I am taking the HydraPharm A'bloc. My stock of the old A'bloc ran out a few weeks ago. I am taking 2 capsules of the new A'bloc per day. I am experiencing no adverse side effects. As far as benefits go, I have noticed that I am sleeping a bit better, my sinus headaches are less of a problem, and a slight skin condition cleared up after a few weeks. I just had my annual check-up. I need to have some blood work done.
