Vitamin D supplements may increase levels of cholesterol and triglycerides in obese teens.
Researchers from Mayo Clinic Children’s Center examined the effect of Vitamin D supplementation in 19 obese adolescents aged 13-18 with vitamin deficiency. They treated them with a high-level dosage of Vitamin D for 3 months to assess the influence on their overall health. Moreover, the experts monitored blood calcium, fasting lipids, glucose, insulin and C-reactive proteins (CRP).
After three months of Vitamin D supplements, these teenagers showed no changes in body weight, body mass index (BMI), waistline or blood pressure. The health experts were surprised not to have any health benefit as it is known to have health benefits on endothelial function.
The study concluded that Vitamin D offered no benefits to obese youngsters for cardiovascular health or lowering the risk for diabetes. These supplements are often prescribed to slow or prevent the development of obesity-related medical complications such as insulin resistance. Thus, it is often used five to ten times higher than the recommended daily intake. However, vitamin toxicity can result in nausea, vomiting, poor appetite and kidney complications.
“We are not saying it is bad to take vitamin D supplements at reasonable doses, and we know most obese teens are vitamin D deficient,” said Dr. Seema Kumar, a pediatric endocrinologist at the Mayo Clinic. “We are just saying the jury is still out on how useful it is for improving overall health in adolescents,” she added.
Previous studies have pointed out an association between fat-soluble vitamin D deficiency and obesity-related chronic conditions, such as cardiovascular disease and insulin resistance. The most efficient source of Vitamin D is sunlight and it is also present in various dietary sources such as fish oil and fatty fish. The deficiency of sunshine vitamin can cause osteomalacia in adults or rickets in children. IMAGE/independent.co.uk
