Vitamin K2 has been removed
Been taking two capsules daily for a while and just noticed it says Vitamin K2 removed. K2 helps calcium go to the bones an not the heart and arteries. Blood pressure is adversely affected by arterial wall hardening and narrowing. I would prefer to leave the K2 in my Nattokinase. Moving to a different make.

GO FOR IT –
It is a great product for SOME people
I felt obligated to write a review about “Doctor’s Best Best Nattokinase (2, 000 Fu)” because the improvement my family felt over last 2 years. You are right, 2 years, which qualifies me to write a meaningful review on it.Why did my family start to use it? My father had a heart attack two and a half years ago. The ECG & MRI diagnoses were not good and he also had Embolism. With traditional treatment, I started looking for additional supplements that could help. After some research, I found Nattokinase could be one choice and “Doctor’s Best” is quite reputable with very reasonable price. So everything happened there.What is the benefit? The improvement is STEADY and HUGE. AFTER CONSULTING THE DOCTOR, my father started taking the 2k Fu pills everyday. Because some worries about potential risks (see below), I asked him to take 1 pill a day in warm seasons and 2 pills a day in cold seasons, and asked him to regularly do the blood tests. After 1 year, the ECG result showed an improved T-wave from -4 to -3 (I’m not professional and the numbers are direct readings from the ECG curve which was explained by the doctor “a good sign of improvement”). And last week, after 2 years of taking the pills, the T-wave is lifted from -3 further to -2 plus significant improvement in body feeling. According to the doctor, this is GREAT!What is the other benefit? I started to take it about 1 year ago because my blood pressure is a bit high and I know my blood is very viscous. I constantly monitored my blood pressure afterwards and found that it decreased from average low@86~high@131 to low@75~high@119 in about a year. I’m not taking any other blood pressure control pills and my diet habit is the same. So this is definitely due to Nattokinase. And I’m happy about it.What are the RISKS? While doing the research before buying, I noticed there is a scientific paper (published) discussed the improvement of blood mobility (reduction of viscosity) after treatment of Nattokinase (many adults were taking the pills and their blood samples were tested over some time period). And then there are reports stating that longer time is needed to stop bleeding and unexpected bleeding occurs while some people brushing the teeth after taking Nattokinase. So I think there must be risks about it. And indeed, my mom can’t take it because several days of Nattokinase intake would always cause her teeth to bleed after brushing. So for those who have this kind of problem, be careful. The best way is to always consult your doctor before taking and when anything unusual happened after taking.In summary,Pro: It worked in my cases; Pills are small; “Doctor’s Best” is a good brand.nothing really bad, you just need to know if it fits you.
Amazon Customer –
Has maltodextrin in it
It has maltodextrin as an ingredient, maltodextrin has many negative effects in the human body, it is considerably higher in the glycemic index than sugar.As a filler, why?Last time I’m purchasing this product.
Michelle Lim –
Great!!!! product will buy again.
Luis –
Tiene maltodextrina que aunque justifiquen que es para preservar el producto, esto bien lo pudieron haber omitido porque simplemente no es necesario y no es bueno para la salud.
Nirali T. –
Very nice product!I bought them for my uncle and aunt. Both have liked the product.However, they have jacked up prices by 150%. I bought 270 pills at about Rs. 16 per pill, now its touching Rs. 24/- ! So I switched to a different brand.Seems they dont like repeat business or they are trying to earn too fast!Product Reviews are 5 Star !
