Quick answer: Heart disease is driven by more than cholesterol. Chronic inflammation in artery walls, oxidized lipids, stiff blood vessels with low nitric oxide, insulin resistance and high blood pressure all play a role. Daily movement, a Mediterranean-style diet, steady blood sugar, good sleep and stress management are the foundation, and nutrients such as omega-3s, magnesium, CoQ10 and garlic can add support.
Key takeaways
Heart health depends on more than cholesterol, with artery-wall inflammation, oxidized lipids, stiff vessels and insulin resistance all playing a role.
Daily movement, a Mediterranean-style diet, steady blood sugar, good sleep and stress care form the foundation.
Omega-3s, magnesium, CoQ10 and garlic are nutrients commonly used for added support.
The root drivers of heart disease
The root drivers include chronic inflammation inside artery walls, oxidized LDL particles that injure the vessel lining, and low nitric oxide, which keeps blood vessels stiff. Insulin resistance and high blood sugar, high blood pressure, smoking and chronic stress also contribute.
Advanced lipid and inflammation markers can add detail beyond a standard cholesterol panel (see lipids explained and hs-CRP).
Daily habits that protect your heart
Aim for at least 150 minutes of moderate activity each week, and eat olive oil, berries, leafy greens, beans, nuts and fatty fish. Keep blood sugar steady, sleep seven to nine hours, manage stress, and do not smoke.
Nutrients commonly used for heart health
Omega-3s (EPA and DHA) lower triglycerides and calm inflammation (see who should consider omega-3s). Magnesium supports healthy blood pressure and heart rhythm, CoQ10 fuels heart muscle cells and is often considered with statins, and vitamin K2 helps keep calcium out of arteries.
Garlic has been studied for blood pressure and cholesterol, and pomegranate supports nitric oxide and protects LDL from oxidation. Hawthorn is a traditional heart herb that can interact with heart medications, and nattokinase is an enzyme studied for blood flow that can increase bleeding risk.
Your heart and healthy aging
Blood vessels age along with the rest of the body: chronic inflammation, oxidative damage and stiffening reduce oxygen and nutrient delivery to every tissue, and heart muscle depends on healthy mitochondria. Protecting your cardiovascular system protects your brain, kidneys and energy as you age. Related: myocardial stress markers.
Safety
Many heart-supporting supplements affect bleeding, blood pressure or heart rhythm. Talk with your provider before starting them if you take blood thinners, blood pressure medication or heart rhythm medication, and never stop a prescribed heart medication on your own.
When to see a naturopathic doctor
It may be time to see a naturopathic doctor if you have high blood pressure, high cholesterol or a family history of heart disease, or if you want to understand your cardiovascular risk beyond cholesterol. The same is true if you take heart medications and want to add natural support safely, or if you want a prevention plan built around your labs and lifestyle.
See a medical provider promptly or call 911 for chest pain or pressure, pain spreading to the arm, jaw or back, shortness of breath, fainting, or sudden weakness or trouble speaking.
What the research shows
Diet pattern has the strongest evidence. In PREDIMED, 7,447 Spanish adults at high heart risk followed a Mediterranean diet with extra olive oil or nuts, or a low-fat control diet, for about 4.8 years. Major heart events occurred in 3.8% and 3.4% of the Mediterranean groups compared with 4.4% of controls, about a 30% lower relative risk. The original report was withdrawn over randomization problems and reanalyzed in 2018, an important caveat.
Plant sterols lower LDL cholesterol. A 2014 meta-analysis by Ras and colleagues of 124 studies found that 0.6 to 3.3 grams a day lowered LDL by about 6% to 12%. These studies measured cholesterol rather than heart events.
Omega-3 results depend on dose and form. In REDUCE-IT, 8,179 high-risk adults on statins with elevated triglycerides took 4 grams a day of purified prescription EPA or placebo for about 4.9 years, and heart events fell from 22.0% to 17.2%. That was a prescription product in high-risk patients, and it also increased atrial fibrillation, so it should not be generalized to over-the-counter fish oil.

Frequently asked questions
What causes heart disease besides cholesterol?
Inflammation, high blood pressure, insulin resistance, smoking, oxidized lipids and stress all contribute.
Which supplements are good for heart health?
Omega-3s, magnesium, CoQ10 and garlic have the most research. Choice depends on your labs and medications.
Is fish oil good for the heart?
Omega-3s lower triglycerides. Benefits for other heart outcomes vary, and higher amounts may affect bleeding and heart rhythm.
Can supplements replace blood pressure medication?
No. They may help alongside lifestyle changes, but medication decisions belong with your prescriber.
