HelloPharmacist Scorecard of Slippery Elm 1000 mg by Nutricost

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.

Nutricost Slippery Elm contains one active ingredient: slippery elm bark extract at 1000 mg per capsule. Slippery elm is a traditional herbal remedy sourced from the inner bark of the slippery elm tree.

The capsule also holds inactive ingredients (hypromellose, magnesium stearate, and silica), which are standard binders and fillers.

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 Slippery Elm product and its label doesn't state a use — see Slippery Elm'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.

The evidence we have for slippery elm doesn't yet establish it as reliable for constipation, diarrhea, cough, inflammatory bowel disease (IBD), or cancer. Each of these uses carries a rating of insufficient reliable evidence — meaning the research to date isn't solid enough to say whether it works.

That doesn't mean it doesn't work; it means we don't have the high-quality studies to prove it does.

The evidence, ingredient by ingredient Slippery Elm

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.

Slippery elm is generally well tolerated in short-term use, though detailed safety data are limited. Some people may experience contact dermatitis (skin irritation) or hives if they touch the extract directly, and the pollen is a known allergen.

The safety data during pregnancy aren't robust enough to know either way — talk with your doctor or pharmacist for personalized advice if you're pregnant. There's too little information on safety while breastfeeding, so caution is advised; again, your own provider can weigh the pros and cons for your situation.

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 — Slippery Elm.
  • The most serious interaction on file is rated Moderate.
  • For scale: 2,023 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 oral medications of any kind, you'll need to check them specifically. Slippery elm's mucilage can slow their absorption and lower their blood levels.

Run each of your medications through the interaction checker on this page, and talk with your pharmacist or doctor about the best timing or whether to take them together at all.

The bottom line

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

Slippery Elm by Nutricost may be worth considering if you're interested in traditional herbal approaches, but the evidence for its effectiveness isn't established yet. The main caution is that it may slow how your body absorbs other oral medications.

Before you start, check your exact medications with your pharmacist or doctor — they can tell you whether timing matters or whether you should skip it altogether.

Slippery Elm 1000 mg by Nutricost: Common Questions

Does Slippery Elm 1000 mg by Nutricost interact with any medications?
Yes. Based on its ingredients, Slippery Elm 1000 mg has a known interaction with 2,022 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Slippery Elm 1000 mg contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism responsible.
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.
Does slippery elm really work for constipation or diarrhea?
The evidence we have isn't strong enough yet to say. Both constipation and diarrhea are listed as insufficient reliable evidence — meaning the research to date hasn't proven it works, though that doesn't mean people don't find it helpful. Your own doctor or pharmacist may have seen how it works in practice for their patients.
Can I take slippery elm if I'm pregnant?
There isn't enough reliable safety data to know either way during pregnancy. Some sources caution against it. Talk with your doctor or pharmacist — they can weigh your specific situation and help you decide whether to take it.
Is it safe to take while breastfeeding?
There's too little information on safety while breastfeeding to know. Caution is advised. Check with your doctor or pharmacist before starting, especially if you're nursing.
Can slippery elm cause side effects?
Slippery elm is generally well tolerated when taken by mouth. If you touch the extract directly, you may get contact dermatitis (skin irritation) or hives. The pollen is a known allergen, so avoid it if you're allergic to elm pollen.
Does this product have any fillers?
Yes — the capsule contains hypromellose, magnesium stearate, and silica as inactive ingredients. These are standard binders and fillers used in capsules; the active ingredient is slippery elm bark extract alone.
How should I time this if I'm on other medications?
Slippery elm's mucilage may slow how your body absorbs oral drugs. Your pharmacist or doctor can advise on the best timing — sometimes spacing doses a few hours apart helps, but it depends on your specific medications. Check with them before you start.
