Let's be honest. We’ve all seen those sketchy ads at the bottom of a news site. You know the ones—usually featuring a picture of a clogged pipe or some "miracle" fruit—claiming they can "scrub" your blood vessels clean overnight. It sounds great. It sounds simple. It’s also mostly a lie.
If you’re asking can you clean your arteries, you’re likely worried about plaque. Specifically, atherosclerosis. This is the slow, silent buildup of fats, cholesterol, and other substances in and on your artery walls. Think of it like old plumbing, but instead of hair and soap scum, it’s oxidized LDL cholesterol and calcium. It’s tough. It’s stubborn. And once it’s stuck there, it doesn't just wash away with a green juice or a handful of supplements.
But here is the nuanced truth: while you can't literally "drain-clean" your arteries, you can absolutely stabilize what’s there and potentially shrink the fatty core of those blockages. It’s less like using a pipe cleaner and more like changing the chemistry of the sludge so it stops growing and hardens into a scar rather than a ticking time bomb.
The plumbing myth vs. biological reality
People think of arteries like PVC pipes. If a pipe is clogged, you pour something down it to dissolve the grease, right?
Biological systems are messier. Plaque doesn't just sit on top of the artery wall; it actually gets inside the lining (the endothelium). It’s buried. When we talk about whether can you clean your arteries, we have to talk about the difference between "soft" plaque and "hard" plaque.
Soft plaque is the dangerous stuff. It’s a soup of lipids that can rupture, causing a blood clot and, ultimately, a heart attack. Hard plaque is calcified. It’s basically bone inside your vessels. You aren't "cleaning" bone away without surgery. However, modern medicine—and some pretty aggressive lifestyle shifts—can pull the liquid fats out of the soft plaques. This makes them smaller and much less likely to burst.
Dr. Peter Attia, a prominent physician focused on longevity, often discusses the "ApoB" protein. This is the real villain. It’s the delivery truck that drops the "trash" into your artery walls. If you stop the trucks, the cleanup crew (your HDL particles, though it’s more complex than just "good" cholesterol) can actually start to do some minor repairs.
Can you clean your arteries with diet alone?
You’ll hear people swear by the Dean Ornish program or the Esselstyn diet. These are ultra-low-fat, plant-based protocols. Do they work?

Well, Caldwell Esselstyn’s research at the Cleveland Clinic showed some pretty dramatic results. He took patients with severe heart disease and put them on a diet so strict it makes a standard vegan diet look like a buffet at a steakhouse. No oil. No nuts. No meat. No dairy. In some of these patients, follow-up angiograms actually showed a slight "widening" of the artery lumen.
It wasn't a total "cleaning," but it was regression.
The mechanism here is fascinating. When you stop flooding your system with saturated fats and refined sugars, your endothelial function improves almost immediately. Your arteries become more "stretchy." They produce more nitric oxide. This gas helps the vessels relax and prevents more gunk from sticking to the walls.
But let's be real. Most people can't live on steamed kale and brown rice forever.
The Mediterranean approach
The PREDIMED study is the gold standard here. It didn't focus on "cleaning" so much as "preventing the explosion." By eating high-quality fats like extra virgin olive oil and nuts, participants saw a massive drop in cardiovascular events. They didn't necessarily have "cleaner" pipes, but they had "stronger" pipes.
If you want to move the needle, you need to focus on:
- Soluble fiber: This is the stuff in oats, beans, and lentils. It acts like a sponge in your digestive tract, soaking up cholesterol before it even reaches your bloodstream.
- Omega-3s: Think fatty fish like sardines or salmon. They reduce inflammation. Inflammation is the "glue" that makes plaque stick.
- Phytosterols: Found in unrefined plant foods, these compete with cholesterol for absorption.
The role of statins and the new "scouring" drugs
Diet is the foundation, but for many, it's not enough. Genetics plays a huge, often unfair role. You might eat like a monk and still have high levels of Lp(a)—a specific type of cholesterol that is basically "sticky" and genetic.

This is where the medical answer to can you clean your arteries gets interesting. Statins are the old school. They lower the LDL (the bad stuff), which slows down the buildup. But the new kids on the block, like PCSK9 inhibitors (Repatha or Praluent), are game changers.
These drugs are like putting your LDL-clearing system on steroids. Some studies, like the GLAGOV trial, used IV ultrasound to look inside arteries. They found that when LDL was pushed to ultra-low levels (below 30 mg/dL), a significant percentage of patients saw an actual reduction in plaque volume.
The plaque shrunk.
Is it "clean"? No. But it is "less blocked."
We are also seeing incredible data with SGLT2 inhibitors and GLP-1 agonists (like Ozempic or Wegovy). While these started as diabetes and weight-loss drugs, they seem to have a protective effect on the heart that goes beyond just losing weight. They reduce the systemic inflammation that makes plaque so volatile.
Why exercise is the closest thing to a "scrub"
If you want to actually "flush" the system, you need to sweat. Not because sweat cleans arteries, but because of shear stress.
When your heart rate goes up, your blood flows faster. This creates a friction called "laminar shear stress" against the artery walls. This friction signals the endothelial cells to produce more nitric oxide and repair enzymes. It’s like a workout for the inside of your vessels.

High-intensity interval training (HIIT) has been shown to be particularly effective at improving endothelial function. It’s basically forcing the artery to expand and contract, keeping it supple. A stiff artery is an artery that collects plaque. A flexible one is much more resilient.
The "miracle" supplements: Fact vs. Fiction
Let's debunk some stuff.
- Chelation therapy: Some people claim getting IV drips of EDTA can "strip" calcium out of your arteries. The TACT study showed a very modest benefit, specifically in diabetics, but it is far from a "cleaning" solution. It’s also risky.
- Vitamin K2: There is some evidence that K2 helps direct calcium out of the soft tissues (like arteries) and into the bones. It’s a great supplement for general health, but it won't clear a 70% blockage.
- Garlic extract: Aged garlic extract has been shown in some small trials (like those by Dr. Matthew Budoff) to slow the progression of coronary calcification. It's a "maybe" in the "yes" column for slowing things down.
What you should actually do right now
If you are worried about your arteries, stop guessing. A "standard" cholesterol test is a 1970s tool. You need a 2026 approach.
First, get a Calcium Score (CAC). It’s a quick CT scan. It tells you exactly how much "hard" plaque you have. If your score is zero, great. If it’s high, you know you’re already in the red zone.
Second, ask for an ApoB test. This is a more accurate measure of your heart risk than standard LDL. If your ApoB is high, your arteries are actively "getting dirty."
Actionable Roadmap:
- Kill the sugar: High blood sugar creates "advanced glycation end-products" (AGEs). These literally "caramelize" your artery walls, making them brittle and sticky.
- Manage blood pressure: Think of high BP like a power washer on a high setting hitting a delicate surface. It causes micro-tears that the body "patches" with plaque. Keep it under 120/80.
- Fiber up: Aim for 30–50 grams a day. It’s the closest thing to a manual broom for your metabolic system.
- Don't ignore the basics: Smoking is essentially like pouring acid into your bloodstream. It destroys the endothelium instantly.
The bottom line? You can't undo twenty years of bacon cheeseburgers and smoking in a weekend. But you can change the environment of your blood so that plaque stops growing, stabilizes, and in some cases, slightly regresses. It's about biology, not plumbing.
Focus on making your plaque "quiet" and "stable." A stable 30% blockage will never hurt you. A "vulnerable" 20% blockage can kill you tomorrow. The goal isn't a perfectly pink, empty tube—it's a resilient, non-inflamed system that stays open for a hundred years.
