Low vitamin D may increase risk of death in older adults

Vitamin D is a steroid hormone and a component of a complex endocrine pathway sometimes called 'vitamin D endocrine system' (Medscape, 2012). 

From Reuters:

Low levels of vitamin D may increase the risk of death in older adults, researchers reported in the Journal of the American Geriatrics Society.

Optimal vitamin D levels are considered to be between 80 and 120 nmol/L, although there are no set guidelines. On average, people in the current study had vitamin D levels of 66.0 nmol/L.

The risk of death was 47% higher among those with vitamin D levels between 25 and 49.9 nmol/L, relative to those with vitamin D levels of 100 or higher.

The risk of death due to heart disease was more than twofold higher in people with vitamin D levels lower than 25 nmol/L.

  1. Vitamin D may also be important in preventing a number of other neurocognitive diseases such as schizophrenia, autism, and alzheimer's.
