Recently my family has been buying a lot of packaged food because they are cheaper. Almost every meal we have were frozen or came from a can. Then my hair started thining out. I think it's because I don't have enough vitamins so I was considering taking supplement tablets. Our family has this huge bottle that was around for some time. Only....it expired two months ago. I was wondering if it is still safe to take them....?
