I've read that when selecting supplements it's best to go with the larger companys, the more reputable companys because of product inconsistancy. I believe it and follow it. Now I was wondering about these vitamins made by the big chain grocery stores or pharmacy places such as(in CA, USA) Ralphs, Sav-on's, Rite-Aid etc. What are the opinions on the quality of products that are made in there factorys? I often see good deals on the pharmacy vitamins, buy one get one free and so I was curious. Thank you
