thank you
Nattokinase is a natural enzyme extracted from fermented soybeans (natto) that is known for its potential benefits in supporting healthy circulation and normal blood flow. It can be a valuable addition to a heart-healthy regimen when taken alongside other supportive supplements like omega-3 fatty acids. Buying this for my dad and mom to take frequently.

Better than prescription drugs, with no side effects
Been taking it for years. Really seems to help keep my arteries from clogging up. My doctor says keep doing what I'm doing!

BLOOD FLOW
Nattokinase helps keep my blood flowing--hopefully to avoid blood clots. Have been taking it for years. It was recommended to me by an acupuncturist I was seeing at the time.

I give it a 5 star rating. I take it with one amla pill, each day, to keep my blood healthy, viscous, and immune from clotting that could bring on a stroke. I highly recommend this product for the elderly; there are no bad side effects.

BAD FILLER IN PRODUCT, WOULD NOT USE
Because it contains a VERY BAD filler (DI-CALCIUM PHOSPHATE) I returned it immediately. I would not use it or recommend it. Di-calcium phosphate is a VERY BAD filler. The body is not able to utilize it properly, therefore it may be deposited in the muscular or vascular system potentially causing serious problems.

I think this can save lives.
I have used this for seven or more years. I’m not a doctor, but I believe it dissolved a clot I had in my leg a long time ago. I use it religiously for a healthy circulatory system.

Nattokinase works
Started working on the first day. As an older (70 yr.) blood donor the veins were getting difficult to locate. Soon after taking Nattokinase, veins were larger, blood flow was easier, and also my brain seemed to benefit from the increased blood flow. I recommend this product.
