I purchased these for my son who has felt as though he has been dragging for a while. He had a full check up with blood work and while all checked out well, his doctor said he should take a good over the counter (otc) Multi-Vitamin. He happened to be telling me about this and I knew of this OTC Multivitamin because my husband has taken them and found them to be very good. They both are now taking them since I purchased for my son also who commented to me recently that he actually feels more pep in his step, he feels as though he can focus more and all around feels better. He stated, as has my husband that the pills are not any bigger than the other brands, pretty much the same but for some reason they both noticed they, neither one, got the burp with the taste back up or heart burn as they do with the other name brand ones. For the price paid this is a very good multivitamin that last for a month and that is a small investment to make you feel better.
