http://enzymetherapies.com/30/serrapeptase/can-you-use-serrapeptase-and-nattokinase-together/ I was diagnosed with a fibroid though rather harmless, it was causing frequent urination due to pressure on the bladder. The only remedy given by doctors was to perform surgery and assured that was the only solution. I elected to hold off and find an alternative solution if possible. I researched these enzymes that work synergistically together and within only a month the frequent urge ceased and upon my next checkup, the fibroid had reduced to half its original size within six months. My doctor was astounded and said he would recommend this alternative treatment to other patients.
