I was on much less at 2 and a half per day so your blood is much thicker than mine was, indicating you have a very high acid diet and or very poor colon function. Before you go jumping on the natto I suggest you drastically change your diet and start a juicing program and get those readings way down, stop the meat,sugar, and processed foods. See what foods are acid, you are dumping trash into your body and it has to stop. Find out why your readings are so high and correct it. Some one with your blood should probably stay on the coumiden until you correct it with diet, juicing, and colon health.
