Good product; after a couple weeks use it seems to enhance circulation and energy levels.

Thanks for your feedback!

Good moderate dosage nattokinase product

Posted by iHerb Customer on Dec 03, 2014 | Verified Purchase

I prefer this over Enzymedica's "Natto-K" product because the straight NSK-SD doesn't have anything else in it, and dosage is moderate. Supposed to help with lowering fibrinogen levels. (Try earthing/grounding for this too.) Recommend.

Thanks for your feedback!

Instead of Natto

Posted by iHerb Customer on Nov 27, 2011 | Verified Purchase

As I don't plan to include the natto made from fermanted soybeans in my diet and natto is reported to help to prevent and improve cardiovasuclar function,I take these instead. I like the small easy to take softgels.

Thanks for your feedback!
