Nattokinase - uses and benefits

This brief review is an enthusiastic survey of nattokinase, the fermented-soy enzyme, across an unusually wide range of conditions — cardiovascular, neurological, hematologic, even obstetric.

The claims echo the broader nattokinase literature: thrombolytic, blood-pressure-lowering, anti-atherosclerotic, lipid-lowering, and neuroprotective effects, drawn from a mix of test-tube, animal, and a few human studies. The author positions it as a cheap, well-tolerated, over-the-counter option for people seeking non-pharmaceutical cardiovascular support.

The status-quo framing is explicit — an unpatentable food enzyme that, if it worked as broadly as claimed, would undercut statins, aspirin, and antihypertensives, and so faces commercial and institutional headwinds.

Our rating is low, and lower than other nattokinase reviews for good reason. We score the evidence at the bottom of the range: a regional-journal narrative review with limited conflict disclosure, leaning on small or animal studies of varying rigor. Its clinical significance is correspondingly low — the breadth of claims outruns the quality of evidence by a wide margin, so this may inform a supplement decision but cannot support a clinical one. Read it as a hypothesis catalog, not a guide.
