Drug & supplement interaction

Macrobiotic Diet + Talazoparib

Talazoparib brand name: Talzenna.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 27, 2026
The bottom line No known interaction

We found no known interaction between Macrobiotic Diet and Talazoparib 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. Additionally, although there is no interaction, the two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.

Macrobiotic Diet and Talazoparib

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 Talazoparib and Macrobiotic Diet in our sources. This does not guarantee that the combination is completely free of risk — research on Macrobiotic Diet alongside specific medications may be limited.

Worth understanding: our licensed dataset holds no drug-interaction record for Macrobiotic Diet at all — not against Talazoparib, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.

Macrobiotic Diet is an eating pattern rather than something you take. Ask your pharmacist or doctor before changing how you eat while on a prescribed medicine: some medicines are dosed around meals, and a change in diet can change how they work. 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.

Macrobiotic Diet safety at a glance

Macrobiotic Diet overall Use caution Balanced versions can be healthy, but strict versions may cause nutrient deficiencies.
Pregnancy Use caution Strict versions may not provide enough protein, calories, or key nutrients; medical supervision is advised.
Breastfeeding Use caution Nursing parents need adequate calories and nutrients, so strict versions should be supervised by a clinician.

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

What to actually watch for

No Interaction Found — But Data Suggests Macrobiotic Diet and Talazoparib May Share a Side Effect

This is not an interaction. Neither one changes how your body handles the other, and nothing here says they react together. What our sources do show is that each has separately been linked to the effects below — so following Macrobiotic Diet while taking the medicine can make those effects more likely to turn up, and harder to pin on one or the other if they do. One of them is worth acting on rather than waiting out — marked below.

  • Bone thinning Worth acting on Additional detail

    Macrobiotic Diet

    “The macrobiotic diet has been associated with increased risk of rickets and osteoporosis, likely due to calcium and vitamin D deficiency. Following a strict macrobiotic diet that does not include additional intake of fish and fat has also been associated with reduced height for age in children less than 8-years-old.”

    Talazoparib

    Listed in the ADVERSE REACTIONS section of the FDA label for Talazoparib. Read the label on DailyMed ›

Effects for Talazoparib come from the ADVERSE REACTIONS section of its FDA label; effects for Macrobiotic Diet come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 1,699 voluntary FDA FAERS reports for Talazoparib that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

Overlapping uses

What Talazoparib Is Prescribed For, and What Macrobiotic Diet Has Been Studied For

These two come up together because they touch the same health topic — not because they do the same job. Talazoparib is a prescription medicine with approved uses on its FDA label. Macrobiotic Diet is an eating pattern: what follows is what researchers have looked at it for, and how strong that evidence is.

Talazoparib is prescribed for: Talzenna (talazoparib) is used as a single agent to treat adults with HER2-negative locally advanced or metastatic breast cancer who carry a germline BRCA mutation (an inherited change in a DNA-repair gene). Patients must be selected for this use based on an FDA-approved test. Talzenna is also used in combination with another medicine called enzalutamide to treat adults with metastatic castration-resistant prostate cancer (mCRPC — prostate cancer that has spread and no longer responds to standard hormone therapy) whose tumors have mutations in homologous recombination repair (HRR) genes involved in DNA repair.

Macrobiotic Diet has been studied for:

  • Cancer studied, not established Macrobiotic Diet has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

    Macrobiotic Diet for cancer

    Although there has been interest in using the macrobiotic diet for various cancers, including colon cancer, there is insufficient reliable information about the clinical effects of the macrobiotic diet for these conditions.

Effectiveness ratings and the research summaries above are the verbatim record from the Natural Medicines database, which grades evidence from “Effective” down to “Insufficient Reliable Evidence To Rate”. A rating below the top of that scale means researchers have looked at it — not that it works, and never that it can stand in for a prescribed medicine. Do not stop or replace Talazoparib on your own; if you are taking Macrobiotic Diet for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

From our pharmacist’s overview on the Talazoparib page

“Talazoparib (Talzenna) treats certain BRCA-mutated cancers, and with a drug doing that job I want its blood level exactly where the oncologist set it. The 54 supplements on this list mostly threaten that in one of two ways.”

About Macrobiotic Diet

What is Macrobiotic Diet?

  • General wellness and longevity
  • Cancer prevention and support (popular belief)
  • Heart health
  • Weight management
  • Digestive health

The macrobiotic diet is a plant-based eating pattern centered on whole grains, vegetables, and beans, with limited animal products and processed foods. Some versions can be healthy, but strict versions risk nutrient shortfalls, and there is no strong proof it treats or cures diseases like cancer. Talk to your doctor or a dietitian before starting, especially if you have a health condition.

Whole-food eating plan based on whole grains, vegetables, and legumes

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

Macrobiotic Diet: dosing

There is no standard dose for a diet. Instead, macrobiotic eating is about food choices and proportions, often with grains making up a large share of meals and vegetables and beans filling the rest.If you want to try this way of eating, choose a balanced version, include a variety of foods, and avoid the most restrictive forms. Many people on plant-based diets need a vitamin B12 supplement, and possibly vitamin D, calcium, iron, or omega-3s. A registered dietitian can help you plan meals and decide which supplements you may need.

Following Macrobiotic Diet While Taking Talazoparib: Common Questions

Is it safe to follow Macrobiotic Diet while taking Talazoparib?
We do not list a known interaction between Macrobiotic Diet and Talazoparib. That does not guarantee the combination is risk-free, so confirm with your pharmacist or doctor — especially if you take other medications or have a health condition.
Do Macrobiotic Diet and Talazoparib have any of the same side effects?
Yes — our sources link each of them separately to one of the same effects. That is not an interaction: neither changes how your body handles the other. It does mean that if one of those effects turns up, it can be harder to tell which one is behind it. They are listed on this page with the source behind each.
Are Macrobiotic Diet and Talazoparib used for the same thing?
They overlap in purpose, which usually means the real question is whether you need both rather than whether they are safe together. This page lists the shared uses and how strong the evidence is for Macrobiotic Diet in each. That is a conversation for your prescriber, especially if Talazoparib is being adjusted to a target.
Does Talazoparib interact with any supplements?
Yes. Talazoparib has documented interactions with 54 supplements in our database — Macrobiotic Diet is not one of them. The Talazoparib interaction page linked on this page lists every one, ranked by severity.
