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 12 active ingredients.
  • “Proprietary Herbal Blend” is a proprietary blend — the label gives one combined amount (550 mg) without saying how much of each component you get.
  • “Enzymes” is listed as a grouped ingredient — the label doesn't break down how much of each component you get.

HealthForce's Intestinal Movement Formula contains 12 ingredients, of which several are digestive enzymes: amylase, protease, lipase, and cellulase help break down food. The product also includes rhubarb root (a traditional laxative), peppermint and ginger (for digestive comfort), oregano and thyme (herbs with antimicrobial properties), wasabi extract, and whole leaf aloe ferox (another laxative agent).

The final two ingredients—a proprietary herbal blend and an "Enzymes" blend—are groupings of other components already listed individually. Inactive ingredients are not present in this formula.

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: intensive or gentle intestinal cleanse.
  • We looked for evidence on: Constipation, Abdominal pain, Dyspepsia, Diarrhea, bowel regularity, digestive transit — and 1 related terms.
  • The strongest evidence on file: Aloe is rated "Possibly Effective" for Constipation (Natural Medicines).
  • Also on file: Peppermint is rated "Possibly Effective" for Dyspepsia.
  • Also on file: Lipase is rated "Insufficient Reliable Evidence To Rate" for Dyspepsia.

Evidence for this product's active ingredients is mixed. Peppermint is likely effective for irritable bowel syndrome (IBS) and possibly effective for indigestion and nausea.

Ginger is possibly effective for pregnancy-related nausea, menstrual cramps, and osteoarthritis, though it shows no benefit for exercise-induced muscle soreness. Aloe is possibly effective for constipation, acne, psoriasis, and blood sugar control.

Rhubarb is possibly effective for pancreatitis and menopausal symptoms. For the others—protease, lipase, oregano, thyme, wasabi extract, and nopal cactus—we lack sufficient evidence to rate their effectiveness for any condition.

The evidence we hold does not establish this formula's effectiveness for intestinal movement specifically.

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 10 of the 10 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 10 of 10.
  • General safety write-ups exist for 10 of 10.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Most ingredients are generally well tolerated in typical amounts. Peppermint and ginger are likely or possibly safe in pregnancy; thyme is likely safe.

However, rhubarb, oregano, and aloe ferox are possibly unsafe in pregnancy—rhubarb and aloe may stimulate the uterus and act as strong laxatives. Aloe ferox is also possibly unsafe while breastfeeding.

Rhubarb and oregano are not recommended while nursing due to laxative compounds or insufficient data. Peppermint and ginger are likely safe during breastfeeding, but concentrated supplements should be checked with your provider first.

Common mild side effects include abdominal cramping, diarrhea, nausea, and heartburn (mainly from rhubarb, peppermint, and ginger). Protease may rarely cause allergic reactions.

Aloe latex with long-term use can lead to electrolyte loss and potassium depletion. Rhubarb overuse carries similar risks.

Wasabi extract in one small study showed rare cases of protein in urine and elevated liver enzymes.

Major interaction found
Known Interaction Concern · database check
Major identified

At least one ingredient has a documented Major-severity interaction. Check your medications for a personalized result.

Why this rating?
  • 8 of the 10 matched ingredients can interact with medications — Rhubarb, Aloe, Oregano, Peppermint, Thyme, among others.
  • The most serious interaction on file is rated Major.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; immunosuppressants / transplant drugs; diabetes medications; heart-rhythm medications.
  • For scale: 1,443 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 formula, double-check with your doctor or pharmacist if you take blood thinners (warfarin and similar drugs) or antiplatelet medications (aspirin, clopidogrel, and similar agents)—rhubarb, ginger, aloe, oregano, thyme, and wasabi all carry bleeding risk. Also verify if you take digoxin or other heart glycosides (Major risk from aloe), diabetes medications (ginger, oregano, aloe, and nopal cactus may lower blood sugar), diuretics or corticosteroids (potassium loss risk from rhubarb and aloe), liver or kidney-affecting drugs (rhubarb poses Moderate concern), cyclosporine (both rhubarb and peppermint may raise levels), or medications broken down by the liver's CYP enzymes (peppermint and ginger may increase their levels).

