An article in this month's Archives observed vitamin and mineral supplement use in children and adolescents. The researchers wanted to learn more about which children in the United States were taking vitamins or mineral supplements on a regular basis. There were over 10 000 children between the ages of 2 and 17 years in this study; more than one-third of them took a vitamin and/or mineral supplement in the previous month. Interestingly, the study results showed that children who do not really need vitamin and mineral supplements were more likely to take supplements, such as those who were healthy, had active lifestyles, and had access to good food and health care. The study also showed that children who may benefit from vitamin and mineral supplements were less likely to take supplements, such as those who had health problems, less active lifestyles, and limited access to food or health care.
