HelloPharmacist Scorecard of Vegan DigestAway Maximum Potency by Solaray

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 20 active ingredients.
  • “Digestive Support Blend” is a proprietary blend — the label gives one combined amount (70 mg) without saying how much of each component you get.
  • “Vegan Digestaway Enzyme Blend” is a proprietary blend — the label gives one combined amount (500 mg) without saying how much of each component you get.

Vegan DigestAway Maximum Potency is a 20-ingredient digestive enzyme formula. The active ingredients include L-glutamine (an amino acid), a mix of digestive enzymes — lactase, cellulase, pectinase, invertase, glucoamylase, xylanase, maltase, beta-glucanase, phytase, hemicellulase, alpha-galactosidase, protease, and lipase — along with botanical extracts: ginger, slippery elm, aloe vera gel, papaya, and marshmallow.

The remaining ingredients are inactive: maltodextrin, cellulose, magnesium stearate, and silica (binders and fillers).

Does it work?

Strong 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

This product doesn't appear to be marketed for a specific use, so we graded its ingredients' overall clinical evidence instead.

Strong

Strong clinical evidence supports its ingredients for:

Why this rating?
  • The label markets general wellness (“Digestion support”), not a specific health condition, so there is no single claim to grade against clinical-evidence data.
  • Since the label doesn't commit to one use, we graded the ingredients' overall clinical evidence instead.
  • On file: Lactose intolerance — rated "Effective" (Lactase) (Natural Medicines).
  • On file: Sickle cell disease — rated "Effective" (Glutamine) (Natural Medicines).
  • On file: Acne — rated "Possibly Effective" (Aloe) (Natural Medicines).
  • On file: HIV/AIDS-related wasting — rated "Possibly Effective" (Glutamine) (Natural Medicines).
  • On file: Burns — rated "Possibly Effective" (Aloe) (Natural Medicines).

The evidence for this product's ingredients is mixed and mostly limited. Lactase is effective for lactose intolerance.

Ginger is possibly effective for pregnancy-related nausea and vomiting, menstrual cramps (dysmenorrhea), and osteoarthritis, though it's possibly ineffective for exercise-induced muscle soreness and chemotherapy-related nausea. Aloe is possibly effective for acne, obesity, diabetes, psoriasis, burns, and constipation.

For L-glutamine, phytase, slippery elm, protease, papaya, marshmallow, and lipase, the evidence we hold doesn't establish their effectiveness for any condition — these are rated insufficient reliable evidence to rate or have no ratings.

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 9 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.

L-glutamine is likely safe in pregnancy and lactation but is generally well tolerated in healthy adults; people with kidney or liver disease should use it only under medical supervision. Common side effects include belching, bloating, constipation, diarrhea, flatulence, nausea, and vomiting.

Lactase is likely safe in pregnancy and lactation and generally well tolerated; a rare case of allergic contact dermatitis has been reported in an occupational setting. Ginger is generally well tolerated at typical food and supplement amounts; common side effects include abdominal discomfort, burping, diarrhea, and heartburn — higher doses (5 grams per day and above) increase the risk of side effects.

While ginger is often used for morning sickness, check with your doctor first. Slippery elm is generally well tolerated for short-term use but has limited safety data; avoid during pregnancy and breastfeeding due to insufficient information.

Aloe gel is generally well tolerated, but oral aloe latex (the strong yellow substance) can cause serious side effects — avoid by mouth during pregnancy because it may stimulate the uterus and act as a strong laxative, and avoid while breastfeeding. Phytase safety during pregnancy and breastfeeding has not been well studied; use caution.

Protease is generally well tolerated but should be avoided during pregnancy unless prescribed. Papaya fruit is safe as food, but unripe papaya, papaya latex, and seeds should be avoided; some sources caution against large amounts during pregnancy.

Marshmallow is generally well tolerated short-term but should be avoided during pregnancy and breastfeeding due to insufficient safety information. Lipase is generally well tolerated but people with serious digestive conditions should use it only under medical guidance.

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

Why this rating?
  • 6 of the 10 matched ingredients can interact with medications — Papaya, Aloe, Marshmallow, Glutamine, Ginger, among others.
  • The most serious interaction on file is rated Major.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; seizure medications; immunosuppressants / transplant drugs; diabetes medications; heart-rhythm medications; lithium.
  • For scale: 2,144 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, double-check with a pharmacist or doctor if you take any of these: digoxin or other heart medications; blood thinners or antiplatelet drugs (warfarin, aspirin, clopidogrel); diabetes medications; diuretics; anticonvulsants; nifedipine; losartan; levothyroxine; amiodarone; cancer drugs; or lithium. Also check if you take any oral medications regularly, since several ingredients may interfere with absorption.

