I Started A New Regimen Of Vitamin Supplements Last Week.

I started a new regimen of vitamin supplements last week. Magnesium, PQQ, supplement to help the body produce Testosterone, CoQ10...all from a health food store. Plus my usual low-dose aspirin. I began getting diarrhea a few days ago and it seems to persist. I have a hemorrhoid that is acting up. Could be from new (rougher) toilet paper. anal opening is sore. Stopped using that brand of TP and I cleans with a medicated wipe.
Blood on Tissue after each BM.
