Quick Answer

What are the best supplements for heart health?

The top 3 evidence-based supplements for heart health are Omega-3 (EPA/DHA) (8.5/10), CoQ10 (8/10), and Magnesium (8/10). Reduces triglycerides 15-30%, lowers inflammation

**Heart disease is the #1 killer, but most "heart health" supplements are marketing.** A few have genuine evidence from cardiology research. Omega-3s at prescription doses reduce cardiovascular events by 25%. Here's what's actually worth taking.

Strong Evidence

Effective Dose2-4g EPA/DHA daily for therapeutic effect
Time to Effect4-8 weeks for lipid changes

The REDUCE-IT trial showed high-dose EPA (4g Vascepa) reduced cardiovascular events by 25% in high-risk patients. Omega-3s lower triglycerides by 15-30%, reduce inflammation, and may stabilize arterial plaques.

Best for:High triglyceridesPost-heart attackFamily history of heart diseaseChronic inflammation
Effective Dose100-300mg daily
Time to Effect4-12 weeks

CoQ10 is essential for cellular energy production in the heart. The Q-SYMBIO trial showed it reduced major cardiac events by 43% in heart failure patients. Statins deplete CoQ10, making supplementation particularly important.

Best for:Statin usersHeart failureAge 50+Fatigue with heart issues
Effective Dose300-400mg daily
Time to Effect2-4 weeks

Magnesium regulates heart rhythm and blood pressure. A meta-analysis found it reduces blood pressure by 2-3 mmHg systolic. Deficiency is linked to arrhythmias, hypertension, and increased cardiac risk.

Best for:High blood pressureHeart palpitationsMuscle crampsDiuretic users

Moderate Evidence

Effective Dose100-200mcg daily
Time to Effect6-12 months for arterial effects

K2 directs calcium to bones instead of arteries. The Rotterdam Study found those with highest K2 intake had 52% lower arterial calcification. Works best with D3.

Best for:High calcium intakeVitamin D supplementersArterial calcification concerns
Effective Dose600-1,200mg aged garlic extract
Time to Effect8-12 weeks

Aged garlic extract (Kyolic) has shown modest blood pressure reduction (5-8 mmHg) in meta-analyses. Less effective than medication but may help alongside lifestyle changes.

Best for:Borderline high blood pressureThose avoiding medication

Beyond Supplements

  • Diet (Mediterranean) trumps any supplement for heart health
  • Exercise is more powerful than pills. 150 min/week minimum.
  • Sleep apnea is a major cardiac risk factor. Get tested if you snore.
  • Manage stress. Chronic stress directly damages blood vessels.

Note: Heart disease is serious. Supplements don't replace medication or lifestyle changes. Work with a cardiologist for personalized recommendations.
