Nattokinase Supplement 4,000 FU Servings, 120 Capsules (Derived from Japanese Natto) Systemic Enzymes for Cardiovascular and Circulatory Support by Double Wood

Easy to swallow , love the clean ingredients . Very effective.

Used as part of a 3-supplement combo to mitigate spike protein. Not sure exactly what effect this supplement has alone, but I have noticed a decrease in some side effects that I associate with having had the vax. The 3-supplements were Nattokinase, Bromelain, and curcumin(curcumin, turmeric, and black pepper).

I’m 63 years old and I’ve never had a soy intolerance until I started taking this supplement. It must have a high concentration of soy in it because after a week, I started having the following: nausea, bloating, extreme cramping, headache and diarrhea. I had to throw it away and order a soy free brand. Please be careful if you have ever had a soy intolerance because this got so bad I almost had to seek medical help.

I find the product as described on the selling page to be very misleading. First it states that it is Japanese natto. So you might think it is sourced from Japan. Then it states proudly made in the USA. People who buy this type of product do their research. Unlike a multi-vitamin, we take it for a very specific reason. So where it is sourced from is very important to us. I sent an email to customer service and they did respond right away. That is the reason, and along with the honest reply they provided me was the reason they got two stars, instead of one. According to customer support, the source of this Nattokinase comes from China. It is "manufactured in the USA. What does manufactured mean? It means they take the powder (from China) and fill the capsules in the USA. That's it. I do not want to consume (ingest) anything that comes from China. From deadly dog biscuits, faked baby formulas are just 2 reasons I avoid Chinese made ingredients.. There are many more reasons. I wish these supplement manufactures would just be honest in the descriptions about the source of the supplement. I would even pay more if they had the source come from a more reputable country. It's not about saving money, it's about trusting the quality. Testing so what? They made baby formula test higher proteins levels by messing with it chemically. They (China) have ways to fake stuff so there is a massive trust issue. I will simply stay away from the product than take a chance.

Works as an additional blood thinner

Blood pressure was reduced 10% after a week of use.

I didn’t know the section your blood. I had a micro tear in my knee and wound up in the ER when my knee filled with blood. Be careful.

I am certain that this supplement helped my lipoprotein little aWhich is a genetic marker for my heart, definitely recommend.
