Is There a Natural Alternative to Lisinopril? An Honest Look at What Works
Quick Answer
No. There is no natural alternative to lisinopril that reproduces what the medication does at prescription strength, and stopping it on your own can make blood pressure rebound higher than before. If a dry cough is what brought you here, the fix is a doctor-directed switch to a different drug class, not a supplement. Lifestyle changes and a few botanical ingredients offer modest support alongside your prescription, never in place of it.
The rest of this page explains why the cough happens, what your doctor can switch you to, and exactly how much the most-compared supplement ingredients actually move blood pressure, with the studies attached.
What lisinopril actually does
Lisinopril belongs to a class of medications called ACE inhibitors (angiotensin-converting enzyme inhibitors) and it's one of the most commonly prescribed blood pressure medications in the United States. It works by blocking the enzyme that converts angiotensin I into angiotensin II, a hormone that narrows blood vessels. Less angiotensin II means blood vessels relax and widen, which lowers blood pressure and reduces the workload on the heart.
That mechanism has been studied in large clinical trials for decades. It's effective, well-understood, and inexpensive as a generic. None of that changes just because someone is looking for something different, but it's worth naming clearly before talking about alternatives, because "natural alternative" searches often come from frustration with a side effect, not from the medication failing to work.
Why people look for alternatives, and it's usually one thing
Read enough of these searches and the pattern is hard to miss: the reason is almost always the same, a persistent, dry, tickling cough that will not go away. This is a recognized class effect of ACE inhibitors, and the size of it has been measured. A 2023 network meta-analysis in the Journal of Clinical Hypertension pooled 135 randomized trials covering 45,420 patients and found people taking an ACE inhibitor were 2.21 times more likely to develop a cough than people taking placebo. Lisinopril specifically carried 4.39 times the risk of placebo. The cough is not dangerous on its own, but it is genuinely disruptive, and it sends people looking for a way around the medication entirely rather than around the actual problem.
Other, less common reasons include elevated potassium levels, dizziness, or simply wanting to take fewer medications overall, particularly after significant lifestyle improvements. Each of these has a different, specific answer, which is exactly why "natural alternative" as a general search doesn't lead anywhere useful. The real question is usually more specific than it first appears.
Why you should never just stop taking it
Whatever the reason for wanting a change, the path there runs through your doctor, not around them. That's true whether the goal is switching medications, adding lifestyle support, or eventually reducing dosage after sustained improvement.
What is the best alternative to lisinopril for the cough?
Short answer: an ARB, such as losartan or valsartan, prescribed by your doctor. ARBs control blood pressure through the same pathway but do not interfere with bradykinin, which is what causes the cough. In the same 45,420-patient analysis, people on an ACE inhibitor were 3.2 times more likely to cough than people on an ARB. No supplement addresses this mechanism.
Since the cough is the single biggest driver of "alternative to lisinopril" searches, it deserves a direct, useful answer rather than a vague one. The cough happens because ACE inhibitors, in addition to blocking angiotensin II, also interfere with the breakdown of a substance called bradykinin. When bradykinin builds up, particularly in the lungs, it can trigger that characteristic dry, tickling cough in susceptible people.
No supplement addresses that mechanism. What actually resolves the cough for most people is a doctor-directed switch to a different medication class: ARBs (angiotensin receptor blockers), such as losartan or valsartan. ARBs work at a different point in the same overall pathway, achieve similar blood pressure control, and (because they don't affect bradykinin the same way) generally don't cause the cough.
Lifestyle changes that support the same goal
Separate from the cough question, if the broader goal is supporting healthy blood pressure, whether to potentially reduce medication needs over time (with your doctor) or simply to give your treatment plan the best possible foundation, the lifestyle evidence is genuinely strong:
- A DASH-style eating pattern. In the original DASH trial, published in the New England Journal of Medicine, participants who already had high blood pressure dropped 11.4 mmHg systolic and 5.5 mmHg diastolic on the diet alone.
- Cutting sodium. The American Heart Association puts the ceiling at 2,300 mg a day and the ideal at 1,500 mg for most adults with high blood pressure.
- Regular aerobic exercise. Consistent, measurable effect across decades of trials, and it compounds with the diet changes rather than competing with them.
- Weight loss, when it applies. One of the few changes that can eventually alter what your doctor prescribes, though that call is theirs and it is based on readings over months, not weeks.
- Limiting alcohol.
For the full breakdown of each of these, our guide on supporting healthy blood pressure without medication covers the details and how to make them stick.
Are there natural ACE inhibitors?
Short answer: some foods and botanicals show mild ACE-inhibiting activity in laboratory work, hibiscus being the most studied, but none of them inhibit the enzyme at anything close to the strength of a prescription ACE inhibitor. "Natural ACE inhibitor" describes a mechanism seen in a test tube, not a treatment that replaces lisinopril in a person.
