Bests & Worsts Reviews from Amazon

I found this on the clearance shelf at a local grocery store. As I am constantly looking for a great deal, I did a quick search about this brand of CoQ10 online (didn't know much about the substance or the brand prior to that point) and all I found was praise for the product and the substance itself. So, I went ahead and purchased it. Upon first using it I couldn't detect what (if any) benefits I was getting from it, that is until I skipped taking it for a short while. After stopping, I started noticing a dull pain in my chest (heart) returning back to how it was. First of all I didn't even notice the pain subsiding, in fact, I'm not even sure that I fully realized that I had any chest pain at all to begin with, and that's probably because both (coming on, and subsiding) happened gradually as I aged and then as I started taking these 100mg pills. Now, I definitely wanted to protect my heart and pain means something is wrong. I learned from doing a little reading online that the body's natural levels of CoQ10 decline with age. So, I started taking the pills again, and wouldn't you know it the pain subsided again. In fact, I haven't felt that pain in months since I got regular with taking these pills. CoQ10 is now part of my daily supplement regimen and will continue to be for the foreseeable future. Being that this is the only brand I have tried I cannot speak for its efficacy in comparison to other brands of the same substance, however, I can tell you that I've had good results with this one which is why I purchased it again (this time from Amazon).
