Get your vitamin D levels tested

The body uses vitamin D for a variety of essential functions. Reduced cognitive function is one of the health problems associated with low vitamin D levels.

Those with blood levels of vitamin D less than 20 nanograms per milliliter (ng/mL) lost their memory and other cognitive functions more quickly than those with normal vitamin D levels, according to a research that followed 318 older adults for 5 years. A higher risk of dementia has also been linked to low vitamin D levels. Those with darker skin and those who live in colder areas are more likely to suffer from vitamin D deficiency. To determine whether you require a vitamin D supplement, talk to your doctor about getting a blood test.
