More information about vitamin D levels

Vitamin D levels depend on several factors, including location, time of year, diet, and more. Although your body can synthesize this nutrient from the sun, those who live in northern states actually don't obtain any vitamin D from the sun due to the position of the earth in the wintertime. If you’re outside of the normal range, read on to learn more about what influences your vitamin D levels.

High levels of vitamin D:

  • Common in the summertime with sufficient sunlight exposure
  • May result from blind supplementation. Many individuals who choose to self-supplement vitamin D end up taking too much without proper guidance
  • Rarely results from over-consumption of dietary vitamin D, as it naturally occurs in insufficient amounts in only a select group of foods. You can learn more about food sources of vitamin D here.

    Supplementation: No supplementation is recommended with excess levels

Low levels of vitamin D:

  • Common for those who live at latitudes above 37 degrees north of the equator, or individuals who wear sunscreen (remember- vitamin D can only be obtained from sunlight above 37° north from March-November)
  • Very likely to happen if you do not take a vitamin D supplement or multivitamin. Outside of supplementation and sunlight exposure, vitamin D is difficult to obtain through diet alone. 

    Supplementation: Baze dietitians recommend a supplement for those who measure within or below our optimal range, unless you requested to remove it.
