6 Heart Supplements Ranked for Arterial Plaque Reduction & Heart Support

Millions of people take a heart supplement every morning. Fish oil. CoQ10. Magnesium. Garlic. We bought the six most-purchased and ranked them on one question most of us never think to ask: do they actually touch the thing that drives heart disease?

Most heart supplements work on a number, not the buildup. A triglyceride level, a blood-pressure reading, a cholesterol marker. Useful, but the arterial plaque most associated with heart disease keeps progressing underneath. Only one supplement on this list is studied for that buildup directly.

Supplement

What it mainly supports

Targets plaque?

Nattokinase (Evera Heart)

Fibrin / arterial buildup

Yes

Fish Oil / Omega-3

Triglycerides

No

CoQ10

Cellular energy

No

Magnesium

Rhythm / blood pressure

No

Garlic Extract

Blood pressure / lipids

No

Red Yeast Rice

Cholesterol

No

Ranking reflects how directly each supplement is studied for arterial plaque, the buildup most associated with heart disease. Supportive supplements still have a role — see each entry below.

The 3 Factors That Matter Most For Arterial Support

Title

Heart attacks and strokes are linked to more than 17 million deaths every year, and arterial plaque is the quiet driver behind them. It builds slowly: the artery wall gets irritated, cholesterol deposits, fibrin locks the buildup in place, and the channel your blood flows through narrows over time.

For a nattokinase formula to work, three things decide whether it can truly dissolve arterial plaque and support healthy heart function.

1) Dose. The most-cited human study, Chen 2022 (Frontiers in Cardiovascular Medicine, 1,062 participants, 12 months), found meaningful reductions in arterial plaque, blood pressure, and cholesterol at roughly 10,000 FU/day. At about 3,600 FU/day the benefit largely disappeared, yet most products on the shelf sit at 2,000.

 

2) Coating. Nattokinase is an enzyme that stomach acid degrades before it reaches the blood unless the capsule is enteric-coated. A big number on the label means nothing if the enzyme never survives the trip.

 

3) Co-factors. The supporting research rarely studies nattokinase in isolation. Compounds like CoQ10, bromelain, turmeric, ginger, olive leaf, and white willow bark are meant to work alongside it. A bare enzyme is doing half the job.

How it works

Nattokinase is a fermented-soy enzyme that acts on fibrin, the protein that locks arterial buildup in place. By supporting the breakdown of fibrin, it's studied for working on the buildup itself, not just a downstream number

In the most-cited human study (Chen 2022, 1,062 participants, 12 months), the clinical-dose group saw arterial plaque drop by roughly 36%, with LDL cholesterol down about 18% and blood pressure improved alongside it

That plaque reduction is the part that matters most for long-term risk

Research on plaque regression found that reducing arterial plaque by just 1% was associated with up to a 25% lower risk of a major adverse cardiovascular event, like a heart attack or stroke.

Source: Iatan et al., JAMA Cardiology 2023, meta-analysis of 7,400+ patients. Plaque-regression finding is general and not specific to nattokinase.
Title

The one catch

Title

It only works at the studied dose, roughly 10,000 FU per day. The lower-dose group in the research saw no significant change

Most nattokinase on the shelf is just 2,000 FU, about a fifth of that

Evera Heart is the rare formula built to the clinical-range dose, enteric-coated to survive stomach acid, and paired with six co-factors (CoQ10, bromelain, turmeric, ginger, olive leaf, white willow bark)

Why it ranked first
It's the only entry on this list studied for the arterial buildup itself rather than a downstream marker. The supporting ingredients fish oil and CoQ10 buyers are reaching for are already built into the formula, at a clinical-range dose, in one daily serving. For someone who wants their heart supplement aimed at the root cause instead of the edges, this is the one that fits.

2. Fish Oil / Omega-3

Ultimate Omega

best-in-class: Nordic Naturals

 8.0/10

B

Overall Rating
Title

What it supports

Title

The most popular heart supplement in America

Omega-3s (EPA and DHA) studied for supporting healthy triglyceride levels and a normal inflammatory response

A reasonable foundational choice for someone who doesn't eat much fish
Title

Where it falls short

Works on triglycerides and inflammation, not on arterial plaque

Major medical centers note that over-the-counter fish oil hasn't been shown to prevent heart events the way many shoppers assume

The active dose is far below prescription strength and sometimes below the label claim
Title

Verdict
Useful as a general-wellness foundation. But if the goal is the buildup inside the artery, fish oil isn't aimed there. Many people take it alongside something that is.

3. CoQ10

Ultra CoQ10

best-in-class: Qunol

 7.7/10

B−

Overall Rating
Title

What it supports

Title

An antioxidant the body uses for cellular energy, especially in the heart muscle

Levels decline with age, and it's commonly paired with other heart routines

Often recommended for people on certain medications that lower the body's own CoQ10
Title

Where it falls short

Supports energy production and acts as an antioxidant, but isn't studied for breaking down arterial buildup

Many fish-oil products toss in a token 30 mg, below the amount most CoQ10 research uses
Title

Verdict
A worthwhile co-factor, and one of the reasons a combined formula makes sense. On its own, though, it works on cellular energy, not the plaque itself.

4.  Magnesium

Magnesium Glycinate

best-in-class: Nature Made

  7.4/10

C+

Overall Rating
Title

What it supports

Title

The single most-used heart-friendly mineral

Studied for supporting normal heart rhythm and healthy blood pressure within a normal range

Many adults run low on it, so it's a sensible baseline
Title

Where it falls short

Its role is rhythm and blood-pressure support

It does not act on the arterial buildup that narrows the vessel over time

A good supporting player, not a root-cause one
Title

Verdict
Among the most justified supplements on this list for general support, but it operates on a completely different lever than plaque.

5.  Garlic Extract

Aged Garlic Extract

best-in-class: Kyolic

 7.0/10

C+

Overall Rating
Title

What it supports

Title

Aged garlic extract studied for supporting healthy blood pressure and lipid levels within a normal range

A long history of traditional use and a gentle, food-derived profile
Title

Where it falls short

The effects are modest and centered on blood pressure and cholesterol markers

It isn't positioned at the fibrin and buildup that lock plaque in place
Title

Verdict
A reasonable mild-support option, especially for blood pressure. But again, it works on a number, not on the buildup.

6. Red Yeast Rice

Red Yeast Rice

best-in-class: Nature's Bounty

6.2/10

C

Overall Rating
Title

What it supports

Title

Contains naturally occurring compounds studied for supporting healthy cholesterol levels

Popular with people specifically focused on their cholesterol number
Title

Where it falls short

Potency varies widely between brands, with inconsistent active-compound content batch to batch

Like the others, it targets a marker (cholesterol) rather than the arterial buildup itself

Worth discussing with a physician before use
Title

Verdict
Aimed squarely at the cholesterol number, with real batch-to-batch inconsistency. Not a root-cause option, and the one most worth running by a doctor first.

See the supplement built for the root cause, not just the markers.

The bottom line

Title

Most heart supplements aren't scams. They're just aimed at the wrong target. Fish oil tidies triglycerides. CoQ10 supports energy. Magnesium and garlic nudge blood pressure. Red yeast rice works on cholesterol. Each one manages a gauge on the dashboard.

But the buildup inside the artery wall — the plaque most associated with heart disease — keeps progressing underneath all of it. That's the difference worth understanding before you spend another month on a routine. The one supplement on this list studied for that buildup directly is nattokinase, and only at the clinical-range dose.

If you're going to take one thing for your heart, it's worth taking the one aimed at the cause. That's the one at the top of this list.
