Understanding Nattokinase

Nattokinase is a powerful enzyme derived from natto, a traditional Japanese food made from fermented soybeans. Natto has been enjoyed in Japan for over a millennium for its unique taste and health benefits. Dr. Hiroyuki Sumi discovered nattokinase in 1980, noting its impressive ability to dissolve fibrin, a key protein in blood clotting.

Nattokinase is renowned for its cardiovascular benefits. It breaks down blood clots, crucial for preventing strokes and heart attacks. This enzyme enhances the body’s natural clot-dissolving processes by activating plasminogen to plasmin, the primary enzyme for clot breakdown.

Additionally, nattokinase lowers blood pressure by inhibiting the angiotensin-converting enzyme (ACE), similar to some blood pressure medications. This dual action of reducing clot formation and lowering blood pressure makes nattokinase a promising natural option for cardiovascular health.

However, caution is necessary. Potential risks include severe allergic reactions, excessive bleeding, and interactions with blood-thinning medications. Always consult a healthcare provider before starting nattokinase supplements.

In summary, nattokinase, from the traditional Japanese food natto, offers significant cardiovascular benefits through its clot-dissolving and blood pressure-lowering properties. Yet, careful monitoring is essential to avoid adverse effects.

Mechanisms of Action: How Nattokinase Works

Let’s delve into the science behind nattokinase and its impact on cardiovascular health. This enzyme, derived from natto, plays a crucial role in dissolving blood clots and managing blood pressure.

Fibrinolytic Activity: Dissolving Blood Clots

Nattokinase stands out for its fibrinolytic activity, crucial for cardiovascular health. It breaks down fibrin, the protein forming blood clots. Here’s how it works:

• Inactivation of PAI: Nattokinase cleaves and inactivates plasminogen activator inhibitor (PAI), enhancing tissue plasminogen activator (tPA) activity, converting plasminogen to plasmin, the main clot-breakdown enzyme.
• Direct Fibrin Degradation: It also directly degrades fibrin, though less pronounced, contributing to its fibrinolytic activity.
• Enhanced Thrombolysis and Anticoagulation: Studies show a single dose significantly increases fibrin/fibrinogen degradation products, indicating enhanced thrombolysis (PMC).

Consult your healthcare provider before starting nattokinase, especially if on anticoagulants.

Anti-Hypertensive Benefits: Managing Blood Pressure

Nattokinase shows promise in managing blood pressure. It inhibits angiotensin-converting enzyme (ACE), reducing blood pressure by relaxing blood vessels. A study in Food Function confirmed significant ACE inhibition in subjects consuming nattokinase.

Additionally, it reduces blood viscosity and improves circulation. A 2008 clinical trial showed participants taking nattokinase had notable reductions in systolic and diastolic blood pressure (Hypertens Res).

Monitor blood pressure regularly when using nattokinase, especially if on antihypertensive medications. Always consult with a healthcare provider before starting any new supplement.

Anti-Inflammatory Properties: Reducing Inflammation

Nattokinase, derived from fermented soybeans, has notable anti-inflammatory properties. Chronic inflammation can lead to cardiovascular and neurodegenerative diseases. Studies show nattokinase mitigates neuroinflammation and apoptosis linked to Alzheimer’s disease (Bhatt et al., 2017).

Additionally, nattokinase enhances preventive effects on colitis in mice (Liang et al., 2022).
