K-Herb Soybean Natto Powder 100% Natural Nattokinase Freeze-Dried Fermented Food Vitamin K2 10.6 oz(300g) (1 Pack)

I bought this 8 times from Amazon and twice I had to return it. I have been using Natto for years and know the taste, smell and the right consistency that it must possess. Day before yesterday I got another packet delivered and instantly knew something was wrong with it. Soybeans when fermented with Bacillus subtilis to make authentic Natto makes it slimy with a typical smell. If you put a small pinch in your mouth, it should feel slimy. If it doesn't and just tastes like mud/earth, it's not authentic or they did not let it ferment long enough. That's what happened to the last batch which is why I asked Amazon for a refund and they thankfully obliged. I will be placing another order today. Overall, the product is good but took off a star for lack of manufacturing QC.

To know if this product is good, it should become tacky or gooey between your thumb and index finger when moistened like in the picture. This indicates the bacillus is active. Return for a refund otherwise. My product was barely gooey but too late to be returned.

Natto has high level of K2. I have 70% artery blockage and hope it will help dissolve cholesterol buildup. Im 77 and not as active as of 6 months ago. Also taking Beet Root, Pomogranite, Tumeric, Ginger, supplements

I am Japanese and my grandma used to try to get me to eat the fresh kind as a kid. She used to eat a serving of it everyday. She ate it because of it's awesome health benefits. I used to refuse to eat it and tell her I didn't need to eat it because I'm young and I don't have any problems with my heart or arteries. I never liked it because of the yucky smell and flavor. I am now older and in my 50's. I have a bit of blockage in my arteries. I tried the powder kind at a market a few years ago and the sample they gave it was mixed with oatmeal... I now have a way I will eat it. Thank goodness there is natto powder and now I eat it often but only in my flavored oatmeal. I mix a serving of it in my apples and cinnamon oatmeal, maple brown sugar oatmeal, etc. I love it! There is no yucky smell or flavor.

Very happy I found this product. As others have noted, the taste is actually quite pleasant, if you use it correctly. What works best for me is to mix it with preferably thick, strong-flavored sauces (tomato sauces, mustards, cheese/vegan cheese sauces, soy/coconut aminos) or dry seasonings (eg furikake with nori and sesame). Condiments that have umami flavored components seem to work the best. The condiments don't just mask the natto taste, this natto powder actually improves and amplifies the flavor. It's especially great over rice. I think if you use a little bit with every meal, it will equal to a medicinal daily dose, which I believe is 1 - 2 tsp a day. If you rely on this product or are thinking about getting it, and are curious about real natto.... I would recommend you curb your curiousity and stay away, because it might make using this difficult to use by association. The "problem" with natto, unless you grew up with it, is not so much the flavor, but that it's accompanied by a wet dish rag smell, and a very challenging texture. If you start to associate the flavor of this product with real natto, you might have a harder time using this. Otherwise it's kind of amazing and delicious. Will update if I notice specific health effects.
