HelloPharmacist Scorecard of Digestive Support by VitaScript
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
VitaScript's Digestive Support contains four active ingredients. Three are named individually: deglycyrrhizinated licorice root extract (a form of licorice with the strongest-acting compound removed), fennel, and aloe vera.
The fourth is a proprietary Digestive Lining Protection Blend, whose exact components and amounts aren't disclosed. The product also contains inactive ingredients — vegan capsule, cellulose, silica, and calcium stearate — which are fillers and binders that help form and stabilize the capsule.
Does it work?
Moderate evidence
The evidence for these ingredients is mixed. Deglycyrrhizinated licorice is possibly effective for canker sores and eczema (atopic dermatitis), but the data is insufficient to rate it for Addison disease or asthma.
Fennel is possibly effective for period cramps (dysmenorrhea), though evidence is insufficient for bronchitis, anxiety, bed-wetting, or cholera. Aloe is possibly effective for acne, diabetes, psoriasis, burns, constipation, and obesity — a broader range — but the Digestive Lining Protection Blend's effectiveness isn't established in our data because we don't know what it contains.
For marshmallow, evidence is insufficient across all conditions listed. If digestion support is your goal, the ingredients with the strongest evidence are aloe and fennel for specific conditions; talk with your pharmacist about whether this product matches what you're trying to address.
How safe is it?
Well-documented data
Deglycyrrhizinated licorice is generally well tolerated, though high doses or long-term use of regular licorice can cause serious problems — and the safety note advises against it in pregnancy and while breastfeeding. Fennel is generally safe as a food but concentrated supplements need more caution; avoid medicinal amounts in pregnancy and use food amounts only while breastfeeding.
Aloe is well tolerated topically, but oral aloe latex (the yellow substance under the leaf skin) can cause abdominal pain, cramping, and diarrhea, and poses risks in pregnancy and breastfeeding. Marshmallow is generally well tolerated for short-term use, but human safety data are limited, and it should be avoided in pregnancy and while breastfeeding.
The most common side effects from these ingredients are headache, nausea, vomiting, gastrointestinal discomfort, and photosensitivity; contact dermatitis can occur with topical use.
Meds to double-check
Major interaction found
Check with your pharmacist if you take any of these: heart medications like digoxin, blood thinners (warfarin or others), diabetes drugs, water pills (loop diuretics or other diuretics), birth control pills or hormone replacement therapy, lithium, cisplatin or paclitaxel (cancer drugs), ciprofloxacin (an antibiotic), or stimulant laxatives. The aloe–digoxin combination is the most serious; fennel with birth control and hormone therapy, and licorice with warfarin and heart drugs, are also significant.
Your pharmacist can help you space out doses or find alternatives if needed.
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.
This product may help with specific digestive or skin issues if its ingredients match your needs, but you must check it against any heart, blood-thinning, diabetes, or mood-stabilizing medications you take. If you're pregnant or breastfeeding, talk with your pharmacist first — several ingredients carry cautions.

For each ingredient in Digestive Support 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.
Marshmallow
Lithium
Theoretically, due to potential diuretic effects, marshmallow might reduce excretion and increase levels of lithium.
Marshmallow is thought to have diuretic properties. To avoid lithium toxicity, the dose of lithium might need to be decreased when used with marshmallow.
Anticoagulant/Antiplatelet Drugs
Theoretically, marshmallow flower might have antiplatelet effects.
Animal research suggests that marshmallow flower extract has antiplatelet effects. However, the root and leaf of marshmallow, not the flower, are the plant parts most commonly found in dietary supplements. Theoretically, use of marshmallow flower with anticoagulant/antiplatelet drugs can have additive effects, and might increase the risk for bleeding in some patients.
Oral Drugs
Theoretically, mucilage in marshmallow might impair absorption of oral drugs.
Marshmallow contains mucilage which can affect oral drug absorption. To avoid changes in absorption, take marshmallow 30-60 minutes after oral medications.
Deglycyrrhizinated Licorice Root Extract
Antihypertensive Drugs
Theoretically, licorice might reduce the effects of antihypertensive drugs.
In human research, licorice increases blood pressure in a dose-dependent manner.
