Can a fermented soybean enzyme actually reverse arterial plaque? In this video, we dive deep into the science behind nattokinase—one of the most misunderstood yet promising supplements in cardiovascular health. From its ancient samurai-era origins to modern clinical studies, we unpack whether this enzyme can truly lower your risk of heart disease.
You'll learn how nattokinase works on a biochemical level—breaking down blood clots, lowering blood pressure, and reducing oxidative stress. We'll examine the latest research, including a 1,000-person study showing potential regression of atherosclerosis and improvements in cholesterol markers. And yes, we’ll talk dosing, safety, and how this fits into a broader heart health strategy.
If you care about your heart, aging well, or simply staying ahead of the curve on evidence-based supplements, this one’s for you. For all the references, visuals, and extra resources (including my recommended 5-ingredient heart stack), check out the StayCurious metabolism letter at staycuriousmetabolism.com
