In vitamin D we trust

There has been a lot of discussion lately about the positive effects of getting enough vitamin D, and equally much lamenting that most Americans aren’t getting as much as they need of the important vitamin to live an optimally healthy life.  Through numerous research, it has been shown that people with low levels of vitamin D seem to have a higher risk of disease overall.  Vitamin D is traditionally known for its supporting role, helping calcium build up strong bones.  But it also can help to regulate and fortify the immune system.  In a very recent study, vitamin D deficiency was linked to a greater risk of developing dementia, Alzheimer disease, and stroke.

In a cross-sectional study involving 318 elders (mean age = 73.5 years) receiving home care, results indicate that vitamin D deficiency and insufficiency may be associated with increased risks for all-cause dementia, Alzheimer disease and stroke. 25-hydroxyvitamin D (25(OH)D) concentrations were deficient (<10 ng/mL) in 14.5% and insufficient (10-20 ng/mL) in 44.3% of the participants. Mean 25(OH)D concentrations were found to be lower in subjects with dementia. Additionally, a significantly higher prevalence of dementia was observed in vitamin D insufficient subjects. After adjusting for confounding factors, vitamin D insufficiency was associated with more than a two-fold increased risk of dementia, Alzheimer disease and stroke (with and without dementia symptoms). Lastly, vitamin D deficiency was associated with increased white matter hyperintensity volume, grade, and prevalence of large vessel infarcts. Thus, the authors of this study conclude, “Vitamin D insufficiency and deficiency was associated with all-cause dementia, Alzheimer disease, stroke (with and without dementia symptoms), and MRI indicators of cerebrovascular disease. These findings suggest a potential vasculoprotective role of vitamin D.”

Vitamin D is turning out to be an incredibly important element for overall health.  Spending (a little) time in the sun, eating a balanced diet replete with calcium rich foods, and taking a quality vitamin D supplement can all contribute to continued good health and vitality.
