Good product at a good price

Posted by Reviewer2808598 on Oct 25, 2007

It helped my wife. It cleared a blocked artery. She was to have surgery, but did not need it after taking nattokinase.

Nattokinase at affordable price

Posted by Reviewer1044325 on Apr 27, 2011

Nattokinase has price spans that can easily triple what you pay for Doctor´s Best . As all of the raw material comes from the same source , Doctor´s Best is the best offer . I am taking nattokinase since two years , 2 a day , and my previous not so good blood data has improved considerably .

Makes tinnitus worse!

Posted by Reviewer1463232 on Dec 21, 2010

Unfortunately, I have tinnitus. When I first used this product it seemed to get much worse. I stopped it for a couple weeks, and then went back on again. Same result; tinnitus worsened, big-time. I tried for a third time of staying off for awhile, til the tinnitus lessened. I took only the minimum doze for 3-5 days and the tinnitus, once again became almost unbearable. It is clear from testing this three times that it was not a coincidence, I'm sorry to say. As for other Doctor's Best products, they are excellent as is iHerb's value and service! I have used iHerb for 8 years now.

Great stuff!

Posted by Reviewer3319292 on Jan 04, 2007

I had poor circulation in my leg from sitting and typing at a desk 8 hours a day and usually not getting much walking. I think I may have been developing some phlebitis since my leg vein (GSV) was bulging out if I didn't keep it elevated. However, after taking this for a few weeks, my circulation got much better! Definitely a good thing to try if you're afraid of paying major bucks for some prescribed medicine. I did start getting some slight heartburn for awhile after taking 2 caps per day for about 2 weeks, but by then my problem had basically completely vanished, so I stopped taking it and my stomach went back to normal.

Massive Thrombus/Clot

Posted by Reviewer2201106 on Jan 28, 2007

I was diagnosed with a thrombus from my left knee to my groin, and the ultra sound confirmed it. I was on coumadin and warfarin, for two years with symptoms of arthritis, which I never had, and a extremely low labido(male)becouse of the drug. Since reseaching Natto, and weaning myself off of the thinners myself, against my doctors wishes. In fact he dropped me as a patient for noncompliance. I have to say I haven't felt better. I have no syptoms of arthritis, thank God! And my libido is back. I have had no swelling in my legs at all, indicating a clot, and I could not be happier with the product. I have told many about the product and my experience with it, and can only hope that the medical profession will open their eyes to the obvious benefits and actions of this enzyme.I have read lately that some are finally acknowledging it's benefits. I again could not be happier with the results.

My use of Nattokinase

Posted by Reviewer3059892 on Sep 21, 2009

I have been using Nattokinase for over a year now along with several other enzymes. I began using it because I was on Cumodin because of a blood clot in my leg a number of years ago. An Oncologist checked my blood and said it did not seem to her that I needed to continue with the blood thinner. My leg would feel heavy and would swell when I lowered my dose of thinner, so I looked for an alternative and came across Nattokinase and Serrepetase as well as Flavenzyme ( I take all 3 ). About a month ago I ran out of Nattokinase and was busy and forgot to order some more. In about 2 weeks I was having swelling in my leg again to the point were it was painful and had to start wearing Ted hose day and night. Once I got back on the Nattokinase (I was checking the mail every day) I took 2 pills twice a day for 3 - 4 days and by the 3-4th day had gotten enough relief so that I did not have to wear the sock any longer. By the way I was taking asprin, Vit. E and everything else I could think of, but nothing helped. I am doing great now and down to 1 morning and night. Needless to say I won't miss reordering again.

Seems good

Posted by Reviewer3102319 on Sep 26, 2012

Im taking these along with serrapeptase, proteolytic enzymes and wobenzym. I think those 3 are having the greatest effect on my problems (painful crunchy shoulder & toxicity problems) so im not too sure of how much effect these are having. but Im going to continue with the nattokinase too. Im feeling so good about my new discovery of these very powerful enzymes that im going to continue with all of them! Great stuff!
