HelloPharmacist Scorecard of GI Repair Powder by Vital Nutrients

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.

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 1 of its 9 active ingredients.
  • “Proprietary Blend” is a proprietary blend — the label gives one combined amount (5.11 Gram(s)) without saying how much of each component you get.

GI Repair Powder contains 9 ingredients, including a proprietary blend. The active components are Xylitol (a sugar alcohol used in some dental products), Rutin (a plant compound), Zinc, N-Acetyl Glucosamine (a compound derived from shellfish), L-Glutamine (an amino acid), Slippery Elm Powder (inner bark), and Aloe Vera leaf inner fillet extract.

We could not check Methylsulfonylmethane and Colostrum from our available data. The product contains no inactive fillers or other listed ingredients beyond the actives.

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: Support for gastrointestinal health and repair.
  • We looked for evidence on: Constipation, Diarrhea, Crohn disease, Cystic fibrosis, Chemotherapy-induced diarrhea, Antiretroviral-associated diarrhea — and 4 related terms.
  • The strongest evidence on file: Aloe is rated "Possibly Effective" for Constipation (Natural Medicines).
  • Also on file: Glutamine is rated "Possibly Ineffective" for Crohn disease, Radiation-induced diarrhea.
  • Also on file: Zinc is rated "Possibly Ineffective" for Cystic fibrosis.

Evidence varies widely by ingredient. Xylitol is likely effective for dental caries and possibly effective for ear infections (otitis media).

Zinc is effective for zinc deficiency and likely effective for Wilson disease. N-Acetyl Glucosamine is likely effective for osteoarthritis.

Aloe Vera gel is possibly effective for acne, burns, and several other conditions. Glutamine is effective for sickle cell disease and possibly effective for recovery after surgery or critical illness.

For most other claimed uses—including Rutin for inflammatory bowel disease, Slippery Elm for constipation or diarrhea, and several others—the evidence in our data is insufficient to rate.

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 7 of the 7 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 7 of 7.
  • General safety write-ups exist for 7 of 7.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Xylitol is generally well tolerated in food amounts but can cause digestive upset (diarrhea, bloating, flatulence) at high doses of 30–40 grams and is extremely toxic to dogs. Zinc is well tolerated below 40 mg daily; higher doses may cause nausea, metallic taste, or abdominal discomfort, and long-term high-dose use raises concern for copper deficiency.

N-Acetyl Glucosamine is generally well tolerated orally but carries rare risk of allergic reactions including anaphylaxis; some cases of asthma flare-ups have been reported. Aloe Vera gel applied topically is well tolerated, but oral aloe latex can cause cramping and diarrhea and should be avoided in pregnancy and breastfeeding.

Rutin safety data for supplement doses are limited; it may cause headache, flushing, or rash in some people and is not recommended during breastfeeding. Glutamine is generally well tolerated in healthy adults but should be used only under medical supervision if you have kidney or liver disease.

Slippery Elm is generally well tolerated short-term but has limited long-term safety data; safety during pregnancy and breastfeeding is not well established.

Major identified

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

Why this rating?
  • 6 of the 7 matched ingredients can interact with medications — Rutin, Aloe, Glucosamine, Glutamine, Slippery Elm, among others.
  • The most serious interaction on file is rated Major.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; seizure medications; diabetes medications; heart-rhythm medications.
  • For scale: 2,093 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.

Check with your doctor or pharmacist before using this product if you take any of these: blood thinners or antiplatelet drugs (warfarin, aspirin), heart medications (digoxin), antibiotics (especially quinolone, tetracycline, or cephalexin types), penicillamine, HIV medications (ritonavir, integrase inhibitors like dolutegravir, or bictegravir-based combinations), chemotherapy drugs (cisplatin or topoisomerase II inhibitors), diabetes medications, anticonvulsant (seizure) drugs, diuretics, or stimulant laxatives. Slippery Elm may slow absorption of any oral medication, so spacing doses with other drugs may be necessary.

Slippery Elm, Powder1 drug type · 2,022 drugs

Oral Drugs

Theoretically, slippery elm may slow the absorption and reduce serum levels of oral drugs.
Slippery elm inner bark contains mucilage, which may interfere with the absorption of orally administered drugs.

Likelihood Possible Evidence D
Slippery Elm, Powder full monograph & interactions

Aloe Vera leaf inner fillet extract7 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.

Likelihood Possible Evidence D
Aloe Vera leaf inner fillet extract full monograph & interactions

N-Acetyl Glucosamine4 drug types · 170 drugs

Warfarin (Coumadin)

Glucosamine might increase the anticoagulant effects of warfarin and increase the risk of bruising and bleeding.
In two individual case reports, glucosamine/chondroitin combinations were associated with a significant increase in international normalized ratio (INR) in patients previously stabilized on warfarin. In one case, the increase in INR occurred only after tripling the dose of a glucosamine/chondroitin supplement from 500 mg/400 mg daily to 1500/1200 mg daily. Additionally, 20 voluntary case reports to the U.S. Food & Drug Administration (FDA) have linked glucosamine plus chondroitin with increased INR, bruising, and bleeding in patients who were also taking warfarin. There have also been 20 additional case reports to the World Health Organization (WHO) that link glucosamine alone to increased INR in patients taking warfarin. The mechanism of this interaction is unclear. Glucosamine is a small component of heparin, but is not thought to have anticoagulant activity; however, animal research suggests that it might have antiplatelet activity.

