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: Wahoo Bark Extract, Dry. The extract is delivered in a liquid form with alcohol, water, and glycerin as inactive ingredients.

Does it work?

Couldn't assess
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 assessable

This is a single-ingredient Wahoo product and its label doesn't state a use — see Wahoo's own graded uses on its monograph.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

We hold no effectiveness data for Wahoo Bark Extract in our records.

The evidence, ingredient by ingredient Wahoo

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.

Wahoo is considered poisonous and carries serious safety concerns. The safety notes in our data advise avoiding it — it is toxic and contains compounds that can cause life-threatening effects.

A single ingestion can trigger severe upset stomach with possible bloody diarrhea, fever, shortness of breath, circulatory collapse, unconsciousness, muscle spasms, and coma, sometimes within hours. During pregnancy and lactation, wahoo is rated likely unsafe.

Do not use this product if you are pregnant, trying to become pregnant, or breastfeeding.

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 — Wahoo.
  • The most serious interaction on file is rated Major.
  • Some involve high-stakes drug classes: heart-rhythm medications.
  • For scale: 133 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.

If you take digoxin (Lanoxin) for your heart, do not use this product — it is contraindicated. If you take diuretic drugs (water pills), stimulant laxatives, macrolide or tetracycline antibiotics, or quinine, check with your pharmacist before starting, as moderate interactions are documented.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Major medication interactions have been identified, and safety information is well characterized.

We cannot recommend Wahoo Bark Extract. The safety data describes it as poisonous with a history of serious, life-threatening toxicity.

The interaction profile is also complex and includes a major contraindication with digoxin. Talk with your pharmacist or doctor before considering any product containing wahoo.

No. Wahoo is rated likely unsafe during pregnancy and lactation. Do not use this product if you are pregnant, planning to become pregnant, or breastfeeding.