No interactions are documented for amylase or cellulase.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with some supporting evidence for its stated purpose. Major medication interactions have been identified, and safety information is well characterized.

If you're looking for digestive support and have no heart, blood-clotting, kidney, or blood-sugar conditions, and you're not pregnant or nursing, this formula may be worth considering—especially its peppermint and ginger for comfort. However, the product combines multiple laxatives (rhubarb and aloe), so it's not for everyday use and shouldn't be taken long-term without guidance.

Before you start, check your medications with the interaction tool below, especially if you take blood thinners, heart drugs, diabetes medications, or blood-pressure drugs. Talk with your doctor or pharmacist about whether this product fits your health needs.

Ginger14 drug types · 1,007 drugs

Anticoagulant/Antiplatelet Drugs

Ginger may have antiplatelet effects and may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs. However, research is conflicting.
Laboratory research suggests that ginger inhibits thromboxane synthetase and decreases platelet aggregation. However, this has not been demonstrated unequivocally in humans, with mixed results from clinical trials. Theoretically, excessive amounts of ginger might increase the risk of bleeding when used with anticoagulant/antiplatelet drugs.

Likelihood Possible Evidence B
Antidiabetes Drugs

Theoretically, taking ginger with antidiabetes drugs might increase the risk of hypoglycemia.
Animal and human research suggests that ginger might increase insulin levels and/or decrease blood glucose levels.

Likelihood Possible Evidence D
Cytochrome P450 3A4 (Cyp3A4) Substrates

Ginger might increase or decrease the levels of CYP3A4 substrates.
In vitro research and some case reports suggest that ginger inhibits CYP3A4 activity. Three case reports from the World Health Organization (WHO) adverse drug reaction database describe increased toxicity in patients taking ginger and cancer medications that are CYP3A4 substrates (imatinib, dabrafenib, and crizotinib). However, the causality of this interaction is unclear due to the presence of multiple interacting drugs and routes of administration.
Conversely, other in vitro research suggests that ginger induces CYP3A4 activity, leading to reduced levels of CYP3A4 substrates. However, this interaction has not been reported in humans.

Likelihood Possible Evidence D
Losartan (Cozaar)

Theoretically, ginger might increase levels of losartan and the risk of hypotension.
In animal research, ginger increased the levels and hypotensive effects of a single dose of losartan. It is not clear if ginger alters the concentration or effects of losartan when taken continuously. Additionally, this interaction has not been shown in humans.

Likelihood Possible Evidence D
Nifedipine (Procardia)

Ginger may have antiplatelet effects and increase the risk of bleeding if used with nifedipine.
Clinical research shows that combined treatment with ginger 1 gram plus nifedipine 10 mg significantly inhibits platelet aggregation when compared to nifedipine or ginger alone.

Likelihood Possible Evidence B
P-Glycoprotein Substrates

Ginger might increase the absorption and blood levels of P-glycoprotein (P-gp) substrates.
In vitro research and case reports suggest that ginger inhibits drug efflux by P-gp, potentially increasing absorption and serum levels of P-gp substrates. Two case reports from the World Health Organization (WHO) adverse drug reaction database describe increased toxicity in patients taking ginger and cancer medications that are P-gp substrates (trametinib, crizotinib). However, the causality of this interaction is unclear due to the presence of multiple interacting drugs and routes of administration.

Likelihood Possible Evidence D
Phenprocoumon (Marcoumar, Others)

Ginger might increase the risk of bleeding with phenprocoumon.
Phenprocoumon, a warfarin-related anticoagulant, might increase the international normalized ratio (INR) when taken with ginger. There is one case report of a 76-year-old woman with a stable INR on phenprocoumon that increased to greater than 10 when she began consuming dried ginger and ginger tea.