Cisplatin (Platinol-Aq)
Theoretically, licorice might reduce the effects of cisplatin.
In animal research, licorice diminished the therapeutic efficacy of cisplatin.
Corticosteroids
Theoretically, concomitant use of licorice and corticosteroids might increase the side effects of corticosteroids.
Case reports suggest that concomitant use of licorice and oral corticosteroids, such as hydrocortisone, can potentiate the duration of activity and increase blood levels of corticosteroids. Additionally, in one case report, a patient with neurogenic orthostatic hypertension stabilized on fludrocortisone 0.1 mg twice daily developed pseudohyperaldosteronism after recent consumption of large amounts of black licorice.
Cytochrome P450 2B6 (Cyp2B6) Substrates
Theoretically, licorice might increase levels of drugs metabolized by CYP2B6.
In vitro research shows that licorice extract and glabridin, a licorice constituent, inhibit CYP2B6 isoenzymes. Licorice extract from the species G. uralensis seems to inhibit CYP2B6 isoenzymes to a greater degree than G. glabra extract in vitro. Theoretically, these species of licorice might increase levels of drugs metabolized by CYP2B6; however, these interactions have not yet been reported in humans.
Cytochrome P450 2C19 (Cyp2C19) Substrates
Theoretically, licorice might increase levels of drugs metabolized by CYP2C19.
In vitro, licorice extracts from the species G. glabra and G. uralensis inhibit CYP2C19 isoenzymes in vitro. Theoretically, these species of licorice might increase levels of drugs metabolized by CYP2C19; however, this interaction has not yet been reported in humans.
Cytochrome P450 2C8 (Cyp2C8) Substrates
Theoretically, licorice might increase levels of drugs metabolized by CYP2C8.
In vitro, licorice extract from the species G. glabra and G. uralensis inhibits CYP2C8 isoenzymes. Theoretically, these species of licorice might increase levels of drugs metabolized by CYP2C8; however, this interaction has not yet been reported in humans.
Cytochrome P450 2C9 (Cyp2C9) Substrates
Theoretically, licorice might increase or decrease levels of drugs metabolized by CYP2C9.
There is conflicting evidence about the effect of licorice on CYP2C9 enzyme activity. In vitro research shows that extracts from the licorice species G. glabra and G. uralensis moderately inhibit CYP2C9 isoenzymes. However, evidence from an animal model shows that licorice extract from the species G. uralensis can induce hepatic CYP2C9 activity. Until more is known, licorice should be used cautiously in people taking CYP2C9 substrates.
Cytochrome P450 3A4 (Cyp3A4) Substrates
Theoretically, licorice might increase or decrease levels of drugs metabolized by CYP3A4.
Pharmacokinetic research shows that the licorice constituent glycyrrhizin, taken in a dosage of 150 mg orally twice daily for 14 days, modestly decreases the area under the concentration-time curve of midazolam by about 20%. Midazolam is a substrate of CYP3A4, suggesting that glycyrrhizin modestly induces CYP3A4 activity. Animal research also shows that licorice extract from the species G. uralensis induces CYP3A4 activity. However, licorice extract from G. glabra species appear to inhibit CYP3A4-induced metabolism of testosterone in vitro. It is thought that the G. glabra inhibits CYP3A4 due to its constituent glabridin, which is a moderate CYP3A4 inhibitor in vitro and not present in other licorice species. Until more is known, licorice should be used cautiously in people taking CYP3A4 substrates.
Digoxin (Lanoxin)
Theoretically, concomitant use of licorice with digoxin might increase the risk of cardiac toxicity.
Overuse or misuse of licorice with cardiac glycoside therapy might increase the risk of cardiac toxicity due to potassium loss.
Diuretic Drugs
Theoretically, concomitant use of licorice with diuretic drugs might increase the risk of hypokalemia.
Overuse of licorice might compound diuretic-induced potassium loss. In one case report, a 72-year-old male with a past medical history of hypertension, type 2 diabetes, hyperlipidemia, arrhythmia, stroke, and hepatic dysfunction was hospitalized with severe hypokalemia and uncontrolled hypertension due to pseudohyperaldosteronism. This was thought to be provoked by concomitant daily consumption of a product containing 225 mg of glycyrrhizin, a constituent of licorice, and hydrochlorothiazide 12.5 mg for 1 month.
