HelloPharmacist Scorecard of A.T.P. 25 mg by Montiff

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

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

A.T.P. 25 mg contains one active ingredient: adenosine triphosphate (ATP), a naturally occurring molecule in your cells that plays a role in energy production and certain heart and blood-vessel functions.

The tablet also includes several inactive ingredients — dicalcium phosphate, cellulose, vegetable stearine, cellulose acetate phthalate, croscarmellose sodium, silica, diethyl phthalate, magnesium stearate, and poloxamer — which serve as binders and fillers to form the tablet.

Does it work?

Not established
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 established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use — see Adenosine's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: Energy and cellular function support.
  • We looked for evidence on: Athletic performance, muscle energy, cellular ATP production, exercise performance.
  • The closest evidence on file: Adenosine is rated "Insufficient Reliable Evidence To Rate" for Athletic performance (Natural Medicines).

Adenosine triphosphate is considered effective for paroxysmal supraventricular tachycardia (a type of rapid, irregular heartbeat that starts suddenly) and for cardiovascular disease diagnosis. These ratings come from the prescription injectable form, which is medically powerful and administered only by healthcare professionals.

The data on the oral supplement version that you'd be taking is more limited.

The evidence, ingredient by ingredient 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 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

This is where you need to be cautious. The prescription injectable form of adenosine can cause serious cardiovascular and respiratory side effects — chest pain, dizziness, shortness of breath, facial flushing, headache, low blood pressure, nausea, and tingling are common; rare but severe effects include arrhythmias (irregular heartbeats), cardiac arrest, and heart attack.

When adenosine is taken orally or as an intramuscular injection, no adverse effects have been reported, but a thorough safety evaluation hasn't been done. The safety data advises against using this supplement during breastfeeding, and there isn't enough information about safety in pregnancy to know either way — talk with your doctor or pharmacist if you're pregnant, planning to become pregnant, or breastfeeding.

Side effects, ingredient by ingredient Adenosine

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 1 matched ingredient 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.

Check with your pharmacist before taking this product if you use dipyridamole (Persantine) — it's a Major interaction and can amplify adenosine's effects. Carbamazepine (Tegretol) is a Moderate concern due to added risk of heart block.

Avoid methylxanthines like caffeine, theophylline, and aminophylline for 24 hours before taking adenosine, as they can block its effects.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Major medication interactions have been identified, and safety information is well characterized.

This product is based on a powerful prescription heart medication, and while the oral supplement form hasn't shown reported side effects, the evidence supporting its safety is limited. If you have a heart condition or take any heart or blood-vessel medications — especially dipyridamole, carbamazepine, or caffeine-containing products — check with your pharmacist before starting.

Each ingredient & the kinds of drugs it affects

For each ingredient in A.T.P. 25 mg with known interactions, here are the types of medications it can affect. Open any type for the detail — or search your exact drug in the checker above.

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.

A.T.P. 25 mg by Montiff: Common Questions

Does A.T.P. 25 mg by Montiff interact with any medications?
Yes. Based on its ingredients, A.T.P. 25 mg has a known interaction with 47 medications, including 2 rated major. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
A.T.P. 25 mg contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism 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 is adenosine triphosphate, and what does it do in this product?
Adenosine triphosphate (ATP) is a molecule that naturally occurs in your cells and helps with energy production. In this supplement, it's dosed at 25 mg per tablet and is believed to support heart and blood-vessel function — though the evidence for the oral supplement form is more limited than for the prescription injectable version.
Is this supplement safe to take if I'm pregnant or breastfeeding?
The safety data advises against use while breastfeeding. For pregnancy, there isn't enough information to know if it's safe or not. Talk with your doctor or pharmacist for personalized advice if you're pregnant, trying to become pregnant, or nursing.
Can I take this if I drink a lot of coffee or use caffeine supplements?
Caffeine (a methylxanthine) can block the effects of adenosine by competing for the same cell receptors. It's recommended you avoid caffeine and other methylxanthines like theophylline for 24 hours before taking this product.
What are the side effects of this oral supplement?
When adenosine is taken orally, no adverse effects have been reported in the data we have. However, a thorough safety evaluation hasn't been completed, so the full picture of side effects isn't yet clear.
Does this product actually work for heart conditions?
Adenosine triphosphate is considered effective for paroxysmal supraventricular tachycardia (a type of fast, irregular heartbeat) and cardiovascular diagnosis. That said, these ratings come mostly from the prescription injectable form; the evidence for the oral supplement is more limited.