Likelihood Possible Evidence D
Warfarin (Coumadin)

Ginger might increase the risk of bleeding with warfarin.
Laboratory research suggests that ginger might inhibit thromboxane synthetase and decrease platelet aggregation. In one case report, ginger increased the INR when taken with phenprocoumon, which has similar pharmacological effects as warfarin. In another case report, ginger increased the INR when taken with a combination of warfarin, hydrochlorothiazide, and acetaminophen. A longitudinal analysis suggests that taking ginger increases the risk of bleeding in patients taking warfarin for at least 4 months. However, research in healthy people suggests that ginger has no effect on INR, or the pharmacokinetics or pharmacodynamics of warfarin. Until more is known, monitor INRs closely in patients taking large amounts of ginger.

Likelihood Possible Evidence B
Calcium Channel Blockers

Theoretically, taking ginger with calcium channel blockers might increase the risk of hypotension.
Some animal and in vitro research suggests that ginger has hypotensive and calcium channel-blocking effects. Another animal study shows that concomitant administration of ginger and the calcium channel blocker amlodipine leads to greater reductions in blood pressure when compared with amlodipine alone.

Likelihood Unlikely Evidence D
Cyclosporine (Neoral, Sandimmune)

Theoretically, when taken prior to cyclosporine, ginger might decrease cyclosporine levels.
In an animal model, ginger juice taken 2 hours prior to cyclosporine administration reduced the maximum concentration and area under the curve of cyclosporine by 51% and 40%, respectively. This effect was not observed when ginger juice and cyclosporine were administered at the same time.

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

Theoretically, ginger might increase the levels of CYP1A2 substrates.
In vitro research shows that ginger inhibits CYP1A2 activity. However, this interaction has not been reported in humans.

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

Theoretically, ginger might increase the levels of CYP2B6 substrates.
In vitro research shows that ginger inhibits CYP2B6 activity. However, this interaction has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 2C9 (Cyp2C9) Substrates

Theoretically, ginger might increase the levels of CYP2C9 substrates.
In vitro research shows that ginger inhibits CYP2C9 activity. However, this interaction has not been reported in humans.

Likelihood Possible Evidence D
Metronidazole (Flagyl)

Theoretically, ginger might increase levels of metronidazole.
In an animal model, ginger increased the absorption and plasma half-life of metronidazole. In addition, the elimination rate and clearance of metronidazole was significantly reduced.

Likelihood Possible Evidence D
Ginger full monograph & interactions

Peppermint5 drug types · 796 drugs

Cyclosporine (Neoral, Sandimmune)

Theoretically, peppermint oil might increase the levels and adverse effects of cyclosporine.
In animal research, peppermint oil inhibits cyclosporine metabolism and increases cyclosporine levels. Inhibition of cytochrome P450 3A4 (CYP3A4) may be partially responsible for this interaction. An interaction between peppermint oil and cyclosporine has not been reported in humans.

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

Theoretically, peppermint might increase the levels of CYP2C19 substrates.
In vitro research shows that peppermint oil inhibits CYP2C19. So far, this interaction has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 2C9 (Cyp2C9) Substrates

Theoretically, peppermint might increase the levels of CYP2C9 substrates.
In vitro research shows that peppermint oil inhibits CYP2C9. So far, this interaction has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, peppermint might increase the levels of CYP3A4 substrates.
Clinical research in healthy volunteers shows that a single dose of peppermint oil 600 mg inhibits CYP3A4 enzymes and increases the AUC of felodipine, a CYP3A4 substrate. However, in vitro research suggests that peppermint oil only inhibits CYP3A4 at very high concentrations.

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

Theoretically, peppermint might increase the levels of CYP1A2 substrates.
In vitro and animal research shows that peppermint oil and peppermint leaf inhibit CYP1A2. However, in clinical research, peppermint tea did not significantly affect the metabolism of caffeine, a CYP1A2 substrate. It is possible that the 6-day duration of treatment may have been too short to identify a difference.

