I have only been using these for a few weeks, so I think they are working. It takes time for a supplement to fully absorb into your body, so in the next few weeks, I'll have a better idea. Overall, I seem to have a little more patience with those around me. I don't seem to want to yell nearly as often. I plan to keep taking these pills and hope to continue to to see improvement.
I was really worried about any side effects (taste, gas, etc) but I haven't really noticed any. They don't have a strong odor or taste, so that was a huge bonus. TMI warning: I did notice that if I burped shortly after taking them I could sort of taste something off, but it wasn't extremely unpleasant.
