In a Nutshell

High-dose nattokinase can regress arterial plaque, lower blood pressure, and reduce clotting. TUDCA, berberine, omega-3s, and 2 g/day vitamin C each target distinct drivers—arterial inflammation, LDL clearance, heart-rate variability, and Lp(a) stickiness—while mitigating statin side-effects and possibly slowing brain aging. Together they form a practical, low-cost toolkit for protecting cardiovascular and metabolic health.

I did a 7-year experiment where I live with cholesterol levels higher than most doctors see in their entire careers. When I underwent advanced heart imaging, there was no plaque whatsoever in my heart. My heart was astonishingly pristine. Everyone started asking for my secret. How do you build a heart that appears resistant from heart attack, from atherosclerosis? In this video, I'm going to walk through some of the highest yield strategies when it comes to protecting cardiovascular health. We're going to explore sides of cardiovascular biology you definitely don't learn in medical school, information drawn from thousands of hours of study, dozens and hundreds of papers. To respect your time, I'm going to do my best to boil down the highest yield, most practical information into 20 minutes.

Rather than just rattling off supplements and lifestyle actions, I have with me a little toolbox. I want to frame this as a practical toolkit for cardiovascular health, so I want to make it visual. We're going to go through this toolbox. Inside, there are five tools for heart health, each represented by a different object in this mystery bag.

Tool number one, represented by a scoop, is nattokinase. I use this ice cream scoop to represent nattokinase because it's one of the few compounds suggested to actually reverse plaque progression or scoop out plaque from arteries. In one large human study involving over a thousand participants, individuals taking high-dose nattokinase for one year showed regression of atherosclerosis heart disease. Using ultrasound imaging of the carotid arteries going from the heart to the brain, researchers observed a 22% reduction in carotid intima-media thickness and a 36% reduction in coronary plaque surface area. Even if it's not a perfect study, and no studies are perfect, this is a finding not to be overlooked.

Nattokinase is an enzyme derived from a traditional Japanese fermented soybean dish called natto. It's been consumed for over a thousand years, and that dish, natto itself, is actually linked to lower rates of cardiovascular mortality on the order of 25% lower rates compared to those who consume basically no natto.

How Nattokinase Works

There are three main effects. First, anti-clotting activity. Effectively, nattokinase makes the blood less sticky and less prone to build up clots and debris in arteries. Second, blood pressure reduction. This has been shown in human randomized controlled trials. Nattokinase reduces blood pressure, which is a risk factor for heart disease. It acts by inhibiting an enzyme called angiotensin-converting enzyme, ACE. By reducing ACE activity, nattokinase allows your arteries to relax, lowering blood pressure and improving cardiovascular risk in the process. Third, nattokinase can reduce oxidative stress. Oxidative stress plays a central role in vascular damage, inflammation, and heart disease. Nattokinase helps by increasing antioxidant defenses, protecting against blood vessels. Nattokinase is like the Pac-Man that gobbles up free radicals.

To get the best effects, you probably need higher doses, on the order of 10,000 fibrinolytic units or more.

The next tool is an ice pack, representing TUDCA. The reason I choose this ice pack is because one of the most interesting aspects of TUDCA is its effects on inflammation, particularly calming inflammation within the artery wall. TUDCA is actually a gut hormone that can be made by your microbiome, and it's also a supplement.
