Vitamin D provides numerous benefits to your body, and a new study has found that it also helps lower your risk of Alzheimer’s disease and dementia.

A team of researchers from numerous universities based at the University of Exeter Medical School and published in Neurology studied the elderly Americans participating in the Cardiovascular Health Study. By following over 1,600 men and women 65 and older over the course of 6 years, scientists found that those with vitamin D deficiencies were:

  • 53% more likely to develop dementia
  • and 69% more likely to develop Alzheimer’s disease

That was for those with moderate vitamin D deficiencies. For those with a severe lack of vitamin D, the results were severe as well. Those participants with severe vitamin D deficiencies were:

  • 125% more likely to develop dementia
  • 122% more likely to develop Alzheimer’s disease.

The Importance of Vitamin D

The head of the study, Dr. David Llewellyn, said of the results, “We expected to find an association between low vitamin D levels and the risk of dementia and Alzheimer’s disease, but the results were surprising—we actually found that the association was twice as strong as we anticipated.”

Dr. Llewellyn also cautioned that this study’s results were not sufficient to conclude that vitamin D deficiency causes dementia, but merited further studies into the question.

The Sunshine Vitamin

So where can you get vitamin D? It can be as easy as stepping outside, provided the weather’s right. Just 10 minutes of exposure to sunlight can stimulate the production of it by your body, hence its nickname. Of course, that’s not always possible depending on where you live.

Vitamin D is found in numerous foods as well, both fortified and naturally. These include:

  • Fish, like swordfish, salmon, tuna and sardines (also great sources of omega-3’s)
  • Egg yolk
  • Cod liver oil
  • Cheese
  • and fortified foods and drinks like milk, orange juice, yogurt and some cereals

You can also get the vitamin D you need from supplements. It’s best to get those which only contain vitamin D rather than an array of unnecessary ingredients such as those in a multivitamin. Olumia Life does not recommend a daily multivitamin.

What Else It Can Do

The importance of vitamin D in lowering the risk of dementia and Alzheimer’s disease may be new, but there are plenty of other benefits we’ve known about vitamin D for some time. Vitamin D helps us regulate the levels of calcium and phosphorous in our blood, helps to build strong bones and protects against numerous diseases, including:

  • Cancer
  • High blood pressure
  • Heart Disease
  • Osteoporosis
  • and more
