Dr. Kumar suggests that it is possible to ingest too much vitamin D, a condition called vitamin D toxicity or hypervitaminosis, which can result in poor appetite, nausea, vomiting and kidney complications. She has been studying the effects of vitamin D supplementation in children for 10 years through four clinical trials and six published studies. Dr. Kumar opted to study vitamin D in overweight teenagers because this population is at an increased risk for chronic disease. To date, her research team has found limited benefit from vitamin D supplements in adolescents.
Dr. Kumar, however, calls for larger, placebo-controlled studies to examine the long-term effects of vitamin D supplementation in teenagers and children. She said, "This is because some studies have shown a link between vitamin D in the blood and improved vascular function. I am surprised that we haven't found more health benefit."
The study appeared online in Pediatric Obesity.
