HelloPharmacist Scorecard of A.D.P. by Biotics Research Corporation

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 12, 2026

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.D.P. contains one active ingredient: oregano. This is the concentrated or extract form of the culinary herb, making it stronger than what you'd season food with.

The product also contains several inactive ingredients — cellulose, methylcellulose, potassium sorbate, stearic acid, an emulsifier base, and silica — which are fillers, binders, and flow agents used to form and preserve 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 Oregano's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: oregano extract for digestive and respiratory support.
  • We looked for evidence on: Bronchitis, Cough, Dyspepsia, Intestinal parasite infection, Rhinosinusitis, Upper respiratory tract infection (URTI) — and 2 related terms.
  • The closest evidence on file: Oregano is rated "Insufficient Reliable Evidence To Rate" for Bronchitis (Natural Medicines).
  • Also on file: Oregano is rated "Insufficient Reliable Evidence To Rate" for Upper respiratory tract infection (URTI), Cough, Dyspepsia, Intestinal parasite infection, and more.

The evidence for oregano in treating acne, bronchitis, asthma, headache, or upper respiratory tract infection is insufficient in our data. That doesn't mean it doesn't work; it means reliable clinical evidence hasn't been established yet.

If you're considering this for one of those conditions, talk with your doctor or pharmacist about whether the research supports its use for you.

The evidence, ingredient by ingredient Oregano

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.

Oregano from food is well tolerated, but this supplement is a concentrated form — much stronger and less well studied than culinary amounts. The most common side effect is gastrointestinal upset.

Rare but serious allergic reactions, including anaphylaxis, have been reported; if you've never had oregano before, watch for signs of allergy. During pregnancy, the safety data advises against medicinal or supplement amounts of oregano, though normal food amounts are likely fine.

While breastfeeding, the safety of supplements hasn't been established — stick to food amounts and talk with your doctor or pharmacist for personalized guidance.

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?
  • 1 of the 1 matched ingredient can interact with medications — Oregano.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications.
  • For scale: 208 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 exact medications if you take blood thinners or antiplatelet drugs (like warfarin, aspirin, or clopidogrel) — oregano may increase bleeding risk. Also double-check if you take diabetes medications, as oregano might lower your blood sugar further.

Use the medication checker on this page to verify before you start.

The bottom line

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

Oregano supplement might help with certain conditions, but the evidence isn't solid yet. If you take blood thinners, antiplatelet drugs, or diabetes medications, you'll want to check with us first — oregano may affect how they work.

Pregnant people should avoid medicinal amounts. Talk with your pharmacist before starting, especially if you take any regular medications.

A.D.P. by Biotics Research Corporation: Common Questions

Does A.D.P. by Biotics Research Corporation interact with any medications?
Yes. Based on its ingredients, A.D.P. has a known interaction with 208 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
A.D.P. 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.
Is oregano supplement safe to take during pregnancy?
The safety data advises against medicinal or supplement amounts of oregano during pregnancy. Normal food amounts — like oregano in your cooking — are likely fine. If you're pregnant or planning to be, talk with your doctor or pharmacist before taking this product.
What are the side effects of oregano supplements?
The most common side effect is stomach upset. Allergic reactions are rare but have been reported, ranging from mild (itching or rash) to serious (anaphylaxis in sensitive people). Since this is a concentrated form, not much is known about long-term safety at higher doses.
Can oregano help with colds or bronchitis?
We don't have reliable evidence yet showing oregano works for colds, bronchitis, asthma, or respiratory infections. The science on this is still being studied.
Is there a difference between oregano in cooking and oregano supplements?
Yes. This supplement is a concentrated extract — much stronger than the oregano you'd sprinkle on pizza. Food amounts are well tolerated, but supplement doses are less studied and carry the interaction risks we've flagged.
Can I take this if I have a shellfish or plant allergies?
Oregano is in the mint family (Lamiaceae). If you've had allergic reactions to mint, thyme, or other plants in that family, you should be cautious. Allergic reactions to oregano itself have been reported. Talk with your pharmacist if you have multiple plant allergies.