The phrase turns up a lot in supplement marketing, and it is worth separating what the research actually shows from what the label implies. A compound can bind the same enzyme and still produce a fraction of the effect at the doses a human can realistically take. That is the gap between the two meanings, and it is where most of the confusion lives.
Supplement ingredients most often compared to ACE inhibitors
A few supplement ingredients get compared to ACE inhibitors specifically because their proposed mechanisms overlap, at least partially, with how lisinopril works. Here is what the pooled research actually found for each, with the studies linked:
| Ingredient | Why it's compared to ACE inhibitors | Typical effect |
|---|---|---|
| Hibiscus | Mild ACE-inhibitor-like activity from its anthocyanin compounds, the closest mechanism match on this list | 7.10 mmHg systolic in a systematic review and meta-analysis, a fraction of what lisinopril does |
| Aged garlic extract | Supports nitric oxide production, a different but complementary pathway to vessel relaxation | The honest answer is that the trials disagree. Pooled estimates run from about 2.5 mmHg to 8.12 mmHg systolic depending on which meta-analysis you read |
| Dietary nitrates (beetroot) | Directly supports nitric oxide, producing a relatively fast vessel-relaxing effect | Around 5 mmHg systolic in a 2024 meta-analysis, and it acts within hours rather than weeks |
Even added together, these effects don't approach what lisinopril achieves. The honest way to think about them is as complementary support discussed with your doctor, not a substitute.

Exploring Supplement Support Alongside Your Treatment Plan?
Two of the three ingredients above, hibiscus and garlic, show up together in multi-botanical formulas sold for blood pressure support. We took one of the most advertised ones apart ingredient by ingredient, including what its label does not tell you about doses.
Read Our Independent ReviewWhat a realistic conversation with your doctor looks like
Whatever's driving the search for an alternative, the most productive next step is usually a specific, well-prepared conversation rather than a switch you make on your own. That conversation tends to go better with concrete information rather than a general complaint:
- Name the specific issue: cough, dizziness, a lab result, or simply wanting to explore reducing medication over time
- If it's the cough, ask directly about switching to an ARB such as losartan
- Bring a home blood pressure log if you're asking about reducing dosage
- Ask specifically whether any supplement you're considering is safe alongside your current prescription
- Never adjust the dose or stop taking it based on how you feel in the moment
Frequently asked questions
Is there a natural alternative to lisinopril?
No supplement or lifestyle change reproduces exactly what lisinopril does at prescription strength. Some lifestyle changes and supplement ingredients have modest, real evidence for supporting blood pressure, but they are not a substitute for lisinopril in someone who has been prescribed it, and stopping it without medical guidance can be dangerous.
Can I just stop taking lisinopril and switch to supplements?
No. Stopping lisinopril abruptly can cause blood pressure to rebound, sometimes significantly, and doing so without medical supervision removes a treatment with proven, well-established effectiveness. Any change to a prescribed medication should go through your doctor, not be self-directed.
Why do people want to stop taking lisinopril?
The most common reason is a persistent dry cough. In a 2023 analysis of 135 randomized trials, lisinopril carried 4.39 times the cough risk of placebo. Other reasons include elevated potassium, dizziness, or simply wanting to take fewer medications, particularly when lifestyle changes have improved blood pressure significantly.
Why does lisinopril cause a dry cough?
Lisinopril, like other ACE inhibitors, blocks an enzyme that also breaks down a substance called bradykinin. When bradykinin builds up in the lungs, it can trigger a persistent, dry, tickling cough in some people. This is a known class effect of ACE inhibitors, not a sign of doing something wrong.
What do doctors usually do about the lisinopril cough?
The typical solution is switching to a different medication class called an ARB (angiotensin receptor blocker), such as losartan, which works similarly but doesn't affect bradykinin and generally doesn't cause the cough. This is a medication change your doctor makes, not something to address with a supplement.
Which supplements are most often compared to ACE inhibitors like lisinopril?
Hibiscus is the most frequently studied, with some research showing mild ACE-inhibitor-like activity, though far weaker than the medication. Aged garlic extract and dietary nitrates from beetroot are also commonly discussed, with modest evidence for each.
Are there natural ACE inhibitors?
Some foods and botanicals, hibiscus most of all, show mild ACE-inhibiting activity in laboratory studies. None of them inhibit the enzyme anywhere near the strength of a prescription ACE inhibitor at doses a person can realistically take, so the phrase describes a mechanism rather than a replacement for lisinopril.
Are there alternatives to lisinopril with fewer side effects?
There are several other blood pressure medication classes, and which one fits depends on your readings, your kidney function, and what else you take, so it is a decision for your doctor. For the dry cough specifically, the usual switch is to an ARB, which controls blood pressure through the same pathway without the bradykinin buildup that causes the cough.
Can lifestyle changes eventually replace lisinopril?
For some people with well-controlled blood pressure who make significant, sustained lifestyle changes, a doctor may eventually reduce or stop medication. This is a decision made gradually and medically, based on consistent readings over time, never something to decide and act on alone.
