I just read all 44 reviews on WebMD on Serrapeptase...MOST were positive. Some talked about stomach discomfort...so far I've not had this happen after 2 days taking it. Empty stomach is important for it to work. Finding right dosage seems to be critical. I will hold with 120,000 spu's for a while and gauge myself.

Another friend had reported when she started with "S", the carotid arteries were blocked and after some time, she had great reduction in the blockage.

A person WebMD said the same with with carotid blockages.

One reported on nerve damage reduction.

Many reported on OA and knee issues and sciatic pain reduction. Many claim GONE for a lot of their issues.

Anyway, there are MANY reviews but I chose to read WebMD in entirety.
