The time it takes to see results from taking nattokinase can vary depending on the individual and the reason for taking it. Some people report improved circulation, reduced blood pressure, or relief from symptoms like swelling or heaviness in the legs within a few days to a couple of weeks. 

However, for long-term cardiovascular benefits, it may take several weeks to a few months of consistent use. The studies showing results breaking down artery plaque were over a 6-12 month period. For this reason we offer very generous quantity based discounts for larger quantities. 

Nattokinase is a natural enzyme extracted from natto, a traditional Japanese food made by fermenting soybeans with Bacillus subtilis bacteria. It is known for its ability to break down fibrin, a protein involved in blood clotting, which gives it potential cardiovascular benefits such as supporting healthy blood flow and reducing the risk of blood clots. 

People often take nattokinase as a dietary supplement to help maintain heart health, manage blood pressure, and promote circulation. Unlike some blood-thinning medications, nattokinase is considered a more natural option.

Nattokinase is generally considered safe for most people when taken in appropriate doses, but it can have side effects, especially for those with certain health conditions or who are taking medications. As a potent blood thinner, it may increase the risk of bleeding, particularly if combined with other anticoagulants like aspirin, warfarin, or supplements like fish oil. Some people may experience mild side effects such as stomach discomfort, nausea, or headaches. It's also not recommended for people with bleeding disorders, upcoming surgery, or for pregnant and breastfeeding women without medical supervision. Always consult a healthcare provider before starting nattokinase, especially if you're on medication or have underlying conditions.

Yes, natto is generally considered safe for long-term use when eaten as a food, especially as part of a traditional Japanese diet. It's a fermented soybean product rich in probiotics, vitamin K2, and nattokinase, which may support heart and bone health. However, due to its blood-thinning effects from nattokinase and high vitamin K2 content, people on blood thinners (like warfarin) should be cautious, as it can interfere with medication. For most healthy individuals, regularly eating natto as part of a balanced diet is safe and may even offer long-term health benefits. As always, moderation is key, and it’s a good idea to check with a healthcare provider if you have any specific health concerns.
