Nattokinase is garnering attention for its potential health benefits, particularly in heart and blood vessel health. It's an enzyme derived from natto, a traditional Japanese food made from fermented soybeans, and produced by the bacterium Bacillus subtilis. There are claims about its ability to dissolve fibrin, which may help in preventing blood clots, and lowering risks associated with conditions like high blood pressure, atherosclerosis, deep vein thrombosis, poor circulation, and stroke. It's also being studied for its potential in treating Alzheimer's disease by breaking down plaques associated with the condition, although more research is needed to confirm these findings.
However, the evidence surrounding nattokinase is not without contradictions and concerns. While it's suggested to have clot-busting properties and might help in reducing blood pressure, its effectiveness as a supplement has been questioned due to inconsistent results and lack of robust data. For instance, discrepancies have been noted in the timing of its peak action in the bloodstream after ingestion, and there's uncertainty about how it behaves when taken orally, including questions about whether it's broken down by stomach acid or absorbed through the intestinal wall. The presence of numerous brands in the market with limited data on their efficacy adds to the ambiguity.
Moreover, it's crucial to approach nattokinase with caution due to possible side effects and interactions, especially if you're on blood-thinning medication or have bleeding disorders. It's reported to potentially increase the risk of bleeding, and there have been cases of adverse reactions like shortness of breath, mild chest pain, internal bleeding, and even severe allergic reactions in some individuals. So, it's highly recommended to consult healthcare providers before starting any new supplement regimen, including nattokinase.
Despite the promising aspects, the lack of comprehensive clinical data and the presence of safety concerns necessitate a cautious approach and underline the importance of further research to validate the claimed benefits and ensure safe use.
