Teens are trying to bulk up on protein supplements. What should parents watch for?

<a href="https://mottpoll.org/reports/teens-and-protein"target="_blank" >A poll of parents last fall found 40% of teens consumed some type of protein supplement in the past year. Boys took it to bulk up; girls took it to replace meals.
