If you are taking Coenzyme Q10
I found out I'm allergic to it. An ingredient in it gave me terrible itchies, all over. Felt like I had fleas. A different region of my body would be affected each day. Apparently it's not very common, but is a one of the side effects. So, if you have unexplained itchyness and are taking that vitamin....you may want to do some experimenting -
Just wanted pass it along.
