Decided to use Nattokinase when side effects from Plavix became intolerable. While using it, had no TIAs though I did with Plavix. Stopped the natto' briefly to try to return to Plavix due to Dr's wishes, had visual disturbances and tinnitus immediately. Also all my joint and muscle pain mysteriously goes away on the Nattokinase, some skin tags disappeared, and I just feel better. I take one Doctors' Best 2000 mg every other day just before sleep or in middle of the night to assure no food interferes with its absorbtion. Even if it doesn't replace Plavix, I will take it, as it erradicates my 24/7 knee/body inflamation pain totally. Read More Read Less

Condition:

I was diagnosed with DVT in my leg after a fall from a ladder that kept me in a chair for months. I was put on warfarin and stayed on it for three years. Got tired of getting blood tests sometimes weekly.Went off it and sometimes took asprin and sometimes 50 mg natto. instead. After being woke up at night with tingling in arms and legs, took more natto. 100mg (2000fu) before bed. After reading reviews here, decided to use the kind with vitamin K removed. First day, took 100mg 3 times a day, That was too much for me cause I didn't feel right after the 3rd dose before bed. Trying 100mg at 8pm took me to 4am before being woke up with tingling. Going to try 100mg at 10pm next. When texting a review, plese include your doses!!!Read More Read Less

I have been taking this for help with menstrual cramps. I find it to be effective, but it is hard to make sure to take it on an empty stomach.

Looked for an alternative to Warfarin. Agreed with UK vascular consultant that I would use instead of Warfarin after an initial 3 months self injecting Heparin. Been using for 16 months. Very effective.

Condition: Protein-S Deficiency My husband was told he couldn't have the IV antibiotic treatment he needed for his neurological lyme disease because he was so severely deficient in anti-clotting factor, protein-s. Normal range: 60-145, His result: 9! They said they'd retest in a month. I read everything I could find on protein-s and decided to give him nattokinase for it's high vitamin k content. When they retested him a month later, his level had risen from a 9 to a 95, well within normal range and he was able to go on IV antibiotics for his lyme disease, which has given him his life back.

Heart has remained in Atrial Fibrillation for 9 years. Took Coumadin following several orthopedic surgeries, but am not willing to take it long term. Have taken Nattokinase for at least 3 years. Recently had a cardiac catheterization and they found no blockages. I attribute that to the nattokinase.

Have AF. No blood clots in over 10 years! No side effects.

Condition:

Diagnosed Stage IV breast cancer metastases 2-1/2 yrs ago. Refused tamoxifen after year treating Stage II in 2001 because of possible clotting issues. Had a tia both times after abruptly stopping estrogen (stopped birth control pills in '74 then started estrogen inhibitors in 2011). Seattle research doc. suggested nattokinase. I'm on 2000FU/day w/o food. (4000/day made me dizzy; I have naturally low blood pressure) Now feel confident about being able to take Tamoxifen when present ER blocker stops working. Not on chemo yet which is a huge praise! Wish more people knew about this natural supplement. Seems much better for folks than big pharma drugs...Read More Read Less

I have atrial fibrillation. Nattokinase is my treatment of choice, as opposed to coumadin or xarelto. NO SIDE EFFECTS.

Condition:

Started getting bloody noses after about a month of taking it in conjunction with Warfarin (Coumadin) to see if my INR Blood Test levels would go up (thinner blood). Did not show up on the VA tests. What tests are run to determine its effectiveness? Why does the VA NOT RECOMMEND it to me as a "safer," alternative treatment? They told me that if I go off of Warfarin, I have a 40% chance of getting another DVT clot within 10 years (had 2 already, in both lower legs). Can anyone help me out?

Condition:

I've been taking it for 5 years in place of a blood thinner. I feel better now and have had good results and no clots.

I have Peripheral Artery Disease. I got it in my late 40s due to blood coagulation problem. I also had very high cholesterol (over 300+ my entire life). I had difficulty walking by age 50. I put myself on high dose nattokinase and serrapeptase and the symptoms disappeared within 6 weeks. You will know it is working within 1 month. I eat as much cholesterol as I want. I have been on this over 6 years. I am on maintenance dose. Just experiment with dosage over time to get the minimum dose and cost. Please be aware that conventional medicine perpetuates lies about cholesterol. Just take the time to look at the studies. If the arteries are clean enough, you won't have heart disease. Ignore the cholesterol propaganda. They have Nattokinase made from bacteria and fungus, with and without vitamin K. Both work but I prefer the Nattokinase with Vitamin K. Without vitamin K is for people on prescriptions drugs. I take Best Nattokinase and Serrapeptase. I buy from Swanson vitamin because they are cheap. iI'm amazed they don't have Heart disease category for this. Chinese have done thousands of studies on effectiveness of fibrolytic enzymes for heart attack and stroke prevention. Read More Read Less

Condition:

My Mom is a GI bleeder and cannot tolerate aspirin, nsaids, plaxix, pradxa, etc., She is a stroke victim and has heart disesae. This is the only anti-thrombolytic she can tolerate. She's been on it now since 2006 with no more GI problems. It also helps @300mg/QD with her DVT's.

I've suffered high blood pressure and high triglyceride levels. I have suffered what it used to a "minor" heart attack in the past due to a blockage of artery in my heart. But since taking nattokinase, I have been able to control my blood pressure without drug prescriptions, and my triglycerides and the good cholesteral level are normal. And all this, without going to extremes in watching my diet.

Condition: Other

it really does work in preventing blood clots and digesting any present

Condition:

My 53 yr. old Son's deep vain clot showed on test, at the hospital, that 'Natto' was desolving the clot, so I starded to using the 'Natto NSK-SD,2000-FU'( WITH-OUT VIT-K ), my self, first thing each morning before any food, it does so much more, to help our bodies,(not harm like-DRUGS, THAT COVER THE REAL PROBLEM ), then any other blood thinner, and is safer, EVEN AFTER 12 HOURS, USING ONE BABY ASPIRIN FOR A LITTLE HEADACH,,WAS JUST FINE,,I hope to never be cought with-it,,and it's up-keep of my whole body,( it seems, from all my research). I tell all my family about-it. AND I'M SO THANKFUL, AT THIS TIME i'M NOT ON ANY DRUGS Read More Read Less

I was diagnosed with antiphospholipid syndrome along with low factor VIII levels in December of 2007. I had had numerous tia's previously. Because of the low factor VIII levels I was not a candidate for wayfarin but my hematologist put me on coumadin. After 4 months it was determined the coumadin was also imcompatible; my hematologist literally told me to get my will in order as nothing could be done. I found out about nattokinase and found a pharmaceutical grade brand containing no vitamin K. Have been taking 400 mg. daily, divided, without food, for 4 years now. No bad side effects at all. Cannot take aspirin with it. The good benefits? I have had a few tia's, yes - perhaps 5 total in 4 1/2 years. But when you compare that to the average of perhaps 4 per month was having in the 6 months prior to being diagnosed, this is amazing. It took the doctors that long to diagnose me and I was so fortunate not to have had a major stroke. I also watch my diet, not eating vegetables high in vitamin K. Other than that I feel I owe nattokinase my life. I so wish it would be properly tested and therefore approved.Read More Read Less