Estrogens
Theoretically, licorice might increase or decrease the effects of estrogen therapy.
Theoretically, licorice might interfere with estrogen therapy due to estrogenic and anti-estrogenic effects.
Loop Diuretics
Theoretically, loop diuretics might increase the mineralocorticoid effects of licorice.
Theoretically, loop diuretics might enhance the mineralocorticoid effects of licorice by inhibiting the enzyme that converts cortisol to cortisone; however, bumetanide (Bumex) does not appear to have this effect.
Midazolam (Versed)
Theoretically, licorice might decrease levels of midazolam.
In humans, the licorice constituent glycyrrhizin appears to moderately induce the metabolism of midazolam. This is likely due to induction of cytochrome P450 3A4 by licorice. Until more is known, licorice should be used cautiously in people taking midazolam.
P-Glycoprotein Substrates
Theoretically, licorice might decrease the absorption of P-glycoprotein substrates.
In vitro research shows that licorice can increase P-glycoprotein activity.
Paclitaxel (Abraxane, Onxol)
Theoretically, licorice might decrease plasma levels and clinical effects of paclitaxel.
Multiple doses of licorice taken concomitantly with paclitaxel might reduce the effectiveness of paclitaxel. Animal research shows that licorice 3 grams/kg given orally for 14 days before intravenous administration of paclitaxel decreases the exposure to paclitaxel and increases its clearance. Theoretically, this occurs because licorice induces cytochrome P450 3A4 enzymes, which metabolize paclitaxel. Notably, a single dose of licorice did not affect exposure or clearance of paclitaxel.
Warfarin (Coumadin)
Theoretically, licorice might decrease plasma levels and clinical effects of warfarin.
Licorice seems to increase metabolism and decrease levels of warfarin in animal models. This is likely due to induction of cytochrome P450 2C9 (CYP2C9) metabolism by licorice. Advise patients taking warfarin to avoid taking licorice.
Cytochrome P450 1A2 (Cyp1A2) Substrates
Theoretically, licorice might decrease the levels and clinical effects of CYP1A2 substrates.
In vitro research shows that licorice induces CYP1A2 enzymes.
Methotrexate (Trexall, Others)
Theoretically, licorice might increase levels of methotrexate.
Animal research suggests that intravenous administration of glycyrrhizin, a licorice constituent, and high-dose methotrexate may delay methotrexate excretion and increase systemic exposure, leading to transient elevations in liver enzymes and total bilirubin. This interaction has not yet been reported in humans.
Fennel
Anticoagulant/Antiplatelet Drugs
Theoretically, fennel might increase the risk of bleeding when used with antiplatelet or anticoagulant drugs.
Animal research suggests that fennel oil has antithrombotic and antiplatelet effects.
Ciprofloxacin (Cipro)
Theoretically, fennel might decrease the levels and clinical effects of ciprofloxacin.
Animal research shows that fennel reduces ciprofloxacin bioavailability by nearly 50%, possibly due to the metal cations such as calcium, iron, and magnesium contained in fennel. This study also found that fennel increased tissue distribution and slowed elimination of ciprofloxacin.
Contraceptive Drugs
Theoretically, taking large amounts of fennel might decrease the effects of contraceptive drugs due to competition for estrogen receptors.
Some constituents of fennel have estrogenic activity.
Cytochrome P450 3A4 (Cyp3A4) Substrates
Theoretically, fennel might increase levels of drugs metabolized by CYP3A4.
In vitro research suggests that fennel inhibits CYP3A4 enzyme activity. This effect has not been reported in humans.
Estrogens
Theoretically, taking large amounts of fennel might interfere with hormone replacement therapy due to competition for estrogen receptors.
Some constituents of fennel have estrogenic activity.
Tamoxifen (Nolvadex)
Theoretically, taking large amounts of fennel might decrease the antiestrogenic effect of tamoxifen.
Some constituents of fennel have estrogenic activity, which may interfere with the antiestrogenic activity of tamoxifen.
Aloe vera
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.
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.
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.
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.
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.
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.
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.
