safe during pregnancy. Talk with your doctor or pharmacist before considering any supplement in pregnancy.
Can I take this while breastfeeding?
No—there isn't enough safety data to know it's safe while breastfeeding. The data advises you to avoid it during that time. Your doctor or pharmacist can discuss safer options with you.
What exactly is wild yam root?
Wild yam is a plant root used in traditional medicine. In lab studies, it shows both estrogenic (estrogen-like) and anti-estrogenic effects, which is why it can potentially interfere with estrogen-based medications.
