I use Nattokinase due to hyperviscosity, I have severe varicose veins, and hemorrhoids and cannot take blood thinners.
After multiple thromboses, 2 heart attacks, and a stroke, I found out about it on a coronary care website.
5 weeks ago, I began with 4000 FU per day increasing to 4x 4000 FU per day for 3 weeks. Will shortly drop back to 4000 FU per day. I use alongside K2 every second day. My issues have settled, my varicose veins are noticeably less, not hard and painful anymore. ( I have had this chronic complaint for approximately 35 years.)
To say that I am impressed by the results is an understatement.
My heartbeat is still often irregular however I am seeing better results and quicker recovery times.
