HelloPharmacist Scorecard of Dairy Enzymes by Dr. Mercola

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

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Jul 11, 2026

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 0 of its 3 active ingredients.

This product has three active ingredients. Protease and lactase are both enzymes — proteins that help your body break down food.

Lactase specifically helps you digest milk sugar (lactose). Adenosine triphosphate (ATP) is a molecule your cells use for energy.

The capsule also contains organic rice, medium-chain triglycerides, and capsule material as inactive ingredients.

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
Strong

Clinical evidence supports at least one of this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: Support digestion of dairy products.
  • We looked for evidence on: Lactose intolerance, Dairy digestion, Gas and bloating from milk, Milk sensitivity.
  • The strongest evidence on file: Lactase is rated "Effective" for Lactose intolerance (Natural Medicines).

Lactase is effective for lactose intolerance — it helps your body digest milk products if you have trouble with them. The evidence isn't established in our data for lactase's use in colic or prematurity.

Adenosine triphosphate is listed as effective for certain heart rhythm problems (paroxysmal supraventricular tachycardia) and for cardiac stress testing, but those are clinical uses with the prescription injectable form given by doctors in a hospital or office, not oral supplement use. The safety and effectiveness of taking ATP as an oral supplement haven't been thoroughly evaluated.

There's no effectiveness data on file for protease in this form.

The evidence, ingredient by ingredient Proteolytic Enzymes (proteases) Lactase Adenosine

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 3 of the 3 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 3 of 3.
  • General safety write-ups exist for 3 of 3.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Protease and lactase are generally well tolerated by most adults. However, rarely, people can develop allergies to protease — occupational exposure to airborne protease has caused allergic rhinitis and asthma in some workers, and case reports exist of contact dermatitis and allergic rhinitis from powdered lactase.

Both can occasionally cause digestive upset. Adenosine triphosphate has limited safety data as an oral supplement — the prescription injectable form used in hospitals can cause chest pain, dizziness, shortness of breath, flushing, headache, and low blood pressure, but oral or intramuscular use hasn't been thoroughly studied.

Safety in pregnancy is not established for protease or adenosine triphosphate; lactase is likely safe in pregnancy. For breastfeeding, lactase has limited data but acts only in the gut; protease and adenosine triphosphate lack sufficient safety information.

Talk with your doctor or pharmacist before use during pregnancy or breastfeeding.

Meds to double-check

Major interaction found
Known Interaction Concern · database check
Major identified

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

Why this rating?
  • 1 of the 3 matched ingredients can interact with medications — Adenosine.
  • The most serious interaction on file is rated Major.
  • For scale: 47 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.

If you take dipyridamole (Persantine) for your heart, do not use this product without stopping the medication several days beforehand — the interaction is serious. Also double-check if you're on carbamazepine (Tegretol) for seizures, or if you regularly take caffeine, aminophylline, or theophylline.

Altogether, these interactions span 47 individual medications.

The bottom line

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

This product may help if you have trouble digesting lactose. Before you start, check your medications — especially if you take dipyridamole, carbamazepine, or caffeine-containing drugs.

The adenosine triphosphate component has limited evidence as an oral supplement. Talk with your pharmacist about whether it's right for you.

Adenosine Triphosphate3 drug types · 47 drugs

Dipyridamole (Persantine)

Dipyridamole can increase the therapeutic and toxic effects of adenosine.
Dipyridamole decreases the metabolism of adenosine. Intravenous infusion of adenosine in patients who are taking dipyridamole can cause dizziness, bradycardia, and syncope. Dipyridamole should be discontinued for several days prior to a cardiac stress test using adenosine.

Likelihood Likely Evidence D
Carbamazepine (Tegretol)

Carbamazepine might increase the risk of heart block when used concomitantly with adenosine.
Carbamazepine and adenosine can both cause heart block. Giving them concurrently might produce an additive effect.

Likelihood Possible Evidence D
Methylxanthines

Methylxanthines are competitive antagonists of adenosine and can block its pharmacologic effects.
The methylxanthines, aminophylline, caffeine, and theophylline, can block the effects of adenosine by acting as competitive antagonists at adenosine cell surface receptors. It is recommended that methylxanthines be avoided for 24 hours prior to cardiac stress tests.

Yes — lactase, one of the three active ingredients, is effective for lactose intolerance. It helps your body break down milk sugar so you can digest dairy products more comfortably.
Is it safe to use while pregnant?
Lactase is likely safe during pregnancy. However, protease and adenosine triphosphate don't have established safety data in pregnancy. Talk with your doctor or pharmacist before using this product if you're pregnant.
Can I take this while breastfeeding?
Lactase acts only in the gut and has limited data but is considered safer. Protease and adenosine triphosphate lack sufficient safety information during breastfeeding. Check with your doctor or pharmacist first.

What does each ingredient do?
Protease and lactase are digestive enzymes — they break down protein and milk sugar, respectively. Adenosine triphosphate is an energy molecule your cells use, though its role in an oral supplement form isn't well established.
