HelloPharmacist Scorecard of St. John's Bread by TerraVita

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.

This product contains one active ingredient: St. John's Bread Bean Pod Glycerite Liquid Extract, which is carob.

Carob is a legume pod often used as a natural thickener and chocolate-like flavoring. The liquid also contains glycerin and strawberry flavor as inactive ingredients to make it easier to take.

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
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: digestive health and gastrointestinal comfort.
  • We looked for evidence on: Diarrhea, Dyspepsia, Nausea and vomiting, acid reflux, digestive upset.
  • The strongest evidence on file: Carob is rated "Possibly Effective" for Diarrhea (Natural Medicines).
  • Also on file: Carob is rated "Insufficient Reliable Evidence To Rate" for Dyspepsia, Nausea and vomiting.

Carob has possibly effective evidence for helping with diarrhea. For athletic performance, diabetes, and familial hypercholesterolemia (a genetic cholesterol condition), the evidence isn't established enough for us to rate it either way.

If you're thinking about using this product for diarrhea, talk with your pharmacist or doctor about whether it's right for your situation.

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 widely eaten as a food and is generally considered safe in normal food amounts. However, concentrated supplement doses like those in this liquid haven't been well studied, so use caution with higher-than-food amounts.

In infants, carob-thickened formula has been linked to serious digestive problems, including vomiting and necrotizing enterocolitis (a life-threatening gut inflammation) in premature babies — this product is not appropriate for infants. If you're pregnant or breastfeeding, there isn't enough safety data on file for this product to know either way; talk with your doctor or pharmacist for personalized advice.

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.

Oral medications (drugs you swallow) are the main concern here — carob may reduce how well your body absorbs them. The interaction is Minor, but timing matters: take your pills 30–60 minutes away from this product.

Laboratory research shows that carob, when consumed as part of the diet or used as a thickening agent in infant formula, reduces the absorption of certain minerals. Take carob 30-60 minutes after oral medications.
