500mg Melts Clogged Arteries by 37% (Study Backed)

Summary

The presenter discusses nattokinase, an enzyme derived from fermented soybeans, and its possible effects on arterial plaque. He describes a study in older adults in which 10,800 fibrinolytic units per day was associated with a 36% reduction in carotid plaque size on imaging. He says 3,600 units showed no measurable effect. Reported reductions were larger among participants who exercised regularly (37.5%) than among sedentary participants (31%).

The subtitles do not identify the study or its authors, so these figures are the presenter’s account rather than independently verifiable details here.

Key Points and Strategies Discussed

• Exercise: The presenter says regular exercise was associated with a greater plaque reduction in the study and suggests it may complement nattokinase rather than replace it.
• Check supplement labels: He advises looking for fibrinolytic units, not just milligrams, because products may list different measures. He points to about 10,800 units as the dose used in the study he describes; this should not be taken as a personal dosing recommendation.
• Be cautious about bleeding risks: The video says nattokinase can affect blood clotting and warns that bleeding after a fall or head injury may be especially serious for people taking blood thinners.
• Do not casually substitute or combine it with prescription blood thinners: The presenter warns against combining nattokinase with medicines such as clopidogrel, warfarin, apixaban (Eliquis), or rivaroxaban (Xarelto). He also describes a case in which replacing warfarin with nattokinase led to a severe clot. Do not stop or change prescribed medication without medical advice.
• Tell clinicians about supplement use: The presenter says to inform a doctor before surgery and suggests stopping nattokinase one to two weeks beforehand. Any decision to pause a supplement before a procedure should be confirmed with the treating clinician.
• Evaluate evidence carefully: The presenter encourages choosing supplements based on research for the intended outcome. The subtitles do not provide citations or enough study details to assess the evidence, and the plaque findings described should not be treated as proof that nattokinase prevents heart attacks or strokes.
