HelloPharmacist Scorecard of Mulberry Zuccarin by New Nordic

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.

Mulberry Zuccarin contains one active ingredient: white mulberry leaf extract, which has been used in traditional medicine and studied for potential effects on blood sugar and cholesterol levels. The tablet also includes inactive ingredients — dicalcium phosphate, microcrystalline cellulose, silicon dioxide, magnesium stearate, and hydroxypropyl methylcellulose — which are fillers and binders that give the tablet its form.

Does it work?

Not established
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 established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use — see White Mulberry's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: helps block sugar absorption.
  • We looked for evidence on: Diabetes, Impaired glucose tolerance (prediabetes), Postprandial glucose control, Glycemic management.
  • The closest evidence on file: White Mulberry is rated "Insufficient Reliable Evidence To Rate" for Diabetes (Natural Medicines).
  • Also on file: White Mulberry is rated "Insufficient Reliable Evidence To Rate" for Impaired glucose tolerance (prediabetes).

The evidence on white mulberry leaf for most of its traditional uses — including hair loss (androgenic alopecia), bone health (osteoporosis), cold symptoms, blood sugar control (diabetes), and cholesterol (hyperlipidemia) — is not established enough in the data we hold to rate it as effective. Clinical studies do show it can lower blood glucose in the short term, but whether that translates to real benefits for people with diabetes over the long run isn't clear from the information available.

The evidence, ingredient by ingredient White Mulberry

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.

White mulberry leaf powder seems to be well tolerated overall when taken orally. In one clinical trial using 4.6 grams three times daily, about half of participants experienced bloating and flatulence, a quarter had loose stools, and one-fifth had constipation — though these side effects were transient and decreased as the study went on, suggesting they may ease with continued use.

The safety data is not sufficient to recommend medicinal amounts (concentrated supplements, not the food form) during pregnancy or while breastfeeding. If you're pregnant or nursing, talk with your doctor or pharmacist about whether this product is right for you.

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 — White Mulberry.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: diabetes medications.
  • For scale: 87 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.

Before taking Mulberry Zuccarin, double-check with your own doctor or pharmacist if you take any antidiabetes drugs (such as metformin, insulin, or sulfonylureas) — white mulberry may increase the risk of low blood sugar (hypoglycemia). Also confirm any medications that are processed through the kidneys via an OCT2 transporter, as the mulberry leaf may slow their clearance and raise their levels.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

Mulberry Zuccarin may be worth considering if you're interested in traditional herbal support, but it's important to know it can lower blood sugar and may interact with diabetes medications and certain other drugs. If you take any prescription medication — especially for blood sugar control — check with your doctor or pharmacist before starting this product.

Gastrointestinal side effects are common at first but often improve over time.

Antidiabetes Drugs

Theoretically, white mulberry leaf might increase the risk of hypoglycemia when taken with antidiabetes drugs.
Clinical research shows that white mulberry leaf can lower blood glucose levels. Advise patients to monitor glucose levels closely.

Likelihood Possible Evidence D
Organic Cation Transporter 2 (Oct2) Substrates

Theoretically, white mulberry leaf might slow the elimination and increase the adverse effects of drugs which are OCT2 substrates.
Animal research shows that coadministration of white mulberry leaf extract with metformin, an OCT2 substrate, slows the renal elimination of metformin via inhibition of OCT2 activity. OCT2 is expressed in the kidneys and is responsible for transporting cationic drugs into tubular epithelial cells in order to be excreted in the urine.

Mulberry Zuccarin by New Nordic: Common Questions

Does Mulberry Zuccarin by New Nordic interact with any medications?
Yes. Based on its ingredients, Mulberry Zuccarin has a known interaction with 87 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Mulberry Zuccarin 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.
Will Mulberry Zuccarin lower my blood sugar if I don't have diabetes?
Yes — clinical research shows white mulberry leaf can lower blood glucose levels. If you don't have diabetes and don't take blood-sugar medications, this is less of a concern, but it's worth knowing. If you have any concern about your blood sugar, talk it over with your doctor or pharmacist.
What are the most common side effects?
Bloating, flatulence, loose stools, and constipation are the most common — though they tend to be temporary. In one study, about half of people taking a high dose experienced bloating and flatulence at first, but these effects decreased over the weeks of use, suggesting they may settle down.
Is it safe to take while pregnant or breastfeeding?
There isn't enough safety data on medicinal amounts of white mulberry to know either way. If you're pregnant or breastfeeding, talk with your doctor or pharmacist before starting this product.
Can I take this if I'm on metformin?
Animal research suggests white mulberry may slow how your body clears metformin, and the leaf can also lower blood sugar itself — so the combination needs careful oversight. Talk with your doctor or pharmacist before adding this product to your metformin regimen; they may want to monitor your blood sugar more closely.
Does white mulberry actually work for hair loss, bone health, or cholesterol?
The evidence we hold doesn't establish that it works for those uses. The strongest research shows it can lower blood glucose, but evidence for other benefits like hair regrowth, bone strength, or cholesterol control isn't solid enough for us to rate it as effective.
