Steer Clear of Sports Supplements

Popular supplements

Here is a rundown of some supplements and their safety:

• Anabolic steroids. The claim is that these substances build muscle mass and strength. Fact: They are illegal and unsafe. They boost the risk for stroke, heart disease, liver damage, high cholesterol, and high blood pressure. They also cause testicular shrinkage and breast enlargement in men. Red flags for anabolic steroid use are:

  • Sudden bulking and muscling up

  • Violent mood swings

  • Very severe and widespread acne

  • Hair loss

  • Breast enlargement in boys

• Androstenedione. The claim is that these substances build muscle mass and strength. Fact: "Andro" is a banned substance. It raises the risk for heart disease, cancer, liver damage, and stroke. It can also cause testicular shrinkage and breast enlargement in men.

• Creatine. The claim is that this substance builds muscle mass and may cause weight gain. Other side effects are diarrhea, belly pain, and muscle cramps. Creatine use in children and teens has not been greatly studied. The American College of Sports Medicine recommends that people younger than age 18 should not take it. 

• Vitamins and minerals. Young athletes who are eating healthy don't need vitamin and mineral supplements. But there may be situations, such as special or restricted diets, that may need vitamin supplements. Talk with your healthcare provider about your diet to see if you need a supplement. Some supplements containing the mineral chromium claim to build muscle and reduce fat. According to the American Academy of Pediatrics (AAP), these supplements don't improve sports performance or build muscle.

• Whey and casein protein. Protein is important in an athlete's diet for muscle growth. But studies show that young athletes get three times the amount of protein they need. 

The AAP strongly condemns the use of performance-enhancing substances. It recommends a sensible strength and conditioning program along with a well-balanced diet with proper hydration for the best long-term improvements in performance.
