That's according to a new study that has found taking vitamin D supplements can aid weight loss in obese and overweight people who are deficient in the vitamin.
Previous studies have shown that vitamin D deficiency is associated with developing obesity and the risk of obesity-related complications, scientists at the University of Milan said.
They estimated that in northern Italy, severe vitamin D deficiency ranges from 6% in overweight people to 30%-40% in the morbidly obese. Almost all obese subjects did not have a vitamin D level in the optimal range.
