User Reviews for nattokinase

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.

Lupus can cause blood clots,that i why i use this product.

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.

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.

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?

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

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.

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

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

I have MTHFR C667T and my husband has MTHFR A1298C and we miscarried 4 babies on Lovenox. So I tried nattokinase 2 times a day and now have a beautiful princess! I still take it to prevents clots and fibroids.

Doctor advised to have inr of 2.5-3.5 I take 8 pills of 1500 Fibrin Units (8x1500=12000 units) in addition to 5 mg of coumadin. my blood INR is only 1.2 after several weeks. If you have a serious illness and have "thick blood" syndrome, don't bother wasting money on this (for it to be effective apparently you have to take way more than I want to take!). If you are using it for other reasons, it may work.

I am using nattokinase and serrapeptase to shrink some large uterine fibroids. So far it is working, I estimate that since my fibroids are large it will take up to 6 months for my belly to flatten. but so far i can feel they are getting smaller.

I had a six inch clot in my inferior vena cava which blocked 90 percent of the blood flow. My hematologist stated after examining me that he could do nothing and that I was a walking time bomb. I react badly to Coumadin and I had DVT in my right leg which blocked blood flow on all outside veins from ankle to groin so I chose a Nattokinaise that did not contain vitamin "K". The major clot is almost totally dissolved and the blocked veins in my leg have regained much of their blood flow. I have been taking 300 mg. twelve hours apart. I have not experienced the headaches I had with Coumadin nor the elevation in blood pressure in excess of 240 systolic, which happened on several occasions. I was careful not to take anything that might act as a blood thinner and not to consume green vegetables rich in vitamin "K" during my use of Nattokinaise. Now that the clot has been greatly reduced, my doctor placed a "Greenfield" filter in the vena cava, above the blood flow from the right leg; I shall worry less about the remaining clots. I thank GOD for the people that make this type of Nattokinaise as I was concerned that continued use of Coumadin presented a stroke possibility for me. Read More Read Less
