Studies have indicated a possible link between a deficiency of vitamin D and problems with heart disease, insulin resistance and some medical care providers put teens who are obese on high doses of vitamin D in an attempt to slow down or reverse such health problems related to obesity.
However, this most recent research has found that supplements produce no improvement in heart health or lower diabetes risk in obese teens, said a Mayo Clinic endocrinologist.
These supplements might even be linked to an increased level of triglycerides that store fat and cholesterol according to a news release by the Mayo Clinic.
The recent study showed that obese teens following three months of vitamin D supplements did not show changes in body mass index, body weight, waistline, blood flow or blood pressure.
Researchers said they were surprised that no additional heath benefit was found, but they pointed they were not saying that taking the vitamin D supplements was bad as long as they remained at reasonable levels.
The majority of teens who are obese are also vitamin D-deficient. The researchers were just saying that it is still uncertain how beneficial it is to take vitamin D supplements for the overall well being of adolescents.
Excess consumption of vitamin D can result in toxicity of vitamin D, which can cause a loss of appetite, vomiting, nausea and complications with kidneys.
While an association in this study was found between the vitamin D consumption and higher levels of triglycerides and cholesterol, no cause and effect relationship was proven therefore the researchers wrote that a large scale study that was placebo-controlled was needed to see what the effects over the long term are of vitamin D supplement on teens and children.
