HelloPharmacist Scorecard of Cramp Bark Alcohol Free by Hawaii Pharm

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

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: cramp bark bark extract (dry form). Cramp bark has a long history in traditional medicine, though the product itself is alcohol-free — the extract is suspended in glycerin and water instead.

The inactive ingredients are glycerin and water, which serve as the liquid base and preservative.

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: support for muscle and menstrual cramps.
  • We looked for evidence on: Dysmenorrhea, Muscle cramps, Pregnancy-related leg cramps, menstrual pain, skeletal muscle tension.
  • 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 for cramp bark isn't established yet in the data we hold. It's been used traditionally for muscle cramps, dysmenorrhea (menstrual pain), pregnancy-related leg cramps, kidney stones, and diabetes — but the research to confirm whether it actually works for any of these is insufficient.

That doesn't mean it doesn't work; it means human studies are either absent or too limited to draw solid conclusions.

The evidence, ingredient by ingredient Cramp Bark

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.

Human safety data on cramp bark are limited. The product carries a caution that it's been used in traditional medicine but we don't have enough safety information from clinical trials.

During pregnancy, the safety data advise against it — so it's best avoided if you're pregnant. For breastfeeding, there isn't enough information to know either way; talk with your doctor or pharmacist for personalized advice.

No adverse effects are listed in our data, though that reflects sparse trial reporting rather than a guarantee of safety.

Meds to double-check

No known interactions
Known Interaction Concern · database check
No known interactions

No medication interactions are currently documented for the matched ingredients — that isn't a guarantee none exist.

Why this rating?
  • None of the 1 matched ingredient has a documented medication interaction on file.

No interactions are documented in our data for the ingredient in this product. That absence doesn't guarantee none exist, so if you take any medications, it's still worth a quick check with your pharmacist or doctor before you start.

The bottom line

Scorecard at a glanceFully disclosed formula with insufficient evidence for its stated purpose. No medication interactions are currently documented, and some safety-information gaps remain.

Cramp Bark Alcohol Free is a single-ingredient extract with a long traditional use but limited human safety and effectiveness research. It's generally well tolerated based on the data we hold, though safety during pregnancy is a concern.

If you're considering it for muscle cramps, period pain, leg cramps, or another reason, check in with your doctor or pharmacist — they can help you weigh whether the evidence and your health picture make sense for you.

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.

There isn't enough safety information to know either way. Talk with your doctor or pharmacist — they can help you decide whether it's right for you while nursing.

Traditionally, it's been used for muscle cramps, menstrual pain, pregnancy-related leg cramps, kidney stones, and diabetes — though reliable evidence supporting these uses is insufficient.
