The bottom line No known interaction

We found no known interaction between Maqui and Olaparib in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first.

Maqui and Olaparib

We checked these two against our interaction database. Here is what we found.

No Known Interaction Found

We did not find a documented interaction between Olaparib and Maqui in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.

If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.

Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

Maqui safety at a glance

Maqui overall Use caution Likely safe in food amounts, but supplement safety has not been well studied.
Pregnancy Avoid Not enough safety information, so it is best to avoid supplement amounts.
Breastfeeding Avoid Not enough safety information, so it is best to avoid supplement amounts.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

How we checked

Why No Interaction Is Listed for Olaparib

Interactions in our licensed database are recorded against drug classes, not just single drug names. Olaparib is filed under 2 classifications — cytochrome p450 3a4 (cyp3a4) substrates, oral drugs. Maqui has documented interactions with 1 drug class — the most serious being antidiabetes drugs (minor) — and none of Olaparib’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

What Olaparib’s Own FDA Label Lists

This is not an interaction — none of it involves Maqui. These are the most notable effects listed in the ADVERSE REACTIONS section of Olaparib’s own FDA label, for the medication by itself. Knowing the drug’s own list makes it easier to work out the likely cause if something new turns up while you take both. 8 of them are worth acting on rather than waiting out — marked below.

  • Blood clots Worth acting on
  • Anemia Worth acting on mentioned in 7.8% of FDA reports for Olaparib
  • A low platelet count Worth acting on
  • Raised blood pressure Worth acting on
  • Shortness of breath Worth acting on
  • A low white blood cell count Worth acting on
  • Liver problems Worth acting on
  • A higher chance of infection Worth acting on
  • A change in taste
  • Mouth irritation or sores

Showing the 10 most notable of 23 label-listed effects — ranked by how unusual each one is across medicines generally, with serious effects weighted up.

From the ADVERSE REACTIONS section of the FDA label for Olaparib. Read the label on DailyMed › Where a percentage is shown, it is the share of 20,798 voluntary FDA FAERS reports for Olaparib that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Maqui’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Maqui side to compare — that is a limit of the record, not a statement that Maqui has no side effects.

Everything else you take

See Every Supplement That Interacts With Olaparib

This page covers Maqui only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Olaparib page lists 138 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Grapefruit (major), St. John's Wort (major), Acacia Rigidula (moderate) and Adrafinil (moderate).

By severity: 3 major · 94 moderate · 41 minor.

From our pharmacist’s overview on the Olaparib page

“Grapefruit is the first thing to drop if you take Olaparib (Lynparza). It blocks CYP3A4, the liver enzyme that clears this cancer drug, so levels can climb and side effects with them.”

About Maqui

What is Maqui?

  • Antioxidant support
  • Blood sugar support
  • Eye health and dry eye
  • Anti-inflammatory support
  • Heart health

Maqui is a dark purple berry from Chile that is very rich in antioxidant plant pigments called anthocyanins. Early research suggests it may help with things like blood sugar, dry eye, and inflammation, but the human evidence is still limited and far from proven. It is generally well tolerated as a food, but talk with your pharmacist or doctor before using concentrated supplements.

Aristotelia chilensis · Elaeocarpaceae · Berries (fruit); leaves are used traditionally · Capsules, powder, juice, extracts, dried berries

An interaction check asks whether these two react with each other — it does not ask whether Maqui is a good idea for someone in your situation. Here is what our Maqui record says about it on its own.

Maqui: dosing

There is no official or well-established dose for maqui. Doses used in research have varied widely depending on whether the product was a juice, powder, or standardized extract, so it is hard to recommend a single amount.The best approach is to follow the directions on the product label and not exceed them.

About Olaparib

What Is Olaparib Used For?

Brand name: Lynparza

Lynparza (olaparib) is used to treat adults with certain ovarian, fallopian tube, or primary peritoneal cancers that carry BRCA or other DNA-repair gene mutations — both as a maintenance therapy after platinum-based chemotherapy (including in combination with bevacizumab for some patients) and for recurrent disease. It is also approved for HER2-negative breast cancer with a germline BRCA mutation, both in early high-risk disease (adjuvant setting) and in metastatic disease.

Lynparza is additionally used as maintenance therapy for adults with germline BRCA-mutated metastatic pancreatic adenocarcinoma whose disease has not progressed on first-line platinum-based chemotherapy, and for adults with certain gene-mutated metastatic castration-resistant prostate cancer — either alone (after prior enzalutamide or abiraterone) or in combination with abiraterone and prednisone or prednisolone. All uses require testing for specific genetic mutations using an FDA-approved companion diagnostic before starting treatment.

Most-Reported Side Effects for Olaparib

From FAERS, the FDA’s public side-effect reporting system (20,798 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Malignant neoplasm progression 2,063 reports
Nausea 1,827 reports
Fatigue 1,762 reports
Anemia 1,622 reports
Vomiting 724 reports
