Frequently Asked Questions
Can I take Nattokinase with my current medications?
Can I take Nattokinase with my current medications?
For most people, yes. Nattokinase is a natural enzyme and doesn't interfere with most common medications. Many people take it alongside statins, blood pressure medications, and other heart-related supplements without issue.
However, if you're currently taking blood thinners (likeWarfarin, Eliquis, or aspirin therapy), you should consult your doctor before adding Circulene to your routine, as nattokinase supports fibrin breakdown and may enhance their effects. If you have an upcoming surgery, discontinue use at least2 weeks prior. If you have any concerns, we encourage you to speak with your doctor before starting.
How long before I see results?
How long before I see results?
Many people notice improved circulation, lower blood pressure, and relief from symptoms like leg heaviness or swelling within the first few days to a couple of weeks. These early wins are signs your body is responding.
For long-term cardiovascular benefits, it may take several weeks to a few months of consistent use. The studies showing plaque reduction were over a 6-12 month period. For this reason we offer generous quantity-based discounts for larger orders.
Are there any side effects?
Are there any side effects?
Nattokinase has been consumed in Japan for over 1,000 years with an excellent safety record. Most people experience no side effects. However, if you're on blood thinners or have a bleeding disorder, do not take nattokinase without consulting your doctor first.
Is Nattokinase safe for long-term use?
Is Nattokinase safe for long-term use?
Yes. Nattokinase is derived from nattō, a fermented soybean product rich in probiotics, vitamin K2, and nattokinase, which may support heart and bone health.
It's generally well-tolerated and research suggests it may support cardiovascular health over time.
For most healthy individuals, regularly eating natto as part of a balanced diet is safe and may even offer long-term health benefits. If you have any specific health concerns, it's always a good idea to check with your healthcare provider.
