I have mine from Rainbow Wellness and the tablets are 80,000 units each and I take two in the morning on an empty stomach with no side effects at all. I can see though, that someone with medical issues should proceed with caution. dee

Dianne,
I have used Serrapeptase now, on and off, for years. The brand I am currently using is Doctor's Best. One capsule is 40,000 units. The directions say to take up to three a day, but I always only take one a day and get results. I use them to eliminate spider veins. It does this beautifully.
