Evidence-Based Stack
Cardiovascular Stack
Four compounds with large-trial evidence on heart disease endpoints — not biomarker-only pixie dust.
Cardiovascular supplement marketing is rife with biomarker theater: compounds that move a lab number without affecting actual events (heart attacks, strokes, death). This stack includes only compounds with outcome-level evidence. Omega-3 at therapeutic doses has cardiovascular benefit in meta-analyses; CoQ10 has Q-SYMBIO-level evidence in heart failure; Vitamin K2 addresses arterial calcification; Magnesium has hard event evidence in large cohorts. Niacin, red yeast rice, and garlic are omitted — they move biomarkers but have mixed outcome data.
What's in it
High-dose EPA (REDUCE-IT trial, Vascepa) meaningfully reduces cardiovascular events. General fish-oil doses show smaller but real benefit.
Dose: 2,000–4,000 mg combined EPA+DHA/day with food. Higher if triglycerides are elevated.
Full Omega-3 Fatty Acids profile →Heart failure adjunct with Q-SYMBIO-level RCT evidence. Also addresses statin-induced muscle fatigue.
Dose: 100–300 mg/day (ubiquinol preferred over 50) with fat.
Full CoQ10 (Ubiquinone/Ubiquinol) profile →Redirects calcium from arterial walls to bones — reduces arterial stiffness in trials. Pairs with vitamin D.
Dose: 90–180 mcg MK-7/day with a fat-containing meal.
Full Vitamin K2 profile →Meta-analyses consistently show magnesium supplementation reduces blood pressure and atrial fibrillation risk.
Dose: 300–400 mg elemental/day (glycinate or citrate form).
Full Magnesium profile →How to take it
Omega-3 daily with fish meals or a quality IFOS-certified supplement. CoQ10 is particularly valuable if you're on a statin (mitigates muscle fatigue). K2 + vitamin D as a pair for long-term arterial health. Magnesium for BP support and general cardiovascular function. Monitor triglycerides and BP every 6 months to track effect.
Cautions
Vitamin K2 interacts meaningfully with warfarin — contraindicated if on it. High-dose omega-3 has mild anticoagulant effect; watch with blood thinners. CoQ10 modestly reduces warfarin's effect (structural similarity to vitamin K). Magnesium can accumulate in kidney disease — dose-adjust if GFR is impaired. Coordinate with your cardiologist if on multiple cardiovascular medications.
