Common supplements could harm teens

A new study shows teenage boys could be doing permanent damage to their bodies by using products that are often recommended to them at health food stores.

The study from Pediatrics found about one in 10 teenage boys tries muscle-building products like creatine, and that number doubles if the teens are athletes.  Risks of creatine use include liver and kidney damage, dehydration and muscle cramps.

Creatine can easily be bought at health food and supplement stores.  It's legal, but impacts teens and adults differently.  Researchers just because it's sold at health stores doesn't mean it's healthy for kids to take, and that parents need to be proactive when it comes to what teens are using.  They suggest reading warning labels and making sure teenagers know what they're putting into their bodies.
