Heart and bone damage from low vitamin D linked to declines in sex hormones

A recent study at Johns Hopkins reported what is believed to be the first conclusive evidence in men that the long-term ill effects of vitamin D deficiency are associated by lower levels of the key sex hormone estrogen, but not testosterone.

In a national study in 1010 men, researchers say the new findings build on previous studies showing that deficiencies in vitamin D and low levels of estrogen, found naturally in differing amounts in men and women, were independent risk factors for hardened and narrowed arteries and weakened bones. Vitamin D is an essential part to keeping the body healthy, and can be obtained from fortified foods, such as milk and cereals, and by exposure to sunlight.

The study findings will presented Nov. 15 at the American Heart Association’s (AHA) annual Scientific Sessions in Orlando.
