The bottom line No known interaction

We found no known interaction between Functional Foods and Lisinopril 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.

Functional Foods and Lisinopril

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 Lisinopril and Functional Foods 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.

Worth understanding: our licensed dataset holds no drug-interaction record for Functional Foods at all — not against Lisinopril, 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.

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.

Functional Foods safety at a glance

Functional Foods overall Generally safe Most functional foods are safe when eaten in normal food amounts as part of a balanced diet.

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

What Lisinopril’s Own FDA Label Lists

This is not an interaction — none of it involves Functional Foods. These are the most notable effects listed in the ADVERSE REACTIONS section of Lisinopril’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. 10 of them are worth acting on rather than waiting out — marked below.

  • A stroke or mini-stroke Worth acting on
  • Pain or burning when passing urine Worth acting on
  • Memory problems Worth acting on
  • Dehydration Worth acting on
  • High potassium Worth acting on
  • Low sodium Worth acting on
  • Unsteadiness Worth acting on
  • Low blood sugar Worth acting on
  • A slow heartbeat Worth acting on
  • A heart attack Worth acting on

Showing the 10 most notable of 79 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 Lisinopril. Read the label on DailyMed › Where a percentage is shown, it is the share of 313,746 voluntary FDA FAERS reports for Lisinopril that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Functional Foods’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Functional Foods side to compare — that is a limit of the record, not a statement that Functional Foods has no side effects.

Where does our data come from?
  • Source: the Natural Medicines (TRC Healthcare) clinical database — the evidence-graded professional reference for herb & supplement interactions. Functional Foods is not yet covered by that licensed database, so its write-up cites publicly available medical sources directly (see the references below).
  • Citation library: 103,510 references behind our interaction content, 65,311 of them resolved to verified PubMed/DOI sources. See every Functional Foods reference on this page ↓
  • Freshness: we automatically re-check this combination every week — this pair was last verified September 13, 2026. The Functional Foods and Lisinopril records this page draws on were last updated June 20, 2026.
  • What “no known interaction” means: no documented interaction in the sources above — not a guarantee of safety. Supplements are studied far less than prescription drugs, so we say exactly what the evidence supports, and nothing more.

About Functional Foods

What is Functional Foods?

  • Heart and cholesterol health
  • Digestive and gut health
  • Bone health
  • Immune support
  • General nutrition and wellness

Functional foods are everyday foods or drinks that have been enriched, fortified, or contain natural components thought to offer health benefits beyond basic nutrition. Some, like probiotic yogurts or plant-sterol spreads, have reasonable supporting evidence, while many marketed claims are weak or unproven. They are best seen as part of a balanced diet, not a replacement for medicine or a healthy lifestyle.

Fortified foods, enriched dairy, probiotic yogurts, fortified cereals, functional beverages, bars

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

Functional Foods: dosing

There is no single dose for "functional foods" because the category is so broad. The right amount depends on the specific product and the active ingredient it contains.The best approach is to follow the serving size on the product label and not exceed it without advice. For ingredients like plant sterols or fiber, the package often lists how much to eat to get the claimed benefit.Avoid combining many fortified products at once, since added nutrients can add up.

About Lisinopril

What Is Lisinopril Used For?

Brand names: Zestril, Prinivil, Qbrelis

Lisinopril treats high blood pressure (hypertension) in adults and children 6 years and older, and can be used alone or alongside other blood pressure medicines. Lowering blood pressure reduces the risk of strokes and heart attacks. The tablet combination product containing lisinopril and hydrochlorothiazide is specifically indicated for high blood pressure.

Lisinopril is also used as an add-on therapy to reduce signs and symptoms of systolic heart failure, and to reduce the risk of death in people who are hemodynamically stable (have reasonably stable circulation) within 24 hours of an acute heart attack (acute myocardial infarction).

Most-Reported Side Effects for Lisinopril

From FAERS, the FDA’s public side-effect reporting system (313,746 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Fatigue 20,515 reports
Nausea 19,130 reports
Diarrhea 17,858 reports
Dyspnea 14,363 reports
Dizziness 13,969 reports
