  • A circulatory system health supplement

  • Inspired by the popular Japanese food, natto

  • A natural enzyme that promotes circulatory function

Nattozime is a remarkable circulatory enzyme. Developed by the National Enzyme Company, Swanson Nattozimes is an all-natural enzyme supplement inspired by the popular Japanese health food natto. For centuries, natto has been treasured by the Japanese as a health-promoting food, especially for the heart and circulatory health. Nattozime is a natural enzyme supplement that has demonstrated the same activity found in natto, and it makes a valuable addition to any cardiovascular wellness program.

Rated 4.7 out of 5 by 23 reviewers.
Rated 5 out of 5 by Health Insurance I discovered natto while living in Japan. The health benefits are many. I have been taking Swanson's Nattozime for 9 years, 2-3 capsules on an empty stomach daily. I intend taking this supplement for the rest of my life. Do your research on this one! March 3, 2015
Rated 5 out of 5 by An Every Day Supplement I take Nattozimes every day and feel good about it. September 19, 2013
Rated 5 out of 5 by I use this product daily very good i August 4, 2013
Rated 3 out of 5 by Nattozimes Have been using this product for about 2 weeks. I have not noticed any effects, positive or negative. I gave the product all average ratings due to not enough information to share a good opinion. Will update should information become available. June 3, 2013
Rated 5 out of 5 by Excellent This stuff really turned me around when I first started taking it; I wouldn't be without it daily! May 29, 2013

There is great ease in ordering along with convenience. I highly recommend Swanson's products. April 11, 2012
Rated 3 out of 5 by alternative to natto products? Bought this for parents to help to support the circulatory system. Hope this to be a good alternative to the expensive natto products. Only Time will tell the difference. March 31, 2012
Rated 5 out of 5 by Good for my heart! I think that this product is one that I would not want to be without in my program for better heart health. I have had excellent results with Swanson's brand over other brands. Thanks, Swanson's! March 17, 2012
Rated 5 out of 5 by I am 84 years old , my Father died at the age of 40, My brother died at the age of 42, I do not know what is helping me with my great health but it has to be Swansons Vitamins and the product Nattzimes or Nattokinase. June 8, 2011
Rated 4 out of 5 by Nattokinase I am probably going to try Nattokinase instead of these because I find it inconvenient to wait to 2 hours after or before a meal to take these. I have no problem with this product because I read about the benefits but with Nattokinase you can take them once a day at any time. September 28, 2010
Rated 5 out of 5 by Nattozyme How do you give a good review of such a product, without FREE SPEECH, forget this... GREAT STUFF, EVERYONE SHOULD USE IT ROUTINELY, AND DO RESEARCH ON IT!!! February 12, 2010
Rated 5 out of 5 by I take it without fail Have been taking this product for 3 or 4 yrs. Cheap insurance I call it. The price here IS the best anywhere. September 12, 2009
Rated 5 out of 5 by Very Effective I love Nattozimes. I felt the effectiveness within an hour of taking the first capsule. I wouldn't be without them now. March 5, 2009
Rated 5 out of 5 by Blood Circulation Nattozimes are a low cost natural enzyme that promote blood circulation without the side effects of most anticoagulants. My resting pulse is a low 52 because I work out 30 minutes daily. I have been taking Nattozimes for over two years at bedtime to improve blood circulation during the night when my pulse is at its lowest. February 28, 2009
Rated 5 out of 5 by I have been taking this product approx 5 years and it has helped me to continue my active lifestyle. Dew2, Springfield, Mo. January 4, 2009
Rated 5 out of 5 by Great product for athletes I tend to over-exercise. I've been taking this product regularly for over two years, and I love it. Works better than Nattokinase, in my opinion, for those who overdo it. May 14, 2008
Rated 5 out of 5 by Unbelievable Price ! You cannot beat the price on this product anywhere ! I am happy knowing that this product is available to everyone to use. It is an enzyme formula , that everyone over 30 should be taking and be made aware of. People need to do their homework and research. Then, they will definitely come to Swanson to get the VERY LOWEST price !!! A product like this sells for three to four times as much on most internet sites !! October 11, 2007
Rated 5 out of 5 by natto Nattozimes works just fine. Higher potency is a plus. Might even work better than nattokinase. October 8, 2007
