Heart Health & Cholesterol Supplements

Omega-3 Fish Oil

Omega-3 fatty acids (EPA and DHA) are among the most studied supplements in existence, with strong evidence for cardiovascular support.

• EPA + DHA combined (2-4g/day): Reduces triglycerides by 15-30%. The REDUCE-IT trial showed high-dose EPA (Vascepa, 4g/day) reduced cardiovascular events by 25%.
• Form matters: Triglyceride form absorbs better than ethyl ester form. Look for rTG (re-esterified triglyceride) on the label.
• Quality markers: IFOS 5-star certified, total oxidation value (TOTOX) < 26, and specific EPA/DHA amounts listed (not just "fish oil 1000mg").

Watch for: Many cheap fish oils list 1000mg fish oil but only deliver 300mg EPA+DHA. Read the supplement facts panel, not the front label.

CoQ10 for Cardiovascular Health

CoQ10 is critical for mitochondrial energy production in the heart — the most energy-demanding organ in the body.

• Statin users: Statins inhibit the same pathway that produces CoQ10. Supplementation (100-200mg ubiquinol) may reduce statin-associated muscle pain, though trials are mixed.
• Heart failure: The Q-SYMBIO trial showed 100mg CoQ10 3x/day reduced cardiovascular mortality by 43% in heart failure patients over 2 years. Significant result from a well-designed trial.
• Blood pressure: Meta-analyses show modest blood pressure reductions (11/7 mmHg) with CoQ10 supplementation.

Plant Sterols & Policosanol

Plant sterols are structurally similar to cholesterol and compete for absorption in the gut, reducing LDL cholesterol.

• Plant Sterols (2g/day): Consistently reduce LDL cholesterol by 6-15%. This dose is achievable through fortified foods or supplements. FDA allows a qualified health claim for heart disease risk reduction.
• Policosanol (10-20mg/day): Derived from sugar cane wax. Cuban studies showed impressive cholesterol reduction, but independent studies outside Cuba have been inconsistent. Currently rated as having mixed evidence.

Magnesium for Heart Rhythm

Magnesium is involved in over 600 enzymatic reactions, including electrical signaling in the heart.

• Magnesium Glycinate (300-400mg/day): Well-absorbed, less GI distress. Supports heart rhythm stability and blood pressure regulation.
• Magnesium Taurate: Combines magnesium with taurine — both independently support cardiovascular function. Emerging evidence for this specific form in cardiac health.

Note: Up to 50% of Americans are estimated to have suboptimal magnesium intake. It's one of the most common nutrient shortfalls and one of the easiest to correct.
