Nattozimes
Also known as: Nattokinase, Fibrinolytic enzyme, Bacillus subtilis var. natto enzyme
Overview
Nattokinase is a fibrinolytic enzyme derived from soybeans fermented by the bacterium Bacillus subtilis var. natto, mainly featured in the traditional Japanese dish known as natto. It has gained considerable recognition for its cardiovascular benefits, backed by multiple studies showing its efficacy in lowering blood pressure, managing cholesterol levels, and preventing blood clot formation. Nattokinase is available in dietary supplements and various food products. Systematic reviews and randomized controlled trials suggest that it may serve as an adjunct therapy to enhance cardiovascular health outcomes. Despite its promising applications, additional research is needed to clarify its broader health benefits and to establish optimal usage guidelines for different demographic groups.
Benefits
Nattokinase has been linked to several cardiovascular health benefits supported by robust evidence. Meta-analyses indicate significant reductions in systolic blood pressure (mean difference = -3.45, p < 0.00001) and diastolic blood pressure (mean difference = -2.32, p < 0.00001), particularly in hypertensive individuals. Lower doses (2000-4000 units) have shown a mean reduction in total cholesterol (mean difference = -5.27, p < 0.00001) and a decrease in high-density lipoprotein levels (mean difference = -2.76, p < 0.00001). However, higher doses did not demonstrate significant lipid-lowering effects, highlighting nattokinase's role as a complementary treatment for cardiovascular issues, especially in individuals at greater risk or those with pre-existing hypertension.
How it works
Nattokinase primarily improves cardiovascular health through its fibrinolytic activity, breaking down fibrin, a key component in blood clot formation. This enzymatic function facilitates fibrinolysis, preventing thrombus formation and potentially aiding in blood pressure regulation. Additionally, nattokinase may impact lipid metabolism pathways, leading to improved lipid profiles, although responses might vary based on dosages employed.
Side effects
Nattokinase is generally considered safe, with a low incidence of side effects reported. Mild gastrointestinal disturbances are noted in fewer than 5% of users. Severe side effects are rare, but caution is advised for individuals on anticoagulant or antiplatelet medications due to increased bleeding risks. When taken alongside antihypertensive drugs, there may be a potentiated blood pressure-lowering effect, which could lead to hypotension. It is essential for individuals with bleeding disorders to avoid nattokinase. Additionally, users should cease supplementation at least two weeks before any surgical procedures. The safety of nattokinase during pregnancy and breastfeeding remains uncertain, hence utilizing natto as a natural source may be a safer alternative.
Dosage
Effective dosages of nattokinase generally range from 2000 to 7000 fibrinolytic units per day. Specifically, lower doses (2000-4000 units) are particularly effective for blood pressure regulation. A maximum safe dosage has not been established, with doses up to 7000 units tolerated well. Nattokinase is available in capsule or tablet forms and is typically recommended to be taken once or twice daily. It can also be consumed through natto in one’s diet. Due to limited absorption data, adherence to recommended dosages is crucial for ensuring optimal efficacy and safety.
FAQs
Is nattokinase safe for everyone?
Nattokinase is generally safe, but those with bleeding disorders or on anticoagulant medications should use it cautiously due to bleeding risks.
When is the best time to take nattokinase?
Nattokinase can be taken once or twice daily; however, specific timing is not crucial, allowing flexibility.
What results can I expect from using nattokinase?
Users typically see reductions in blood pressure and potential improvements in cardiovascular health, although lipid profile enhancements may vary.
Is it true that nattokinase benefits all cardiovascular conditions?
While nattokinase has shown benefits for blood pressure, its effects on other cardiovascular conditions require further research.
