5 Scientific Studies That Reveal the Power of Nattokinase
In the quest for natural solutions to support our well-being, ancient wisdom often points the way. For centuries, a traditional Japanese food called natto, made from fermented soybeans, has been a dietary staple, celebrated for its unique flavor and health-promoting properties.
The secret behind its power lies in a potent enzyme: nattokinase. But this isn’t just folklore; modern science is now validating what tradition has long suggested.
Ready to explore the science behind this incredible enzyme? This article dives into five significant scientific studies that highlight the impressive health benefits of nattokinase, from supporting cardiovascular health to promoting clear circulation.
Let’s look at the evidence and discover why this natural enzyme is gaining well-deserved attention in the health community.
1. Nattokinase and its Fibrinolytic (Anti-Clotting) Activity
One of the most celebrated benefits of nattokinase is its ability to break down fibrin, a protein involved in blood clotting. While clotting is essential for healing, excessive fibrin can lead to unhealthy circulation.
A foundational study published in Acta Haematologica investigated this effect directly. Researchers administered a single dose of nattokinase to healthy men and observed its impact on their blood.
The results were remarkable: within hours of consumption, the participants showed a significant enhancement in their body’s natural ability to dissolve blood clots.
The study demonstrated that nattokinase boosts the activity of plasmin, the body’s own enzyme for breaking down fibrin. This powerful fibrinolytic action is a cornerstone of nattokinase’s role in promoting healthy blood flow and cardiovascular wellness.
2. Supporting Healthy Blood Pressure Levels
High blood pressure is a widespread concern, but nature may offer a gentle way to help manage it. Nattokinase has been shown to have a positive influence on blood pressure by inhibiting an enzyme known as angiotensin-converting enzyme (ACE). ACE causes blood vessels to narrow, and by inhibiting it, nattokinase helps them relax.
A randomized, double-blind, placebo-controlled trial published in Hypertension Research provides compelling evidence. In this study, 86 participants with pre-hypertension or stage 1 hypertension took nattokinase daily for eight weeks.
The group taking nattokinase experienced a significant reduction in both systolic and diastolic blood pressure compared to the placebo group. This study highlights nattokinase as a promising natural approach for maintaining blood pressure within a healthy range, offering a supportive tool for cardiovascular health.
3. Enhancing Circulation and Reducing Blood Viscosity
Imagine your circulatory system as a network of highways. Smooth, flowing traffic is ideal, but thick, slow-moving blood can create congestion. Nattokinase appears to act like a natural traffic controller, improving blood flow by reducing its “stickiness.”
A study featured in the Journal of Food Science and Technology explored this very effect. Participants were given nattokinase for two months, and researchers measured changes in blood viscosity and other cardiovascular markers.
The findings showed that nattokinase supplementation significantly lowered blood viscosity. By making the blood less thick and more fluid, the enzyme helps it flow more easily through blood vessels, nourishing tissues and organs throughout the body. This is especially crucial for individuals looking to maintain robust circulation and overall vitality.
4. Nattokinase’s Effect on Atherosclerosis (Hardening of the Arteries)
Atherosclerosis, the buildup of plaque in the arteries, is a serious cardiovascular risk. Finding natural ways to slow its progression is a major goal in preventive health. Nattokinase has shown potential in this area by directly impacting arterial health.
In a pivotal study published in Scientific Reports, researchers followed 76 adults with atherosclerosis. Over 26 weeks, one group received nattokinase while the other received a statin drug. The results were astonishing.
While both groups saw benefits, the nattokinase group experienced a significant reduction in arterial plaque size—even outperforming the statin group in some measures—and an increase in beneficial HDL (good) cholesterol. This suggests that nattokinase not only supports healthy blood flow but may also help maintain the structural integrity of the arteries themselves.
5. Potential Neuroprotective Benefits
While much of the research focuses on cardiovascular health, emerging science suggests nattokinase may also protect the brain. Healthy blood flow is critical for cognitive function, and by ensuring the brain receives a steady supply of oxygen and nutrients, nattokinase can play a supportive role.
A study published in the Journal of Agricultural and Food Chemistry investigated the neuroprotective properties of nattokinase in a laboratory setting. Researchers found that the enzyme could break down amyloid fibrils, protein aggregates that are hallmarks of certain neurodegenerative conditions.
While this research is still in its early stages and primarily conducted in labs, it opens up an exciting new frontier for nattokinase. It suggests that by promoting clear circulation and breaking down harmful protein buildups, nattokinase could be a valuable ally in preserving long-term brain health.
Natural Insights
The scientific evidence is clear: nattokinase is a remarkable enzyme with a wealth of potential health benefits, deeply rooted in both tradition and modern research. From promoting healthy blood flow and blood pressure to protecting our arteries and even our brains, its power is undeniable.
If you’re inspired to incorporate the circulatory benefits of nattokinase into your wellness routine, this powerful enzyme, derived from fermented soybeans, is known to support heart health and promote healthy blood flow. Adding it to your daily regimen could be a simple yet effective step toward improving your overall well-being.
