About this protocol

Cardiovascular disease is the leading killer of adults globally. The supplement category for heart health is overrun with marketing, but a handful of compounds have legitimate long-term human evidence: omega-3 EPA/DHA, CoQ10, magnesium, vitamin K2, and taurine. None of these replace evidence-based pharmaceutical therapy (statins, ACE inhibitors, etc.) when one is medically indicated. They DO function well as a preventive baseline for adults without active cardiovascular disease, and as complements to medical therapy. This protocol is for cardiovascular maintenance and primary prevention — see Cholesterol Support or Blood Pressure Support for goal-specific protocols.

Where to start

Start with omega-3 EPA/DHA. Of all supplements, this has the most consistent long-term cardiovascular evidence — lower triglycerides, lower events in some trials, lower all-cause mortality.

Add CoQ10 (ubiquinol), especially if you''re on a statin or over 40. Statins deplete CoQ10; CoQ10 supplementation supports cardiac function and has small evidence for blood-pressure reduction.

Add magnesium glycinate for blood pressure, arrhythmia prevention, and metabolic support. Most adults under-consume magnesium.

Add vitamin K2 (MK-7) to direct dietary and supplemental calcium toward bones rather than arteries. Pair with vitamin D.

Add taurine for emerging cardiovascular and longevity evidence. The 2023 Science paper showing taurine slowing age-related decline in mice generated renewed interest, but human longevity evidence is still preliminary.

Get baseline labs: lipid panel + ApoB, hsCRP, fasting glucose, HbA1c, Lp(a) (once in a lifetime), and a coronary calcium score (CAC) at 40+. Lp(a) and CAC catch silent cardiovascular risk that other markers miss.

5 nutrients

Start here

Strongest evidence — the foundation of the stack.

Omega-3 (EPA/DHA)

2-4 g combined EPA+DHA daily, with breakfast
morningwith food

Omega-3 has the strongest long-term cardiovascular evidence of any supplement. Higher doses (2-4 g/day) of EPA-dominant formulations have stronger trial outcomes than lower doses. Triglyceride reduction is dose-dependent and substantial. REDUCE-IT trial showed 25% relative risk reduction in cardiovascular events with high-dose EPA.[1, 2, 3]

CoQ10 (Ubiquinol)

100-300 mg daily, with a fat-containing meal
morningwith food

CoQ10 is critical for cardiomyocyte energy production. Endogenous levels decline with age and are depleted by statins. Q-SYMBIO trial showed reduced cardiovascular mortality in heart failure with CoQ10. Particularly relevant for adults 40+ and statin users.[4, 5, 6]

Add if needed

Add these only if the foundation isn't enough.

Magnesium Glycinate

300-400 mg elemental, before bed
before bedempty stomach

Magnesium supports vascular smooth muscle relaxation, blood pressure, and arrhythmia prevention. Most adults under-consume magnesium. Observational studies link adequate magnesium intake with lower cardiovascular mortality.[7, 8]

Vitamin K2 (MK-7)

100-200 mcg daily, with vitamin D and food
morningwith food

Vitamin K2 activates matrix Gla protein, which inhibits arterial calcification. Observational studies (Rotterdam Study) link higher K2 intake with reduced coronary calcification and cardiovascular mortality. Critical pairing with vitamin D — D without K2 may shift calcium into arteries.[9, 10, 11]

Experimental

Emerging evidence — try last, only if curious.

Taurine

1-3 g daily, anytime
morningempty stomach

Taurine is a sulfur-containing amino acid concentrated in cardiac tissue. Trials in heart failure show improvements in left ventricular function. The 2023 Science paper on age-related taurine decline and longevity in animal models generated significant interest, though long-term human longevity evidence is still preliminary. Treat as the most speculative item.[12, 13, 14]

Warnings

Do not take with: Blood thinners (high-dose omega-3 has mild anti-platelet effect — discuss with your prescriber). Statins (CoQ10 complements, not interferes). Warfarin (vitamin K2 has theoretical interaction — discuss with prescriber). Antihypertensive medications (this stack can modestly lower BP — coordinate with prescriber).
Do not take if: You are on warfarin (discuss vitamin K2 with your prescriber — generally safe at low doses but stable intake matters). You have severe kidney disease (magnesium and taurine excretion impaired). You are pregnant or breastfeeding (lower priority for high-dose omega-3 and taurine — discuss). You have a clotting disorder. Consult your provider before starting if you have active cardiovascular disease — supplements complement medical therapy rather than replace it.

Lifestyle improvements

Exercise is the most-evidenced intervention

150-300 minutes of moderate aerobic exercise weekly plus 2-3 strength sessions reduces cardiovascular mortality by 30-50% across cohort studies. No supplement matches this.

Mediterranean dietary pattern

The most-evidenced diet for cardiovascular outcomes. Olive oil, fish, vegetables, fruit, nuts, whole grains, beans, moderate dairy, minimal red meat.

Sleep 7-9 hours

Short sleep is independently associated with cardiovascular events. Sleep apnea is a common, under-diagnosed cardiovascular risk factor — get tested if you snore, wake unrefreshed, or have witnessed apneas.

Body composition matters

Visceral fat drives cardiometabolic risk. A waist circumference under half your height is a reasonable target.

Don''t smoke

Smoking is the single largest reversible cardiovascular risk factor. Cessation at any age produces measurable risk reduction within 1-5 years.

Limit alcohol

The "moderate drinking is protective" framing has weakened in recent analyses. Less is better; intermittent is better than daily.

Get the labs that matter

ApoB (better than LDL-C), lipid panel, hsCRP, Lp(a) (once in a lifetime), HbA1c, fasting glucose, fasting insulin. CAC scan at 40+ if risk is uncertain.

Manage stress

Chronic stress drives sustained sympathetic activation and elevated BP. Breathwork, exercise, and addressing chronic stressors directly compound with the supplement foundation.
