HelloPharmacist Scorecard of Stm T5 To T9 by Thera-Zyme

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.

From our pharmacy team — supplement deep dive

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 6 of its 16 active ingredients.
  • “Proprietary Plant Enzyme Blend” is a proprietary blend — the label gives one combined amount (169 mg) without saying how much of each component you get.

Stm T5 To T9 contains 16 active ingredients, most of them digestive enzymes designed to help break down food. You'll find vitamin B12 for energy and nerve health, along with plant enzymes including protease and lipase (which digest protein and fat), amylase, glucoamylase, cellulase, hemicellulase, diastase, alpha-galactosidase, and catalase.

The product also includes botanical ingredients — marshmallow, slippery elm, papaya, and mastic tree — traditionally used to support digestive comfort. Phytase is listed as an inactive ingredient along with the vegetable capsule itself.

Does it work?

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
Not assessable

We hold no graded evidence for this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: pH balancing support.
  • Our graded evidence for these ingredients doesn't cover that particular purpose.

The evidence we hold shows mixed findings. Vitamin B12 is effective for B12 deficiency, Imerslund-Grasbeck disease (a rare absorption disorder), and likely effective for cyanide poisoning; it's possibly effective for canker sores and a nerve pain condition called postherpetic neuralgia.

Mastic tree is possibly effective for indigestion. For the other ingredients in this product — marshmallow, protease, lipase, slippery elm, papaya, and the various enzymes — we don't have established evidence of effectiveness for the conditions they're traditionally used for.

The data shows insufficient reliable evidence to rate them.

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 6 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.

Vitamin B12 is generally very well tolerated with no established upper limit, and it's considered safe in pregnancy and while breastfeeding. Most other ingredients are generally well tolerated for short-term use, though safety data vary.

Marshmallow, slippery elm, mastic tree, and papaya should be avoided in pregnancy and breastfeeding due to insufficient safety information. Protease may cause digestive upset or allergic reactions and should be avoided in pregnancy unless prescribed.

Lipase is generally well tolerated but should be used with medical guidance in pregnancy and breastfeeding. Allergic reactions are possible with papaya (especially in people with latex allergy) and slippery elm.

Protease, found in laundry detergents, has rarely caused allergic reactions with occupational exposure.

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?
  • 4 of the 7 matched ingredients can interact with medications — Papaya, Marshmallow, Vitamin B12, Slippery Elm.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications; lithium.
  • For scale: 2,069 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 against this product if you take oral drugs of any kind (slippery elm and marshmallow may slow absorption — Moderate for slippery elm, Minor for marshmallow), blood sugar medications (papayaModerate), blood thinners like warfarin (papaya and marshmallow — Moderate and Minor), lithium for mood disorders (marshmallow — Moderate), the heart drug amiodarone (papaya — Moderate), thyroid medication like levothyroxine (papaya — Moderate), or metformin for diabetes (vitamin B12Minor). No interactions are documented for protease, lipase, mastic tree, or the other enzymes we could check.

Each ingredient & the kinds of drugs it affects

For each ingredient in Stm T5 To T9 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

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

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

Vitamin B121 drug type · 20 drugs

Metformin (Glucophage)

Metformin, a common medication used to manage type 2 diabetes, has been associated with lower vitamin B12 levels in some individuals. Prolonged use of metformin can interfere with the absorption of B12 in the digestive system, potentially leading to a deficiency in this essential vitamin.

Stm T5 To T9 by Thera-Zyme: Common Questions

Does Stm T5 To T9 by Thera-Zyme interact with any medications?
Yes. Based on its ingredients, Stm T5 To T9 has a known interaction with 2,068 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Stm T5 To T9 contains 16 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 really help with digestion?
The evidence we hold shows insufficient reliable data for most of the enzymes and herbs in this blend. Mastic tree is possibly effective for indigestion, but for the others — marshmallow, slippery elm, papaya, and the various enzymes — we don't have solid proof they work for digestive complaints. Your mileage may vary, and a pharmacist can help you figure out if it's right for your specific situation.
Can I take this if I'm pregnant or breastfeeding?
Not all ingredients are safe to use during pregnancy and breastfeeding. Marshmallow, slippery elm, mastic tree, and papaya should be avoided because there isn't enough safety data. Vitamin B12 is considered safe at normal recommended amounts in both pregnancy and breastfeeding. Protease and lipase have limited safety data — talk with your doctor or midwife before use.
What is B12 in this product for?
Vitamin B12 supports energy, nerve health, and normal red blood cell function. This product includes it as part of the active ingredient mix, though the doses in enzyme blends are often modest compared to dedicated B12 supplements.
Will this interfere with my diabetes medication?
Yes — papaya can have additive effects with antidiabetes drugs and may change how they work. Vitamin B12 can also interact with metformin by lowering B12 levels over time. Run your exact medications through the checker on this page before starting.
What does 'enzyme blend' mean?
These are proteins that help break down different parts of food — protease breaks down protein, lipase handles fat, amylase works on starch, and so on. This product stacks several of them together, along with plant ingredients, to support overall digestion.
Can I take this with my other medications?
It depends on what you take. Slippery elm and marshmallow can slow how your body absorbs oral drugs if taken at the same time, so spacing them out 30–60 minutes apart helps. Several ingredients have other interactions too — use the medication checker below with your exact prescriptions.
