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: madder root at 450 mg per capsule. Madder is a plant traditionally used in herbal medicine.

The capsule itself is made from gelatin and water.

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 Madder product and its label doesn't state a use — see Madder'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 don't have effectiveness ratings on file for madder root, so we can't tell you whether the evidence supports its use for any particular purpose.

The evidence, ingredient by ingredient Madder

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.

Madder comes with some real safety concerns you should know about. Some madder compounds have shown genotoxic effects (the ability to damage genetic material) and possible cancer-causing potential, so it's best avoided as a supplement.

The most common side effect is red-colored urine, saliva, and perspiration—harmless but noticeable. There's also concern that madder can stain contact lenses, so be cautious if you wear them.

Handling madder can cause contact dermatitis (skin irritation) in some people. Madder is unsafe during pregnancy because it has traditionally been used to stimulate menstruation and may affect the uterus.

It's also unsafe while breastfeeding because its safety isn't known and its pigments can pass into breast milk.

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 for madder in our data, so there are no medication types you need to double-check.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. No medication interactions are currently documented, and safety information is well characterized.

Given the genotoxic and possible cancer-causing concerns, madder root is not a supplement we'd recommend as a routine choice. If you're pregnant or breastfeeding, definitely skip it.

If you're considering it anyway, talk with your pharmacist or doctor first—this is one to discuss before starting.
