Findings of a new study have suggested that obese teens are highly unlikely to have a good heart health or reduce their diabetes risk by taking vitamin D. The study also warned that vitamin D poses the risk of increasing levels of cholesterol and triglycerides.

Published in Pediatric Obesity, the study showed that there exists a link between vitamin S supplementation and rises in cholesterol and triglycerides.

The Centers for Disease Control and Prevention (CDC) says there has been a huge rise in numbers of obesity cases in the past years. The rates have increased by double among children and quadrupled among adolescents over the past 30 years. One in five Americans is currently obese, said JAMA.

Several studies have clearly showed that obesity-related medical complications are related to vitamin D deficiency. The examples for such diseases are cardiovascular disease and insulin resistance.

High-dose supplementation is recommended by many health-care providers to safeguard the risk of developing such complications.

Dr. Seema Kumar, pediatric endocrinologist in the Mayo Clinic Children's Center, says she has so far failed to confirm any significant benefit from vitamin D supplements in adolescents. She has conducted four clinical trials and published six studies on the subject in the past 10 years.

“We're not saying it's bad to take vitamin D supplements at reasonable doses, and we know most obese teens are vitamin D deficiency. We're just saying the jury is still out on how useful it is for improving overall health in adolescents”, said Dr. Kumar.
