Answer to Question 1

B
There is some evidence that creatine may enhance energy levels. Ginseng, carnitine, and arginine (an amino acid) have not been found to have any proven effect on athletic performance.

Answer to Question 2

A
Athletes with thin builds, such as gymnasts, may limit their food intake to control their energy intake and may therefore benefit from a multivitamin/mineral supplement. Most athletes consume plenty of food and therefore plenty of vitamins and minerals. For these athletes, adding supplements could result in intake of toxic levels of some nutrients.
