HelloPharmacist Scorecard of Constipation Formula Vanilla Flavor 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

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 0 of its 3 active ingredients.
  • “Proprietary Blend” is a proprietary blend — the label gives one combined amount (0.13 mL) without saying how much of each component you get.

This formula contains 3 active ingredients in liquid extract form: artichoke leaf glycerite, boldo glycerite, and black radish glycerite. The inactive ingredients are glycerin and vanilla flavor.

The first two are delivered as a proprietary blend, so you won't see the exact dose of each one.

Does it work?

Not established
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
Not established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use.

Why this rating?
  • The label markets this product for: Mild constipation relief.
  • We looked for evidence on: Constipation, Bowel regularity, Digestive function.
  • The closest evidence on file: Artichoke is rated "Insufficient Reliable Evidence To Rate" for Irritable bowel syndrome (IBS) (Natural Medicines).

The evidence for this formula's ingredients is mixed. Artichoke leaf extract is possibly effective for high cholesterol (hyperlipidemia) and indigestion (dyspepsia), but the evidence for fatty liver disease is insufficient to rate.

Boldo and black radish both have insufficient evidence—we don't have reliable data showing they work for the conditions they're traditionally used for, including gallbladder issues, kidney stones, joint pain, and diabetes. If you're taking this for constipation specifically, the facts we hold don't cover that claim.

The evidence, ingredient by ingredient Artichoke Boldo Radish

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 3 of the 3 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 3 of 3.
  • General safety write-ups exist for 3 of 3.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Artichoke is generally well tolerated when used short-term, though quality and dosing vary by product. The most common side effects are abdominal pain, diarrhea, bloating, hunger, and nausea.

A rare but serious risk is anaphylaxis in people sensitive to inulin; artichokes are also risky for anyone allergic to ragweed, chrysanthemums, daisies, or other plants in the Asteraceae family. Boldo is generally well tolerated in food amounts but can cause serious harm in medicinal doses.

Liver damage is the main concern—cases of elevated liver enzymes and jaundice have been reported. Common side effects are abdominal pain, nausea, and vomiting.

Black radish is safe in normal food amounts; large concentrated doses may irritate the stomach and cause indigestion. One case of allergic reaction with throat tightness and hives has been reported.

During pregnancy, boldo is unsafe (may stimulate the uterus); artichoke has not been studied enough and is best avoided; there isn't enough data on black radish. During breastfeeding, both boldo and artichoke are best avoided due to lack of safety information; black radish's safety is also not well studied.

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?
  • 3 of the 3 matched ingredients can interact with medications — Radish, Boldo, Artichoke.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; immunosuppressants / transplant drugs; diabetes medications; lithium.
  • For scale: 791 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 with your doctor or pharmacist if you take blood pressure medications (artichoke may lower your pressure further), blood thinners or antiplatelet drugs (boldo may increase bleeding risk), diabetes medications (artichoke and black radish may lower your blood sugar), lithium (boldo may raise its levels), warfarin (boldo may increase bleeding risk), tacrolimus (boldo may lower its levels), or any drugs processed by your liver, especially through the CYP2C19 or CYP2B6 pathways. Also mention if you take medications toxic to the liver.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

This product is intended for digestive support, though its effectiveness is not well established in the data we hold. If you take any medications—especially blood pressure drugs, blood thinners, diabetes medications, lithium, warfarin, tacrolimus, or drugs processed by your liver—you'll need to check your exact medications before starting.

The boldo ingredient carries real safety concerns, particularly for your liver and with certain medications. Talk with your doctor or pharmacist before adding this to your routine.

Each ingredient & the kinds of drugs it affects

For each ingredient in Constipation Formula Vanilla Flavor with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.

Boldo Glycerite Liquid Extract5 drug types · 482 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, taking boldo with anticoagulant/antiplatelet drugs might increase the risk of bleeding.
Animal and in vitro research shows that boldine, a constituent of boldo, has antiplatelet activity. In one case report, an adult taking a combination of boldo and fenugreek with warfarin experienced an increase in international normalized ratio (INR); however, it is unclear if this effect was due to boldo, fenugreek, the combination, or another factor.

Likelihood Possible Evidence D
Hepatotoxic Drugs

Theoretically, taking boldo with hepatotoxic drugs might increase the risk of hepatic injury and disease.
Boldo leaf contains ascaridole, a known liver toxin. Many cases of hepatotoxicity, including elevated liver transaminase levels and jaundice, have been reported in patients taking boldo.

Likelihood Possible Evidence D
Lithium

Theoretically, taking boldo with lithium might increase the levels and clinical effects of lithium.
Boldo is believed to have diuretic effects. Theoretically, these diuretic effects might reduce the excretion of lithium. The dose of lithium might need to be decreased.

