3 Surprising Reasons You Need Vitamin D
Published: 05/07/2013

Vitamin D is an essential micronutrient with a central role in maintaining health. I recommend prudent daily sun exposure to support the natural production of vitamin D in our skin as one of the best ways to get enough of this vitamin. But if, like many these days, you have few opportunities to go outside due to work, school or for other reasons, you may be at risk for vitamin D deficiency. Decreased or insufficient levels of vitamin D have been linked to: 

  1. Suppressed immunity: Our innate systems of defense may not function efficiently without adequate vitamin D, allowing increased susceptibility to infectious agents.
  2. Increased risk of chronic disease: Low levels of vitamin D have been associated with a higher than normal risk of heart disease and several kinds of cancer.
  3. Heightened inflammation: Vitamin D is a key cofactor in regulating inflammation throughout the body.

Speak with your doctor about checking your 25-hydroxy vitamin D level and if supplementing may be indicated. I recommend 2,000 IU of vitamin D per day; look for supplements that provide D3 (cholecalciferol) rather than D2 (ergocalciferol). The Vitamin Advisor is a good source of high quality vitamin D products.
