Drug & supplement interaction

White Mulberry + Obinutuzumab

Obinutuzumab brand name: Gazyva.

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 Obinutuzumab 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 label for Obinutuzumab states a food rule worth keeping to, and 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.

Interaction report

White Mulberry and Obinutuzumab

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 Obinutuzumab 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.

What to actually watch for

No Interaction Found — But Data Suggests White Mulberry and Obinutuzumab 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.

  • Constipation / Diarrhea 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.”

    Obinutuzumab

    Listed in the ADVERSE REACTIONS section of the FDA label for Obinutuzumab. Read the label on DailyMed ›

Reported for White Mulberry but not commonly for Obinutuzumab: bloating or gas.

Effects for Obinutuzumab come from the ADVERSE REACTIONS section of its FDA label; effects for White Mulberry come from the Natural Medicines adverse-effect record, quoted above. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

How to take them

Some Obinutuzumab Products Have a Food Rule — White Mulberry Should Not Break It

At least one FDA label for a product containing Obinutuzumab says to take it on an empty stomach. Most supplements — White Mulberry included — are taken with a meal, so the easy mistake is swallowing both together at breakfast. Where that rule applies, keep Obinutuzumab on its own and move White Mulberry to a meal later in the day.

This may not be true of your version. Food instructions belong to the product, not the ingredient: two Obinutuzumab products can carry different directions, and extended-release forms often differ from immediate-release ones. The label we read is quoted below — check the directions on your own box or bottle, or ask your pharmacist, for how to take the exact product you were given.

650–1,000 mg acetaminophen At least 30 minutes before GAZYVA infusion.

From the Dosage and Administration section of the FDA label we read for Obinutuzumab — where that label names a specific product, the instruction is that product's. Read the label on DailyMed ›

A food rule is not an interaction — it is about how much of the medicine you absorb. The directions that came with your own product, and your pharmacist, outrank anything on this page.

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.

About Obinutuzumab Injection

What Is Obinutuzumab Injection Used For?

Brand name: Gazyva

Gazyva is used to treat three conditions. For chronic lymphocytic leukemia (CLL), it is given in combination with chlorambucil in patients who have not been treated before. For follicular lymphoma (FL), it is used either with bendamustine (for patients whose disease came back or stopped responding to a rituximab-based regimen) or with chemotherapy (for previously untreated advanced disease) — in both cases followed by Gazyva alone as maintenance therapy.

Gazyva is also approved for active lupus nephritis — a type of kidney inflammation caused by lupus — in adults who are already receiving standard therapy for the condition.

Taking White Mulberry and Obinutuzumab Together: Common Questions

Is it safe to take White Mulberry with Obinutuzumab?
We do not list a known interaction between White Mulberry and Obinutuzumab. 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 Obinutuzumab have any of the same side effects?
Yes — our sources link each of them separately to 2 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.
Should I take White Mulberry and Obinutuzumab at the same time of day?
At least one FDA label for a product containing Obinutuzumab says to take it on an empty stomach, and supplements are usually taken with a meal — so taking them together at breakfast is the easy mistake. Where that applies, keep Obinutuzumab on its own and move White Mulberry to a meal later in the day. Food instructions belong to the product rather than the ingredient, so check the directions on your own box. This is about absorption, not an interaction.
Does White Mulberry interact with any other medications?
Yes. White Mulberry has 87 documented drug interactions in our database — Obinutuzumab is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
