Natural Alternatives to Lisinopril: What Actually Helps
Quick Answer
There's no supplement or lifestyle change that reproduces what lisinopril does at prescription strength, and stopping it on your own can cause blood pressure to rebound. Most people searching for a "natural alternative" are actually dealing with a specific, well-known side effect: the dry cough that affects roughly 1 in 10 people on ACE inhibitors. The real-world fix for that is usually a doctor-directed switch to a different medication class, not a supplement. That said, evidence-backed lifestyle changes and a handful of supplement ingredients can offer modest support alongside your prescribed treatment, with your doctor's knowledge.
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
In my experience, when a patient asked about getting off lisinopril specifically, the reason was almost always the same: a persistent, dry, tickling cough that wouldn't go away. This is a recognized class effect of ACE inhibitors, affecting roughly 1 in 10 people who take them. It's not dangerous on its own, but it's genuinely disruptive. Annoying enough that people start searching for a way around the medication entirely, rather than around the specific 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 actually fixes the cough (hint: it's not a supplement)
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, associated with reductions of roughly 8-14 mmHg systolic in research
- Reducing sodium intake, associated with roughly 5-6 mmHg
- Regular aerobic exercise, associated with roughly 4-9 mmHg
- Weight loss, when applicable, associated with roughly 5-20 mmHg per 20 lbs lost
- Limiting alcohol intake
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.
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:
| Ingredient | Why it's compared to ACE inhibitors | Typical effect |
|---|---|---|
| Hibiscus | Some studies show mild ACE-inhibitor-like activity from its anthocyanin compounds | Roughly 5-7 mmHg systolic, far below lisinopril's effect |
| Aged garlic extract | Supports nitric oxide production, a different but complementary pathway to vessel relaxation | Roughly 5-8 mmHg systolic |
| Dietary nitrates (beetroot) | Directly supports nitric oxide, producing a relatively fast vessel-relaxing effect | Roughly 4-5 mmHg systolic, often within hours |
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.

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, which affects roughly 1 in 10 people who take ACE inhibitors like lisinopril. Other reasons include elevated potassium, dizziness, or simply wanting to reduce the number of medications taken, particularly if 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.
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.
