HelloPharmacist Scorecard of Red Cabbage Powder by TerraVita Premium Collection

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

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.
  • No proprietary blends here — you can verify the dose of every single component.

Red Cabbage Powder by TerraVita Premium Collection contains one active ingredient: red cabbage powder. There are no other inactive ingredients listed.

As a powder, you're getting a concentrated form of whole red cabbage — the same vegetable you'd buy at a grocery store, but dried and ground into a fine texture.

Does it work?

Moderate evidence
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

This product doesn't appear to be marketed for a specific use, so we graded Cabbage's overall clinical evidence instead.

Moderate

Some clinical evidence supports Cabbage for:

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.
  • Since the label doesn't commit to one use, we graded the ingredient's overall clinical evidence instead.
  • On file: Breast engorgement — rated "Possibly Effective" (Natural Medicines).

Red cabbage powder is possibly effective for breast engorgement, based on the evidence we hold. For other potential uses — including bladder cancer, lung cancer, colorectal cancer, gastric cancer, and high cholesterol — we don't have reliable evidence to rate whether it works.

Most of what we know comes from eating cabbage as food, not taking a supplement powder.

The evidence, ingredient by ingredient Cabbage

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.

Cabbage is generally well tolerated as a food. However, concentrated supplement powders or large medicinal doses haven't been thoroughly studied, so we know less about safety at higher amounts.

Rarely, people allergic to broccoli, cauliflower, or other vegetables in the cabbage family (Brassicaceae) may also react to cabbage — reactions range from contact skin irritation to, in very rare cases, severe allergic reactions. For pregnancy, we don't have enough data to know either way — talk with your doctor or pharmacist about whether this supplement is right for you during pregnancy.

Side effects, ingredient by ingredient Cabbage

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 — Cabbage.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications.
  • For scale: 325 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 red cabbage powder, double-check with your doctor or pharmacist if you take blood thinners like warfarin, diabetes medications, acetaminophen or other over-the-counter pain relievers, anti-anxiety drugs like oxazepam, or any drug that's processed through CYP1A2 enzymes or glucuronide conjugation in your liver. Cabbage can reduce how well these medications work.

The bottom line

Scorecard at a glanceFully disclosed formula with some supporting evidence behind its ingredients' uses. Moderate medication interactions have been identified, and safety information is well characterized.

Red cabbage powder may interest you if you're exploring natural ways to support breast health or if you simply want the nutrients from cabbage in a concentrated form. If you take blood thinners, diabetes medications, pain relievers, anti-anxiety drugs, or any other regular medication, check with your doctor or pharmacist before starting this product — the powder is potent enough to interfere with how those drugs work.

Red Cabbage powder6 drug types · 325 drugs

Acetaminophen (Tylenol, Others)

Cabbage might increase clearance and reduce the effects of acetaminophen.
A small clinical study shows that daily consumption of cabbage and Brussels sprout decreases acetaminophen levels by as much as 16%, with some evidence suggesting that this effect is due to increased elimination through glucuronide conjugation.

Likelihood Probable Evidence B
Antidiabetes Drugs

Theoretically, cabbage might increase the risk of hypoglycemia when taken with antidiabetes drugs.
Animal and in vivo research suggests that cabbage might have hypoglycemic effects.

Likelihood Possible Evidence D
Cytochrome P450 1A2 (Cyp1A2) Substrates

Theoretically, cabbage might decrease levels of drugs metabolized by CYP1A2.
Some animal research suggests that cabbage or its constituent indole-3-carbinol might increase drug metabolism and elimination by stimulating CYP1A2 activity.

Likelihood Possible Evidence D
Glucuronidated Drugs

Theoretically, cabbage might increase clearance and decrease the effects of drugs metabolized through glucuronide conjugation.
A small clinical study shows that daily consumption of cabbage and Brussels sprout decreases levels of some drugs metabolized through glucuronide conjugation.

Likelihood Probable Evidence B
Oxazepam (Serax)

Cabbage might increase clearance and reduce the effects of oxazepam.
A small clinical study shows that daily consumption of cabbage and brussels sprout decreases oxazepam levels by as much as 17%, with some evidence suggesting that this effect is due to increased elimination through glucuronide conjugation.

Likelihood Probable Evidence B
Warfarin (Coumadin)

Theoretically, cabbage might decrease the anticoagulant effects of warfarin.
Cabbage contains vitamin K. If consumed in large quantities, cabbage might decrease the anticoagulant effects of warfarin.

Red Cabbage Powder by TerraVita Premium Collection: Common Questions

Does Red Cabbage Powder by TerraVita Premium Collection interact with any medications?
Yes. Based on its ingredients, Red Cabbage Powder has a known interaction with 325 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Red Cabbage Powder 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.
Will red cabbage powder actually reduce my blood sugar?
Animal and lab studies suggest cabbage might lower blood sugar, but we don't have solid human trial data. That's why it can be risky with diabetes medications — the combined effect could drop your blood sugar too low. Never use it to replace your prescribed diabetes drug; talk to your doctor if you're interested in adding it.
Is this safe for my breast engorgement?
Red cabbage is possibly effective for breast engorgement based on the evidence we hold. Traditionally, chilled cabbage leaves are applied directly to the breast. However, the safety data we have is limited, so talk with your doctor or midwife first before you try it.
Can I take this if I'm on Tylenol or ibuprofen?
You can take acetaminophen (Tylenol), but red cabbage powder may reduce its effectiveness by up to 16% by speeding how your body clears it. Ibuprofen is not listed in our data, so we can't say whether this powder affects it. Check with your pharmacist about your specific pain reliever.
I'm allergic to broccoli. Can I take this?
You should be cautious. Broccoli, cabbage, and cauliflower are all in the same plant family, and the proteins that trigger allergies are similar across them. If you've had an allergic reaction to broccoli, talk with your doctor or allergist before trying this cabbage powder.
What happens if I take this with warfarin?
Cabbage is high in vitamin K, which can work against warfarin's blood-thinning effects. Large amounts of cabbage powder could weaken your clot protection. Do not start this supplement if you take warfarin without checking with your doctor first.
Does red cabbage powder have any fillers or other ingredients?
No — this product is just red cabbage powder with no inactive ingredients added.
