HelloPharmacist Scorecard of Carob by Hawaii Pharm

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

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Jul 16, 2026

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.

This product contains one active ingredient: carob pod and seed extract in dried form. Carob is a legume pod commonly used as a food ingredient and thickener.

The liquid also contains alcohol, water, and glycerin as inactive ingredients to preserve and deliver the extract.

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 Carob's overall clinical evidence instead.

Moderate

Some clinical evidence supports Carob 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: Diarrhea — rated "Possibly Effective" (Natural Medicines).

Carob is possibly effective for diarrhea based on the evidence we hold. For athletic performance, diabetes management, and familial hypercholesterolemia (a cholesterol condition), the evidence isn't established — we don't have reliable data to rate how well it works for those uses.

The evidence, ingredient by ingredient Carob

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.

Carob is generally well tolerated in normal food amounts, since it's widely eaten as a food ingredient. However, concentrated supplement doses haven't been well studied, so use caution if you're taking medicinal amounts rather than food amounts.

The product contains alcohol, which you should note if you're sensitive to it or avoiding alcohol. Rare cases of allergic reactions (rash, vomiting) and serious intestinal complications have been reported in infants, particularly those with food allergies or existing digestive conditions — this product should not be given to infants without guidance from their pediatrician.

Pregnancy and lactation safety data isn't on file; talk with your doctor or pharmacist before using it if you're pregnant or breastfeeding.

Side effects, ingredient by ingredient Carob

Meds to double-check

Minor interactions only
Known Interaction Concern · database check
Minor only

Only Minor-severity interactions are documented for these ingredients.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Carob.
  • The most serious interaction on file is rated Minor.
  • For scale: 2,023 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 taking this product, check all your oral medications — carob may interfere with their absorption. Use the medication checker below to see if any of your drugs are affected.

The effect is minor, but timing your doses 30–60 minutes apart helps.

The bottom line

Scorecard at a glanceFully disclosed formula with some supporting evidence behind its ingredients' uses. Only minor medication interactions are documented, and safety information is well characterized.

Carob may help with occasional diarrhea and is a food ingredient most people eat without trouble. The main caution is that it might reduce how well oral medications are absorbed, so timing matters — take it 30–60 minutes after your drugs.

Check your medications with the tool on this page before starting, and talk it over with your doctor or pharmacist if you're pregnant, breastfeeding, or have a history of food allergies.

Carob by Hawaii Pharm: Common Questions

Does Carob by Hawaii Pharm interact with any medications?
Yes. Based on its ingredients, Carob has a known interaction with 2,022 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Carob 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.
Does carob really help with diarrhea?
Carob is possibly effective for diarrhea based on available evidence. It's been used traditionally for this, but the research isn't conclusive — results vary. If you're dealing with ongoing diarrhea, talk with your doctor to rule out other causes.
This product contains alcohol — how much?
The product facts don't specify the exact alcohol percentage. If you're avoiding alcohol, pregnant, breastfeeding, or taking medications that don't mix with alcohol, check the label or contact the manufacturer for the exact amount.
Is carob safe to give to children?
Carob is safe in normal food amounts. However, rare serious reactions have been reported in infants, especially those with food allergies or digestive disorders like FPIES. Don't give this supplement to infants without talking to their pediatrician first.
Can I take this while pregnant or breastfeeding?
Safety data for pregnancy and breastfeeding isn't on file for this ingredient. Talk with your doctor or pharmacist for personalized advice before taking it during pregnancy or while breastfeeding.
Why do I need to wait 30–60 minutes after my medications to take carob?
Carob may reduce how well your body absorbs oral drugs. Taking it separately — at least 30–60 minutes after your medication — helps your drug work as intended.
