Drug & supplement interaction

White Mulberry + Nadolol

Nadolol brand names: Corgard, Nadolol.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 13, 2026
The bottom line No known interaction

We found no known interaction between White Mulberry and Nadolol in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first. Additionally, although there is no interaction, the two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.

White Mulberry and Nadolol

We checked these two against our interaction database. Here is what we found.

No Known Interaction Found

We did not find a documented interaction between Nadolol and White Mulberry in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.

If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.

Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

White Mulberry safety at a glance

White Mulberry overall Use caution Likely safe as a food, but concentrated supplements are less studied and may lower blood sugar.
Pregnancy Avoid Not enough safety data; avoid medicinal amounts during pregnancy.
Breastfeeding Avoid Not enough safety data; avoid medicinal amounts while breastfeeding.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

Pharmacist analysis

White mulberry is not known to have many clinically significant drug interactions.

While our drug-herb interaction checker does list potential interactions with antidiabetic drugs and drugs that are affected by a protein known as OCT2, it is generally thought these are clinically insignificant for most individuals as they are theoretical and have not been seen in humans.

Nevertheless, it is important to be cautious if you take any drug that our tool shows an interaction for.

How we checked

Why No Interaction Is Listed for Nadolol

Interactions in our licensed database are recorded against drug classes, not just single drug names. Nadolol is filed under 5 classifications — including beta-blockers, antihypertensive drugs, seizure threshold lowering drugs. White Mulberry has documented interactions with 2 drug classes — the most serious being antidiabetes drugs (moderate) and organic cation transporter 2 (oct2) substrates (moderate) — and none of Nadolol’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

What to actually watch for

No Interaction Found — But Data Suggests White Mulberry and Nadolol May Share Several of the Same Side Effects

This is not an interaction. Neither one changes how your body handles the other, and nothing here says they react together. What our sources do show is that each has separately been linked to the effects below — so taking both can make those effects more likely to turn up, and harder to pin on one or the other if they do.

  • Bloating or gas / Constipation / Diarrhea reported in 5.9% of FDA reports for Nadolol Additional detail

    White Mulberry

    “Orally, white mulberry leaf powder 4.6 grams three times daily for 4 weeks was associated with bloating and flatulence in 50% of patients, loose stools in 25% of patients, and constipation in 21% of patients in one clinical study. However, reports of these adverse effects decreased over the course of the 12-week study, suggesting that for some patients the adverse effects may be transient in nature.”

    Listed in the ADVERSE REACTIONS section of the FDA label for Nadolol, and in voluntary FDA adverse-event reports. Read the label on DailyMed ›

Effects for Nadolol come from the ADVERSE REACTIONS section of its FDA label; effects for White Mulberry come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 7,530 voluntary FDA FAERS reports for Nadolol that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

Overlapping uses

What Nadolol Is Prescribed For, and What White Mulberry Has Been Studied For

These two come up together because they touch the same health topic — not because they do the same job. Nadolol is a prescription medicine with approved uses on its FDA label. White Mulberry is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.

Nadolol is prescribed for: Nadolol tablets are used for two main conditions: high blood pressure (hypertension) and angina pectoris (ongoing chest pain caused by reduced blood flow to the heart). Lowering high blood pressure reduces the risk of stroke and heart attack. For high blood pressure, nadolol may be prescribed on its own or combined with other blood pressure medications, especially thiazide-type diuretics (water pills). For angina, it is used for long-term management to help reduce how often chest pain occurs.

White Mulberry has been studied for:

  • Hypertension studied, not established White Mulberry has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

    White Mulberry for hypertension

    Although there has been interest in using oral white mulberry for hypertension, there is insufficient reliable evidence about the clinical effects of white mulberry for this purpose.

Effectiveness ratings and the research summaries above are the verbatim record from the Natural Medicines database, which grades evidence from “Effective” down to “Insufficient Reliable Evidence To Rate”. A rating below the top of that scale means researchers have looked at it — not that it works, and never that it can stand in for a prescribed medicine. Do not stop or replace Nadolol on your own; if you are taking White Mulberry for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

From our pharmacist’s overview on the Nadolol page

“If you take nadolol (Corgard) for blood pressure, angina, or heart rhythm, treat this list with real care, and green tea is the surprise at the top. In a clinical study, green tea cut nadolol blood levels by roughly 85 percent, which can quietly leave you undertreated.”

About White Mulberry

What is White Mulberry?

White Mulberry
  • Blood sugar support
  • High cholesterol
  • Weight management
  • Antioxidant support
  • High blood pressure (traditional use)

White mulberry leaf is most studied for helping blunt the rise in blood sugar after meals, but the human evidence is limited and not strong. It is generally well tolerated as a food and tea, but talk to your pharmacist or doctor before using concentrated supplements, especially if you take diabetes medicine.

Morus alba · Moraceae · Leaves, fruit (berries), root bark, and twigs · Capsules, tablets, leaf tea, powdered leaf extract, dried fruit, liquid extracts

An interaction check asks whether these two react with each other — it does not ask whether White Mulberry is a good idea for someone in your situation. Here is what our White Mulberry record says about it on its own.

White Mulberry: dosing

There is no officially established standard dose for white mulberry supplements. Doses used in studies have varied widely depending on the plant part and extract, and there is not enough consistent research to recommend a specific milligram amount.If you choose to use it, follow the directions on the product label and do not exceed the suggested amount.

Taking White Mulberry and Nadolol Together: Common Questions

Is it safe to take White Mulberry with Nadolol?
We do not list a known interaction between White Mulberry and Nadolol. That does not guarantee the combination is risk-free, so confirm with your pharmacist or doctor — especially if you take other medications or have a health condition.
Do White Mulberry and Nadolol have any of the same side effects?
Yes — our sources link each of them separately to 3 of the same effects. That is not an interaction: neither changes how your body handles the other. It does mean that if one of those effects turns up, it can be harder to tell which one is behind it. They are listed on this page with the source behind each.
Are White Mulberry and Nadolol used for the same thing?
They overlap in purpose, which usually means the real question is whether you need both rather than whether they are safe together. This page lists the shared uses and how strong the evidence is for White Mulberry in each. That is a conversation for your prescriber, especially if Nadolol is being adjusted to a target.
How was the White Mulberry and Nadolol combination checked?
Interactions in our licensed database are recorded against drug classes. Nadolol is filed under 5 classifications, and White Mulberry has documented interactions with 2 drug classes — none of Nadolol's classifications are among them. A medication can belong to classes beyond those recorded in our dataset, so this describes how the check was run rather than guaranteeing safety.
Does White Mulberry interact with any other medications?
Yes. White Mulberry has 87 documented drug interactions in our database — Nadolol is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
Does Nadolol interact with any supplements?
Yes. Nadolol has documented interactions with 145 supplements in our database — White Mulberry is not one of them. The Nadolol interaction page linked on this page lists every one, ranked by severity.
