Physician: The rise in blood pressure that commonly accompanies aging often results from a calcium deficiency  This deficiency is frequently caused by a deficiency in the active form of vitamin D needed in order for the body to absorb calcium
Since the calcium in one glass of milk per day can easily make up for any underlying calcium deficiency, some older people can lower their blood pressure by drinking milk
There is in milk, in a form that older people can generally utilize, enough of the active form of vitamin D and any other substances needed in order for the body to absorb the calcium in that milk.
