The bottom line No known interaction

We found no known interaction between Broccoli and Bevacizumab 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.

Broccoli and Bevacizumab

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 Bevacizumab and Broccoli 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.

How we checked

Why No Interaction Is Listed for Bevacizumab

Interactions in our licensed database are recorded against drug classes, not just single drug names. Bevacizumab is filed under a single classification — oral drugs. Broccoli has documented interactions with 2 drug classes — the most serious being cytochrome p450 1a2 (cyp1a2) substrates (moderate) and cytochrome p450 2a6 (cyp2a6) substrates (moderate) — and none of Bevacizumab’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

What Broccoli Itself Has Been Linked To

This is not an interaction — nothing below involves Bevacizumab. It is the side-effect record for Broccoli on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Broccoli, this list is the first place to look. One entry is worth acting on rather than waiting out — marked below.

  • An allergic reaction Worth acting on Additional detail

Everything above comes from the Natural Medicines adverse-effect record for Broccoli — expand a row for the licensed statement it rests on. We haven’t matched Bevacizumab to its FDA label in our system yet, so we can’t compare its own side-effect list here — the leaflet that comes with your prescription is the authoritative list for Bevacizumab.

Broccoli in Pregnancy & Breastfeeding

Pregnancy And Lactation Likely Safe

When used orally in food amounts. There is insufficient reliable information available about the safety of broccoli when used in medicinal amounts during pregnancy and lactation; avoid using.

Overlapping uses

What Bevacizumab Is Prescribed For, and What Broccoli Has Been Studied For

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

Bevacizumab is prescribed for: Avastin, Avzivi, and JOBEVNE are brand names for bevacizumab injection, used to treat multiple types of cancer. Avastin is indicated for metastatic colorectal cancer, non-squamous non-small cell lung cancer, recurrent glioblastoma (a type of brain tumor) in adults, metastatic renal cell carcinoma (kidney cancer), persistent or metastatic cervical cancer, epithelial ovarian, fallopian tube, or primary peritoneal cancer, and unresectable or metastatic hepatocellular carcinoma (liver cancer). These treatments are typically used in combination with chemotherapy, though in some settings bevacizumab is given as a single agent. Avastin is not indicated for adjuvant (preventive post-surgery) treatment of colon cancer.

Broccoli has been studied for:

  • Colorectal cancer Natural Medicines rates the evidence for Broccoli: Possibly Effective Read what the research shows

    Broccoli for colorectal cancer

    Consumption of cruciferous vegetables, including broccoli, seems to reduce the risk of developing colorectal cancer.

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 Bevacizumab on your own; if you are taking Broccoli for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

See Every Supplement That Interacts With Bevacizumab

This page covers Broccoli only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Bevacizumab page lists 17 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Coffee Charcoal (moderate), European Mandrake (moderate), Glucomannan (moderate) and Guar Gum (moderate).

By severity: 1 major · 7 moderate · 9 minor.

From our pharmacist’s overview on the Bevacizumab page

“Anyone receiving bevacizumab (Avastin) is fighting a serious cancer, often reaching for fiber supplements or charcoal to settle treatment-related stomach trouble, and that is exactly where this list deserves genuine attention. Every one of the 17 entries on file works through absorption, and the single major-rated interaction, activate…”

About Broccoli

What is Broccoli?

  • General nutrition and antioxidant support
  • Heart and digestive health
  • Detoxification support
  • Cancer risk reduction (popular interest)
  • Blood sugar support

Broccoli is a nutritious cruciferous vegetable rich in fiber, vitamins, and plant compounds like sulforaphane that have drawn scientific interest for health benefits. Eating broccoli as food is safe and healthy for most people, but concentrated supplements and extracts are less studied and benefits are not firmly proven. Talk to your pharmacist or doctor before using broccoli supplements, especially in high doses.

Brassica oleracea var. italica · Brassicaceae · Florets, sprouts, seeds, and stalks · Whole vegetable (fresh, frozen, cooked), broccoli sprouts, powders, capsules, and sulforaphane or glucoraphanin extracts

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

Broccoli: dosing

There is no official or standardized supplement dose for broccoli. As a food, broccoli can simply be enjoyed as part of a balanced diet.For broccoli sprout and sulforaphane products, the amount of active compound varies a lot between brands, and a proven effective dose has not been established.

Taking Broccoli and Bevacizumab Together: Common Questions

Is it safe to take Broccoli with Bevacizumab?
We do not list a known interaction between Broccoli and Bevacizumab. 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.
Are Broccoli and Bevacizumab 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 Broccoli in each. That is a conversation for your prescriber, especially if Bevacizumab is being adjusted to a target.
How was the Broccoli and Bevacizumab combination checked?
Interactions in our licensed database are recorded against drug classes. Bevacizumab is filed under 1 classification, and Broccoli has documented interactions with 2 drug classes — none of Bevacizumab'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 Broccoli interact with any other medications?
Yes. Broccoli has 187 documented drug interactions in our database — Bevacizumab 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 Bevacizumab interact with any supplements?
Yes. Bevacizumab has documented interactions with 17 supplements in our database — Broccoli is not one of them. The Bevacizumab interaction page linked on this page lists every one, ranked by severity.
