HelloPharmacist Scorecard of D-Mannose 1500 mg by NusaPure

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: D-mannose, a simple sugar (carbohydrate) that your body doesn't metabolize the way it does glucose. The capsule also holds rice flour, cellulose, and silica as inactive ingredients — those are fillers and binders that help hold the tablet together.

Does it work?

Strong 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
Strong

Clinical evidence supports at least one of this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: urinary tract health and infection prevention.
  • We looked for evidence on: Urinary tract infections (UTIs), Carbohydrate-deficient glycoprotein syndrome type 1b, urinary tract function, cystitis.
  • The strongest evidence on file: D-mannose is rated "Likely Effective" for Carbohydrate-deficient glycoprotein syndrome type 1b (Natural Medicines).
  • Also on file: D-mannose is rated "Possibly Ineffective" for Urinary tract infections (UTIs).

D-mannose is likely effective for carbohydrate-deficient glycoprotein syndrome type 1b, a rare genetic condition. For urinary tract infections (UTIs), however, the evidence suggests it's possibly ineffective — so this product isn't a proven option if that's what you're after.

The evidence, ingredient by ingredient D-mannose

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.

D-mannose is generally well tolerated over the short term, but we don't have high-quality long-term safety data, so it's best not to take it unless your doctor advises otherwise. The most common side effects are bloating, diarrhea, and nausea.

Loose stools and abdominal bloating show up most often, especially at higher doses — doses over 200 mg per kilogram of body weight make osmotic diarrhea (the kind caused by unabsorbed sugars) more likely. Safety while breastfeeding isn't well studied, so caution is advised if you're nursing.

Pregnancy safety data aren't on file for this ingredient, so there isn't enough information to know either way. Talk with your doctor or pharmacist about whether it's right for you if you're pregnant or planning to be.

Side effects, ingredient by ingredient D-mannose

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 D-mannose. That doesn't mean they can't happen — it just means we have no monograph entries showing them.

Run your medications through the search tool here, and if you're on anything regularly, check with your own doctor or pharmacist before you start.

The bottom line

Scorecard at a glanceFully disclosed formula with clinical evidence supporting its stated purpose. No medication interactions are currently documented, and safety information is well characterized.

D-mannose may be worth considering if you have carbohydrate-deficient glycoprotein syndrome type 1b and your doctor recommends it — that's where the evidence is strongest. If you're taking it for UTIs, the data don't support that use.

Most people tolerate it okay short-term, but bloating and diarrhea are common, and long-term safety isn't well established. Talk with your doctor or pharmacist before starting, especially if you're pregnant, breastfeeding, or have a condition that makes diarrhea a concern.

D-Mannose 1500 mg by NusaPure: Common Questions

Does D-Mannose 1500 mg by NusaPure interact with any medications?
We do not currently list a known interaction for the mapped ingredients in D-Mannose 1500 mg. This does not guarantee none exist, so confirm with your pharmacist.
How can one product interact with so many drugs?
D-Mannose 1500 mg contains 2 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is 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.
Will D-mannose cause diarrhea?
Bloating, diarrhea, and nausea are the most common side effects. Diarrhea is more likely at higher doses — especially if you take more than 200 mg per kilogram of body weight in a single dose. Starting lower and taking it with food may help, but talk with your pharmacist if loose stools become a problem.
Is D-mannose safe long-term?
It's generally well tolerated short-term, but high-quality long-term safety data are limited. That's why it's best not to take it unless your doctor advises otherwise. If you're thinking of taking it for months, definitely discuss that with your healthcare provider first.
Can I take this while breastfeeding?
Safety while breastfeeding isn't well studied, so caution is advised. There isn't enough data to know either way, so talk with your doctor or pharmacist before taking it while you're nursing.
Does D-mannose actually work for urinary tract infections?
The evidence suggests it's possibly ineffective for UTIs, so this product isn't a proven option for that use. If you're dealing with a UTI, check with your doctor about treatments that do have solid evidence behind them.
What is D-mannose?
D-mannose is a simple sugar that your body handles differently than regular glucose. It's found naturally in some fruits and is sometimes used as a supplement, though the evidence for most uses is limited.
