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: Mexican wild yam (Dioscorea villosa) rhizome extract and wild yam (Dioscorea opposita) rhizome extract, both standardised for potency. These are plant extracts traditionally used to support hormonal balance, though the evidence for most uses is still being studied.

The remaining ingredients—rice bran and the capsule material—are inactive excipients.

Does it work?

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
Leans against

The strongest graded evidence we hold for the stated purpose leans against a benefit.

Why this rating?
  • The label markets this product for: menopausal symptoms and hormone balance.
  • We looked for evidence on: Menopausal symptoms, Postmenopausal conditions, Dysmenorrhea, Premenstrual syndrome (PMS), hormonal balance, menstrual health.
  • 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 in this product is limited. For menopausal symptoms, it's rated possibly ineffective.

For gallbladder disease, sexual dysfunction, menstrual cramps (dysmenorrhea), and infertility, there isn't enough reliable evidence to know whether it works. The data we hold doesn't establish that wild yam delivers the results people often hope for.

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, but long-term safety hasn't been well studied. The most common side effects 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.

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.

Before you take this product, double-check with your doctor or pharmacist if you're on any estrogen-based medication—including hormone replacement therapy and hormonal birth control pills. Wild yam may theoretically increase or decrease how these drugs work.