Likelihood Probable Evidence D
Tacrolimus (Prograf)

Taking boldo with tacrolimus may decrease the levels and clinical effects of tacrolimus, potentially increasing the risk of transplant rejection.
In one case report, a patient with a long-term history of stable tacrolimus levels developed subtherapeutic levels after taking boldo 300 mg twice daily orally for several weeks. Tacrolimus levels returned to normal after discontinuing boldo. However, the mechanism of this interaction is unclear.

Likelihood Possible Evidence D
Warfarin (Coumadin)

A combination of boldo and fenugreek was thought to be associated with an increased international normalized ratio (INR) in a female on warfarin. It is not clear if boldo, fenugreek, or the combination played a role in this interaction. Therefore, boldo may have additive effects with warfarin.

Likelihood Possible Evidence D

Artichoke Leaf Glycerite Liquid Extract4 drug types · 363 drugs

Antidiabetes Drugs

Theoretically, artichoke leaf extract may increase the risk of hypoglycemia when taken with antidiabetes drugs.
A meta-analysis of small clinical studies shows that taking artichoke leaf extract for 8-12 weeks can modestly reduce fasting plasma glucose when compared with placebo.

Likelihood Possible Evidence D
Antihypertensive Drugs

Theoretically, artichoke leaf extract may increase the risk of hypotension when taken with antihypertensive drugs.
A meta-analysis of small clinical studies in patients with hypertension shows that taking artichoke can reduce systolic blood pressure by around 3 mmHg and diastolic blood pressure by around 2 mmHg when compared with placebo.

Likelihood Possible Evidence D
Cytochrome P450 2B6 (Cyp2B6) Substrates

Theoretically, artichoke might increase serum levels of drugs metabolized by CYP2B6.
In vitro research shows that artichoke leaf extract inhibits CYP2B6 activity. However, this interaction has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 2C19 (Cyp2C19) Substrates

Theoretically, artichoke might increase serum levels of drugs metabolized by CYP2C19.
In vitro research shows that artichoke leaf extract inhibits CYP2C19 activity. However, this interaction has not been reported in humans.

Likelihood Possible Evidence D

Black Radish Glycerite Liquid Extract1 drug type · 86 drugs

Antidiabetes Drugs

Theoretically, radish might increase the risk of hypoglycemia when taken with antidiabetes drugs.
Animal research shows that radish extract, juice, and sprouts can reduce glucose levels. Animal research also shows that radish root juice 300 mg/kg reduces fasting and postprandial blood glucose in a rat model of diabetes, with effects similar to glibenclamide.

Constipation Formula Vanilla Flavor by TerraVita: Common Questions

Does Constipation Formula Vanilla Flavor by TerraVita interact with any medications?
Yes. Based on its ingredients, Constipation Formula Vanilla Flavor has a known interaction with 790 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Constipation Formula Vanilla Flavor contains 3 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is 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.
Can I take this while pregnant?
No—boldo is unsafe in pregnancy because it may stimulate the uterus. Artichoke hasn't been studied enough in pregnancy and is best avoided. Black radish safety during pregnancy isn't well established either. Talk with your doctor or pharmacist before using this product if you're pregnant or planning to become pregnant.
Can I take this while breastfeeding?
Both boldo and artichoke are best avoided while breastfeeding because there isn't enough safety information. Black radish's safety during breastfeeding is also not well studied. Speak with your doctor or pharmacist if you're breastfeeding and considering this product.
What are the most common side effects?
Abdominal pain, diarrhea, bloating, nausea, and vomiting are the most common side effects reported. These are mild and usually go away, but if they're severe or persistent, stop taking it and talk with your pharmacist or doctor.
Could I have an allergic reaction to this?
Yes—artichoke can trigger allergic reactions in people sensitive to ragweed, chrysanthemums, daisies, or other plants in the same family. Anaphylaxis to artichoke has been reported rarely. Black radish has caused throat tightness and hives in one reported case. If you have plant allergies or notice throat tightness, swelling, or difficulty breathing, seek emergency help right away.
Is boldo safe to take long-term?
No—boldo may be used short-term in low doses, but it contains ascaridole, a liver toxin, and cases of liver damage have been reported in people taking it. It's not meant for long-term use. If you're taking this product for more than a few weeks, check with your doctor or pharmacist.
How is this different from a fiber supplement?
The facts we hold don't cover how this product compares to fiber supplements or whether it actually works for constipation. We have effectiveness data for some ingredients' traditional uses (like artichoke for high cholesterol and indigestion), but not for constipation itself. Ask your pharmacist which option might be right for you.
