The company's marketing materials describe the drink as a way to kick-start the morning for children as young as 4. The company Web site, adorned with a picture of an elementary school wrestler and a gymnast, says its drink can help a child "develop fully as a high-performance athlete" and fill nutritional gaps "in a sport that is physically and mentally demanding."
  
The drink, called Spark, contains several stimulants and is sold in two formulations: one for children 4 to 11 years old that includes roughly the amount of caffeine found in a cup and a half of coffee, and one containing twice that amount for teenagers and adults.
