Drug & supplement interaction

Broccoli Sprout + Colestipol

Colestipol brand name: Colestid.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 20, 2026
The bottom line No known interaction

We found no known interaction between Broccoli Sprout and Colestipol 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 Colestipol 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.

Broccoli Sprout and Colestipol

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 Colestipol and Broccoli Sprout 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 Colestipol

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

  • Stomach pain / Diarrhea Additional detail

    Broccoli Sprout

    “Orally, loose stools, diarrhea, abdominal pain, and abdominal cramping have been reported following intake of broccoli seed and broccoli sprout extracts, particularly at high doses. Consuming raw broccoli sprouts that have been improperly grown may cause food-borne illness. Improperly grown broccoli sprouts may be contaminated with bacteria, including Listeria monocytogenes, Salmonella, or Escherichia coli O157:H7.”

Special populations

Broccoli Sprout in Pregnancy & Breastfeeding

Pregnancy And Lactation Likely Safe

When COOKED broccoli sprouts are consumed in amounts commonly found in foods. Broccoli sprout is considered safe for dietary consumption provided the sprouts are grown in accordance with food safety recommendations developed by the US Food and Drug Administration (FDA) and are cooked prior to eating.

Pregnancy And Lactation Possibly Unsafe

When RAW broccoli sprouts are consumed in amounts commonly found in foods. There is evidence that uncooked broccoli sprouts may be contaminated with bacteria, including Listeria monocytogenes, Salmonella, or Escherichia coli O157:H7. Pregnant individuals are particularly susceptible to these food-borne illnesses, and becoming infected can increase the risk of miscarriage, stillbirth, premature birth, or neonatal infection. There is insufficient reliable information available about the safety of broccoli sprout extract during pregnancy or lactation; avoid using.

How to take them

Some Colestipol Products Have a Food Rule — Broccoli Sprout Should Not Break It

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

Patients should take other drugs at least one hour before or four hours after colestipol hydrochloride tablets to minimize possible interference with their absorption.

From the Dosage and Administration section of the FDA label we read for Colestipol — 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 Broccoli Sprout

What is Broccoli Sprout?

  • Antioxidant support
  • Detoxification support
  • General heart health
  • Anti-inflammatory support
  • Digestive and gut health

Broccoli sprouts are young broccoli seedlings rich in a compound called sulforaphane, which is being studied for antioxidant, anti-inflammatory, and detoxification effects. Early research is promising for some uses, but high-quality human evidence is still limited, so they should be viewed as a healthy food rather than a proven treatment. As food they are generally safe, but talk to your pharmacist or doctor before using concentrated supplements, especially during pregnancy or breastfeeding.

Brassica oleracea var. italica · Brassicaceae · Young sprouts (seedlings) of the broccoli plant · Fresh sprouts, powders, capsules, tablets, and standardized extracts (often labeled as containing sulforaphane or glucoraphanin)

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

Broccoli Sprout: dosing

There is no official standardized dose for broccoli sprouts or their extracts. Studies have used different forms and amounts, often described by the amount of glucoraphanin or sulforaphane, which makes comparison difficult.If you are eating them as food, a serving as part of a balanced diet is reasonable. If you choose a supplement, follow the directions on the product label and choose a reputable brand.

About Colestipol

What Is Colestipol Used For?

Brand name: Colestid

Colestipol — available as oral suspension and tablets under brands including Colestid, Flavored Colestid, and Colestipol Hydrochloride — is used as part of a broader treatment plan (including diet) to lower elevated LDL cholesterol in adults with primary hypercholesterolemia (a condition where LDL cholesterol stays high despite dietary changes).

It is not a standalone fix. Diet, weight management, and other lifestyle changes come first, and colestipol is added when those steps alone aren't enough to reach target LDL levels.

Taking Broccoli Sprout and Colestipol Together: Common Questions

Is it safe to take Broccoli Sprout with Colestipol?
We do not list a known interaction between Broccoli Sprout and Colestipol. 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 Broccoli Sprout and Colestipol 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 Broccoli Sprout and Colestipol at the same time of day?
At least one FDA label for a product containing Colestipol 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 Colestipol on its own and move Broccoli Sprout 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.
How was the Broccoli Sprout and Colestipol combination checked?
Interactions in our licensed database are recorded against drug classes. Colestipol is filed under 2 classifications, and Broccoli Sprout has documented interactions with 2 drug classes — none of Colestipol'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 Sprout interact with any other medications?
Yes. Broccoli Sprout has 187 documented drug interactions in our database — Colestipol 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 Colestipol interact with any supplements?
Yes. Colestipol has documented interactions with 18 supplements in our database — Broccoli Sprout is not one of them. The Colestipol interaction page linked on this page lists every one, ranked by severity.