Likelihood Possible Evidence B
Peppermint full monograph & interactions

Rhubarb8 drug types · 658 drugs

Corticosteroids

Theoretically, frequent and high doses of rhubarb might increase the risk of hypokalemia when taken with corticosteroids.
Rhubarb has stimulant laxative effects. Overuse of rhubarb might compound corticosteroid-induced potassium loss.

Likelihood Possible Evidence D
Cyclosporine (Neoral, Sandimmune)

Theoretically, taking rhubarb with cyclosporine might reduce cyclosporine levels.
Animal research shows that co-administration of rhubarb decoction 0.25 or 1 gram/kg with cyclosporine 2.5 mg/kg, decreases cyclosporine maximum plasma concentration and overall exposure levels when compared with taking cyclosporine alone. The authors theorize that rhubarb might reduce cyclosporine bioavailability by inducing of P-glycoprotein and/or cytochrome P450 3A4. However, since rhubarb was administered as a single oral dose and enzyme induction usually occurs after multiple doses, it is possible that cyclosporine absorption was actually reduced via rhubarb's stimulant laxative effects. Also, the composition of the rhubarb decoction was not described.

Likelihood Possible Evidence D
Digoxin (Lanoxin)

Theoretically, overuse of rhubarb might increase the risk of adverse effects when taken with digoxin.
Rhubarb has stimulant laxative effects. Overuse of rhubarb might cause potassium depletion, increasing the risk of digoxin toxicity.

Likelihood Possible Evidence D
Diuretic Drugs

Theoretically, frequent and high doses of rhubarb might increase the risk of hypokalemia.
Rhubarb has stimulant laxative effects. Overuse of rhubarb might cause potassium depletion and compound diuretic-induced potassium loss.

Likelihood Possible Evidence D
Hepatotoxic Drugs

Theoretically, concomitant use of rhubarb with potentially hepatotoxic drugs might increase the risk of developing liver damage.
Some animal research suggests that anthraquinones in rhubarb might have hepatotoxic effects. Also, rhubarb use has been linked to at least 24 cases of liver injury, although details on the dose of rhubarb and duration of use in these cases is unclear.

Likelihood Possible Evidence D
Nephrotoxic Drugs

Theoretically, long-term use of anthraquinones from rhubarb might increase the risk of nephrotoxicity when used with nephrotoxic drugs.
The anthraquinone constituents of rhubarb have been shown to induce nephrotoxicity in animal research. Additionally, in a case report, a 23-year old female presented with kidney failure after taking 6 tablets of a proprietary slimming agent (found to contain the anthraquinones emodin and aloe-emodin from rhubarb) daily for 6 weeks and then adding diclofenac 25 mg 4 times daily for 2 days. The authors postulate that the anthraquinone constituents of rhubarb contributed to the renal dysfunction, and the addition of diclofenac, a nephrotoxic drug, led to renal failure. Until more is known, advise patients to avoid taking rhubarb if they are taking other potentially nephrotoxic drugs.

Likelihood Possible Evidence D
Stimulant Laxatives

Theoretically, rhubarb might increase the risk for fluid and electrolyte loss when taken with other stimulant laxatives.
Rhubarb has stimulant laxative effects. Concomitant use with stimulant laxatives might compound fluid and electrolyte loss.

Likelihood Possible Evidence D
Warfarin (Coumadin)

Theoretically, excessive use of rhubarb might increase the risk of bleeding when taken with warfarin.
Rhubarb has stimulant laxative effects and can cause diarrhea. Diarrhea can increase the effects of warfarin, increase international normalized ratio (INR), and increase the risk of bleeding. Advise patients who take warfarin not to take excessive amounts of rhubarb.

