Vitamin D supplementation linked to potential improvements in blood pressure in children

(University of Pittsburgh) Overweight and obese vitamin D-deficient children who took a relatively high dose of vitamin D every day for six months had lower blood pressure and improved insulin sensitivity than their peers who took a lower dose. The study did not show improvements in other markers of cardiovascular and metabolic health, a finding that indicates vitamin D supplementation alone may not be the cure-all for children at highest risk for diabetes and heart disease.
