Clinical guides, written and reviewed by Dr. Druz and our team.
Each guide covers the clinical evidence, correct dosing and form, drug interactions, and FAQs — so you can separate what works from what’s marketing.
Supplements Guides
Each guide covers the clinical evidence, correct dosing and form, drug interactions, and FAQs.
Nattokinase
Fibrinolytic enzyme for hypercoagulability and vascular plaque concerns. Evidence on CAC progression and blood viscosity.
Vitamin K2 + D3
Directs calcium into bones and away from arterial walls. Rotterdam Study linked high K2 intake to 57% lower cardiovascular mortality.
Aged Garlic Extract
Slows coronary artery calcium progression, lowers blood pressure, and provides antioxidant vascular protection.
CoQ10 (Ubiquinol)
Essential mitochondrial cofactor depleted by statins. Q-SYMBIO: 300 mg/day cut cardiovascular events 43% in heart failure.
Omega-3 EPA/DHA
Reduces triglycerides 25–45% at therapeutic doses. REDUCE-IT showed a 25% reduction in major cardiovascular events.
Berberine
Inhibits PCSK9 and activates AMPK, reducing LDL ~18 mg/dL and improving blood sugar. Ideal for metabolic syndrome.
Bergamot
The most potent natural LDL-lowering supplement: 30.6% LDL reduction, 37.9% triglyceride reduction, visceral fat reduction.
Magnesium
Cofactor in 300+ reactions. Up to 60% of Americans are insufficient. Glycinate and threonate for heart, sleep, BP.
Antioxidants (C/E)
Why high-dose vitamin E and beta-carotene failed cardiovascular trials — and what the evidence actually supports.
Nutrition Guides
Evidence-based guidance on foods, drinks, and dietary patterns that protect cardiovascular health.
Best Foods for Heart Health
The Mediterranean pattern, anti-inflammatory staples, what to avoid, and how to eat for your specific biomarkers.
Worst Foods for Your Heart
Ultra-processed foods, trans fats, added sugars, and processed meats — what the evidence says about each.
Best & Worst Drinks for Heart Health
Coffee, green tea, alcohol, sugary drinks — evidence on which beverages help or harm.
Symptoms Guides
A cardiologist’s framework for interpreting cardiovascular symptoms — when they matter and when to seek urgent care.
Heart Palpitations
Causes, natural remedies that actually work (magnesium, caffeine elimination, sleep), and the red flags that require urgent evaluation.
Chest Pain: What It Could Mean
Cardiac vs. non-cardiac causes, red flags for immediate action, and what a proper evaluation looks like.
When to Go to the ER vs. a Cardiologist
A practical decision framework for cardiovascular symptoms — what can wait and what cannot.
Cardiovascular Longevity Guides
The science of living to 100 with a strong heart — VO2 max, calcium scoring, CIMT, HRV, genomics.
Vascular Age
How to measure your true cardiovascular age with CAC scoring, CIMT, VO2 max, and advanced biomarkers — and how to lower it.
VO2 Max and Heart Health
Why VO2 max is the strongest predictor of cardiovascular longevity — and what interventions actually raise it.
Coronary Calcium Score
The single most powerful predictor of future cardiac events — who should get it and how to act on your result.
