Aisles of health? A pediatrician's guide to vitamins and dietary supplements in pharmacies and supermarkets.

Purpose of review: In recent years, there have been increased discussions among parents about the use of Complementary and Alternative Medicine for kids, specifically dietary supplements and vitamins. While these were originally marketed to supplement nutrient needs, many families have begun to raise questions about the efficacy of vitamins and minerals to treat developmental conditions such as attention-hyperactivity deficit disorder, mood disorders, or sleep disturbances.

Recent findings: Research investigating the use of vitamin supplements generally concludes that supplementation may be necessary in cases of deficiency; additional benefits are minimal. Some hormonal and mineral supplements like melatonin, fish oil, and magnesium have been found to reduce symptoms of hyperactivity, sleep disturbance, and conduct disorders in combination with other interventions. However, none of these therapies rival the efficacy of first-line treatment plans for these conditions. Additionally, overuse may lead to toxicity and adverse effects.

Summary: While many parents may have concerns about their child's nutrient intake, much is still unknown about the dosing, safety, and efficacy of dietary supplements. For deficient children or patients resistant to eating certain food groups, mineral and vitamin supplements may be an effective way to meet nutritional needs. It is important to note that there is little evidence supporting the efficacy of dietary supplement use to treat other conditions nor any benefit for healthy children with a balanced diet.
