    For the last 6 months, I have already been incorporating a myriad of other changes including changing to better supplements, dietary changes, eliminating certain things in my environment, incorporating new things, mental emotional physical techniques and practices all to balance my systems. Histazyme is the latest thing I've added because I know I have excess histamine to deal with even after all the other things. I find it most noticable in my sinuses, but, I thought I'd try this in my digestion because I can't take OTC antihistamines. So far, I do notice that it helps! It has a subtle, gentle effect on the body, unlike OTCs. My sinuses are feeling clearer and my system seems calmer since taking it with meals. I can't say my digestion always likes it when I first take it, but, it calms down quickly and I can't always know if I can attribute the initial upset to the histazyme. I'm still healing and balancing things. But, I will continue using it. and... the pills are so small, they are very easy to take. (smile)

    Happy to have Histazyme ..!!

    I really does help me with the intolerance. And I think it is better for me too that it does not have vitamin C.

    Works like magic!

    I started taking Histazme due to having hives that would not go away. This worked immediately and I haven't had a breakout since. I highly recommend this product. Darlene
