Good product and great price
on July 11, 2012
I have always been a fan of Nattokinase and Doctor's Best is a decent brand, although there are more potent and higher quality brands around in my opinion. This is coming from a guy who first ordered Nattokinase from the company in Japan tied to the doctor that discovered the enzyme (that package even arrived with Japanese labeling and a little card inside with English instructions). That product was incredible; so much so that you could feel a tingling-relaxed sensation that apparently had something to do with the blood being oxygenated more efficiently or something. I remember having very restful sleep as well as lower blood pressure and just a very relaxing feeling overall. I've never experience that to the same level with the Doctor's Best brand, but I've read some independent studies that affirm it has adequate potency, especially for the price. Unfortunately, I have no idea how to get in contact with the company I used to order from in Japan. I would love to buy it again. In the meantime though, this is a good brand and I appreciate Amazon's auto ship options. I am happy with my order.