Likelihood Possible Evidence D
Rhubarb full monograph & interactions

whole leaf Aloe ferox7 drug types · 461 drugs

Digoxin (Lanoxin)

Theoretically, aloe latex might increase the risk of adverse effects when taken with cardiac glycosides.
Overuse of aloe latex can increase the risk of adverse effects from cardiac glycoside drugs, such as digoxin, due to potassium depletion. Overuse of aloe, along with cardiac glycoside drugs, can increase the risk of toxicity.

Likelihood Probable Evidence D
Anticoagulant/Antiplatelet Drugs

Theoretically, aloe gel might increase the risk of bleeding when taken with anticoagulant or antiplatelet drugs.
In vitro research shows that aloe gel can inhibit platelet aggregation. This inhibition was greater than that seen with celecoxib, but less than that seen with aspirin.

Likelihood Possible Evidence D
Antidiabetes Drugs

Aloe might increase the risk of hypoglycemia when taken with antidiabetes drugs.
Preliminary clinical research suggests aloe gel might lower blood glucose levels and have additive effects when used with antidiabetes drugs. Monitor blood glucose levels closely.

Likelihood Possible Evidence D
Diuretic Drugs

Theoretically, aloe latex might increase the risk of hypokalemia when taken with diuretic drugs.
Overuse of aloe latex might compound diuretic-induced potassium loss, increasing the risk of hypokalemia.

Likelihood Possible Evidence D
Stimulant Laxatives

Theoretically, aloe latex might increase the risk for fluid and electrolyte loss when taken with stimulant laxatives.
Due to cathartic laxative effects of aloe latex, concomitant use with other stimulant laxatives might compound fluid and electrolyte loss.

Likelihood Possible Evidence D
Warfarin (Coumadin)

Theoretically, aloe latex might increase the risk of bleeding when taken with warfarin.
Aloe latex has stimulant laxative effects. In some people aloe latex can cause diarrhea. Diarrhea can increase the effects of warfarin, increase international normalized ratio (INR), and increase the risk of bleeding. Advise patients who take warfarin not to take excessive amounts of aloe vera.

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

Theoretically, aloe might decrease the levels and clinical effects of CYP1A2 substrates.
In vitro research shows that aloe extract induces CYP1A2 enzymes.

Intestinal Movement Formula by HealthForce: Common Questions

Does Intestinal Movement Formula by HealthForce interact with any medications?
Yes. Based on its ingredients, Intestinal Movement Formula has a known interaction with 1,442 medications, including 1 rated major. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Intestinal Movement Formula contains 9 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.
Is this safe to take while I'm pregnant?
Several ingredients—rhubarb, oregano, and aloe ferox—are possibly unsafe in pregnancy because they may stimulate the uterus and act as strong laxatives. Peppermint, ginger, and thyme are likely or possibly safe in pregnancy, but supplement doses haven't been fully studied. Talk with your doctor or pharmacist before taking this formula during pregnancy.
Can I take this while breastfeeding?
Peppermint and ginger are likely safe while nursing, but concentrated supplements should be cleared with your provider first. Rhubarb, aloe ferox, and oregano are not recommended because laxative compounds may pass into breast milk and safety data is limited. Check with your doctor or pharmacist.
What does peppermint do in this formula?
Peppermint is likely effective for irritable bowel syndrome and possibly effective for indigestion and nausea. It helps relax the digestive tract and may ease cramping and discomfort.
Why are there so many different enzymes in here?
Amylase breaks down carbohydrates, protease breaks down proteins, and lipase breaks down fats—they work together to help your body digest food more efficiently. The formula combines them to support overall digestive function.
Is this formula safe to use long-term?
No. Rhubarb and aloe ferox are stimulant laxatives that can cause potassium loss and other side effects with long-term use. This formula is intended for occasional digestive support, not daily, ongoing use. Talk with your doctor if you need lasting bowel support.
What are the most common side effects?
Mild abdominal cramping, diarrhea, nausea, and heartburn are common—mostly from the rhubarb, peppermint, and ginger. These usually ease once your body adjusts, or if you stop taking it. Rare allergic reactions to protease have been reported.