Likelihood Probable Evidence D
Topoisomerase Ii Inhibitors

Theoretically glucosamine may induce resistance to topoisomerase II inhibitors.
In vitro research suggests that glucosamine might induce resistance to etoposide (VP16, VePesid) and doxorubicin (Adriamycin) by reducing inhibition of topoisomerase II, an enzyme required for DNA replication in tumor cells. This effect has not been reported in humans.

Likelihood Possible Evidence D
Acetaminophen (Tylenol, Others)

Acetaminophen might interfere with the activity of glucosamine sulfate by interacting with the sulfate portion.
Anecdotal reports suggest that adding glucosamine to an acetaminophen regimen might decrease pain control in patients with osteoarthritis. Some research suggests that the sulfate portion of glucosamine sulfate might contribute to its effect in osteoarthritis. Since acetaminophen metabolism requires sulfur and reduces serum sulfate concentrations, acetaminophen could theoretically interfere with the action of glucosamine sulfate. Conversely, the administration of sulfate could theoretically decrease the effectiveness of acetaminophen in sulfate-deficient people by increasing its clearance.

Likelihood Possible Evidence B
Antidiabetes Drugs

Despite initial concerns, it is unlikely that glucosamine will interfere with the effects of antidiabetes drugs.
In vitro and animal research has suggested that glucosamine might increase insulin resistance or decrease insulin production. This has raised concerns that taking glucosamine might worsen diabetes and decrease the effectiveness of diabetes drugs. However, clinical research suggests that glucosamine does not have adverse effects on blood glucose or glycated hemoglobin (HbA1C) in healthy, obese, or type 2 diabetes patients.

Likelihood Unlikely Evidence B
N-Acetyl Glucosamine full monograph & interactions

Rutin1 drug type · 86 drugs

Antidiabetes Drugs

Theoretically, taking rutin with antidiabetes drugs might increase the risk of hypoglycemia.
Animal research suggests that rutin has hypoglycemic effects.

Likelihood Possible Evidence D
Rutin full monograph & interactions

Zinc10 drug types · 67 drugs

Bictegravir/Emtricitabine/Tenofovir Alafenamide (Biktarvy)

Theoretically, zinc might decrease levels of bictegravir/emtricitabine/tenofovir alafenamide by reducing its absorption.
Advise patients that bictegravir/emtricitabine/tenofovir alafenamide should be taken at least 2 hours before or 6 hours after zinc containing products.

Likelihood Probable Evidence D
Cephalexin (Keflex)

Zinc might decrease cephalexin levels by chelating with cephalexin in the gut and preventing its absorption.
A pharmacokinetic study shows that zinc sulfate 250 mg taken concomitantly with cephalexin 500 mg decreases peak levels of cephalexin by 31% and reduces the exposure to cephalexin by 27%. Also, taking zinc sulfate 3 hours before cephalexin decreases peak levels of cephalexin by 11% and reduces the exposure to cephalexin by 18%. By decreasing cephalexin levels, zinc might increase the risk of treatment failure. This effect does not occur when zinc is taken 3 hours after the cephalexin dose. To avoid an interaction, advise patients take zinc sulfate 3 hours after taking cephalexin.

Likelihood Probable Evidence B
Cisplatin (Platinol-Aq)

Theoretically, zinc might interfere with the therapeutic effects of cisplatin.
Animal research suggests that zinc stimulates tumor cell production of the protein metallothionein, which binds and inactivates cisplatin. It is not known whether zinc supplements or high dietary zinc intake can cause clinically significant interference with cisplatin therapy. Cisplatin might also increase zinc excretion.

Likelihood Possible Evidence D
Integrase Inhibitors

Theoretically, taking zinc along with integrase inhibitors might decrease the levels and clinical effects of these drugs.
Zinc is a divalent cation. Pharmacokinetic studies have shown that other divalent cations such as calcium and iron can decrease blood levels of the integrase inhibitor dolutegravir through chelation.

Likelihood Possible Evidence D
Penicillamine (Cuprimine, Depen)

Zinc might reduce the levels and clinical effects of penicillamine.
By forming an insoluble complex with penicillamine, zinc interferes with penicillamine absorption and activity. Zinc supplements reduce the efficacy of low-dose penicillamine (0.5-1 gram/day), but do not seem to affect higher doses (1-2.75 gram/day), provided dosing times are separated. Advise patients to take zinc and penicillamine at least 2 hours apart.

Likelihood Probable Evidence B
Quinolone Antibiotics

Zinc can decrease the levels and clinical effects of quinolones antibiotics.
Quinolones form complexes with zinc in the gastrointestinal tract, reducing absorption of both the quinolone and zinc if taken at the same time. Advise patients to take these drugs at least 2 hours before, or 4-6 hours after, zinc supplements.