For each ingredient in Vegan DigestAway Maximum Potency 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.

Marshmallow3 drug types · 2,040 drugs

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.

Likelihood Probable Evidence D
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.

Likelihood Unlikely Evidence D
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.

Likelihood Possible Evidence D
Marshmallow full monograph & interactions

Slippery Elm1 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 full monograph & interactions

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

Aloe Vera Gel7 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 Gel full monograph & interactions

Papaya4 drug types · 92 drugs

Amiodarone (Cordarone)

Theoretically, papaya extract may increase the levels and clinical effects of amiodarone.
Animal research in rats shows that a single oral dose of papaya extract, as well as multiple doses of papaya extract daily over 14 days, prior to a single dose of amiodarone delays the time to maximum amiodarone concentration. However, only the 14-day papaya extract regimen increases systemic amiodarone exposure by 60% to 70%. This interaction has not been reported in humans.

Likelihood Probable Evidence D
Antidiabetes Drugs

Concomitant use of antidiabetic drugs with fermented papaya can produce additive effects. It is unclear if other forms of papaya have the same effect.
A small low-quality clinical study in patients with type 2 diabetes who are taking glibenclamide shows that taking a fermented papaya preparation 3 grams daily for 2 months decreases fasting and postprandial blood glucose levels when compared to baseline. Additionally, of the 25 patients in the study, 9 required a reduction in glibenclamide dose.

Likelihood Probable Evidence B
Levothyroxine (Synthroid, Others)

Theoretically, consuming large quantities of papaya fruit can reduce the clinical effects of levothyroxine.
In one case-report, a 37-year-old male with a history of thyroidectomy who was stabilized on levothyroxine for 5 years presented with hypothyroidism after consuming 5-6 papaya fruits daily for 14 days during vacation. In a controlled re-challenge test involving 5-6 papayas daily, the patient remained euthyroid for 7 days, but developed mild hypothyroidism after 14 days. Both times, thyroid levels normalized 40-45 days after discontinuing papaya.

Likelihood Possible Evidence D
Warfarin (Coumadin)

Theoretically, concomitant use of warfarin with papain-containing papaya extract might increase the effects and side effects of warfarin.
In one case report, a patient previously stable on warfarin was found to have an international normalization ratio (INR) of 7.4, which was attributed to ingestion of a supplement containing papain from papaya extract.

Likelihood Possible Evidence D
Papaya full monograph & interactions

L-Glutamine1 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.

Vegan DigestAway Maximum Potency by Solaray: Common Questions

Does Vegan DigestAway Maximum Potency by Solaray interact with any medications?
Yes. Based on its ingredients, Vegan DigestAway Maximum Potency has a known interaction with 2,143 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?
Vegan DigestAway Maximum Potency contains 20 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 real aloe, and is it safe?
Yes, it contains aloe vera gel, which is generally well tolerated. However, the product also contains aloe in a form that could have laxative effects, so it interacts with heart medications and blood thinners. If you take digoxin or warfarin, ask your pharmacist before using this product.
Can I take this while pregnant?
There isn't enough safety data for several ingredients in pregnancy — L-glutamine, slippery elm, papaya, and marshmallow all lack reliable pregnancy safety information. Ginger is sometimes used for morning sickness but should be kept moderate and discussed with your doctor first. Talk to your OB or pharmacist before starting.
What does the ginger in here do?
Ginger in this formula is included for digestive support. It's possibly effective for nausea and vomiting (especially pregnancy-related) and may help with menstrual cramps and joint soreness. At typical supplement doses it's generally well tolerated, though it can cause mild side effects like burping, diarrhea, and heartburn.
Will this interfere with my other medications?
Potentially, yes — several ingredients interact with common medications including diabetes drugs, heart drugs, and blood thinners. Use the medication checker on this page to search your exact prescriptions before starting.
Is there lactose in this product?
The product contains lactase, which is an enzyme that breaks down lactose, not lactose itself. The inactive ingredients do not list lactose. However, if you have a severe milk allergy (not just lactose intolerance), check the label or contact the manufacturer to confirm.
What are all these enzyme names, and do they work?
These are digestive enzymes — proteins that break down different food components: amylase breaks down carbs, protease breaks down proteins, lipase breaks down fats, and others break down specific plant fibers and sugars. For most of them, we don't have strong evidence they work as supplements, but they're generally well tolerated.
