HelloPharmacist Scorecard of Ultimate Digestive Complex by Puritan's Pride

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 2 of its 6 active ingredients.
  • “Proprietary Blend (Non-Nutrient/Non-Botanical)” is a proprietary blend — the label doesn't break down how much of each component you get.

This product contains six active ingredients: four live beneficial bacteria (probiotics) — Lactobacillus acidophilus NCFM, Bifidobacterium lactis Bl-04, Lactobacillus paracasei Lpc-37, and Bifidobacterium lactis Bi-07 — along with Alpha-Galactosidase (an enzyme) and GutGard Licorice extract. The probiotics are meant to support digestive and gut health, while the enzyme aids carbohydrate digestion.

The licorice extract has traditionally been used to soothe digestive discomfort. The capsules also contain vegetable cellulose and less than 2% of other inactive ingredients.

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: Digestive health and balance.
  • We looked for evidence on: Antibiotic-associated diarrhea, Bacterial vaginosis, Canker sores, Clostridioides difficile infection, Constipation, Dyspepsia — and 4 related terms.
  • The strongest evidence on file: Lactobacillus Acidophilus is rated "Possibly Effective" for Antibiotic-associated diarrhea (Natural Medicines).
  • Also on file: Lactobacillus Acidophilus is rated "Possibly Effective" for Bacterial vaginosis, Helicobacter pylori, Irritable bowel syndrome (IBS).
  • Also on file: Licorice is rated "Possibly Effective" for Canker sores.

For Lactobacillus acidophilus: the data shows it's possibly effective for irritable bowel syndrome (IBS), antibiotic-associated diarrhea, bacterial vaginosis, and helicobacter pylori infection. It's rated as possibly ineffective for atopic disease (eczema-type conditions), and the evidence isn't strong enough to rate it for acute respiratory distress syndrome.

For the licorice extract: it's possibly effective for canker sores and atopic dermatitis (eczema). The evidence is insufficient to rate it for Addison disease or asthma.

We have no effectiveness data on file for the other probiotic strains or the enzyme in this product.

The evidence, ingredient by ingredient Licorice Lactobacillus Acidophilus

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 2 of the 2 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 2 of 2.
  • General safety write-ups exist for 2 of 2.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Lactobacillus acidophilus is generally well tolerated in healthy adults and children, though it's wise to check with your doctor before use. Taking it with other probiotics may occasionally cause mild gastrointestinal side effects — epigastric discomfort, abdominal pain, bloating, flatulence, or diarrhea — but these are uncommon.

Rarely, live Lactobacillus organisms could theoretically cause infection in certain patients; most documented cases appear linked to bacteria moving from other body sites. Licorice extract is generally well tolerated in small food amounts, but the active compound glycyrrhizin can cause serious problems at high doses or with long-term use.

Most common side effects are headache, nausea, and vomiting. The safety data advises against licorice in pregnancy due to links to harmful effects, and there isn't enough reliable information to use it while breastfeeding.

Topically, contact rash can occur.

Side effects, ingredient by ingredient Licorice Lactobacillus Acidophilus

Meds to double-check

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?
  • 2 of the 2 matched ingredients can interact with medications — Lactobacillus Acidophilus, Licorice.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; heart-rhythm medications.
  • For scale: 1,187 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 your medications before using this product if you take digoxin (Lanoxin) or warfarin (Coumadin) — both have Moderate interactions with the licorice extract that may alter how well they work or increase risk. Also double-check if you're on loop diuretics (water pills), cancer drugs (cisplatin, paclitaxel), sedatives like midazolam (Versed), or antibiotics — the licorice or Lactobacillus acidophilus may interact.

Your pharmacist can search your exact prescriptions using the tool on this page.

The bottom line

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

This product may help with IBS, antibiotic-related diarrhea, or canker sores if you take Lactobacillus acidophilus. However, if you're on digoxin, warfarin, loop diuretics, cancer drugs, sedatives, or antibiotics, you need to check your exact medications before starting it — the licorice extract has several important interactions.

If you're pregnant or breastfeeding, talk to your pharmacist first.

GutGard Licorice extract18 drug types · 1,040 drugs

Antihypertensive Drugs

Theoretically, licorice might reduce the effects of antihypertensive drugs.
In human research, licorice increases blood pressure in a dose-dependent manner.

Likelihood Possible Evidence B
Cisplatin (Platinol-Aq)

Theoretically, licorice might reduce the effects of cisplatin.
In animal research, licorice diminished the therapeutic efficacy of cisplatin.

Likelihood Possible Evidence D
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.

Likelihood Possible Evidence D
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.

Likelihood Possible Evidence D
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.

Likelihood Possible Evidence D
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.

Likelihood Possible Evidence D
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.

Likelihood Possible Evidence D
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.

Likelihood Possible Evidence B
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.

Likelihood Possible Evidence D
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.

Likelihood Possible Evidence D
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.

Likelihood Possible Evidence D
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.

Likelihood Possible Evidence D
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.

Likelihood Possible Evidence B
P-Glycoprotein Substrates

Theoretically, licorice might decrease the absorption of P-glycoprotein substrates.
In vitro research shows that licorice can increase P-glycoprotein activity.

Likelihood Possible Evidence D
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.

Likelihood Possible Evidence D
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.

Likelihood Possible Evidence D
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.

Likelihood Possible Evidence D
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.

Likelihood Unlikely Evidence D
GutGard Licorice extract full monograph & interactions

Lactobacillus acidophilus NCFM1 drug type · 182 drugs

Antibiotic Drugs

Theoretically, taking Lactobacillus acidophilus with antibiotic drugs might decrease the effectiveness of L. acidophilus.
L. acidophilus preparations usually contain live and active organisms. Therefore, simultaneously taking antibiotics might kill a significant number of the organisms. Tell patients to separate administration of antibiotics and L. acidophilus preparations by at least two hours.

Ultimate Digestive Complex by Puritan's Pride: Common Questions

Does Ultimate Digestive Complex by Puritan's Pride interact with any medications?
Yes. Based on its ingredients, Ultimate Digestive Complex has a known interaction with 1,186 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Ultimate Digestive Complex contains 6 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.
What do the probiotics in this product do?
The live beneficial bacteria — Lactobacillus acidophilus and the two Bifidobacterium strains — are meant to support your gut health. The data shows they're possibly effective for conditions like IBS, antibiotic-related diarrhea, and bacterial vaginosis, and they're generally well tolerated in healthy people.
Can I take this with antibiotics?
You can, but there's a catch: antibiotics can kill the live organisms in the Lactobacillus acidophilus, which may reduce how well the probiotic works. It's best to separate them by a few hours. Ask your pharmacist for the timing that works best.
Is it safe to use this while pregnant?
The licorice extract in this product should be avoided in pregnancy because glycyrrhizin (its active compound) has been linked to harmful effects. There's no pregnancy safety data on file for the probiotics. Talk with your doctor or pharmacist to decide if this product is right for you.
What side effects might the probiotics cause?
Gastrointestinal side effects like bloating, gas, mild abdominal discomfort, or diarrhea can occur when taking Lactobacillus acidophilus with other probiotics, but these are uncommon. Most people tolerate it well.
Does this product have fillers?
It contains vegetable cellulose as an inactive ingredient, plus less than 2% of other inactive ingredients. So yes, like most capsules, it has a small amount of inert materials.
