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.

Does it work?

Insufficient evidence
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
Insufficient

There isn't enough reliable clinical evidence to rate this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: Cramp Bark for menstrual and muscle cramps.
  • We looked for evidence on: Dysmenorrhea, Muscle cramps, Pregnancy-related leg cramps, General cramping pain, Muscle spasms.
  • The closest evidence on file: Cramp Bark is rated "Insufficient Reliable Evidence To Rate" for Muscle cramps (Natural Medicines).
  • Also on file: Cramp Bark is rated "Insufficient Reliable Evidence To Rate" for Dysmenorrhea, Pregnancy-related leg cramps.

The evidence isn't established in the data we hold for any of cramp bark's common uses — including muscle cramps, period pain (dysmenorrhea), kidney stones, pregnancy-related leg cramps, or blood sugar support. We don't have reliable evidence one way or the other for these conditions.

How safe is it?

Some data gaps
Safety Information · database check
Some gaps

Safety data exists for these ingredients, but with some important gaps.

Why this rating?
  • We hold adverse-effect (side-effect) data for 0 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.

Cramp bark is generally well tolerated, but human safety data are limited since it's mainly been used in traditional medicine. The safety data advise against use during pregnancy and there isn't enough information to know if it's safe during breastfeeding.

If you're pregnant or breastfeeding, talk with your doctor or pharmacist about whether this product is right for you before starting it.