Likelihood Probable Evidence B
Ritonavir (Norvir)

Zinc modestly reduces levels of ritonavir.
Clinical research shows that zinc might reduce serum ritonavir levels by chelating with ritonavir in the gut and preventing its absorption. In patients with HIV, ritonavir is taken with atazanavir to prevent the metabolism and increase the effects of atazanavir. A pharmacokinetic study shows that, in patients being treated with atazanavir/ritonavir, co-administration of zinc sulfate (Solvazinc tablets) 125 mg as a single dose or as multiple daily doses for 2 weeks reduces plasma levels of ritonavir by about 16%. However, atazanavir levels still remains high enough to prevent HIV virus replication. Therefore, the decrease in ritonavir levels is not likely to be clinically significant.

Likelihood Probable Evidence B
Tetracycline Antibiotics

Zinc might reduce levels of tetracycline antibiotics.
Tetracyclines form complexes with zinc in the gastrointestinal tract, which can reduce absorption of both the tetracycline and zinc when taken at the same time. Taking zinc sulfate 200 mg with tetracycline reduces absorption of the antibiotic by 30% to 40%. Demeclocycline and minocycline cause a similar interaction. However, doxycycline does not seem to interact significantly with zinc. Advise patients to take tetracyclines at least 2 hours before, or 4-6 hours after, zinc supplements to avoid any interactions.

Likelihood Probable Evidence B
Amiloride (Midamor)

Amiloride can modestly reduce zinc excretion and increase zinc levels.
Clinical research shows that amiloride can reduce urinary zinc excretion, especially at doses of 10 mg per day or more. This zinc-sparing effect can help to counteract zinc losses caused by thiazide diuretics, but it is unlikely to cause zinc toxicity at usual amiloride doses. The other potassium-sparing diuretics, spironolactone (Aldactone) and triamterene (Dyrenium), do not seem to have a zinc-sparing effect.

Likelihood Probable Evidence B
Atazanavir (Reyataz)

Zinc modestly reduces levels of atazanavir, although this effect does not seem to be clinically significant.
Clinical research shows that zinc might decrease serum atazanavir levels by chelating with atazanavir in the gut and preventing its absorption. Although a single dose of zinc sulfate (Solvazinc tablets) 125 mg orally does not affect atazanavir concentrations in patients being treated with atazanavir/ritonavir, co-administration of zinc sulfate 125 mg daily for 2 weeks reduces plasma levels of atazanavir by about 22% in these patients. However, despite this decrease, atazanavir levels still remain at high enough concentrations for the prevention of HIV virus replication.

Likelihood Probable Evidence B
Zinc full monograph & interactions

L-Glutamine, Powder1 drug type · 50 drugs

Anticonvulsants

Theoretically, glutamine might antagonize the effects of anticonvulsant medications.
Glutamine is metabolized to the excitatory neurotransmitter glutamate. Glutamate might have antagonistic effects with anticonvulsant drugs. However, this interaction has not yet been reported in humans.

GI Repair Powder by Vital Nutrients: Common Questions

Does GI Repair Powder by Vital Nutrients interact with any medications?
Yes. Based on its ingredients, GI Repair Powder has a known interaction with 2,092 medications, including 3 rated major. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
GI Repair Powder 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.
Does this product contain any ingredients I might be allergic to?
N-Acetyl Glucosamine is derived from shellfish, so if you have a shellfish allergy, check with your pharmacist first. Glucosamine products have also been linked to rare allergic reactions including anaphylaxis in sensitive individuals. Slippery Elm pollen can trigger reactions in people with pollen allergies.
Can I take this if I'm pregnant or breastfeeding?
Safety data vary by ingredient. Glutamine is likely safe in pregnancy, but N-Acetyl Glucosamine and Aloe Vera are not recommended—Aloe may stimulate the uterus and acts as a strong laxative. Rutin safety in pregnancy is not established, and it should be avoided while breastfeeding. Talk with your doctor or pharmacist about whether this product is right for you during pregnancy or nursing.
Will this help my digestive problems?
The ingredients are intended to support GI health, but evidence for most of them in treating specific digestive complaints—constipation, diarrhea, or inflammatory bowel disease—is insufficient in our data. Glutamine is possibly effective for recovery after critical illness, and some ingredients like Slippery Elm have a history of traditional use for gut comfort, but we can't confirm effectiveness for your particular condition.
What side effects might I experience?
The most common are gastrointestinal: bloating, constipation, diarrhea, nausea, and cramping—especially from Xylitol at high doses or from Aloe. Zinc may cause a metallic taste. Rutin may cause headache or skin flushing. Most people tolerate the product well at recommended doses, but if you experience persistent GI upset, stop and talk to your pharmacist.
Is this safe for dogs?
No. Xylitol, one of the ingredients in this powder, is highly toxic to dogs and can cause serious illness or death. Keep this product away from pets.
Does Zinc in this product affect how antibiotics work?
Yes—Zinc can reduce absorption and lower blood levels of several antibiotic types, including quinolones, tetracyclines, and cephalexin. If you're taking an antibiotic, ask your pharmacist about spacing the doses at least 2–6 hours apart, depending on the antibiotic.
