My brother started to use some AdvoCare supplements to lose weight quickly and got really sick last night. Did the supplements make him sick or could it have been something else? I know that there are a lot of dangers that come with taking dietary supplements and I just want to make sure that he is being safe. While getting sick will help him lose weight, it’s not a healthy way for him to lose it. Should he keep taking it or should he stop taking the supplement to ensure that it isn’t what is making him sick just to be safe?
