HelloPharmacist Scorecard of Mulberry Leaf 1000 mg by tnvitamins

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

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Aug 27, 2026

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.
  • “Mulberry” is listed as a grouped ingredient — the label gives one combined amount (1,000 mg) without saying how much of each component you get.

This product contains one active ingredient: white mulberry leaf extract at a 4:1 concentration (meaning four parts of the plant material are concentrated into one part of extract). The inactive ingredients are gelatin capsule, rice powder, and vegetable magnesium stearate.

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 White Mulberry product and its label doesn't state a use — see White Mulberry'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 for white mulberry leaf is limited. We hold insufficient reliable evidence to rate it for androgenic alopecia (hair loss), osteoporosis, common cold, diabetes, or high cholesterol.

Clinical research does show it can lower blood sugar levels, but whether that translates to a meaningful benefit for people with diabetes hasn't been established well enough for us to make a claim.

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.

Orally, white mulberry leaf is generally well tolerated. The most common side effects in trials were transient bloating, constipation, flatulence, and loose stools — but these tended to ease up over time as people continued taking it.

One clinical study found bloating and gas in about half of participants, loose stools in a quarter, and constipation in one-fifth, though symptoms decreased by week 12. Because concentrated supplements are less studied than the whole food, and because mulberry can lower blood sugar, caution is warranted.

We don't hold enough safety data to recommend medicinal amounts during pregnancy or breastfeeding — talk with your doctor or pharmacist about whether this product is right for you if you're pregnant or nursing.

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 — 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 you take this product, check with your doctor or pharmacist if you take antidiabetes drugs like metformin, glipizide, or any other blood sugar medication — mulberry can lower glucose and raise the risk of low blood sugar. Also check if you take any OCT2 substrates, which rely on kidney function for clearance; mulberry may slow their elimination.

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.

Mulberry leaf may be worth considering if you're interested in its traditional uses, but evidence for specific health claims is thin. The real caution is if you take diabetes medications or certain kidney-filtered drugs — you'll want to check your exact medications before starting.

Talk with your doctor or pharmacist to make sure this product won't lower your blood sugar too much or interfere with how your body clears your other drugs.

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 Leaf 1000 mg by tnvitamins: Common Questions

Does Mulberry Leaf 1000 mg by tnvitamins interact with any medications?
Yes. Based on its ingredients, Mulberry Leaf 1000 mg 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 Leaf 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.
What are the main side effects?
Bloating, gas, loose stools, and constipation are the most common — about half of people in a trial experienced bloating and gas, a quarter had loose stools, and one-fifth had constipation. The good news is these often ease up over a few weeks as your body adjusts.
Can I take this if I'm pregnant or breastfeeding?
We don't hold enough safety data on medicinal amounts to recommend it during pregnancy or breastfeeding. Talk with your doctor or pharmacist — they can help you weigh what you know about your situation against what we don't yet know.
Does mulberry leaf actually work for diabetes?
Clinical research shows mulberry can lower blood sugar levels, but we don't have reliable evidence it helps treat diabetes itself. Because it lowers glucose, it's especially important to monitor blood sugar closely if you take diabetes medication alongside it.
Is this safe to take long-term?
Mulberry leaf is likely safe as a food, but concentrated supplements like this one are less studied over long periods. The most common concern is the risk of low blood sugar if you take diabetes drugs — that's something to discuss with your doctor or pharmacist.
What is the white mulberry extract?
It's a concentrated form of white mulberry leaf — the 4:1 ratio means four parts of the plant material have been condensed into one part of extract, making it more potent than whole-leaf powder.
