Your friend Lee visited a health food store and got interested in taking a supplement. He says that he can make his own decision
because the products must be safe and must work or they wouldn't be on the shelves of the store. What advice would you give your friend? Explain your reasons. (I need a paragraph please)
that not all thing on shelf are save and maybe ask a doctor to make sure he needs to take it or because you don't need something that not meant for you.
